I need to get this off my chest, it's been bugging me for the last 25 years. This may or may not be interesting.
Back in the mid-80's a co-worker/flying buddy and I pieced together a c/l plane from parts found wherever we could find them, and came up with a somewhat unconventional, super ugly great flying stunt ship. The goal was to simply have something for my friend to fly. I wish I had a picture of it but the flying qualities of this plane were so good that I still have a pretty good recollection of the construction and set-up so that I could probably build another from memory... if it comes to that.

Let me describe it to you, along with the "design theory", and then tell you about how it flew.
We started with a Ringmaster (S-2 version I think) wing that was salvaged from a crash. My friend needed a fuse so I dropped off a 4" wide plank of balsa (or was it 6") thinking that, when I came by the next day, he would cut himself another RM fuse. Wrong! He turned that plank on edge and cut out a hole for the wing, left the piece the full 4" width from stem to stern! By the time I came over to help he had the new "fuse" glued to the old wing. He did at least round off the front corners (think GeeBee R1 side-view except way uglier) I helped him with a standard looking stab/elev of about 25%.
Mono wheel ala Flite Streak, to keep the ugly theme going.
We found an old Testors McCoy 40 so it was put to use because it was all we had. My friend said he had a set of store bought Sullivan lines labeled .015x60'. They seemed a little long so we measured them. 70 Feet! neither one of us knew how to finish lines so we left them full length.
Big surprise it turned out super heavy! Can't remember if we weighed it but trust me it was a rock on a string, nothing left to do but fly it.
We ended up with a small, ugly, overweight (we thought), more than adequately powered plane with a huge amount of side area on super long lines.
From the first flight the Series 21 McCoy 40 ran perfect in a strong, steady 4-stroke and the plane flew beautifully! That little plane with it's tall fuselage kept those 70 foot lines tight! I'm sure the good-running engine had a lot to do with our success but the thing was flying way better than expected. It went over the WO without a whimper and the square loops and eights, not perfect but close to correct geometry, seemed huge! The corners were probably not super tight but, because the plane was so small and the lines so long, the corners appeared tight in relation to the overall maneuver. The impression was that we were
waiting for the plane to get to the next intersection/corner.
My friend and I took turns flying many patterns with that ugly little plane that day. That "set-up" was
FUN. I need to build another....
