Mamba monster cogging

[jackson020]

I have a converted Cen GST with a Mamba Monster ESC and am having a cogging issue.If the truck is stopped,it will not move unless I give it a tap with my foot.I dont have to move it hard,just a little tap does the trick.Once the truck starts though it goes like crazy.It has a ton of tourqe and runs about 35 mph.I am confused here.I thought if the gearing was so bad that I had to kick it to get it moving that there would be no tourqe.This truck wants to tear the rims right off of it.I am using a KB45-XL 700 KV motor,Mamba monster ESC,5s 20c Zippy lipo.I have a 66t spur gear and a 18t pinion.It has alot of tourqe and nothing seems to be getting hot.The battery gets slightly warm and that is it.Any suggestions?Thanks
