Models for the REFLEX XTR² Model Flight Simulator

The models are optimized for REFLEX XTR² version 5.09 and newer!

The new installers work for these new REFLEX XTR² versions only, and only under MS Windows 7 SP1, 8.1, 10, and 11! The latest version of REFLEX XTR² can be downloaded and tried for up to 14 days for free. A license key can be purchased in a web shop.

The installers should be downloaded into a suitable folder in the first place! In a pinch, they can be moved to a different folder after downloading but before installing. Models and sceneries are stored in subfolders of
  C:\ProgramData\REFLEX\Simulator\
You may create a new folder, for instance
  C:\ProgramData\REFLEX\Installers\
You may as well use your download folder, but then please don't move or delete the installers!

They can be re-executed later to modify the model installations! There are several versions of nearly every model, and you won't need all of them at once. Hence you may delete some versions of a model and install others – just with the model's installer.

The installers can be found in a program menu! (That's why they must be kept in the folder from where they have been executed for the first time; hence download into a suitable folder in the first place!) In MS Windows 7, you'll find the start menu entries in Programs/REFLEX/Models. In MS Windows 10 and 11, they clutter up the REFLEX menu entry, but in Windows 10 you can render them neatly accessible in the task bar:
- Right-click on a blank area of the taskbar.
- Select Toolbars, New Toolbar...
- Navigate to the folder C:\ProgramData\Microsoft\Windows\Start Menu\Programs
- Click on the folder REFLEX and then click "Select Folder".
On the right-hand side in the taskbar appears REFLEX», and clicking on that » will show the submenu Models. (No joy in Windows 11.)

Each installer contains model definitions (except for models without shape), model parameters, some of them special drive sounds, a text (German and English) with some notes, and many of them even demo flights.

Several installers additionally offer suitable sceneries for download and install. These sceneries come from different authors and servers; this is only a service to make installing them more convenient.

Parkflyers and Electric Gliders for REFLEX XTR²

I personally developed and tested the following models for REFLEX XTR². They are very realistic.

REFLEX model selection

The definition files of my REFLEX models are stored in own subdirectories (folders), together with a link to my REFLEX web page. The (in this section) following models, and the demo flights belonging to them, are all included in an installer. You can simply run it and select models to install. There will be links to the model descriptions in the 'REFLEX' program menu under 'models'!

Kazmirski Models for REFLEX XTR²

Ed Kazmirski was the first (1960) model aerobatics world champion with his Orion, which became nearly as world-famous as later his Taurus (1962). Known world-wide is also the trainer Tauri (1963), but not his last competition models Taurus 2 (1964) and Simla (1965). It is interesting to reconstruct and understand the development of those models. Please read the documents belonging to the models, either just here as a pdf file (see below next to the models) or after installation! Links to these comprehensive descriptions will then be found in the menu 'Programs-REFLEX-models'. Demo flights (hit F9 in REFLEX) will show typical flight behavior.

Simla original Simla was Kazmirski's last model, really big (102 in wingspan, later 95 in) but lightweight, kind of an aerobatic motorglider looking impressive in the air. Many versions, also with modern drives; description either here (Simla.pdf, --) or after installation! Including demo flight (hit F9 in REFLEX).

Das Ugly Stik for REFLEX XTR²

Das Ugly Stik by Phil Kraft, enhanced by George Walker, kit by Jim Jensen. Aerobatic sports model, a great classic, 40th-anniversary (and meanwhile also 50th-anniversary) edition (2006/2016) as REFLEX XTR² model. The model is not only the intermediate stage between trainer and aerobat but can fill all three roles, depending on engine power and control setup. Please read the paper belonging to the model, either here (UglyStik.pdf, --) or after installation! A link to this comprehensive description will be found in the menu 'Programs-REFLEX-models'. Demo flights (hit F9 in REFLEX) will show typical flight behavior.

Das Ugly Stik 'German' Das Ugly Stik - mild or wild. Made up like a German WWI fighter, a .60 glow engine and big control throws make it a moderately 'wild' aerobat.
>download package installer (--, 1970-01-01, 5645)
Das Ugly Stik 'American' And made up like an American WWII trainer, a .45 glow engine and small control throws make it a more 'mild' trainer.
>download the complete Ugly Stik package, see above
Das Ugly Stik 'German' with straight wing Das Ugly Stik, also as a true classical pattern model with a straight wing. With a powerful .60 two-stroke engine from the 1970s actually a 'hot rod'. Another variant has the engine slanted ('hot rod 2'), and yet another one has really drooping, that is anhedral wings ('hot rod anhedral').
>download the complete Ugly Stik package, see above
Das Ugly Stik 'Patriot' with rotary engine Das Ugly Stik, still a very good sports model, additionally in a modern German patriot skin. With the Graupner/O.S. .30 'rotary' engine (system NSU/Wankel) even "wilder" than with the old .60 two-stroke engine.
>download the complete Ugly Stik package, see above
Graupner Middle Stick with rotary engine Middle Stick, which Graupner used to introduce the .30 rotary engine in 1970. Because the first version of the engine was weak, this model has a 'middle' setup.
>download the complete Ugly Stik package, see above
Graupner Middle Stick on floats Middle Stick on floats, not with the rotary engine but with a conventional .40 glow engine, which is better suited in this case.
>download the complete Ugly Stik package, see above
Das Ugly Stik 'Czech' with electric motor Das Ugly Stik, as ancestor of all stick models really modern, finally in a skin alluding to the Czech flag. With a ModelMotors AXi 4120 'electric' outrunner motor and a LiPo battery just as well "wilder" than with the old .60 two-stroke engine.
>download the complete Ugly Stik package, see above
Das Ugly Stik 'original' by Phil Kraft Das Ugly Stik, 'original' as described by Phil Kraft in his 1966 Grid Leaks magazine article, with straight wing without dihedral and with the "frills", with the power and the control throws of the 'mild' version. You may get the original article with my annotations in the paper mentioned above (no longer in a separate pdf file), here (UglyStik.pdf, --) or after installation.

Kwik-Fli for REFLEX XTR²

Kwik-Fli Mk III by Phil Kraft, 1967 aerobatic world-champion model. A great classic, 40th-anniversary (2007) edition as REFLEX XTR² model. The model is still up-to-date as a most basic, typical design of a classic pattern model, today more called a sport model. Please read the document belonging to the model, either here (KwikFli.pdf, --) or after installation! A link to this comprehensive description will be found in the menu 'Programs-REFLEX-models'. Demo flights (hit F9 in REFLEX, 'Kwik-Fli...') will show typical flight behavior.

Kwik-Fli Mk III 'original'
Kwik-Fli Mk III, in the original paint scheme, with a .60 glow engine without muffler. With center-of-gravity and decalage as per the plans as a stable flying 'original', alternatively with more back c/g and almost no decalage as a more neutral and 'crisp' setup.
>download package installer (--, 1970-01-01, 4158)
Kwik-Fli Mk IV 'taper'
Kwik-Fli Mark IV, meaning Mk III with tapered wing. With not much decalage as nearly neutral version 'original'. Purpose of the modifikation was better flick ability, which is really better only in the 'crisp' setup. The slightly different paint scheme was traditional as well.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk III 'enhanced'
Kwik-Fli Mk III as still flown by Phil Kraft around 1970. With more powerful engine with muffler as well as retractable landing gear, hence noticeably more weight. As 'retracts' version balanced neutrally since it's considerably faster and more agile than the 1967 World Champonship version.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk III 'retracts'
Kwik-Fli Mk III, only for comparison also with more powerful engine and retractable landing gear as 'retracts' version, but only slightly more weight than the original version. Almost as neutral and fast flight characteristics as later pattern models.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk IV 'retracts'
Kwik-Fli Mk IV as well with slightly more weight, more powerful engine and retractable landing gear as version 'retracts'. Of course even faster and doing even better flick rolls and spins.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk IV 'rotary'
Kwik-Fli Mk IV with retractable landing gear and rotary engine as version 'rotary'. By means of this engine and of reduced fuselage drag, again faster but still not a "rocket" ship.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk V 'rocket'
Kwik-Fli Mk V (that's what I call it) with retractable landing gear, rotary engine, and a thinner wing as version 'rocket'. Now the model is a "rocket" and flies "ballistic", but thanks to flaps can land like the original version.
>download the complete Kwik-Fli package, see above
Kwik-Fli Mk IV 'electric'
Kwik-Fli Mk IV, with electric drive as version 'electric'. Modern aerobatic sport model which is able to gracefully fly any classic aerobatic schedule.
>download the complete Kwik-Fli package, see above
KWIK FLY MK3 'Graupner'
KWIK FLY MK3, the old 'Graupner' version from the 1970s. With more powerful engine and some more weight than the original.
>download the complete Kwik-Fli package, see above
'Flea Fli'
Flea Fli, meaning Mk III scaled down by 0.66 and with a .20 engine, in the original paint scheme. With not much decalage as nearly neutral version 'original' and as completely neutral version 'crisp'.
>download the complete Kwik-Fli package, see above
Kwik-Fli 'Mark II'
Kwik-Fli Mk II, predecessor of Mark III with the same wing. Shorter tail moment arm and smaller vertical tail and elevator show in the flight behavior. With a small decalage stable balanced like the original, with a '.45' engine and a '.60'. The paint scheme was normal for the model.
>download the complete Kwik-Fli package, see above
Kwik-Fli 'Mark I'
Kwik-Fli Mk I, first version of all with bigger wing and more weight. Same wing loading, but rather short tail moment arm and small vertical tail and elevator still don't give optimum flight behavior. With a small decalage stable balanced like the original. The paint scheme was really used for the model.
>download the complete Kwik-Fli package, see above
'Bar-Fli'
Bar-Fli, alternate model for the World Championships. A bit smaller and lighter than Mark III, but with the same .60 engine. Therefore more dynamic and better in wind, in addition to other advantages. With not much decalage as nearly neutral version 'original' and as completely neutral version 'crisp'.

