Jesus!!! And I though my 1521 1y on 6s would be a bit much... The tires must have been 8" diamter minimum at those speeds...

Just for comparision I run a 1515 1.5d in my erevo on 4s lipo geared 19/50. It does over 40mph and never breaks a sweat. It does work a pair of trakpowers pretty good though... I have a pair of fp 4s 3700 packs that I plan to run in parallel, that should provide plenty of juice.

yea, a 1515 1.5d on 6s is a bit much...ESPECIALLY AT THAT GEARING!

I run the 1515 1.5d on 4s with 24/62 is goign 45+...

and are your batteries the 15c zippy? sounds like they are COOOOKING

HA...this from a guy who opens his beer bottles with his MMM


she handles like a dream though....flew over the speed bump like a bird and landed like the space shuttle

I'm going to blame it on Larrydino over at traxxas....I was trying to win the $20 for the first guy to hit 70 with the mmm...not really for the money...for bragging rights mostley

anyway ya I wont be trying that again

Till i saw the inside of the case, I was wondering and still wondering. The bold and underlined part makes me wonder, whats the theorettical RPM of the mamba monster on 2 pole motors? The RPM shown would be 117,328 RPM's as seen by the esc due to being on a 4 pole Neu. I am wondering what the RPM or phase shifts the esc can handle. I hope thats understandable
