That's what I thought too. Not so fast grasshopper.
One more thing If the fastest guy here ran a 20 dallor traxxes motor he would get smoked. Here you have to claw for every tenth there are many drivers that have consistency during a race from there fastest lap to their slowest lap have a half second spread. Even me with meger skills have a .8 of second deviation in laps from fastest lap to the slowest lap puts me 5 seconds back from the lead. Most of my laps are in 3 tenth range on a good day. I run third or fourth most racedays.
I have also seen almost every brand of motor win a race every brush less motor is different and some are just put together and magic happens. You can buy a $99 middle or $150 boat anchor. Some guys really know how to gear and time a motor for peak performance. I think that is more important than brand or costs.