Learn Model Flying with REFLEX XTR²

On this subject, "Learn model flying with a simulator and especially with REFLEX XTR²", I have compiled frequently asked questions and my answers on them in a quite long text file. It was meant for powered airplane models in the first place, but I've later added my experiences with helicopter flying.

The Beginner - shaking in his shoes Fear of Flying? Don't fret, there's the simulator! But how does it work? What to learn with which models? How about landing gear, flaps, side thrust? (Basically about powered model airplanes but model helicopters as well.)
Read/download the illustrated (English) text right here:
>Simulator.pdf (--, 1970-01-01, 6193)

Mentioned in the text are several models and sceneries which are not included in REFLEX because they stem from independent authors. They are aggregated in one package each for airplanes and helicopters with which they can be downloaded and installed automatically and conveniently. These packages should be downloaded to a folder on your hard disk where they can remain. Installers for models and sceneries will be downloaded to the same folder then. You may run them again later to select different variants of models and sceneries. There are detailed instructions in the last section of the text but also here when you click "download package" (and they are slightly different).

Airplanes and sceneries for training Installable trainer airplane models and sceneries (with variants):

GWS Slow Stick WingMaster MFC Silbergrube (both in the picture on the left side)

The model which I used in the late 1960s when trying to learn model flying is available for the simulator, together with a comprehensive description and demonstration flights - just for nostalgic understanding. The demo flights show typical flight behavior of the three model versions. A version with all controls, flaps, and electric drive is even a modern beginners model.

The comprehensive description (VEBF.pdf, --, in English) discusses the model's behavior by means of the demo flights, goes into design considerations, presents the vintage radio and the vintage engine, and discusses the model's practicability for flying schools (and a modern variant named WingMaster). The model as it was actually outlined by the expert (this variant is named FoolProof here), Graupner Taxi, and Engel Telemaster are compared to my model.

VEBF - ancient beginners model VEBF - Very Easy to Build and Fly. Nowadays, this beginner model from the late 1960s is an odd thing, but in the simulator it's an amazing model for rank beginners. Versions with rudder only, additional elevator, additional ailerons as well as ailerons and flaps.

Comprehensive description after installation found in the menu 'Programs-REFLEX-models' or here (VEBF.pdf, --). Demo flights named VEBFn, hit F9 in REFLEX, or at YouTube: VEBF1, VEBF2, VEBF3.
WingMaster WingMaster is basically a full-fledged, modern version of VEBF with all controls, flaps, and an electric drive. It's the virtual rendering of a possible (fictitious) real model which should be a perfect basic trainer owned by a flying school or instructor. Explanation in the VEBF description (VEBF.pdf).

