My rc18t with Hacker E30L motor and Quark 33a controller is exhibiting a cogging at very low acceleration (only from a dead stop). It basically "stutters" as it takes off. I am running 7.2v 1200 mah NIMH batteries. No desire to go to Lipo at this time. Before I go into my programming on the controller, would setting the Nicd/Nimh low battery selection help? I know this has to do with how much power your battery can put out initially. It's set to high, right now.
