ddubya,

On his plane, it had a tendency to pull towards the belly, therfore by adding a little spoileron mix, it corrected the problem. IN your case you would have to mix flapperon in instead, since your pulling toward the canopy. But before you do so, just check out how your plane reacts to flaps being activated. If it tends to pitch the nose down with flaps, then it should help.

There may be a better solution out there, hopefully one of the RCU aerobatic gurus will pop in???
