You can fly all you want at a NON-sanctioned AMA field to your hearts content, but if you kill someone with your plane or damage property then YOU will be held liable. If you fly at an AMA SANCTIONED field without a turbine waiver then I suspect that you will be banned from that facility indefinitely, because if you crash their then they will be at fault and not covered for your negligence. Pretty straight forward.
Unfortunately, you are wrong - at least according to Carl Maroney, Ilona Maine, and numerous other AMA officials that I have had discussions with on this topic. Why don't you phone Carl and have a chat with him about ignoring the AMA rules just because you are not at an AMA chartered club site ? Just to make it interesting, tell him you intend flying a 100 lb turbine powered model at 300 mph, but that the AMA need worry because you are going to do it in the middle of the Mojave dessert.
Let us know how you get on...
