I purchased a set of 3" tracks for use on a large rover and noticed I could not find the 2.5" stand-offs used between side pieces on your site. Turns out there aren’t that easy to find!! I found them elsewhere but do you guys stock them?
Also, what are the nylon bushings (Part# NB-01 ]) for? My rover doesn’t seem to need them (or does it?). 
Looks like I used a 1.5" and a 1.0" together to make the 2.5" standoff. 
We sell both of them.

The bushings are used on our Tritrack chassis as illustrated.

Hope this helps.
I see. I plan to use nylon blocks under the track for support as I’d assume the bushing may wear out on this 25lb robot.
These tracks are quite awesome btw.

thats an acer netbook on top for scale.

thats a Banebots 540 motor and gearhead
Wow! Gulp!

I’d suggest you put the drive motors at the track high points so you will have better ground clearance if needed. Are you going to use the acer computer on the bot?
Putting the motors on the high point would make sense however then the computer would need to be a good 5" off the top deck. The entire idea of using tracks for this bot is purely aesthetic so I thought why not. It will likely operate in parking lots and grass predominately.
And yes the netbook does all the thinking (vision, gps, remote control, etc…).
A BS2 runs the secondary motor control into a motor controller I haven’t decided on yet.
Thanks for the advice though
Should be an interesting project. You may be the first person on the board to put a mini notebook on a bot. Has a lot of potential. Will the mini notebook be running windows?
Wow 8) , that looks big and awesome!
I didn’t know the threads was that BIG!
With the price of netbooks going down i thought it would be a natural progression in hobby robotics. Unfortunately it does run on Windows. That’s what to BS2 sub board is for. I can limit the overall speed and shut down the motors if the computer decides to have a ‘Bill Gates moment’. Its all programmed in VB.net. Overall dimensions are 17.5" wide X 19" long with a deck size of 12"x12". I originally had the J5 base in mind for this project but the computer is 10.5" wide and weighs 2.2lbs. I didn’t want to make the center of gravity too high and have half the allotted weight be the computer with no room for batteries.
