mm vs mmm v2

[auto2]

even my 1512 is more than u can even think of using at the track. flip over backwords on the street, pull the front end up half way down the straight on the track. that is why i had to regear it. easy to calabrate too.
Oh and BTW the fans turn on during start up so you can check if it is working every time u turn it on.
The old issue of heat VS top speed is no longer an issue. put any pinion in it you dare.LOL!
