So i'm having a weird problem with Taranis, dragonlink, ppm, or pixhawk I'm not sure really what it is.
I'm using a Taranis controller, dragonlinlink TX/RX PPM to pixhawk. My quad flies great, tested in all modes. all channels operate correctly in the RC calibrate screen.
I'm using 6 channels, but gimbal tilt is mapped to channel 7, with channel 6 doing nothing.
My problem is, when I move the gimbal slider all the way in one direction, to make the gimbal look up... my pitch and roll stick become reversed. IE when i push the pitch stick forward, instead my quad rolls to the right. and when I pitch back, instead my quad rolls to the left.
Now if i move the gimbal slider back down so the gimbal looks down, the controlls return to normal, and pitch controls pitch, roll controls roll.
I tried to recreat the issue while the quad was disarmed. While lookling at my RC calibrate screen, i moved the throttle to mid stick to simulate hover, and moved the gimbal slider all the way up to make the gimbal look up. When i move my pitch stick forward, pitch moves as it should, not effecting roll at all on the RC Calibrate screen. But sure enough, when i try to actually fly again.... When I make the gimbal look up, my pitch stick starts making the quad roll instead.
I'm guessing this has to do with PPM framing or something with my PPM signal, but that's really just a guess and i'm not sure. My taranis PPM setting is set to CH 1-10, 26.5ms 300u +. I've tried changing it to CH 1-7, and also increasing my pulse legnth, but still the same problem.
Any ideas? I'm lost.
