Hello there, as I was building my copter, I realise that one motor was spinning way slower than the other motors, and upon checking the servo outputs on Mission Planner, the PWM output of one motor was much lower than the other. Could I ask if anyone has any idea of how to callibrate the ESC?
We are using the t-motor AT 55a 2-6s ESCs for our quad. Thank you!!
How did you realized that? without props? Using stabilize mode and playing with the throttle stick?
Hi there,
Yeap, when we were playing around with the throttle stick on acro mode, we went to the servo output tab on mission planner, and saw that there is an obvious difference in PWM output.
Furthermore, when we did a motor test, when we set it to 5%, that particular motor didn’t spin, but when we increased it to 20%, that motor spun for a bit.
As there will be. No conclusion can be drawn from that test.
My motor No.3 is last to run and first to stop, always. It’s seems to go slower on arm then others but once in the air, it does the job.
Just calibrate ESCs then do not care.

DId you calibrate it with BLHeli, or you used the inbuilt on on miession planner
yeap!! each of them is connected to each motor!

I suppose they will work but it was the wrong choice. Looking the programing options it’s not clear what you would want for multirotor use.
And of course forget about BLheli.
