Okay, I've moved on to some of my other drones. The one I'm working on now is a King Kong 90GT. It flies but it drifts quite a bit to the right. I checked all the trims and center points in my x90d+ and all is good. I successfully calibrated the motors in BF and the took a look at them in BLHeli. Something looks wrong in there. I'll attach a photo showing motor 2 and motor 3, Motors 1 and 4 look very similar to 2. Can anyone tell me what the picture reflects may be wrong with motor 3? Thanks.
