Hyper 9e on 6s

[jalodo56]

Hi, today I run first time my hyper 9e, the setup is a neu 1515 3d on mmm with 6s lipo gear for 38mph, it have too much acelerate, I thinck that the car is undergearing, the motor go to 176 f!!!!! and the esc and batt was cool, I am going to gear it to 48mph (I don't have another big pinion) but it is too for my track, I want to limit the speed whit my dx3s, I think that it is going to run cooler and it will have more runtime, what do you think about it?
