    Some ESC's have a minimum throttle setting that can cause that feeling. Or you could be running in sensorless mode due to a bad sensor cable or something.

    I think that is largely dependent on age and upkeep. The fuzz has to be vacuumed or traction will suffer. As black carpet ages, the grip falls off rapidly.

    Yes, it appears that the more sauce that is used, the faster the carpet goes to crap.

    Yup, that is why I use storage voltage. It is quick and easy to do and the voltage is much more stable. If without seeing curves, most people are familiar with the extra punch they have in the...

    Yup, I agree that the Schumacher tires are very consistent and they last longer too. Unfortunately, they are just a bit slower than the Fuzzbites. I regularly use cut staggers and cactus tires for...

    Both of those ideas will drive entries out the door and therefore it is unlikely that a track owner will do it. Even if you do make the rule, you still have to enforce it which is a lot of work for...

    For my limited testing, I used regular clay tires with closed cell clay foams in both the front and back tires.

    I played around with some clay slicks at the carpet track this weekend. They work but they are about 10% slower in comparison to carpet tires. They are also significantly heavier and taller. I...

    It will be interesting to see if the slick tires actually help. Pin tires reach beyond the nap of the carpet to get traction. Slicks try to stick to the nap which puts more stress on pulling the...
