Hey, What's up guys and girls. I just recieved my 180 mini mod motor and 13t pinion. Wow , this thing flies!!! There is such a big difference. I have two DRR's , honda NSX (grey)and McLaren(red) Side by side, there is no comparison. I was wondering what the rpm is for this motor (i would like to know how many mph it's going. I also hooked up a temporary 7.2v system to see if it made a difference, Holy Cow!!!!! I was on a new driveway that someone just put down a few days ago,it was about 110-120 ft long, I COULDN'T EVEN GET IT TO WIDE OPEN FULL !!! before I had to ease off so as not to run into fence. Any help finding the rpm would be great.

p.s. I'll post how I hooked up the 7.2v later,
