“Got the quantum r flux , running on 4s 5000mah , I find the speed control lags if you let off throttle and back on its very slow to react ( that might be a setting issue ) I’ve ran 1 full battery through it and it’s going to have to be fully stripped down and replaced the wheel bearings and check the rest of the bearings and replace if necessary , It looks like hpi are cutting the quality of components , overall a reasonably quick truck but has quality issues to price it cheaper, I’d rather they used better components and charge a bit more instead of having to replace bearings after 1 run”
