Mugen MBX5T Conversion - Suggestions/advice

New Project...

I was thinking to go for 4s and mm/ubec (just easy to use & I don't fancy the quark mod )

I'm hoping Mike will come through with a motor mount for me else I'm going to try to see what I can come up with at home...

Worst worst case i know there is this kit out there which looks pretty but means changing the diff to a Kyosho - all told that will cost over $200 which I'd rather put to motor and lipos - The esc mount looks sweet though so if mike's watching - I'd but one from you!

Any suggestions on motor / gearing - I'd like to get 40mph out of it - I'm in the debate of cheap (Feigao 8XL) or jumping in with the Neu - Would I need the 1515 or the 1512...

Apreciate all thoughts and input on the conversion - there don't appear to be too many out there...

Thanks!
