CBH:
No, the tailpacks are free from any interference, they do however rely on a fairly unslightly and long slot running each side of the backplate tho. And I am questioning the strength and stablity of the sliders themselves...they work fine, but I feel they might break easily and they're kinda wobbily. I did have to slice away some of the shoulder joint parts to make way for the peices I added for the wings to slide into.
Jessee:
First of all, big thanks to you and Rob for getting those parts out...I really didn't want to have to scratchbuild them. As for the wings, I added a small nub to the very tip of them(on the top side) as both a rotation point and a sliding guide. I then built up some guiding rails to hold the wings in place(its kinda hard to explain but as soon as I more batteries for my camera, I'll take some more detailed shots), the wings slide down/back first, and then fold in together. Another update should be along shortly.
