Hi all,

I’m building a hex F550. When performing motor test, 5 of my motor will start spin at 14% except one. The one only spin at 15%.

My question, is that normal or is it harmful? Please advice, thank you.

Regards,
Leslie

I will assume you have calibrated the ESC’s
1% is very little, and may not make any difference in flight.
There can be a lot of factors affecting the spin up of a motor, variances in the ESC, motor bearings or other forms of physical drag on the motor.

Your first flight test is the final answer to your question.

I have calibrated the ESC as per the page that you sent to me. I will try to take off today. Thanks for your help again.
