Well it seems that the two most poular motors of choice on RCM are the 1515/1y or the 1521/1y depending on how fast you want to go. There have also been a slim few that have gone all out and gotten the 1527/1y, but resolve to the fact that it is just toooooo much power
for Revo scale trucks for good handling purposes.
If you want to race with the nitros and use the MMM you may want to go with the 1521 and gear accordingly. Batteires can always be reconfigured to sute your satisfaction. Good luck with that.
