"I too have integrated the APM 2.5 to the DJI Flamewheel 550 airframe and found that it does not hold position as well as the WKM. Does anyone have the PIDs for this frame?"

"Jos, can you send me what your final tunings were for your hexacopter?  It would be a good place for me to start.  A screenshot of your settings would be perfect. Thanks   Jason  "

"Randy, Decreasing RATE D to 0.002 and P to 0.090 ,after 4 short test all OK. thank you so much for your advise."
