I know your club, and the rules there are excessively restrictive for gas engines. Fueled turbines and electrics are the primary generators of crash fires.

What makes gasoline less flammable/volatile is the 2 stroke oil added to the gas. It reduces the octane rating several points and stabilizes the gas. The odds of a gas powered plane catching a fire in a crash are not much higher than a glow engine catching fire. Essentially one needs to short out a battery lead and have fuel pouring over it. I've even seen such conditions occur without generating a fire.

Basically you have a bunch of old women that didn't like gas powered planes to begin with setting the safety rules. The brush out there is high and dry in the summer time but their resistance to change is even higher. Don't know what you're going to be able to do about that aside from electing new officers and voting on new rules.
