Frank,

Sideview, my Orion, design Ed Kazmirski world champion 1960 pattern, but a view procents bigger and some modifications to make a “sport plane” of it. The plane is aerodynamic the same.

30 years old inverted ENYA 60 4 C engine, span 69”, weight 10 lbs.
In my thread "Redesign and reconstruction of the Oldest Taurus on Earth" you found some pictures of the modification of the cooling of the engine.

I think the plane would not fly so easy without ground effect.
My advice, use an old REAL taildragger with as short as possible mainlegs, when you want to fly on grass with retracts, so you have profit of the ground effect.
