Testing the temperature inside the plane
As the waterproof plane does not have any venting, we need to make sure that the temperature inside the plane doesnt get to high.
Test Setup
Mainly the ESC produces a lot of waste
The temperature was measured directly at the ESC - which was the hottest point in the plane.
| Time m | Temperature ° C | A | Vo | mAh |
|---|---|---|---|---|
| 0 | 24 | 4.24 | ||
| 10 | 40 | |||
| 15 | 43 | 4.22 | 15.35 | 1200 |
| 20 | 44 | 4.14 | 15.18 | 1500 |
| 25 | 45 | 4.06 | 15.00 | 1850 |
| 30 | 45 | 4.01 | 14.87 | 2150 |
| 35 | 45 | 3.91 | 14.71 | 2460 |
| 40 | 45 | 3.85 | 14.54 | 2770 |
| 45 | 45 | 3.74 | 14.32 | 3130 |
Voltage of the battery after test: 14.30 Volt (3,57 V per cell)
Ende: 50m - 3.70A, 14.16V, 27% anzeige - 3.500 mAh
1min - 100% Thrust - 46° C - no stronger temperature on 20A current.
Battery capacity
Charging the battery: 4500 mAh
