I just got a 3.8 and it's not what I thought it would be. After 3 consecutive charges it started getting slow. And torq is very slow. My 2.6 K.I.T motor on a bit from hotwheels beats it on a 4 feet drag race. I just thought I would give some newbes some info before they get a 3.8 motor which only last a few charges. Whats a motor when you can't even use it? So I would recommend a 2.6 or a 3.0 for the newbes.
