Spektrum DX6i -> Lemon RX DSMX -> PPM - Problems

Okay, so I have soldered the R8 back on and i tok some pictures.

As of the mission planner, I can´t say I got any further. The PreArm-error is still there and when i try to hit “Play” i get "FAILURE: Unsupported CMD: 252, if i try to hit the “Take of” button i get "FAILURE: FailedCMD: 22

Any ideas?

btw. The reason why the power cable is disconnected from the ECS´s is because they make a lot of noise when there is no signal present.
