A fair amount of work is required to make it scale. The ailerons need to be changed to bottom offset hinge, the kit is top hinged.

Interesting, Sig's 1/5 scale is top hinged too. I don't know why Busa & Sig do that, as differential throws are just as easy to accomplish with a scale bottom hinged arrangement. I almost sprung for an unbuilt Sig 1/4 kit at the swap meet this morning, but the box was ragged & water stained, and the plans had already been cut up. I wasn't too confident in what I might get out of it.
