It wasn't a major hassle, just that it didn't track straight and needed aileron to keep it in line. I can't remember the exact elevator pushrod setup, is it some kind of T bar from the servo to connect to the arms on each tailplane pivot? Differential elevator is always a problem when one servo drives two separate elevators, due to the rotary motion of the disc. One way of solving it without carrying two servos, is to mount the servo on its side, that way the rotary motion of the servo disc is up and down instead of side to side so there is no differential movement.

Another weight saving strategy is to try AAA cells for the Rx instead of AA.

I seem to remember that flying had just two throttle settings - full throttle, and one notch back from full throttle to land! It's a little wing to carry a big engine, retracts and 5 channel radio. If you can knock a pound of weight off it it will transform it. I would not have been bidding for it if I didn't think it worth having again, but do be prepared to have to fly fast at lift off and landing approach, it is a very small wing!

Ahh memories! Those two photos were taken way back in 1987 and I hadn't looked at them for years.