FoolProof FoolProof is virtually VEBF as it actually should have been, at least according to the recommendation in the 1967 Engel modeling catalog. As for VEBF, there are versions with rudder only, additional elevator, and additional ailerons and flaps. For comparison with VEBF, explanation in the VEBF description (VEBF.pdf).

Taxi Graupner® Taxi was the popular trainer model from 1966 to the 1980s, a perfect conventional design. The REFLEX model was made by Bo (Jörgen) Strömberg. One version true to the original with rudder and elevator and another one even with ailerons and flaps. For comparison with VEBF, explanation in the VEBF description (VEBF.pdf).
>install with the VEBF installer, see above, or
>install with the Taxi installer, see further down.
Telemaster Engel Telemaster was perhaps the first beginner and trainer model with ailerons even in 1969. The designer Karl-Heinz Denzin made it unusually big but lightweight so it carried the heavy R/C equipment of the time and still flew slowly. Otherwise it's a conventional design and very good-natured. One lightweight version with good power and a heavier one with very powerful engine. For comparison with VEBF, explanation in the VEBF description (VEBF.pdf).

REFLEX XTR² Models Without Shape

Models without shape means that I didn't create a model file (mod file) for these models. Here I'm offering the flight behavior (parameters, par file), possibly also drive sounds and a simple replacement shape (dummy).

TBX-1
TBX-1 (1965) by Tom Brett, 1962 pattern world champion. Different parameters with a replacement 3D model (appearance), which only remotely resembles the real one. In 6 steps (parameter sets), better and better setup of the model until it really flies proper and well-behaved. Due to the T-stabilizer it has to be flown not too slow lest you lose control! No text file belonging to the model, please read the thread on RCU instead!

Heli Models for REFLEX XTR²

Eric Fague ("Ericoptère") from Switzerland built some nice helicopter models for REFLEX and published them on www.RC-Sim.de several years ago. Actually, they are nice even today and still worth to be flown in the simulator. For the REFLEX version 5.05, and later 5.09, they have been brushed up (and equipped with a heading-lock gyro) and are now – by permission of Eric – re-published here.

HIROBO Shuttle Plus 30 HIROBO Shuttle Plus 30. The HIROBO advertizing claims that more than half of all model heli pilots worldwide have learned to fly with a Shuttle. That may be even true, particularly since the model is still being sold since 1985. Eric's realistic REFLEX model is of 2003. It is really set up for beginners with its 1400 main rotor rpm. The blade pitch is limited to -8° and +8°, but at least you may flip the heli on its back.
>download package installer (--, 1970-01-01, 2255)
HIROBO Shuttle Plus 30 on floats HIROBO Shuttle Plus 30 on floats. Wide undercarriages with inflatable floats made from plastic film have been used quite often by rank beginners. With them, the heli can slide around on the ground without toppling over. Today, rather two crossed sticks with table tennis balls at their tips are simply strapped to the skids. Rotor rpm and blade pitch are the same as on the skids version.
>download the complete Shuttle package, see above

KYOSHO Concept 30 SE on floats KYOSHO Concept 30 SE on floats. This was the equivalent beginners heli by KYOSHO. Eric's cute and realistic model is of 2003 as well. It has a semi-scale body (fuselage) as an addition (Bell 206 Jet Ranger). This is intended to be not only pretty but above all more visible. After all, for beginners the perceptability of the heli's attitude is especially important. That's also why the rotor blades have stripes that look like circles when the rotor is rotating.
>download package installer (--, 1970-01-01, 1917)
KYOSHO Concept 30 SE on floats KYOSHO Concept 30 SE on floats. This version for rank beginners is appropriately set up with only 1400 rotor rpm. The blade pitch is asymmetrically limited to -2° and +10°, so not suited for inverted flight. The heli moves quite sluggishly and docile with this setup. By the way, I prefer this green version on floats. And by the way, it's good also on snow and ice and of course it even "floats" (for instance in the "Baggersee" water scenery).

KYOSHO Concept 30 SE on skids KYOSHO Concept 30 SE on skids. For this version I like the blue painting better, for whatever reason. Anyway, this version with 1500 U/min rotor rpm and blade pitch between -2° and +12° is noticeably more agile and more fun, and so it is more instructive as well.

KYOSHO Concept 30 SE on skids KYOSHO Concept 30 SE on skids. A beginner should switch to the "proper" version on skids right after the first successful sliding attempts on the ground. The floats version is merely intended to avoid frustration (and in reality damage, above all) in the very beginning.

