I have an airstart turbine that reaches idle in about 15 - 25 seconds after propane lights up, and to me that's a looong time, what turbine model are you talking about? Model turbines only use propane to heat up the combustion chamber because they have no actual fuel vaporizers, not for thrust generation or chamber pressure or anything on that line, can't see how you intend to REDUCE start-up time by replacing propane with some other fuels on a kerosene burning engine, can you explain?
