I have to say that my experience with the system has shown it is not as effective as you might imagine. The problem is that it works fine in the climb when the temperatures are up, but in the cruise, my 914 will cool right down and then the heater is ineffective. The cooling system on G-JULZ is just too effective in the cruise and it concerns me that the engine is running for lengthy periods at temperatures well below 100degC. I have a modification in progress to introduce a cowl flap in the cooling air exit in an effort to control the engine temperatures. If it is effective I am also developing a micro-processor temperature control system to make the whole system automatic. If this mod works then, the heater will hopefully become more efficient.

To any interested builders out there. I have a 7 function Mac stick top, Navaid Wing Leveller Control head, Smart Coupler( for Skymap 3C) and DG Coupler available. Used but fully serviceable, any reasonable offer accepted. Regards, Mike ________________________________ Message 3 _____________________________________ Time: 11:16:35 AM PST US From: "ALAN YERLY" Subject: Re: Europa-List: RE: Heaters I use an expensive and fully lockable cable which holds the flapper shut because I fear the same problem. That shuts off the fire inlet at the duct. I draw the air from a low risk fire area, but not a perfect solution. If I had regs requiring a stop valve, I would make it from stainless as a box with a flapper in it. Aircraft Spruce has a heater valve which I would use as a guide. Theirs is made of aluminum. Let's face it, if the aluminum melts because of a fire, you're in serious do do.

That is taking the warm air off the rear of the water radiator. Mine is fitted but not operational (fire wall phenolic is bolted over the outlets of the SCAT tubes) The reason for this is that Francis Donaldson (LAA) insists on a fire stop valve at the point were the tube passes through the fire wall. One builder, Mike Parkin, has made up some very expensive petal valves to achieve this. See attached. I am still looking for a cheaper and simpler solution to these valves. Obviously US regulation is not the same as ours. What are your thoughts on a) the need for fire stop valves and b) a simpler cheaper way of achieving a fire stop?

The cockpit module is heavy and requires a lot of help to get it in right and it is very time consuming to build for the novice, and for the company to construct. Keep the ideas coming. Go to my website and download the heater. One inch tubes is all you need really to keep the plane warm.