Graupner Star Ranger - Santini Air Graupner Star Ranger in the livery of Santini Air. Eric Fague built this detailed model in 2004. It's quite big (1.41 m rotor diameter) and heavy (4.5 kg weight). It has Graupner/heim UNI-Mechanics and is here set up as a quite agile trainer. Due to the big body with its striking paint scheme also this model can be a good beginners heli.

Graupner Lockheed 286h Graupner Lockheed 286h. The same as the Star Ranger: built in 2004, 1.41 m rotor diameter, 4.5 kg weight, Graupner/heim UNI-Mechanics and set up as a quite agile trainer. This model has a not as tall body with a low landing gear and an unobtrusive paint scheme.

Aérospatiale SA 315B Lama - Heliswiss Aérospatiale SA 315B Lama of Heliswiss. Eric Fague's REFLEX models are from 2003. The Lama is an alpine helicopter and therefore used especially in Switzerland. This model version is quite big and electrically powered.

Aérospatiale SA 315B Lama - Air-Glaciers Aérospatiale SA 315B Lama of Air-Glaciers. This version is just as big and heavy and actually the same, except the color scheme of course and a combustion engine. By the way, Eric used xmodder to convert FMS models by "Logic Wizard" into these Reflex models.

Aérospatiale SA 315B Lama - G2loq Aérospatiale SA 315B Lama, made by Eric for G2loq. It's smaller, the model has no company markings, it has equipment containers under the fuselage, and it's electrically powered. Otherwise it's the same as the other two Lamas.

Hughes 500D - Magnum Hughes 500D like in the TV series Magnum P.I. Eric Fague's REFLEX model is from 2003. The pilot in the TV series, T.C., is sitting in the fully equipped cockpit. The right door can be opened with the landing gear switch. The model is quite big and well-mannered. The big body with eye-catching paint scheme and the cross-striped main rotor blades make for good visibility. I always conceived it as a good beginners heli and it is set up as one. By the way, it looks great in REFLEX's night flying as well as in Ronald Bankert's Fischen night flying scenery.

Hughes 500D Hughes 500D in a typical colorful livery and on high skids. This model (2004) is a bit smaller, more powerful, and doesn't have striped main rotor blades, but it's yet a good beginners model as well. It has interior equipment and pilot but the doors can't be opened. Eric had placed the pilot in the right seat, as usual, but in the Hughes 500 it's different. Now he's sitting in the left seat, like the real T.C. in the TV series.

Hughes 500E - PEKA Hughes 500E as replica of the PEKA Hughes by Günter Knipprath. This was one of the first model helicopters with JetCat turbine drive, big with 2 meters main rotor diameter. The REFLEX model from 2005 shows the innards of the original model with the turbine. Typical PEKA paint scheme, German registration. All these models have the high skids.

Hughes 500E - PEKA Hughes 500E analog to the PEKA Hughes. An original's Breitling paint scheme and Swiss registration. The flight characteristics were not adapted to the recent REFLEX versions and thus partially unusual, but not too bad. I virtually set a flybarless system in the parameters, now the models fly very good.

Hughes 500E - PEKA Hughes 500E analog to the PEKA Hughes. Yet another original's paint scheme and Swiss registration. Besides I rendered the real rotor blade count for even more realistic flight characteristics. Hence the Breitling version's 2-blade tail rotor is marginal and needs more rpm. This version's 4-blader is all right with less rpm.

MD 520N - PEKA MD 520N analog to the PEKA Hughes. Simply in blue with Swiss registration. The NOTAR system as a tail rotor replacement can not be rendered in REFLEX and is in turn replaced by equivalent tail rotor parameters as realistic as possible. I set some expo on all four PEKA versions.

Bell 205 - LA County Fire Bell 205 of the Los Angeles County Fire Department. In 2004, Eric Fague converted this detailed model from a FMS model by "Logic Wizard" into a REFLEX model using xmodder. It's quite big (1.85 m rotor diameter) and heavy (8.5 kg weight). The big body with its paint scheme and the cross-striped rotor blades make for good visibility. That's why also this model could be a good beginners heli.

