Looking to convert an MBX5T

[Shimmy]

Cool, nice lookin truggy.
What KV is that 1520?

Ok, so... 1717... no, haha.
I was only looking at the 1717 because castle has it on sale for $70 (unless it's some BS price)?

I have read about the need to shim up the diffs after converting to electric, hopefully I get it right.

Castle/Tekin may be the better setup, but if I went that way I would be looking at well over $300, the setup I'm looking at will be about $150-$170 or so.

Whatever I may save later down the track is kinda pointless to me anyway.

Castle charges $50 flat rate to repair correct?, its probably about $15-$20 to post, do that both ways (unless they pay to send it back?) and I am looking at about $80-90... I could buy another esc for that.

I already have a leopard motor (a 3650 2930 for my Losi Desert truck).
I have no complaints about it (great motor), the main thing I am thinking of now is would I notice much of a difference from a 4064 and 4072.
If I go the 4072 way, I'm not sure if I should get the 1500kv or the 1250kv.
I am thinking the 1500 KV would be more fun.

Also, a wye wound motor would be best for a truggy right?
