I saw a strange propeller airplane that looked some were between a stealth plane a boomerang and the horton g0?

i saw a propeller plane fly over my house. it was a cross of a stealth airplane, a boomerang, and a Horton-G0229. to me it seemed like the Horton but as the shape of a boomerang. i could tell it wasn't aerodynamic because it went really slow. also it was a little smaller than the Norton. i could probable guess this is a copy of the prototype stealth airplane by the Germans in the 40s.(part of it is at the ud var hy museum in Washington D.C) does any one know what it really is?
