Contact you have got to be joking. If you can show me that your total laps times are just a quick in stock if you ran 8 min than they are in 5 I will give up racing. Sure you can run for 8 mins both stock and mod but your lap times are going to be down to make run time. I use now a 8 turn motor for mod some people run 7. You can't tell me that we can't gear these things harder to go quicker if we had no run time issues.
I have to agree with besercoe again. You don't see a race series with cars going around at 80% pace because they are trying to make race distance on fuel.
As far as Brushless motors are concerned, I can't see any down falls in this move apart from shops and manufactures loosing a area of their business that makes a lot of money.
