QGroundcontrol.
1. Drop down “connect” menu on top right corner, and select pixhawk on
COMx(depending on your computer configuration)

■Calibration for 250 frames
Because QGroundControl doesn’t originally support 250 frames, at the first
step of calibration, you should choose DJI Flame Wheel 330 as a
replacement. Before taking off, it is necessary to adjust parameter of airframe
330.
Choose PARAMETER Tab, adjust PID parameters in Multicopter Attitude
Control, set MC_PITCHRATE_P, MC_ROLLRATE_P to 0.1，
MC_YAWRATE_P to 0.22.
