novak 10.5ss help please
 

Hey there I have this Novak 10.5ss and when your driving at a slow speed it's fine until you hit the gas it sputters like how a nitro engine kind of does or its sounds like a striped spurt but the car is fine . And it also bottoms out like really slow I'm using the vxl esc and I have the motor connected to the sensor port on the esc. Is it my esc I dont know what it is help me . Please

The vxl doesnt do sensored motors well.
