Was wondering if this motor would fit in a SC10

[Desert Rc]

So I was running a medusa 4800KV motor with a 5mm shaft in my sc10 with a 32 pitch spur, slipper eliminator, and ball diff. I was blowing tranny parts left and right with this motor. I was trying to find a replacement motor and was wondering about this one?? I know nothing of hackers but I saw the 3.17 shaft and wondering if this would fit the bill. With the 3.17mm shaft I can put the slipper back on and save the tranny on the poor sc10.
