Subject: Oversized Oil Cooler Installation For IO-390...
Since the IO-390's a little bigger than the 0-320's and 0-360's traditionally used on the RVs, there have been reports of issues with oil temperatures climbing too high. Marc Ausman has some very interesting findings on his web site http://www.io-390.com regarding his experiences with the IO-390, his RV-7, and some various oil cooler installations he tried. Essentially, it boiled down to using a Steward Warner 10610R oil cooler to keep oil temperatures in a normal range. The problem with the 10610R, however, is that it is a LOT bigger than the stock Van's oil cooler. Mark had trouble fitting it on his RV-7 and I've got even less space on the RV-8. So, once again, I found myself having the re-engineer to accommodate the IO-390 engine installation. The rear left baffle with the Van's supplied .040" doubler is sufficiently rigid for the stock oil cooler, but the SW10610R is quite a bit heavier and also about 1.5 times as wide. Initial fittings looked like it was going to be a close fit if it would fit at all. I spent the good part of two full days working on a new design for installing the SW10610R. I came up with a .063" double that completely shadows the rear baffle and also ties into the angle on the right of the oil cooler. I emulated the flow baffles on the stock double by cutting the rear baffle hole slightly large then bending them back and through the hole in the .063" doubler. I spent a lot of time carefully measuring and cutting and filing the paired holes and I'm extremely pleased with the fit and function. I riveted the rear baffle and the .063" doubler with a matrix of 1/8" rivets at 1" spacing. Probably went overboard here, but I have to say, it really stiffened up the structure, so maybe it was worth it. I orientated the oil cooler such that I was able to catch the mounting screw in the back of rear cylinder. This will take a huge amount of load off the baffling components and I'm really glad I noticed that I could use it with just a little bit of shifting. I also added a 4" long piece of .063" angle cut down on one side to the center rear baffle picking up the 1/4 mounting screw hole. This also really tightened up the structure. I had to file a large half-moon shape out of the right-rear mounting ear on the oil cooler to clear the engine mount. It is not used structurally on the oil cooler so no harm done. I opted to use all six mounting screw holes on the oil cooler instead of the normal four. This also seems to stiffen up the installation. The oil cooler is sufficiently mounted in toward the centerline such that there are no clearance issues with the cowling, although there would have been if I hadn't hogged out such a large half-moon from the oil cooler mount. The best part of the installation is that the hose fittings are nearly in the stock location, so I will be able to use the standard hose that come with the FWF kit. Whew, for once, something works without modification. All in all, I'm extremely pleased with the oil cooler installation. It is very solidly mounted, still uses the stock hoses, and clears the cowling. There are a few more pictures at (Logs 01-11): http://www.mattsrv8.com/users/display_log.php?user=MattsRV8&project=638&category=2972&log=90253&row=12 Matt Dralle RV-8 #82880 N998RV http://www.mattsrv8.com - Matt's All New RV-8 Construction Blog ________________________________________________________________________________

Subject: IO-390 Baffle Templates...
Dear Listers, I have created CAD drawings of the custom baffle pieces I made for the Lycoming IO-390 installation on my RV-8 project. Other builder's utilizing the Lycoming IO-390 in their RV-8 or RV-7 should be able to use these templates to greatly speed up the baffling installation. Note that these templates also include the cut-down for the top cowling installation. Builders may want to leave the tops longer than the templates to assure they get a good fit to the cowling. Attached are the low-res, non-scale JPGs of the templates for reference only. The high resolution, full-scale PDFs can be downloaded from my RV-8 web site: http://www.mattsrv8.com/users/display_log.php?user=MattsRV8&project=638&category=2972&log=90450&row=2 The PDFs are meant to be printed 1:1 on 11x17 paper. Be sure to use the reference dimensions in both the X and Y to verify that your printer is creating scale diagrams. Note these pieces worked on my installation, but they may or may not work on others. No guarantees that they will fit any other installation. There are many more pictures and descriptions of the installation on my RV-8 website: http://www.mattsrv8.com/users/category.php?user=MattsRV8&project=638&category=2972 Drop me an email if you decide to use these templates and let me know how they worked!

Matt, Nice work around and great pictures. I can't tell but it looks like you used aluminum fittings on the oil cooler. If this is true you need to know that they are very easy to gall. Dan C had this problem. Pacific Oil Cooler was able to repair the damage. Just a head's up to try to keep you from future problems. BTW the normal recommendation is to use steel fittings on the oil cooler.