Bell 206 - Ayers Rock Helicopters Bell 206 of Ayers Rock Helicopters. In 2005, Eric Fague converted the three 206 models from FMS models by "Logic Wizard" into REFLEX models using xmodder. This one has 2.50 m rotor diameter, weighs 17 kg, and is powered by a gas engine. Back then Eric wrote it corresponds to the Jet Ranger III XL by Vario (with gas engine, today with electric motor or turbine).

Bell 206 - Swiss registration Bell 206 with Swiss registration. These 206 models are relatively coarse and have a somewhat fuzzy paint scheme, but they are nice and quite good fliers. This one has even 3.00 m rotor diameter but weighs only 15 kg, as well powered by a gas engine.

And he added a short demo flight (hit F9 in REFLEX, Bell 206 Santini Air).

Airwolf Airwolf from the same-titled TV series. Eric Fague built this model in 2006 and published it in 2007. It has normal size (1.55 m rotor) and weight (5.2 kg) and I turned it into an electric helicopter. Eric set up also a quite big version (3 m rotor, 20 kg weight) with turbine and interesting flight characteristics. Except heading-lock gyro and expo for the tail rotor, I didn't change anything.

Jürgen Dreyer (DL3FY) built quite a number of airplane models for REFLEX. That was several years ago and he built a few helicopter models as well (all his models published on www.RC-Sim.de). At least one of them is nice even today and still worth to be flown in the simulator. For the REFLEX version 5.09 it has been brushed up and is now – by permission of Jürgen – re-published here.

Mil Mi-24C Hind Mil Mi-24C Hind. Jürgen Dreyer probably converted this detailed model from a FMS model by "Logic Wizard" into a REFLEX model. Here it's set up like the modern model by HeliClassics: rotor diameter 2.5m, weight 25kg, turbine 12 kW. No idea if that is realistic but in the simulator it flies nicely and like the real model in a video.
Something special: The rotor mast is now tilted forward and to the left side – like on the original. Hence the fuselage is level and upright in flight (not tilted) and the helicopter takes off straight forward.

REFLEX model parameters


The 'engine sounds' of my REFLEX models are more characteristic for the model's drive than for the model-drive combination. The sounds should therefore fit any other model with the same drive. If you only want the sounds, here are all sound files combined in a ZIP file. It includes short descriptions of the sounds and recording instructions (ReflexSoundsBE.txt).

Model and Scenery Management for REFLEX XTR²

On this web page, more than 60 additional models for REFLEX are offered, nearly all in an installer program that can be run via an entry in the Windows menu "Start - All Apps". That gets confusing (and Windows 10 and 11 are no help) so the model manager offered here can be a help. It neatly categorizes the models, downloads them, and installs them after you just ticked their entry, and it even removes them if you un-tick them. It manages already installed models by running the respective installer again (if you simply tick another checkbox) so you can install other variants of a model. The categories and the order are the same as on this web page:

Additional to the sceneries included in REFLEX, there is a bunch of nice sceneries made by independent authors. They offer their respective sceneries at their own websites so you have to find, download, and install them. These tasks are taken care of by the scenery manager offered here. It neatly categorizes more than 40 sceneries, downloads them, and installs them after you just ticked their entry, and it even removes them if you un-tick them. It manages already installed sceneries all the same. The categories:

Stability Calculations with Plane Geometry

The geometries of my models were measured and entered into the spreadsheets Plane Geometry by Blaine K. Beron-Rawdon. The moments of inertia of the models were measured too and used in the calculation of stability data as far as 'Plane Geometry' can do this. Models not available to me were measured from drawings published in the WWW, moments of inertia were estimated. The spreadsheets 'MeasureC/V' and 'DesignC/V' from 'Plane Geometry' with the model data are available here. With respect to the copyright, all formulas are deleted and there is no documentation of 'Plane Geometry'.

Electric Drive Calculations

The motor coefficients are derived from catalog data and measurements. The propeller coefficients from 'JavaProp' are used to calculate the data of the whole drive. In some cases also flight performance data as well as climb and glide polars are calculated. The spreadsheets with all formulas are available here. If you find any error please drop me an e-mail.

Instructions for Installation:

Download the installer package to a folder on your hard disk were it can remain!

When you run it, you can select models and sceneries for training. There are predefined selections: for basic, intermediate, and advanced training; limited or extended choice of models and sceneries; or simply full selection. You can always select each and any model or scenery directly by ticking it, that’s called custom installation then.

