How do I make a spool?
I'm going to run mod on a tight track, so I need a spool for the Pro 4. No company has begun to distribute a spool for the Pro 4. Can someone describe to me the process for making a spool out of a standard Pro 4 diff? And advice or links would be greatly appreciated. Thanks Chad

I wouldn't recommend CA glue, it makes your parts useless afterwards. Here's a pretty good way to "convert" your ball diff to a spool.
1. Remove the diff balls and diff rings.
2. Replace the diff rings with a piece of header card that is cut to the same size (that thin cardboard that the name/price/etc. of a part is printed on)
3. Screw the diff back down really tight.
(Note: there may be another/better way to build this.)
This way, the diff acts like a spool, but if forced, it will give a little, so you don't snap parts. Hope this helps.

Thanks for your advice. Is there a way to bolt a diff shut? I've heard of this, but never been told how to do it?

cos when you turn a corner the outer wheel has to travel a larger curcumfrence than the inner wheel so the diff alowes the wheels to spin at different speeds when cornering......................................do you get it
