Continous run test for 6:00 minutes

One of the most important test was conducted today, the continous run test. I started full throttle with nearly full batteries to check the power consumption of the motor and the heat dissipation.

The result is very convincing: at full throttle with the 30" propeller I operated the motor for exactly 6:00 minutes. The cells were depleted afterwads to 22.7V that means 3.78V (LiPo 6S).

That is a fairly good value and there would be still some reseserve power. As the cells had seen some short tests before, I estimate the total operational time of about 7:30 minutes.

That is also more than initially expected.

The ESC has a shut-off controll for low voltage to protect the battery, so there is no problem of damaging it with to low voltage depletion.

Another important point is the temperature disipation. I checked with an infrared thermometer and the motor housing is getting to 78ºC at the end of the test. The power cables are also getting warm, around 40ºC. The battery itself only changed to 35º, also the electronics is not getting any warmer.
