Finally, one more issue: I heard people complaining about the pushrods but I was curious as to why. Upon not finding any metal pushrods in the package besides 10 or so 6'' pushrods, I looked in the manual and found that they use nylon tubes with the metal pushrods at the ends! Tiny nylon tubes? As pushrods?! I'm sorry, that sounds crazy to me. The tubes will flex like crazy and have a ton of friction in the pushrod housings! What should I do? Buy real metal pushrods?
Plastic pushrods are quite O.K. if mounted properly. They need support at regular intervals and one should strive to leave as little of the inner plastic pushrod exposed as possible. For example, do not cut the outer sleeve flush with the fuselage side, instead let it extend backwards as close to the elevator and rudder horns as possible. The exposed part of the inner plastic tube should have a metal pushrod inside.
Unless you are flying in climate conditions with severe variations in temperature and humidity trim changes will be very small. I have built and flown a a couple of SSEs over the years and all of them used the supplied plastic pushrods without any problems whatsoever.
