Like I said, if it were me, I would run a MM for sure. It might be overkill, but alot of us have them laying around so why not?

The size is small and the have more adjustment than needed, and there not to expensive either, which is perfect for a 1/16th. Why drop a ton on a 1/16th scale? Doesn't make to much sense. Unless you can get a Neu cheap, I don't think i would run it after thinking about it. I'd take my chances and run one of the Hacker knockoffs from BidProduct. They have a 2858 that should be more than enough for a mini Revo and you have more kv options than the Castle 26mm motors.
