That is exactly why I said " properly matched to the esc" . When you get the correct radio setting, drive frequency, gearing, timing , and lower the car's rotational mass a bit (under 58grams Without tires, 48grams on the tc4.2 ), then it's over for the non fantom competitors....
You will know you have reached the optimum settings when your motor sounds like a Honda engine when the Vtech kicks in : do not go too far in the gearing after that, instead look for innovative ways to reduce your car's rotational mass(aluminum/plastic, etc,)...
