Bill,

Thanks for your reply on this issue. It would benefit everyone on this list if you would share your data on the oil cooler. How m uch temps decrease? How was the testing conducted? Temps? Humidity ? aircraft? hours tested? etc. What is significant temp reduction? Most posts on this list are anedotal responses based on limited p ersonal experience or that of a few friends. Hearing your professi onal experience and the extensive testing procedures of this issue would be of value. Just like discussions on PROP performance it is hard to replicate a CREDIBLE test or side by side tests, so please share you r details to assist all us builders deciding what we can do to improve o ur aircraft.

I also sealed up all of the large gaps in my baffles.

I also fabricated the little air dam that goes between the air valves, and put some baffle material between the air valve seats and the firewall. With this, and the latest version of the exhaust system design that comes with Vans FWF kit (two pipes, longer length than earlier exhaust designs), there is virtually no tunnel heat problem in my RV-10. In fact, cruising along at 9.5K on the way back from OSH, the tunnel was quite chilly with the outside air temp at about 55F. (But lots of heat was available on demand from both front and rear vents). So it may be that with evolutionary changes to the kit, particularly the FWF exhaust system, the tunnel heat problem is history. (My kit was 40448 and I got the FWF kit about December of last year). -Dan Masys N104LD flying 33 hrs. ---- Tim Olson wrote: > > You could get rid of it and try it, but, I think you're going to want > something on the firewall anyway, be it Kool Mat or other, so I'd > say just leave it and see what you think after you fly. it's nice just > to prevent some sound resonance. > > Tim Olson - RV-10 N104CD - Flying > do not archive > > > The McGough Family wrote: > > Guys that are flying I installed a Kool mat on the firewall due do > > complaints of tunnel heat.

Tim,

I've been using the AFS White Primer for the entire project. I think it's at least as durable as the Sherwin Williams Wash Primer or the rattle can stuff. Easy to clean afterward.

It can be diluted with water, but be careful to only apply a light "fog" initially to the parts. After that, it adheres to the parts without running as easily. Dry time is good too.

Just as an experiment, I applied some of the AFS 2 Part High Gloss Paint to the interior rear foot wells early into the fuselage construction. After much traffic and the occasional dropped bucking bar and other things, it seems to be holding up well. Gloss is as advertised. I can't speak to the comparisson to other brands.....no other experience.

Limited information to your specific question....hope it helps.

________________________________ Message 19 ____________________________________ Time: 07:14:06 PM PST US From: Deems Davis Subject: Re: RV10-List: Windshield Installation Cal, I also had a problem with the windscreen bowing outward from the cabin frame. here's a link to a picture of what I did. http://deemsrv10.com/album/Sec%2045%20Cabin%20Doors%20and%20Transparancies/slides/DSC04376.html Basically I used some clamps, some clecos and some scrap .062 alum 'fingers' to hold it in place. As to the Gap on the bottom of the windscreen, I'm not sure that it's too critical, as the windscreen is held in place primarily by the fiberglass layups that lay over this and the upper fwd fuse. You will fill the gap with flox, and obvioudly the smaller the gap the les there is that will seep inside and need to be cleaned/removed.
