I have no doubt that a turbine could run on gasoline - or most any flammable liquid, if it were tuned to do so. How well it would do so and how efficient it would be is another question.

The real problem I have though in the models is that I almost always get some fuel in/around the model besides inside the fuel tank, despite how careful I am. In addition, I quite often get externally visible flames from the tail pipe when starting my JetCat. With gasoline, those two factors spell barbecue. In addition, after an aborted start that occurs because the gas tank is not fully charged or the glow plug is bad, the next start attempt could result in a real "bang!"
