Todays better .28's keep up with electrics fine and weigh less. Nitros still win when we combine the classes. The only disadvantage is at the start, if an electric is right behind you, expect them to fly right by.
If your races are only 7min for the lame electrics, then run some power!
What we need is a larger fuel tank so we can cheat and run .28's maxed out. Right now 1 fuel stop for the nitros is about equal to the electric guys haveing to slow down a little in the middle of an 11min race to make the time. If you set your main times to something wonky it can swing in one type of cars favor.
