I am assuming that those are 4 inch wheels? If so how many stages are in your gearbox and what are the speeds.

looks pretty good. how much does it weigh?

The weight is about 28 pounds right now according to Inventor, Yes the wheel's are four inch, They have the same dimensions as the Andymark one's with a custom lightening pattern. The gearboxes have all the same internal's as a standard Andymark Toughbox, so the reduction is 12.75:1. this makes the final speed pretty slow (around 4 fps) so I'll probably half the ratio.