When you proceed now, the installer will show you a list of more installer packages that have to be downloaded first in order to install the selected models and sceneries. These packages are all ticked already, just for your information, so you can click the Install button right away.

A lot will be going on now, but virtually nothing is shown in the installer window. But you can have Windows Explorer running behind the installer window and displaying the folder where the trainer-installer package resides. Then you will see the additional installer packages showing up after they have been automatically downloaded. You still can’t see that they are automatically run then in order to install the selected models and sceneries. Either way, just patiently wait until disk activity ends!

Now you will find the installed models in the Model Selection (F2 key) of REFLEX XTR² in the “Aircraft | Trainer” branch. This “branch” or “group” is supplemental to the groups in which models are actually stored. It just pools the trainer models so you can easily find them, and it holds just “links” to them.

All models, that is variants of a type, are stored in their own groups, named after the model’s or the original’s manufacturer or, in case of my models, in sub-groups of “BE”, named like the model type. You can find and select them for simulation there (F2 key, “Aircraft”) as well, just under slightly different names.

All installer packages downloaded to your hard disk will stay in place. One way to run them again is double-clicking them in Windows Explorer. But there should be now a folder named REFLEX in the Windows menu "Start | All Apps". It holds uninstall entries for all installer packages, re-select entries for many of them, as well as links to model descriptions for several of them. So you may easily read about a model, modify your selection of variants, or remove it completely. You can save that for later, though.

For now, just think about running the trainer-installer package again. You will want to do that when you are learning to fly airplanes and want to step-up, for instance from basic to intermediate training, or to extend your model selection. In the former case, the previously installed models are removed from the “Trainer” group and the newly selected ones installed instead. In the latter case, the newly selected ones are just added. You can also add or remove models to or from the group by ticking or unticking them, respectively.

Models you remove from the “Trainer” group by running the trainer-installer package again will remain in their own groups. Even if you substitute variants of a model by other variants, the variants removed from the “Trainer” group will remain in the model's own group as well. There you may install more variants of this model by running its own installer package but – as said above – you can save that for later.

For sceneries, there is no supplemental group with “links”. In the Scenery Selection (F3 key) of REFLEX XTR², you can find them in their respective country groups, which are Austria, the Czech Republic, and Germany for the sceneries suggested here. Only one of them has variants to select.

If you are ready now, you may click on the link below to download the trainer-installer package. Your browser should show a dialog box where you can choose an appropriate folder on your hard disk to store the installer package. If it doesn’t and stores into your Downloads folder by default, you can either move the downloaded installer file in Windows Explorer or just leave it in the Downloads folder. In this case, make sure that you do not remove it later.

You may run the installer directly from your browser (from where it usually displays downloaded files), if you are happy with just waiting until the installer has done its job. But if you like to watch how the additional installer packages are downloaded (like described above), you should run Windows Explorer, display the chosen folder, and run the installer package from there (by double-click).

Instructions for Installation:

Download the installer package to a folder on your hard disk were it can remain!

When you run it, you can select models and sceneries for training. There are two predefined selections: compact or full. You can always select each and any model or scenery directly by ticking it, that’s called custom installation then.

When you proceed now, the installer will show you a list of more installer packages that have to be downloaded first in order to install the selected models and sceneries. These packages are all ticked already, just for your information, so you can click the Install button right away.

This “branch” or “group” is supplemental to the groups in which models are actually stored. It just pools the trainer models so you can easily find them, and it holds just “links” to them.

For now, just think about running the trainer-installer package again. You will want to do that when you are learning to fly helicopters and want to extend your model selection. The newly selected models are added to the “Trainer” group then. You can also add or remove models to or from the group by ticking or unticking them, respectively.

Models you remove from the “Trainer” group by running the trainer-installer package again will remain in their own groups.

Instructions for Installation:

Download the installer package to a folder on your hard disk were it can remain!

When you run it, you can select scale models scaled 1:3.5. There are two predefined selections: compact or full. You can always select each and any model directly by ticking it, that’s called custom installation then.

When you proceed now, the installer will show you a list of more installer packages that have to be downloaded first in order to install the selected models. These packages are all ticked already, just for your information, so you can click the Install button right away.

