I own 2 nemisis motors a 7xl and a 9xl and I can say for sure that they are the best most awesome motors in the world...If your looking for something to fry an egg on! They also work fantastic as paperweights. Mike is putting the finishing touches on my inferno gt conversion mgm224/flightpower 5s/nue 1515 2.5df/ 2 speed tranny and mech brakes. Mike claims everything will run cool as a cucumber and have savage exceleration all the way to 50mph.
