there was a model called the "Phony Tony"
Awful thing - a real rule stretcher
At least in naming it the designer admitted what he was up to.
Our club used to run a competition for longest glide time from a set engine run. Obviously you want a fast climbing model with a good glide but all l had at the time was a Kwik Fli III ( good climb, poor glide) and a Super 60 ( poor climb, good glide)
Obvious, I thought - combine the two so I strapped the SS wing onto the flat top of the KF fuselage. The resulting very short flight was totally uncontrollable and put me off biplanes for years.
