I found someone who copied the 40 plans for me, and traced the rib carriers from the kits to produce rib patterns. I'm going to build at least two of them. The first will be a 35AX powered hand launched, as light as possible. For the second I'd like to do retract gear (B&D air) and maybe a Jett 35 rear exhaust.
I don't know what it is about this design that is so attractive. I've had four of them, 2 of the 10 size and 2 of the 40, and all of them were destroyed in crashes, but here I am again.
