I would fabricate a fiberglass duct off the baffles, to a short length of 4" SCAT, to a reverse duct (diffuser?) on the front/top of the oil cooler. By doing this you remove the weight of the oil cooler from the baffles, which I personally believe reduces the stress on the baffles immensely. I'm speaking from theory, not experience, so take this with a grain of salt. I also read your previous email about oil cooler types, and I usually recommend the Stewart Warner 8406R oil cooler for any Lycoming variant up to 180hp. It works on a 200hp angle valve engine, but it's on the verge of being slightly too small. Cools absolutely great when LOP, cools tolerably when ROP, doesn't cool so great at slow airspeeds. On a 180hp parallel valve engine, the 8406R should be plenty, assuming you've got a reasonably tight baffle setup or a plenum. Just my 2 cents. )_( Dan RV-7 N714D (651 hours) http://www.rvproject.com ----- Original Message ----- From: "DEAN PSIROPOULOS" Subject: RV-List: Oil cooler baffle beef-up > --> RV-List message posted by: "DEAN PSIROPOULOS" > > > Having read the Checkoway oil cooler saga, his recommendations and looking > at his pictures...I see he has NOT used the flimsy mounting template that > Van's provides.

Rather odd how the advert describes it as made of aluminum and stainless in the long description then says it's made of brass as you read down to the bulleted specifications. It's probably solid brass and steel as mine was. Mine did start leaking so I replaced it with a Fumoto valve that is excellent. http://fumotovalve.com/ Brian Denk RV8 N94BD RV10 '51 ________________________________ Message 4 _____________________________________ Time: 05:21:07 AM PST US From: linn walters Subject: Re: RV-List: Starter not disengaging --> RV-List message posted by: linn walters Why not go to the source?

After you torque down the fitting, the little brass ring is swaged onto the tube and is going nowhere. Just remove the compression nut from the other end and leave the brass ring in place. It does the same job as a beaded end. Ron Schreck Gold Hill Airpark, NC Dwight Frye Wrote: I had a friend with an RV-4 who had a similar problem. He noticed that some safety-wire holding some baffles had started to saw a nice little slot in an oil return line. We fabricated another one (with slightly different routing) and then wanted to put a bead on the end of the tube. There seem to be two choices (three if you decide, as another list member suggested, to simply not worry about it). One is getting one of the really nice Parker-style beading tool sets. They apparently do a beautiful job but are NOT economical for one or two uses. Or, you can do what we did and get an Earls EZ-Beader. See http://www.amstreetrod.com/011ERL.php4 for details. One for the tubing we needed was less than $20 and gave him some extra peace of mind knowing that the bead was on there. The tool is about as simple as it gets ... and does a fairly good job. The bead is a bit "thinner" than what was on the original, but does fulfill the task of making it extremely unlikely that the tubing would slip out of the little rubber hose. Honestly, I don't see how it could slip out anyway given the geometry of the whole setup .... but since there was a bead there originally, we felt best adding one to the new piece of tubing if we could.

Barrie" Subject: Re: RV-List: High Temperature Epoxy (was attaching plenum) --> RV-List message posted by: "Darwin N. Barrie" Don't get too worked up over the temperature issues with epoxy. I have a friend that makes parts for several of the NASCAR teams and he uses West Systems and EZ Poxy. These are standard over the counter products. If they don't have temp issues I don't think we will. Also a plenum has a constant source of air movement. The key is to make sure the epoxy is mixed properly. Good luck. Darwin N.

Prolonged gear engagement due to auto-generation of voltage in the starter is a well-known phenomenon, with a straightforward fix that involves rewiring your starter relay circuit. It's all in the 'Connection book as well. Strangely, even though I have a Sky-Tec and a panel indicator light to tell me if the relay stays engaged, it's never been an issue on my particular ship, even with conventional wiring scheme. Obviously, "mileage varies" with this problem. -Stormy ----- Original Message ----- From: Subject: RV-List: Starter not disengaging > --> RV-List message posted by: HCRV6@comcast.net > > Hey guys, I should have guessed things were going too well.

Both Oil cooler and cabin heat box mounted on right side of firewall. Oil cooler above cabin air box. During the warm 6 months of the year, my exhaust heat muff is removed for lack of use. A 3 inch scat tube feeds cool air to my oil cooler giving me temps in the 190-194F range most of the time with slide on the bottom of the oil cooler closed off 3/4. In the winter, heat muff is hooked back up. Warm bypass air from the heat box flows up past the oil cooler keeping my oil temps again in the 185-190F range most of the winter months. Oil cooler slide is wide open. Seems to work real well on my 0320engine. No undue stress on the baffling. Enjoy your web site by the way. Keep up the good work.

