I've bought a new brushless motor for in my son's Traxxas Slash 2WD.
The old Titan brushed motor died after 2 months and I thought a new brushless motor would be a nice step up!
Problem now is that the new motor has a 5mm shaft (instead of the standard 3.17mm).
What spur and pinion do I need to get this baby running?
(The brushless motor (Hobbywing) comes with a 19pins 5mm pinion)
Please help as I am new to this kind of stuff!