Hi Don, Thanks for the feedback. Right now I've just got the AN822-8D aluminum fittings that Van's includes with the kit screwed into the oil cooler finger tight. I just checked Van's site and didn't find any steel versions of the AN822-8D. Is this something that Van's carries or is ACS a better bet? Do you happen to have a part number? Thanks!

Subject: Mag & Alternator Cooling Blast Tubes...
Greetings Listers, I'm looking over this cooling blast tube kit from Van's (DUCT CBT-5/8) and deciding what needs cooling and what doesn't. I'm guessing the Slick Mags do. The directions are pretty clear on how to mount the tube in the baffle, but don't mention at all where to shoot the air in around the mag. Is just in the general vacineity good enough, or is there a little hole in the mag that wants fresh air? I've also got the PlanePower 60amp alternator that Van's sells. The instruction booklet that comes with it brags about how, because of its design, it runs much cooler that traditional automobile conversions do. Okay, great. But does that mean that it still needs a blast tube off the front baffle for cooling? If so, same question on the mags. Where's a good place to stick the cool air on the alternator?

Matt, The letter D at the end of the AN822-8D part number specifies that the part is made of aluminum [Dural alloy]. Simply omit the D [AN822-8] to obtain the same part in steel. This rule applies to all AN hydraulic fittings. http://www.aircraftspruce.com/catalog/hapages/an822.php Charlie Kuss PS Using straight or 45 degree fittings will improve oil flow to and from the cooler, if space allows. 90 degree fittings should only be used when the less restrictive straight [AN816-8] or 45 degree [AN823-8] fittings will not work. http://www.aircraftspruce.com/catalog/hapages/an823.php http://www.aircraftspruce.com/catalog/hapages/an816.php --- On Sun, 10/18/09, Matt Dralle wrote: > From: Matt Dralle <dralle(at)matronics.com> > Subject: RE: RV-List: Oversized Oil Cooler Installation For IO-390... > To: rv-list(at)matronics.com > Date: Sunday, October 18, 2009, 10:47 PM > Matt Dralle > > Hi Don, > > Thanks for the feedback.

Reasons for steel Vs. aluminum fittings in the engine compartment abound. The only credible one I've heard is that the steel will be in place long after the aluminum fitting has disappeared due to fire. That makes sense to me. However, I have found no FACTUAL information that one type of fitting ever helped/caused a fire related incident. That doesn't mean that the facts aren't out there .... it just means I haven't found them. I will admit that I have had aluminum fittings in my Pitts for 28 years .... they were lighter, plentiful, less cost ...... so I used them.

I don't think steel is preferred for fire suppression. Steel is preferred for vibration protection. The fatigue life of aluminum is quite short.

Subject: Tru Trak Auto Pilot Servo
Date: Oct 21, 2009
I have a Tru Trak servo installed on my RV-7 elevator control and am picking up a sudden large resistance to movement. After almost disassembling my entire elevator system to find the "binding" I traced the problem to the servo. There is of course an expected resistance when moving the controls but I suddenly experienced a loud grinding noise which was reminiscent of say a control surface rubbing over corrugated conduit. I also found that the extra resistance was only evident when the electrical connections were made (9 - pin plug inserted) The same effect could be obtained when 4 of the 9 pins were grounded against the side of the plug. Electrical current not applied. This was not evident throughout construction and has only just manifested itself. (now that I am ready for my maiden flight!) My friends RV with identical setup does not have the resistance that I am experiencing. Any thoughts anyone?

Hi Trevor, Many builders have found interference with the F705 Bulkhead and the F789 Elevator Push Rod assembly. The problem has been the bottom or lower side of the tube rubbing on the bottom side of the cut out for the tube in the F705 Bulkhead (lower side of the cut out)... I would check this closely. Build on...

