This is why pan car racing is taking off , the current batteries now have the capacity to provide a 1/12 scale with a 9 turn enough hp for 8 minutes also none of the drivers can go anywhere near full throttle on the back straight. With a 9 turn as it end up going too fast for the corner at the end of the straight. Going fast mean the car has to be prepared perfectly for each run bearing absolutly free diff smooth and free sunpension free etc.
Maybe to go fast on a buget we should look at 1/12th again
