Knew I was going to do this as soon as they announced we were getting him. Kind of a test run, mostly to show it can be done.
There are two mods here; the first for the jet mode. I cut the wings and attached the VTOL engine blocks directly.
The second is the wing hinge, which I modded for robot mode. Real simple: you round the bottom of the hinge the same way as on top so you can rotate the wings back and still have room for his arms to hang straight down.
before pic--you can see the hinges rounded at the bottom
after pic, all finished.
