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.
Specs:
