I ran the Tekno RC conversion, 4s 16c Hyperion 5350mah battery, MM with Castle BEC. The Medusa's are good motors, the only negative i have to say about them is I have had the endbell pop off on me. Not that big of a deal, the older version of the Neus were subject to that too. I just put it back on and ran a bead of CA around it, no more problems.
What do you all think of the gearing change in doing a Revo 2.5 -> Slayer conversion? To do it right would require new tranny case and gears as Traxxas changed the gear ratio to accomodate the shorter tires.
Would it be possible to stay with the Revo tranny and gear the spur/pinion accordingly?
