The ACE 4-40 Bipe is one I hadn't thought of. Actually, I didn't remember there being a 40 size bipe. I remember the 4-60 and the 4-120. Not very pretty planes, but they were very easy to bash and they flew great. Does anyone know the size of the plane (wingspan, length, wing area)? What type of airfoil did they have?

MrMulligan, thanks for the reply, but I don't do ARFs (at least I think those are ARFs, but I'm a bit out of touch with the current offerings).
