With the receiver and battery on the provided tray, wrapped in foam and secured with the velcro, the push rod tubs don't have a straight line to the rudder servo for the nose wheel, or the throttle linkage for the throttle. They both bind and the servers "chatter" when moved. I'm ready to dispose of the tray entirely and figure out a way to velcor the receiver and battery directly to the fuselage bottom (inside, of course).
