Default Novak Brushless Cogging

I recently bought a new Novak 10.5 motor that I run with a month old GTB. While exiting the corners at the track, the motor coggs(or sputters) coming out of the corner a little before clearing out and then runs fine until the next corner. This has also happened to me with a different 5.5r GTB system that I also run in another car. I run a T4 with a JR XS3 radio. Any help would be greatly apperciated. Thanks, Doug Yunker

Yeah, it definitly could be the gearing. I have an 87/23 right now. Next week I'll try a 81 or 84 spur. I do run the capacitor on the GTB.

If it's cogging and your already running an 87 spur, going to an 81 or 84 spur would be going in the wrong direction to stop the cogging issue. Gear it lower to stop the cogging, not higher. Try a lower tooth count on your pinion. Start at a 20t and test again.

I experienced Cogging with un sensored motors, not with a GTB.
