This is awesome. I had to go check out your blog to confirm a few things... You mentioned here "components of Six-Gun," but shared no photos that showed if Six-Gun himself could be built...
Alas, seems you were less successful with Scamper. Not to take away from your awesome accomplishment, but it is a bit disappointing that he doesn't have his own robot mode, instead just becoming an alternate torso to connect to Six-Gun componants. I am guessing it was just a matter of what you could make at that scale that works, but to me Six-Gun and Scamper should be separate characters.
(Slammer
also being an extra Six-Gun torso, though, I just see as a bonus, since I don't worry about Slammer needing to transform in the first place!)
Any gripes about Scamper aside... awesome job! I love it!
