having trouble with showtime pulling to right when full elevator applied at 1/2 throttle. I have a os 120 with 16x4. Is this a cg issue or elevator halves not in proper balance? Please help............

I am sure that some more learned people will respond to this, however, IMO, it is most likely an elevator halves not maching problem. I had to spend some considerable time getting mine set right on my Showtime, but when they were finally right, it made a big difference. There have also been some instances of the incidence of the wing and stabs being not quite right. If you have an incidence meter, check this as well -- be sure to firmly secure the aileron or elevator when you are measureing them as they are large and a slight amount of space from level will produce a wide variance in your readings.

Try reducing elevator throw! It dos'nt take much to snap out with to much elevator. Mine did the same thing, I just keep reducing low rate on ele till it stopped.

thanks for the info..

My elevators have equal travel, I never really slam it on full rates, guess the only time
may be doing a wall, Guess it pulls somewhat, but to me nothing unsual...
I really like the way the showtime flies... I'm running the YS 110 17X4W
