I just picked up a Chief Aircraft Experimental Surplus Plane to create a drop plane. I will probably put it on the shelf for the time being, as I currently have a BTE Superflying King which is a great drop plane. But this Chief plane looks like it would work great, they had only two of them and won't have them again, so I thought I would go ahead and get one.
Composite fuselage, wings & stab
Engine box is built and installed
Hinged with Robart type hinges
Minimal hardware included
Horizontal Stab: 58"
Wing Area: approx 2800 sq in
My SFK has a DA100 and flies great.
I included some pictures of the SFK and the Chief Experimental Plane
