I finally got around to installing mine this week in my Slash 4x4.

I had to re solder some 4mm bullets to the MMP, I sold the Sidewinder ESC at the track Saturday, so I never ran it with that ESC.

I started off with the gearing at 15/54
Start Power Medium
High timing
100% max fwd

Turnigy 5200mah, 30c 2s

WOW!!
This thing rips!
Way more balls off the bottom than the Velineon with the same gearing and ESC settings, had no trouble pulling the wheels up from dead stops or a slow roll...
ran about 15-20 minutes on the street in front of my house, few trips through mine and the neighbors yard chasing curious cats.
Motor temps at 119 and esc at 109, ambient temps around 70's

So...
I took it back to the lab, threw my 19t pinion in it, jacked the timing up to highest, and start power to high,
grabbed a fresh battery ( same specs) and then zip tied my GPS to it for a speed run.

These are the same specs I used with a 3200mah 3s battery to get 61.9 before on my Velineon, this setup on a 2s I got 49.8!

I cant wait to get the Deans connector soldered on my 3s, I used to use TRX connectors on everything, im in the process of getting all my batts switched over.

I think i'll break 70 with the 3s,
I wont get to run it on the track this weekend, as I have to work, but I should be able to get it out there sometime next week.

Bottom line, go buy one!
Throw the Velineon setup on eBay and buy this already!
