I started the tests with a homemade inertia wheel using a sensorless motor:



The motor does not want to start, no matter how much I spin it initially. Basically, it means that for a sensorless motor, testing with an inertia wheel is difficult. Loading with a propeller will give all the information necessary as sensorless ESC cannot go over a certain level of torque.

I will now start to test with a 540 sensored motor and a proper racing ESC.
