Thanks for your responses. I'm currently running a brand new LiPo battery and have tried a few older ones with the same result. I don't have access to another sensored ESC or motor so I can't swap it individual parts, but I do have the stock Reedy 3300KV and SC450-BL ESC that I think my friend pulled out when the truck was brand new. At least they both look like they've never seen dirt. I may mess around with the Reedy this weekend or just go into the hobby shop and see if they can help me troubleshoot the Novak.
