Do you know how many colour schemes there are for Thunderwing?
There's the G1 and Generations toys, then the IDW and Dreamwave versions, and there's at least three versions in the Marvel comics....
So in the end I gave up and made my own scheme up.
It's a Universe Jetfire with a Generations Thunderwing head.
His chest ribbing is cut-up pieces of a pipe from a Batman & Robin Bane movie figure.





I'm working on a way to incorporate Jetfire's boosters into an 'ultra mode'.
