I have the Sherpa K650T from Shade Tree and the throttle works backwards, the throttle works fine in all other aircraft. I have use the "/" key and "Shift + /" and they reverse the direction the throttle moves but I still end up with reverse thrust. I have talked to Shade Tree and they don't have an answer. When I disconnect the Arduino the throttle work correctly so as far as I can tell the problem is here. I have tried all the different throttle options in the configurator with no luck, any help would be appreciated.
