I run a 2wd Slash right now and I am looking to try 4wd. I have a kit on order and I am looking at motors. If I understand things right, a lower KV gives more torque but less top speed. Given I am a total novice, would a (SC4X?) 550 7.5 be the best bet? I only want 3 things: 1) To learn to run some clean laps! 2) To keep temps on the motor and ESC low enough so I don't have to obsess over them, 3) Have enough "grunt" to clear a few obstacles.

Thanks!

The outer lane is a dirt oval and not really part of the off-road track.