I started construction in 2001, but do not fly any more, and offering it for sale. Meticulously crafted, primed with zinc chromate. I have completed the Tail, Wings, and most of the Empennage. I even purchased the finishing kit, but have not worked on it for some time, and would be an enormous head start if you are looking to fly soon. Builder #90147. Provision for Tail light, Dual Brake, Dual Landing lights, Wingtip with provision for position lights, Static Air, Slider Canopy, Dyna/cowl for O-320, Spinner for Sensenich metal prop. Many of these options you can probably still change at this point. Currently, the Van's quickbuild price $30,200 and kit price is $20,220. I am offering this kit for $19,000, firm. In addition, I will set aside $1,000 of the payment aside for 12 months from date of purchase to pay for up to that amount in parts which are missing (I have carefully kept track of everything so I don't think this will be an issue). Kit is located in Monterey, California. I was able to move it with a 15' moving truck.

First I tied down the tail, and remov ed the front gear leg. Next, I cleaned both the top mount area and the lowe r mount area of any grease. I did the same to the gear leg, but re-greased the lower mount area where it comes into contact with the mount.

The gear leg was then inserted ba ck into the mount and the bolt partially re-inserted. (My bolt inserts from the top. The firewall has an indentation for the nut. There is no hole in the firewall for the bolt...). Next I used a small amount of "Liquid Steel" into the worn areas of the gea r leg mounting bolt holes. (Since there was very little wear, I did this in stead of drilling out the mount/gear to a larger size bolt, or inserting a taper pin.) The bolt was then torqued normally.

Subject: fuel line routing
From: thomas sargent <sarg314(at)gmail.com>
I planned a route for the fire-sleeved fuel line to my AFP divider on top of the engine, which penetrates the cooling baffle through a large grommet. I'm wondering now if the grommet can take the high temperatures in there in the 10 minutes after engine shutdown. I note that when Bart L. delivered the engine to me he had the fuel line penetrating the intercylinder baffle through a grommet (he didn't know I was going to use a crossover exhaust, so I had to re-plumb it to keep it away from the exhaust) so I guess that's where I got the idea. But now I'm wondering.... -- Tom Sargent, RV-6A, final assembly. ________________________________________________________________________________

Hi Tom, Attached are a couple of pictures of how I routed mine. I've got the 4-into-4 exhaust from Vetterman. The fuel from the TB to the distributor doesn't even come close to the exhaust. I would assume that the grommet comes with the Lycoming inter-baffle kit and is designed to handle the temps in that region. If you hear otherwise from Bart or some other authoritative source, be sure to post it to the List.

I can't offer much insight on the mags, but the critical stuff in an alternator is typically under the sheet metal on the back, or just inside the case on the back. Having said that, I would determine which way the internal fan is trying to move air through the alternator, & supply the cool air to assist the flow, instead of fighting it. The quick&dirty way to check that is to use a drill to spin up the alternator in the correct rotation & feel for the air flow.

Hi Matt, Beautiful work and pictures as always. Regarding the antennas: that area during flight will not exceed 120 F IMHO. I believe that based on an extra digital temp probe I move around my engine compartment for testing of different areas. The tubes will work against you at shut down. Do you have the opportunity to get an extra temperature probe stuck in there? You seem like the kind of guy that would enjoy the extra data collection. And I know you have lots of electronics aboard! And regarding Alternator temps, my 70 amp never went above 160 F without cooling tube, although I normally have one. And that is the peak after shut down, peak in flight was 135 F without and 125 F with cooling tube. Dale RV6a 1245 hrs, O-360 A1A, dual electronic ignition, dual electric.

Matt, Just commenting on the blast tubes to your antenna tray:- It appears that you intend for the tray to screw to the cowling when it's in place, or tha t you intend to fix a cover to the top of the tray.- In either case, the tray will be a dead space without an area for the incoming air from the bla st tubes to exit.- In this case, the blast tube won't provide any cooling air flow, just positive ram air pressure during flight.- As others have pointed out, the tube may just create a conduit for heat soak to warm the a ntennas after a hot shut down.- I would probably leave those tube off of the antenna tray.

