RE: STUPIDLY THIN / STUPIDLY FAST...?
Howdy Joe....yep, everything seems to have an upper limit....except for how good homebrew can be made to taste.
If this air frame ends up sleek enough it will allow testing the Enya and ASP engines with more propellor choices and maybe engine mod ideas. The idea is to have an airframe that is less of a limiting factor than the power plant.