Polyester resin is really susceptible to heat damage. Vinylester is less susceptible than polyester. Most epoxies are pretty resistant to heat, but will still soften with heat. High temperature prepreg is still better, but must be cured in an oven and gets stronger over time with added heat .... like y'all out in the deserts. Darwin has a point .... you'll probably not have heat related problems with a plenum, but when you shut down that engine temp just bakes under the cowl. Hot air will rise up from under the cowl, through cylinder fins, getting hotter, and up into the plenum. That's where the damage could be done. Maybe facing the airplane tail into the wind would force cooling air backwards through the engine compartment and out the intakes. Who knows? Linn do not archive Darwin N.

I'm starting to think it's due to the way I wired it. I'm not using the standard Ray Allen rockers or indicators. I have a coolie hat on my stick, wired to two relays, one for up, one for down. I believe the "delay" inherent in using a relay allows me to make much smaller adjustments with just a flick of the coolie hat. Tap...tap...tap, and I'm there. Anyway, I'm tired of hearing people say that the "electric trim is too fast" or this and that. Qualify that with the details of the system you're using, so we can compare apples to apples. Also, it would be interesting to see how much of this comes down to coordination & quickness of your fingers -- i.e. "operator error." I don't see what the fuss is all about with electric trim. Works for me! In a plane which gains altitude if I bend my knee and descends if I straighten my leg (that's how I hold altitude when cruising, literally) -- of course you're going to have some built-in sensitivity.

I have the older style Ray Allen stick grip (4 separate buttons for trim) and I wired a micro switch to my flap positioning arm. With flaps even slightly down I get full voltage but with them up the voltage is reduced and so is trim speed. I'm thinking about adding another voltage adjusting module because the aileron seem much less sensitive than the elevators. Albert Gardner RV-9A N872RV 605 hrs.

I > don't > see what the fuss is all about with electric trim. Works for me! Granted, my coordination is 63 years old. I tap the rocker switch on my panel with a one millisecond touch. It is just a bit to high and climbing. Another tap in the other direction, it is descending. A bit longer tap in the other direction followed by a short tap in the other. And the beat goes on. > > In a plane which gains altitude if I bend my knee and descends if I > straighten my leg (that's how I hold altitude when cruising, literally) -- > of course you're going to have some built-in sensitivity.

I've researched this for quite a while and I'm stumped. TAP Plastics up here in OR is the epoxy place around here and they only say that a marine vinyl ester resin has slighty more heat resistance than epoxy resin. According to the spec sheet, using ASTM D-648, Vinyl Ester Resin has a Heat Distortion temp rating of 240F. The spec sheet notes that this is a "clear casting" rating. TAP was "not aware" of high temperature epoxy. This may make sense, especially IF THEY DON'T SELL IT. From an empirical standpoint, all the glass plenums people have made here (about 6, including some with several hundred hours) are using epoxy resin, (both those using carbon fiber and regular glass). I don't observe any softening or other degradation on these plenums, so....unless other specific info shows up on this topic, I'm pretty sure I'll go ahead and use (West Systems) epoxy resin to do the carbon fiber plenum...which should be! > soon. > >Bob Brown >RV7A - cowl fitted! > Find someone who has a set of Rutan VariEze plans.

They added an additional brace and beefed up the bracket which the oil cooler mounts to and I am told by one of them that they have had no problems. I carefully examined one of these installations as I am working on my baffles now and carefully duplicating it. The extra brace is a piece of 6061 3/4"x 3/4" angle about a foot long that goes from a tapped hole on the left side of the engine which is at the top of the case between cyls 1 and 3, to the inboard flange of baffle part #5. That's the one that the oil cooler is mounted to. Baffle 5 is not well constrained against motion in the forward-aft direction and this brace fixes that. Part of the angle has to be cut away to get around the push rod tube of cyl #3. I have a photo of the brace, if any one is interested. They also beefed up the bracket that the oil cooler mounts to. Van's drawing shows a little "picture frame" sort of thing. The Tucson version is nearly as large as the entire baffle #5 itself. It has a flanges on all 4 sides to stiffen it. The outboard, top and bottom flanges are made by bending the edge of the plate 90 deg. so that it extends aft. The flange on the inboard side extends forward and wraps around the flange of baffle 5 where it overlays the flange of baffle 6. It's about an inch long. All these planes use the SW 8406R cooler. It's expensive, but I think it's worth it. It gets hot in Tucson. -- Tom Sargent, RV-6A, engine
