Jetflyer 24

If I can add my support to Mr Matt. I have been using neat propane for about 2 years. Certain engines, in particular the Artes range, start noticably better. The Jetcat is a dodle. It is not affected by cold weather. It is wonderfully reliable and much less expensive.

However it is not for on board enthusiasts. I have always used a quick release going directly to the auto control valve followed by a non return (festo valve) in the model and a standard propane reduction valve followed by a Festo needle valve followed by the the other end of the quick release on a standard 5Kg propane bottle with screw valve. I find i/2 to 3/4 of a turn quite enough! I have read the pressures may be in the in order of 20bar or 250-300psi for liquid propane in warm weather compared with 70-80psi for the butane mix recommended. That is why neat propane comes in big heavy steel canisters. I once had a bird scarer explode and it cinderised the green crop for about 3 yards in every direction (fortunately no one was around). Since then I have had a profound respect for the stuff! If you want to cinderise yourself and your model - use a low pressure sytem on high pressure gas.
