Dollar store baseball bat fuse with a coro V elevator and a smack wing. Cutting your own foam wings will save you some $ and its not hard. You may have to spend an dollar or even 2 (oh my) to sacrifice an extra bat ...or 2 to make the fuse stiffer under the wing sadle area. Still a light plane. Look at the RCCA web site for generic smack wing plans, esentially the same construction method as the Avenger and others. "Smack " tape onto foam. I think protecting the radio etc helps keep repair time down. Tank can go in or on the side of the bat
Snapping is common with these SSC planes and less elevator throw as stated helps.
When I flew SSC, a little, a few years back the more competitive guys kept the weight right at 2.5#
