Default instant stuttering

Car started to stutter when I pull the throttle. Fresh battery, it's not over heating, because its the first time of the day that I went to play with it. Been doing it for some time and can't figure it out. Running Ni-Mh batteries with about 30 runs on it. Brand new batteries in the transmitter also. No loose wires. Stock hpi sprint flux 2

The Flux uses a sensorless motor. These can stutter, more so if the battery voltage dips under load. NiMH batteries are less capable of dealing with high currents compared to LiPo.

Double check that the battery is fully charged - it will be warm to the touch when it finishes peak charging, NiMHs are prone to false peaks. If the battery is fully charged, then it is likely to be the case that the battery isn't up to the demands you are making of it. A LiPo upgrade would be worthwhile.

It's the first model of the sprint flux 2. And it just started doing it for a week now. They are pretty much new batteries.
