I had to have these two in my collection, so this is the project that got me to start customizing. I saw a pretty unimpressive Alpha Trion and Vector Sigma set on ebay for a ridiculous price (well over $200) and thought I could probably make one better for under $20. Well it ended up closer to $35, but mostly because I screwed up my first version of Vector Sigma.
This is an excellent idea. How did you go about make Vector Sigma? As for A3, I never would have seen this coming. How did you attach the wings? Probably doesn't really have an altmode I'm guessing?
For something to get you into customizing, you have managed to raise the bar. This is an impressive piece. You have to tell how you made it and what out of. Beast Hunters Ratchet is a given but Vector Sigma and the key. Awesome doesn't even begin to describe this.
