Motor problem

[LosiKid]

Hi, I just got an LRP 6.5 motor for my B44.1 running a speed passions reventon pro ESC. The problem is that the motor coggs a lot when you put full power on the car form a stand still but also after 15 seconds the car will start to drive very slowly. I did change the battires but still have the same problem. I never had this issue with my speed passions 7.5 motor. but it's fixed when I run no timing or punch. is there a way to fix this problem so I can run some timing and punch?



Thanks
