I have the unbuilt Kyosha 3. The quality of work on the tail are pretty bad, it would be very easy to duplicate. I can fax the outline of what you need if that would help. Rigging the alierons up will not help they are not the primary source of lift, about the first 15% of the leading edge are. You have to wash out the wing or twist it, leading edge down, trailing edge up. The real 3 tips stalls worse than any airplane i"ve flown, the good news is that it stalls at about 55 knots. Bob Metz
