Shawn,

Highly pre-fabbed wings with live hinges for the ailerons. I believe Bob also took out the undercamber on the leading edge cuff to improve the landing characteristics. Stabs and vertical fin/rudder get the same treatment. It's sort of the same thing they did with the F-86 in that things were redesigned and simplified to make the airplane buildable with minimal tools and space. The fuse is offered in a silver gelcoat too so if you want. They also put the new Super Bandit landing gear system in them, a new fuel system, and a new component layout to make installing things easier.
