Glad To Hear Your Building!!
My personal favorite would be the Goldberg Falcon 56. Great flying plane due to it's fully symetrical wing And stab. The build is almost fool proof since the wing is a constant cord and the leading and trailing edges are notched out for the rib placement. Thae stab is also built with the nitches for the ribs. Its a shoulder wing and strip aile. but with a thick airfoil it slows down nicely for landings, and you could do a lot of aerobatics with it. You could also add the flaps if you really must.
The Telemasters are nice too. A bit more of a build on the fuse, but I had a 40 size back in the 80s that would fly backwards in a 15-20 mph wind! That made it worth building the fussy light-weight fuse.
What ever you decide, let us know and start a thread. The guys in here love to share the knowledge that they have discovered over the years.
