I don't think it's a trainer fuse, the thickness under the wing is too thin. Most trainers have a lot of material there to handle rough landings with out breaking the fuse in half. It doesn't look like any trainer kit fuse I've ever seen.

As others have mentioned, it has "stick" lines, but that's an awful wide variety of planes.

It does have the bottom-mounted horizontal stab of the origional ugly stick. And the moments look about right. But the wing thickness and control surfaces sizes are totally wrong.

I'd say a modified Ugly Stick kit, with a thicker wing (and therefore hacked wing saddle), and totally changed tail surfaces to get more control authority. The very thin horzontal and vertical stabs look like what you'd get if you tried to keep the over all surface area of the stab+control surface the same, but increase the size of the control surface on an Ugly Stick. (and used a square rather than round vertical stab/rudder)
