Albert,

First, thanks so much for your input to this forum! Great to know
your out there.

Can you tell me what the 'optimum' pressure the propane/butane mix should be (in psi) for proper, reliable starts.

Also is it possible to have the gas bottle not installed in the aircraft and just disconnected when the start processes is over?
What would you need for this?? Maybe a Festo check valve
between the bottle and the solenoid ? OR does the solenoid
close after fuel ramp?

Thanks
