Also the Iron Bay regulator will hold up fine for glow fuel. It was designed for Ducted Fan engines originally. Yes, over a LONG period of time the diaphragm will dry out with glow fuel. This takes years, and Iron Bay will replace the diaphragms for free for as long as you own the regulator. The regulator continues to work fine though even if the diaphragm dries out. As long as it isn't cracked or broken which wont happen unless it is totally dried out and you take the regulator apart. Some of the original regulators I've seen have been running on glow fuel for 3 years now without any problems with hundreds if not thousands of flights.
