RE: VMAR Mig 21

I do not understand your comment on the rudder, my rudder servo is in the rear and the pushrod is approx 6" long, I think you mean the nose wheel stearing rod is 4'-0", Easy solution use a seperate servo for the nose wheel stearing in the belly bay, I mean there is so much room in there, I also put my Throttle servo in the bay. Elevators are on Ailivators in my programmable transmitter, helps with control at slow speed, as does flapperons, unlike most I use them to give washout to the wing when landing i.e. up not down.
