I have one motor that starts more slowly than the others when arming. The motors spools up fine with a little more throttle and the quad flies just fine. But it nags at me that something is wrong that could result in it quitting midair.
I have 4006 T-motors running off of a Qbrain 25a 4-in- esc controlled by a PH. I have gone through the MP motor calibration several times with no change to the one motor.
Would a cold solder connection make it behave this way? I had to cut and solder plugs on both the motor and esc.
Any other thoughts on cause, or should I just fly it?
