Thanks to all in advance for Help
Trying to setup up an APM 2.8 board, GPS, external compass quadcopter firmware V3.2.1 with a Flysky FS-T6 transmitter and Flysky FSR6B receiver.
I am using the 4 position switch mix that a gentleman posted on this board for the FS-T6. I have calibrated radio, acell, compass, so on in mission planner, all good. When I use mission planner to set up 4 different flight modes from the FS-T6 switches I get the correct different hrz reading in the flight mode column all is correct, the flight modes change with the switch positions on the radio.
Problem is when I take it out and fly the quad, it flies well in first setting (Stablize) but as soon as I flip one of the assigned flight mode switches (Pos Hold, Loiter, or RTL the quad goes crazy taking off in one direction or another, sometimes there is no controlling it even with the switch turned back off?
I have tried standard parameters Throttle Mid Position adjustments but no help (I had another Flysky radio I had to set Throttle Mid Position to 400 from the default 500 to get switches to be recognized on another quad with a different APM.)
sorry if this has been asked before,but I did not find it.
Appreciate any help, or suggestions
