Your going to have to do some research around the forum! Its a Sensorless motor which means a completley different gear than what we're accustomed to! It also might be tooooooo much motor for a 2wd vehicle on dirt. The Sensorless motors are dead out of the hole then like a light switch because of their extremley high RPM's!

I think Ed tried to run the Castle 4400KV Sensorless motor in his 4wd(?) buggy and took it out because it was to much for the car and the track.

If you have not purchased it yet I'd look at getting something with a Sensored design maybe in the 6.5-8.5 range that would be more "controlable" for the track. Maybe one of these:http://www.amainhobbies.com/product_...less-Motor-65T

Or if your set on going with the Losi brand:http://www.amainhobbies.com/product_...otor-Combo-35T this is a SENSORED set-up.
