i was never stating that nitro was simple, i know it is not. nitro is highly corrosive if not purged OFTEN. it can destroy fuel lines fairly easily, loves to rust pistons, and burns HOT to say the least. that and 20% is going for around 40$ a gallon last time i purchased it.. i was never saying it would be easy to run nitro in a quad, hell its not even easy to run it in the RC cars specifically designed for it. the way i see it though, if challenges were easy, would they still be called a challenge?