Subject: Mag & Alternator Cooling Blast Tubes...
Matt, Many Lycomings have shrouds as well as blast tubes for the magnetos. I purchased a pair of used magneto shrouds from a local certified engine shop. Heat and vibration are the enemies of anything electrical, like magnetos and alternators. To properly protect an ND alternator, you need to understand how the cooling fans work. Your PlanePower ND alternator has two internal fans [mounted on the rotor shaft, internal to the cases]. These fans draw air in from both the front and the rear of the alternator case. This air is expelled through the slots located around the middle circumference of the alternator. Lycoming engines spin opposite to what most car engines rotate. Honda engines rotate clockwise, as do our Lycomings. This means that an ND alternator off of something other than a Honda, will have the fans running backwards. Planepower's brag relates to the fact that it has the correct fan rotation for optimum cooling [clockwise]. I would recommend that you either aim your blast tube towards the rear of your alternator. An even better option would be to fabricate a shroud for the rear of the alternator and install the blast tube to the shroud. See attached photos of David Brand's very nice alternator shroud. For folks using an ND alternator with internal fans which is NOT from a Honda, aim the blast tube at the slots around the circumference of the middle of the unit. Since the fans will be running in reverse, the air is being drawn in where it should be expelled. I hope this helps. Charlie Kuss PS I'll try to take a photo of my magneto shrouds later today. I'm looking over this cooling blast tube kit from Van's (DUCT CBT-5/8) and deciding what needs cooling and what doesn't. I'm guessing the Slick Mags do. The directions are pretty clear on how to mount the tube in the baffle, but don't mention at all where to shoot the air in around the mag.

Chris, These are for Bendix [now TCM] magnetos. The top of the magneto is held on with 5 machine screws. The mounting brackets nest between the heads of 4 of those top screws and the top cap of the magneto. Something similar could be fashioned for the Slick units.

Subject: Re: Using the firmer engine mounts.
The stiffer aerobatic mounts keep the engine from moving around during violent maneuvers. Your mount sagging is plainly due to constant pressure, not the transient pressure of aerobatics. My suggestion ..... because I'm cheap .... is to place washers under the lower mounts to raise the engine back up.

Subject: Airing up the tires through the wheel pants.
Date: Nov 01, 2009
My Wheel pants have been installed on my airplane for less than a year and I am already finding the disadvantage of checking/ filling the air in the tires. I am sure there has been discussion of putting holes in the wheel pants for access to the valve stem. Does anyone have any photos on their building sites of where to put these holes, how big, and what if anything is used to plug the holes? I would appreciate any feedback on this simple thing.

I purchased little snap in plugs at Home Depot. They carry sizes ranging from 1/4" to over 1". I think mine are 7/8". The plugs come in plastic and polished (stainless?) steel. I got the steel ones. Aircraft Spruce also carries little hinged doors if you want to spend 20 bucks instead of $2. To locate the holes, all I did was measure the distance from the axle of the wheel to the center of the valve stem, then drilled a 7/8" hole that distance from the hole in the wheelpant where the bolt goes into the axle nut. It was probably 2" or 2 1/4", but don't trust that measurement - measure for yourself. On mine, the hole is in the front half of the wheelpant, but I'm not sure that's important.

Kelly, Lynn, others, This may be a dumb question, but wondering if everyone is talking the same location for washers. I have seen washers mounted under isolation mounts as it seems most are talking about but I have also seen 970's added under the engine mount to firewall gussets. I have used both locations for different purposes. One to reposition the isolation mount geometry and one to reposition the whole mount and engine. I know of one occasion where the spacer inside the mount was reduced in length to tighten up the isolation mount. I would think they present different problems and or solutions. The engine tends to change it's weight on the mounts during flight and moves around a lot during cranking, shutdown and anything other than 1 G flight. On the other hand the mount to firewall fit is more rigid and tends to stay where you bolt it. However a loose bolt or lost washer at that location is possibly more troublesome as the bolt size there may not be sufficient, given the abuse that occurs when they are loose. I also have a sagging engine and was planning on going with one or two 970's between the mount and firewall, but also realize that in flight the engine may not be sagging as much. It seems that most commenting on this thread are putting a 970 washer under the isolation mount but I don't see how that will tighten up the isolation mount without treating the internal spacer. I don't do any negative G stuff (on purpose anyway) and generally never exceed 3 to 3.5 G positive but the engine still moves around a lot with gyroscopic actions as well as simple G loads. Is the concensus that short of changing out the mounts, the best approach is to washer up the isolation mounts? I know the best solution would probably be to replace the kit iso mounts with Lord mounts but what is the consensus for next best solution.

