Dont know how its possible to use this gains: Trappy's DJI NASA 900KV 9x5 4S3300mAh settings - 166/135/131/179 and 188/176
I have the same setup and 2 other guys too, and if you use more than 150 throttle with the 900kV and SimonK ESCs the copter wobbles as hell during ascend.
My setup: Dji Naza 900kV SimonK ESC 9x5 4S3600mAh settings - 135/125/120/160 and 140/130 and it flys fast and smooth without wobbles
