Yes, I will be doing some testing… but this type of static testing can be very misleading.

Endurance tests can be helpful for someone that is not familiar with calculating the correct power system. In reality it is much better to first calculate the all up weight of a craft, then determine the proper Motor / Prop / Battery Pack to fit the specific objective.

My experience is that the performance charts that T-Motors puts together for each motor are pretty close to reality. If I were to do a thorough test, I would need to do 50 or more flights with various configurations of weight, prop and battery options to provide any meaningful data for each motor.

T-Motors has done basic testing for us – we can see what thrust is for a motor at various throttle settings using one type of prop. From this, we can get real close to what is needed.

If you need assistance in selecting the proper power system, feel free to give me a call.
