This Bridi RCM Trainer RC kit is NIB. The original stack of parts still is intact. There are 672 square inches of wing, so use a 40; maybe more, if you want to make it less "Trainer" and more "Sport". Box art promises 6 hour assembly time! (Well, maybe, but I couldn't). Shipping in the US double boxed and insured will be $16, and international sales welcome.
