Hi everyone, im new to the whole robot thing so i decided to make a simple box/push bot. Basically the exact same as 'TORNADO' but without the spinner.

Im using 2 XU-1's with red wheels and a Sabretooth ESC. I just realised that my model XU-1 is the XCD-140 not the XCD-12 as in the wiki page.
So that, im guessing, is the reason we had to do some cutting and stuff until we got the wheel mounted and looking pretty. The problem is that the motor spins but the wheel takes time to turn, and by touching the wheel it completely stops with the motor still spinning. Is this our fault? Or a different way of making the XU-1s that it designed to annoy me?

Thanks heaps for any help, Collo

hey the clutch isnt locked properly.

you need to take all the little ball bearings out of the front of the gearbox and replace them with at least 4 grub screws.

ill get some pics if you dont understand.

Hey Glen, you don't need to take the ball bearings out......

Nah just kidding. You do.

Yeah not locked, if you've got grub screws already you havn't screwed em in enough.

YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

Have alook at Anderson Robot Wheels in the Market Place thread

Potential issue for anyone running Red wheels on Andrew mod adapters.

They have changed the mold.

Must have finally worn out.

I picked up some new wheels for Rat and noticed several differences.

Smaller diameter tire, 5 spokes on outside instead if 3, inner black bit has shoulder and slightly different dimensions even the color is slightly different.

If you need the old ones best grab some while there still on the shelf.

Yes they are slightly different have just compared the two with my calipers.

Diameter is 90mm down from 95mm. Width is still approximately the same. Not sure about the inner black bit as I don't have that in my old wheel.

the old ones had a 1/2 inch hole when you take the black bit out my adapters are self broaching for the key ways as long as the hole is 1/2 inch or 13mm dia you can hammer them into any plastic or ali wheel and they cut their own key ways

Or take a look at Andersons robot combat wheels ;->
