3mm to 5mm sleeve
 

someone please help, i need the adapter to run a mod pinion on my 3mm shaft. i have seen people with sleeves that turn there 3mm shaft to 5mm. i just cant find them.

take a look at www-newfrog-com ,to see if it can help u.

Wouldn't it be easier just to find a 3mm pinion of the same size? 5mm is pretty odd except for in the larger scale cars. Even then it should be pretty easy to find the right sized pinion.
