Did you originally run this setup on a nimh battery? I think the problem lies with using nimh batteries at all. My theory is it does something to either the motor or esc. Luckily I got my LHS to finally let me exchange this and went with the velineon which I have had 0 problems with. If I was you I'd try to get wehre you bought it from to exchange it. Venom needs to fix their ****. The guy at CS kept arguing with me that you have to use a lipo only. They should probably put that crap on the box then instead of saying what nimh batteries it is compatible with. I will never in my life by from venom again. I'd also highly discourage anyone else from using any of their products. Me and you are not the only two people that have had this problem. If you go through their customer service you will have to send your stuff to them and wait for them to fix or replace it. If thats the route you are forced to go I'd put it up on craigslist or ebay or whatever and go with the vxl system. That or pick up something from hobbywing.
