Remember that others might not be outmotoring you, but could be driving smoother as well, or have better car setups. I have not been driving indoor carpet for very long, but have realized that keeping your momentum is just as important as having decent motors and batteries. If you need to let off for every turn on the layout, then you will probably be slow. Someone else that is holding their speed through a smooth line will appear to have a faster motor, when in reality that may not be the case. It might help to fiddle around with setups more.