Subject: Re: Airing up the tires through the wheel pants.
To answer your-question-it is very simple, you need an access-hole (s quare or round) and a plug or cover. You just have to align it with the valve stem. You'll use an air-chuck with an extension. The most common access is round and one of those SNAP-IN BUTTON COVERS-or PLUGS-(or hole plugs), in metal or plastic/nylon. - http://www.surplussales.com/MetalPlugs/MetalHolePlugs.html - http://www.widgetco.com/hole-plugs - http://www.surplussales.com/Rubber-Plastic/Plastic-1.html - You need to figure out what air tool you will use, for the geometry. - http://www.drillspot.com/products/41080/Dynaquip_AC45_Straight_Body_Air_Chu ck (this is best, with a length of brass tube as needed) - http://www.savinglots.com/lotprod.asp?item=JL5010N (takes up a little more room with the side fitting) - Just a stripe of white paint where the air-stem is so you can align it with the hole in the wheel pants will make it easier. Also to check the air-pressure , you can use the same air-check to a quick disconnect. Than you just plug in the AIR-GAGE into the quick disconnect. So you will need the following: - -Hole Plug -Straight Air-Chuck -Female quick disconnect -Air-Gage with male quick disconnect -Small length of brass tube with 1/4" NFPT (threaded ends) (you can bend the brass pipe slightly than cut, than-thread if you want a slight-angle) (if you use an angle or dual air-chuck you will need at least a-1.25" hol e) - My solution was to use good quality tubes, tires and nitrogen,-so I don't have- to deal with checking or filling them as often. However having access is a good idea. However to get half-back half- of my wheel pants off is-only a handful of Philips screws; it takes about a minute to remove or install. So I decided against it. - Others make a square hole with a small hinged cover to make LOTS of room so you can put in any old big dual chuck, with out having the tire rotated -the tire just the right spot. - - >My Wheel pants have been installed on my airplane for less than a year and I >am already finding the disadvantage of checking/ filling the air in the >tires.- I am sure there has been discussion of putting holes in the whee l >pants for access to the valve stem.- Does anyone have any photos on thei r >building sites of where to put these holes, how big, and what if anything is >used to plug the holes?- I would appreciate any feedback on this simple >thing.=0A=0A=0A ________________________________________________________________________________

The mount bolts are not as accessible (like on the inside) as the isolators, so I typically work on the isolators. Putting washers under one or two of the airframe bolts also stresses the steel mount.

The washer goes forward of the isolator and the flat on the engine mounting ears if you have the ring type isolator mounts. On mounts where the isolator is cone shaped and sandwiches the mounting ear, then the washer will be behind the isolator. > > I don't do any negative G stuff (on purpose anyway) and generally never > exceed 3 to 3.5 G positive but the engine still moves around a lot with > gyroscopic actions as well as simple G loads.

Subject: Re: Engine mount washer thickness calculation
From: Ian <ixb(at)videotron.ca>
Date: Nov 03, 2009
You'll have to do some measuring to figure out the width of the washers, but my schoolboy trig would have it that the thickness of the washers would be given by: Thickness required = 3/8" * Distance from top mounting bolts to bottom mounting bolts/Distance from top mounting bolts to base of spinner. This is based on the sine law. The triangle having the angle that includes the 3/8" measurement and the triangle that includes the required washer calculation would both have the same angle (sine). Opposite over hypotenuse in both cases becomes the same value. So, measure the distance from the firewall to the spinner and from the top to the bottom mounting bolts and divide the smaller number by the bigger one and use it to multiply by the height required (3/8", .375" or .9525 millimeters).

FWIW, when I moved my 9A fuselage with engine mounted I used a U-Haul box van. The dimensions are slightly wider than the footprint of the 9A but the doorway is slightly narrower. This meant getting the aircraft up ramps to the almost-in position, and then doing a sideways jog to get the wheel nuts past the door frame. It was a fairly short trip but I had no problem moving it with the engine mounted - either during or after. The engine/prop were sticking out of the open door! If the mount is designed to withstand a hard landing I assume it's also built to withstand similar stresses on a road trip. By the way, if you try to do this, the typical U-Haul van comes with only one ramp. I used a ladder with an assortment of boards on it for the other main wheel, and friends to balance the nosewheel to the right angle. A combination of a come-along and people turning the wheels by hand managed to get it up the ramp nicely.

I think only half the idea was expressed. The real concern would be to mount the engine on a temp basis, with bolts to the firewall NOT torqued properly. Then it could bounce around and hammer the mount area. Similar lesson to the story of the canopy that was not secured. Same could happen if wings were not properly secured.

