"When it comes to brushless there is somthing to be said about, the car never changing its power output during a race. I drove better because I didn't have to think about the motor or how much power its got. the brushless never changes
25% less energy loss for the same power of a brushed motor sounds good to me. its way nicer on the batteries
stop messsing with motors and batts and drive the car!!
And yes, you could feasibly get the GTB as slow as you want, just limit the EPA(End Point Adjustment) on your transmitter.
I'm very impressed with mine so far, and as soon as our track is ready, I'll have comparison lap times(vs 19T chameleons) and a trap speed, along with gearing experiments to see where it needs to be...
To be honest, I don't expect my lap times to be alot better, considering the difference in fastest lap between the nitro class and the 19T class wasn't very big. It's true, the electric cars handle better, so they got through the twisties quicker(wich at our particular track is where the race is won). Only in 2 portions of the track will the additional power really make a difference, here are pics so you can see why:
