Wrong. These planes were designed that way to allow the full
size competition planes to fly on the edge of a stall to allow their
quick snap maneuvers. The small tips don't hold the lift as does
the center section. I've found reflexing both ailerons up 1/8 to
3/16" creats the washout to prevent the tip stall. Also, too much
elevator travel made my Caps snap abruptly. I coundn't figure
out why the plane would fall out of a sharp upward inside loop.
Once I put in the washout, I lost some of the quick rolls but it
sure did make landings a lot more enjoyable.
