The 1st is all aluminum, no good in a fire. The second is an aluminum box with a stainless steel flapper valve which should keep fire out of the cockpit except for the fact that the aluminum will melt or deform allowing the flapper valve to fall away from the 2 +" hole in the firewall creating a flame thrower. There is a 3rd. alternative, an all stainless box and flapper valve which I purchased from EPM.AV Corp. http://www.epm-avcorp.com/ I have received my heat box and it is first class. Very well made and cost $96 which is only $23 or $33 more than the one's that Vans sells. but according to EPM.AV's web site the stainless one will stand up to a 2000 degree fire. a blurb from their web site "With an all stainless heat selector box design now in hand, our attention turned to testing the unit in a simulated "real life" application. Paul built a mockup firewall and attached it to a stainless steel heat selector box and proceeded to apply flames from a propane weed burner affectionately named "Puff the Magic Dragon". "Puff" spits out 2 ft. flames in the neighborhood of 1800 to 2000F. Immediately the temperature sensor output signal in the firewall mockup raced past 500F. Within two minutes the firewall temperature was over 1000 degrees and the heat selector box began glowing dull red. In about three minutes the firewall temperature stabilized just below 1400 degrees and the selector box was glowing bright red. Some surface scaling was present but the unit did not melt. After ten minutes "Puff" was extinguished. The stainless selector box held up well as expected. What happened next caught our attention! We attached an all aluminum heat selector box to the mockup firewall and reproduced the same flame test. Within eight seconds of flame impacting the aluminum selector box the frame changed shape and lost substantial strength. The firewall temperature at this point was approximately 400F. Within sixteen seconds, the "flapper" valve melted, allowing test flames to enter the test cockpit area. Within one minute the selector box melted away, with only the mounting bolts remaining. The dramatic and rapid meltdown of the aluminum box inspired concerns about the time available to shut down engine operation and cut off fuel flow." They also sell stainless fire wall penetrations that you can check out as wiring holes can be a deadly source of a cabin fire in an engine fire situation Dan Checkoway wrote: >--> RV-List message posted by: "Dan Checkoway" > > > >>I wonder if you've considered a way to keep flame and gases from >>penetrating the firewall at your wire and cable pass throughs?

I hate to sound like a spoil sport and may be totally off base in this discussion; but, I've just got to ask the question, anyway. Have any of you ever given any thoughts about what the cowl is made of? I think the heat selector box is going to be the last thing I'll worry about if a fire in the engine compartment is hot enough to melt the box. That cowl is going to be going up in smoke. Right behind it will be a canopy melting in my lap. I'm not going to be worried about a fire in a two inch hole. I'm going to worry about how to get away from that melting plastic! One guy has already experienced this problem and didn't make it. He was a great RV-list contributor, too. Of course, I've been known to be wrong about these things and try to learn from my mistakes. :-) Jim Sears in KY RV-6A N198JS (Scooter) EAA Technical Counselor ________________________________ Message 8 _____________________________________ Time: 12:08:32 PM PST US From: "Jerry Isler" Subject: RV-List: Alternate Air Source on RV4 --> RV-List message posted by: "Jerry Isler" I have a filtered air box from Van's that I am installing on an RV-4 and I also have a carb heat muff from Robbins. The question is how do you connect the two together? The filtered air box, as designed, has a flapper valve that opens or closes a 'D' shaped hole in the top of the box for the alternate air source. This source is the heated air that comes past the cylinders underneath the engine. I do not see a good way to connect a 2" SCAT hose to the top of the box and over to the heat muff. The problem is the way the actuator arm is installed on the flapper valve. It protrudes through the 'D' shaped hole so you cannot cover it up with a hose connector. Is the heated air from the cylinders all I need for carb heat? Thanks, Jerry Isler RV-4 N455J Donalsonville, Ga. ________________________________ Message 9 _____________________________________ Time: 12:37:55 PM PST US From: Michael McGee Subject: Re: RV-List: Strobe regs question --> RV-List message posted by: Michael McGee At 10:43 2004-07-31, you wrote: >--> RV-List message posted by: Paul M Parashak > >With all the discussion of strobes, I started digging into the regs and have >a question.

Do I need the combo? > >Regards, Paul >rv8a.parashak.net Simply put, you need to be able to see at least one of the strobes all the way around the plane, all 360 degrees. So... If you use the combo lights that stick out the end of the wing tips that you can see from behind the plane, you don't need the tail light on the rudder. If you use the lights that are recessed into the forward corner of the wing tip that you cannot see from behind the plane, then you need the tail light.

It has a 2" flange for SCAT tubing on one end and the other end rivets to your airbox. The airbox end is raised slightly off of the airbox, and I can think of a couple of reasons for that, but I dunno if they are the *real* reasons. There are a couple of pic's at this link: http://home.hiwaay.net/~sbuc/journal/engine4.html but they don't give a tremendous view of the details of the adapter. ----- Original Message ----- From: "Jerry Isler" Subject: RV-List: Alternate Air Source on RV4 > --> RV-List message posted by: "Jerry Isler" > > I have a filtered air box from Van's that I am installing on an RV-4 and I > also have a carb heat muff from Robbins.

The air flow through the cowling is from the air intake , through the baffles , then down past the firewall and out through the exit at the rear of the cowl. The cowling , at least at the air intake will be experiencing relatively cool air vs. the temp of the air where the gasoline fire is burning. Shutting off the fuel pump and fuel valve could stop the fire before it spread to the fiberglass cowliing.
