Awesome news... Maybe if no one else is using the Moden fuel, Cyclone is the only engine that can?!?!?! Woooohoooo. That would be cool. Of course, it must be something diabolical right? Thanks for digging dude. Since you are so concerned about this fuel you should call Cyclone and see what the deal is.
