anyways after reading though some 250 pages so far i liek these to motor http://www3.towerhobbies.com/cgi-bin...9&I=LXAETU&P=K this one i belive would be the best one for power and im hopping low heat but have to work it in the car or dremmel a little from what i read http://www3.towerhobbies.com/cgi-bin...&I=LXBLCE&P=SM or i got this one that will drop right in any one try them both im kinda looking to do the 3 pay so i can get some tires and a sway bar set fast also so it got to be one off these motor here. I have one more question what is better seneorless or senored one that would be a big help since i am a nitro guy and looking to get an electric. i will be running on a large out door track and we have some huge sucide jumps this will need to clear and the stock 17.5 turn motor just do cut it at my track they ant fast enough for the jumps lol so im assuming this is the right direction to be going with is the 1415 motor the 2400kv and i hopping that kv number is good since no one explained what kv is best yet or if it should be high or low
