RE: PICA WACO BIPE
A suggestion (I'm assuming you've got the kit, not a completed plane). I'd put a separate aileron servo in each lower wing. The kit's system of bellcranks works OK, but it gets sloppy over the years (mine is 15 years old and just about worn out). Fiberglass specialties does have a really good cowling. The kit's interplane struts really aren't functional. If you've got a big enough vehicle to transport this with the wings attached, I'd recommend something that attaches more securely.
