-They’re stickers, and easy to remove.
-The shell fits on a char-g, but it stops the rear wheels from turning. Probably wouldn’t take much to get it working though.
-The tyres fit, but they’re too big and stop the plastic bit over the circuit board clipping in properly. And the front tyres made my Tomy go wobbly.
-Motor is wired back to the battery/circuit board.
So there’s not really anything that can be used for a char-g.
There’s a few bodies available. I couldn’t identify what they were. Most of them sort of look like Mitsubishis… but crossed with WRXs and Mercs.
