I have tried a new stock motor with the same rollout and packs are also new but can seem to get the same speed as before (top end and acceleration). I have also tried resetting the speedo a number of times. Cars drivetrain is free as. Any help?
Not sure if you had this problem all the time with the QC2, or the problem showed up after chaning motor / battery or another change. Check these things:
1: GP packs need to be run in, that is it's first after 3-4 runs, they become punchy.
2: Just one bad soldering can be enough to cause what you describe... I've tried it
3: Motor condition.
