it's a standing offer if you have any questions. Airplane setup, contest logistics, judging criteria, flying technique, Im more then willing to show what I have learned over the past 15 years.

Bobby, when I first started doing rollers I was using elevator only to fly the airplane through the circle. I saw Jeff Szuber using the rudder to slide the airplane while upright and inverted and elevator while at knife. I tried it and made a huge difference. The other ting is to make sure you don't have a cross couple between rudder and elevator. Most airplanes do. An aft CG will make it worse. I run slightly forward CG and a rudder to elevator mix so that a rudder input will only yaw the airplane. without this when doing an inside roller the airplane wants to go to the outside on the first quarter of your roll.