A lot will be going on now, but virtually nothing is shown in the installer window. But you can have Windows Explorer running behind the installer window and displaying the folder where the Scale35 installer package resides. Then you will see the additional installer packages showing up after they have been automatically downloaded. You still can’t see that they are automatically run then in order to install the selected models. Either way, just patiently wait until disk activity ends!

Now you will find the installed models in the Model Selection (F2 key) of REFLEX XTR² in the “Aircraft | BE | Scale 3.5” branch. This “branch” or “group” is supplemental to the groups in which the models are actually stored. It just pools the Scale 3.5 models so you can easily find them, and it holds just “links” to them.

All models, that is variants of a type, are stored in their own groups, named after the original’s manufacturer or, in case of my models, in sub-groups of “BE”, named like the type. You can find and select them for simulation there (F2 key, “Aircraft”) as well, just under slightly different names.

So you may easily read about a model, modify your selection of variants, or remove it completely.

Also the Scale 3.5 installer package can be run again to modify your model selection in the “Scale 3.5” group. You may add or remove models to/from the group by ticking or unticking them, respectively.

Models you remove from the “Scale 3.5” group by running the Scale 3.5 installer package again will remain in their own groups. Most of the models have more variants which you can install in their own group by running their own installer package.

If you are ready now, you may click on the link below to download the Scale 3.5 installer package. Your browser should show a dialog box where you can choose an appropriate folder on your hard disk to store the installer package. If it doesn’t and stores into your Downloads folder by default, you can either move the downloaded installer file in Windows Explorer or just leave it in the Downloads folder.

Installing the model manager:

Download the app to a folder on your hard disk were it can remain! If you already have installer packages for models, this app should go into the same folder. Then it can manage the existing models and any further installer packages will go into this folder as well.

When you run the app, there will be instructions how to use it and, finally, how to run (find) it again (or even remove it).

When you have clicked "Install" (only once!) in the app, there may be a silent download but then the downloaded installer program should show up. There you have to select variants or just confirm until that installation ends. This procedure will be repeated for all models which are to be installed in the first place or for whom other variants have to be selected. Finally, the model manager will show another dialog page to end the whole process.

You will find the installed models in the Model Selection (F2 key) of REFLEX XTR² in their respective manufacturer groups, either model manufacturer or (in case of scale models) full-size manufacturer, or in my group "BE" and subgroups. These “groups” as well as the models in them are listed in alphabetical order.

All installer packages downloaded to your hard disk will stay in place. You may run the model manager again (via its app menu entry) in order to add models to your REFLEX XTR² installation or remove some from it. Re-installing models does not require additional downloads. Most of the installer packages can also be run again to add or remove variants of the respective model (for instance different paint scheme, different scale, different drive).

If you are ready now, you may click on the link below to download the model manager. Your browser should show a dialog box where you can choose an appropriate folder on your hard disk to store it. If it doesn’t and stores into your Downloads folder by default, you should by all means move the downloaded app file in Windows Explorer – before you run it – to the folder where you store the model installer packages.

If the app has been downloaded into the right folder right away, you may run it directly from your browser (from where it usually displays downloaded files).

Download the model manager app here.

Installing the scenery manager:

Download the app to a folder on your hard disk were it can remain! If you already have installer packages for sceneries, this app should go into the same folder. Then it can manage the existing sceneries and any further installer packages will go into this folder as well.

When you run the app, there will be instructions how to use it and, finally, how to run (find) it again (or even remove it).

When you have clicked "Install" (only once!) in the app, a lot will be going on but nothing is shown in the app window. But you can have Windows Explorer running behind the scenery manager and displaying the folder where the scenery installer packages reside. Then you will see additional installer packages showing up if any have been automatically downloaded. You still can’t see when they are automatically run in order to install the selected sceneries. Either way, just patiently wait until disk activity ends and a new scenery manager page appears!

You will find the installed sceneries in the Scenery Selection (F3 key) of REFLEX XTR² in their respective country groups, like Austria or Germany. These “groups” as well as the sceneries in them are listed in alphabetical order.

All installer packages downloaded to your hard disk will stay in place. You may run the scenery manager again (via its app menu entry) in order to add sceneries to your REFLEX XTR² installation or remove some from it. Re-installing sceneries does not require additional downloads.

If you are ready now, you may click on the link below to download the scenery manager. Your browser should show a dialog box where you can choose an appropriate folder on your hard disk to store it.
