Response:
1.Yeah, this sucker took a week to do, I'm still surprised it could actually be wired up.
2. The three 'layers' of super glue gel and two layers of super glue I used on both the motors and extra transfer gear rod is to ensure they don't come off.(You would have use a hammer to break them off or pick the glue off with a knife.) But your right Snake mod, all that weight in the back wouldn't let it climb steep angles without falling backwards.
the yellow gear was from my Zcar since I ran out of blue gears.
3. I didn't quite think about that jazz, I barely understand gear ratios and all that other stuff. But I guess I forgot to mention that I wired up the second motor in reverse so that it can add its motion to the first one, so the motors don't fight each other, at least that, but even then it still won't have speed, as you said. But I never thought of doing what you just mentioned, that's cool, I'm definitly gonna' do that since I'm lookin' for speed. Should have some pics soon. Thanks for saving me the time and trouble of trying to making this hack job work.
