God people, it IS how you drive, you are not supposed to jam on and off witht he brushless because that will wear that area out an other VERY quickly also your belts will not last as long, the sprint2sport is actually NOT a racing car at all, or they would of called it the sprint2race....the sprint2sport is for recreational driving if you want a good car for touring look into some other cars they offer, as for your problem, HPI cas great customer support and it actually is your fault you jam on and off, you should keep the throttle low or set your radio settings so that the car has a somewhat high constant, if you are racing this should be no problem. The car was not originally designed for brushless but it will work if you know how to drive, this car is really not for racing though, at least if you don't know how to drive it, the TT-01 isn't an actual "Race" car its more sport...just like the Sprint2Sport.

The only reason there is a drift version is because its set up nicely and drifting, while it does stress out other parts of the cars chassis and such, does not stress other areas that are weaker. You just need to learn how to drive the car before you go complaining to HPI about how bad their car is.
