How many bands on the Avistar. My short lived plane had 8. I would go into a gentle turn and all of a sudden it would pull super hard and I'd have to shove the stick forward. In the end I had the DR set so the elivator only moved about 1/8 inch up and down and it still did it. Is this because the front of the wing lifted up? My son nick named it the Crazy-8 plane.
