The motor looks great and I like 5 port motors but I am going to wait to see if the fuel milage is in the 10's like you say. I was watching the Live RC Fuel Nationals broadcast and when they interviewed Kortz he said he can just get 9 so that means he has to pit at 8 and Drake was going over 12 with the +4 and that is one less pit than Kortz at the Australia race. I know his +4 is not stock but I see them go 10+ all the time. If this new 5 port will go 10+ I will get one because Werks has always been good to me.
