I'm having some trouble with my first turbine and have three unsuccessfull starts to date. Wren44 w/ onboard starter. I'm running straight propane and was told that could be part of the problem. Another is the great northern gas regulator, the settings don't seem to change anything. It's taking forever to get the gas lit and after I do almost a minute to get up to 100 degrees for fuel ramp. One time with quite a flame up because the ecu dumped in fuel and I failed to react quick enough with the starter. All the time the starter battery has to run is taking it's toll. Outside temp. was not an issue as it was fairly warm out,about 57 F. What gasses are being used and how can you reliably set the pressure? I'm not putting thie turbine anywhere near an airframe at this point. I have a small regulator at work that I will try to fit to a butane refill that I have for my solder gun. Please I don't want to go back to ducted fans!!! Doug
