the mod.
On the motor mount you can just order up the 1/4" end grain
carbon lam. like is listed at this site http://cstsales.com/carbon-panels.htm
good luck
Yes, this is the correct mod and should be done both top and bottom; basically moves the high point of the airfoil forward. The Tapered ailerons on the Stickit IV were a concession to the masses for kitting purposes, they just flat looked better. For performance, the ailerons should be rectangular for more aileron area. Tapering in the tips as suggested stops a lot of gear breakage.
