Hi gervais,

 great work with DJI-Phantom/APM integration (http://diydrones.com/profiles/blogs/what-a-phantom-should-look-like-inside).

I've a doubt about DJI RC transmitter modification; you explain to mount a 4k7 potentiometer to K2 connector to have channel 6 ready for tuning.

I did it, but under Radio Calibration I see Channel 6 takes only three fixed values when I move knob (same values like using 3 position switch), so channel 6 doesn't takes a modular value between min and max, but takes only three fixed value (like 1200-1500-1800).

Maybe I was wrong in something? In the potentiometer value ? Or do I need to set some value in APM Planner ?

Thanks in advance for your help, gervais.

Hi Simone, I did my Phantom goes APM http://fpv-community.de/showthread.php?26841-DJI-Phantom-Umbau-auf-Arduflyer-APM-2-5-Flight-Controller-vom-Anf%E4nger-f%FCr-Anf%E4nger  15 months ago, and the FW was initially AC 2.9 later 3.01.Don´t remember too much anymore.

Your problem though sounds familiar, as I experienced lately with AC3.2-rcx @ F450, PIXHAWK and Graupner RC, where I haven´t been satisfied with Autotune, and tried the CH6 tuning again, just having a poti which acted as a switch... Some guys had the same prob: http://diydrones.com/forum/topics/channel-6-pid-tuning-problem and my fix was a complete new FW setup (going to plane back to copter and re-doing all the calibration including RC including CH6 pot,which I might have forgotten @ my first RC calibration.

Hope that works for you as well,

Best Regards, gervais
