Something besides CG?
Is there anything beside CG issues that could be causing my Seagull Spacewalker II ARF to be wildly uncontrollably in the air? I mean, on its maiden flight it just squirrled all over the air and the best I could do was bring it in for a crash landing. There was some wind that day but that wasn't the main problem. It's now all repaired and ready to fly again -- just as soon as I can figure out what happened. I've done some simulations in REalFlight and it sure looks like a CG problem but the balance was right on at the recommended location (which is at the spar at about the 30% MAC location).
