Hey, thanks for replying, I was worried that I'd offended everyone asking for some advice
Ummm, actually I removed a millimeter or two (literally) of the stops for the range of the cannons swing motion and lowered his canons a bit so that save for his two largest shoulder spikes he fits perfectly into the shell; sides, bonnet, boot and top, heck even the wheel placement shouldn't get in the way of moving parts (And wheels always cause me problems with the extensive work. Treads are easy, wings usually more so... WHEELS are evil;))
When I didn't get any replies I finally ended up just making a blank 'mold-shell' from heavy construction paper, that way I can rearrange how the pieces need to be cut and folded before doing the final cuts, and I can make several trial shells before the final as well, to check range of motion as the paper is the same thickness as the shell plastic.
I know I probably could make him a spaceship but I liked the idea of him being a car *shrugs* But then again my favorite Binaltech is the 'Jaguar/Ravage'

I looked at his 'alt' mode for a long while and finally went with car-mode (and I know it seems silly) as I liked the idea of this Ravage being able to interact with more characters, and spy up close and personal with a bit more ease, leaving Soundwave to watch from the silence of space.
(Never let a kitbasher get bored, we're dangerous ^v^... There's not a single TF I own that hasn't gotten some sort of work done if they're not MIB
