Skywarp was a pretty basic mod; I shaved the sides of the key part to loosen the fit, and used a small piece of styrene to give a better surface fit for when I glued it onto the switch. After trimming off the main part of the key, leaving just the hexagonal nub, I filed it smooth and glued the key in with superglue. Now I can pop up his launcher in jet mode without the key.


Brakedown was a trickier one - there were a couple of things that I thought needed fixing. For one thing, his 'racing sabre' couldn't be activated in his car mode, since the key port was completely obscured by his body. For another, I thought the 'sabre' (which looked to me to be more of a ram) seemed kind of ridiculous in robot mode, as the way he held it made it look awkward to use.
To start with, I converted the sabre into a rifle by trimming the spike off the end and drilling out the end to simulate a gunbarrel.
Then came the tricky part - rigging the weapon so it could be deployed in both modes.
I made the same modifications to Brakedown's key as I had to Skywarp's, but this alone wouldn't do the job; the point of his backplate extended too far forward in vehicle mode, obstructing the weapon, and the switch on the weapon fell too low to be reachable without some sort of probe tool, which would have defeated the object of the exercise.
I trimmed and filed the point off the backplate till the switch fit into the gap. Then I built up the top of the switch with spare bits of styrene, fusing them into place and filing them to shape.

I've also done the key mod on Ransack, but I've got more work to do on him before I post it.
