I have a nightcrawler also I'm really liking it now. When I first got it I was not impressed. No I'm running a z650 servo. Still kinda light duty if you do comps. And a vxl esc and a fuze 3300 motor. Soon I will change out the vxl for a castle sv2 with a bec and it will be even better. To answer the question I hear coming. No cogging.
