This thread is stupid racing classes get faster every year. If the cars are to fast race in the vta, or silver can class. The tekin esc are $180.00-$220 compared to 400 for the black diamond esc. You also get free software updates to make them faster were you have to buy lrp and novak esc every month. You will never be able to slow down the race cars. If you take something away they will find another way around it. Just like in f1 racing they tried to slow the cars down beacuse they said that they were getting to fast so the cars run 2.4 liter v8 engines producing 730hp-750hp 18000rpms compared to 930hp-970-hp 22000rpms produced by the 3.0 liter v10 engines. And guess what they have found a way to run the same laptimes that they were running when they had more power. It is a fact of racing every year the Rc cars get faster electric and nitro. If you can't keep up get out of it and find a class that you can keep up with.
