I had to raise the rudder pushrod position so as not to bind the connection to the servo. Also installed a latch to secure the hatch. I did not trust the magnets. I connected the rudder and elevator servo to a receiver and checked out the centering. They were both A-OK. Then connected the pushrods to the rudder and elevator. They operated also A-OK. How about that landing gear with Dave Brown Lite Flite 4 1/2 in Wheels?
