T9X and the APM2.5+ weird problem

Posted by Gústaf Gústafsson on March 25, 2013 at 2:35am

Hi there,

I have the T9X unit and a new APM 2.5+ with the 2.91 firmware. I have a very difficult problem, it seems my channels are switching in mid flight. When I switch on the units everything is ok and the vehicle takes off corresponding to the correct inputs (it works just as it should in the mission planner) but then suddenly, at least pitch and roll start working like in reverse. I have tried setting up a new mode in the T9X, starting from scratch but the problem is just the same. When this happens I just try to land it as quickly as I can...

I have no idea if it´s the transmitter or if the problem lies with the APM. Anbody heard of such a glitch?

    Check in Mission Planner, flight modes screen. Make sure you don't have 'simple' mode clicked, this causes the copter to move away from you if you pitch forward, back towards you if you pitch back, no matter what the orientation of the copter. So if you have turned 90 degrees  it will appear that your controls have swapped!

    Hope that helps!
