Remove your pushroads. Set your epa values on both end to 110% and read out the signal values of ppm. Change your radio config.

Set back your epas and pushroads and check.

It worked me.

Thank you SilaS. 

On the radio control wiki page, it does not talk about end points. I calibrated my radio ppm values with the end points set in my Tx to limit the servo throw. Is there a better way of doing this?

When I add a +4 rudder trim on the Tx, told the rudder stick to the right, I lose all control to the rest of the servos including the motor. If I pull the rudder in the other direction with the +4 rudder trim, all servos work. When I add a -4 rudder trim, all of the servos work when the rudder is pulled both left and right.

Last time we flew, we had aileron trim and the elevators gave out on takeoff in manual mode, but control was gained after a couple seconds. I have not been able to achieve the same results with the aileron trim on the ground, but definitely have consistent servo problems when rudder rudder trim is added.
