Dennis, we are looking into this now. You say Rotax is 93 at 50:1, but TAG USA says 98 octane for all, castor oil, at manufacturer spec. Whether we spec the exact fuel and oil and ratio for the class and/or participant; or if we just say that TAGs can run 93 or 98 with RS7 or RC3, having only to declare what you are running, including ratio. Either way we will be able to successfully tech the fuel. We just have to look at the rules and make sure we satisfy the TAG USA agreement. Since the RMax Challenge specs a different fuel, I sure hope we will be able to allow for that. This will be settled sooner not later. We aren’t going to leave anything to argue about at the first race!
Thanks for the input.
