I'll bite
Here are a few of my favorites:
The first is a Great Planes .20 Cub with a clipped wing (engine and radio removed, but otherwise flyable).
The second is a Great Planes Super Decathalon powered by an Enya .50CX.
The third is a Great Planes RV-4 powered with an OS .46 FX.
The fourth is a scratch built Corbin Baby Ace D powered by an OS .40 FS.