Subject: Apollo GX-60 with a Dynon??
Has anyone flown with a Dynon EFIS & Apollo GX60 (for IFR)? If so, is it a reasonable combination? Is the HS34 required or advisable, and can the Dynon serve as the CDI for approaches? I'm not yet instrument rated & *if* I can get around to getting the rating, I'll still be a big enough coward to only use it to get up through and back down through a layer to good conditions. It's hard to justify the money for a 430W when there's a good chance I'll never use its real power, & GX60's can be had for a much more tolerable price. Thanks for any insight, Charlie ________________________________________________________________________________

Subject: Air in fuel lines
Date: Nov 06, 2009
Hi all: Been having a lot of trouble with a rough idle problem on my Fuel Injected 0-360 parallel valve engine. I've been going through several tests trying to locate the source of the problem but so far no joy. One suggestion that I have received concerns air getting into the fuel lines. It seems a little far fetched that air could get in through a fitting that is not leaking fuel but I'm running out of ideas so I'll go through and tighten all my fittings to see if that helps. But, that leaves one other possibility and that's air getting in through the fuel selector valve. I'm using the Van's fuel selector that came with my RV-6 kit. It sat in its little brown bag on the shelf in my shop for several years before it got used but seems to working fine. It's not hard to move the selector and its not leaking, at least externally. Anyone experience leaking of this valve or any issue with that might let air into the fuel lines through it? Any ideas on how I might test the valve to see if it's leaking air into the system? I'm using the Van's high pressure pump setup that puts the pump ahead of the selector valve so there will be some suction at the valve. I'm running out of ideas and thinking about switching to a carb. Hate to do that but can't find anything wrong after working on it for the last year, maddening. Thanks.

There are no replacement display panels. When the panel dies the unit is nothing but a spare parts unit. Garmin chose to not acquire any spares beyond what they got when they bought the company.

The site looks very slick & professional however the content is quite lacking. I agree with others about additional DETAILED images and text. Having been around the RV community for some time I have seen many accessories developed for these planes all using generally the same development model. Someone has an idea and discusses it with the RV List and/or Vans Airforce for feedback and further development. Now maybe I missed something but items as significant as Wing Modifications (High Lift Wing) and Winglest are such significant changes to an important component like a the major lifting body cause visitors to disbelieve their value if there is no history, documentation, detailed images (including design, construction & installation) and data supporting the benefits of these modifications. The few images of Winglets shows commercial units. While the people behind the site may have some connection to these units there is no comfort in this knowledge when the site is lacking for the items the RV communit.

____________________________________ From: 144tomjones(at)gmail.com CC: rv-list(at)matronics.com Sent: 11/11/2009 4:33:15 P.M. Pacific Standard Time Subj: SELECTOR VALVE AIR LEAKS. Dean, Jess Meyers of Belted Air Power discovered this many years ago: If the pump is sucking fuel through the valve (not pushing) it can pull air past the "O" ring seals around the selector valve shaft. Fuel will not necessarily leak from the valve, in fact it seldom if ever does in this type of situation, but it will surely pull air into the fuel! This is just like having a pin hole in a soda straw and trying to suck soda from a bottle, it will induce air bubbles from the atmosphere into the straw causing loss of vacuum and dilution of the soda with air. This same phenomena occurs in fuel with even worse effects. The fuel draw is reduced to the point of inadequate fuel to the injectors or carburetor, possible vapor lock, and or foaming in the carburetor bowl causing the float to rise to a false level limiting the fuel flow through the needle valve and possibly completely shutting off the needle valve. Any of these occurrences can cause fuel starvation and is only exacerbated by turning on of a second or booster pump as it only sucks in more air! And yet it may show good fuel pressure! Watch the accident reports and see how many times an engine failed and when checked afterwards there was fuel in the system, but it just stopped running. We hear of reports where the pilot experienced a rough running engine and took the proper action to turn on a boost pump only to have the engine run even worse or stop all together. Jess has been putting this notice out for many years but unfortunately few seem to understand it well enough to heed the warning.

Subject: bleeding brakes?
From: thomas sargent <sarg314(at)gmail.com>
I will soon need to pour some brake fluid into my RV-6A and, I presume, to bleed the brakes. I've never done this on a car, let alone a plane. Can some one direct me to a web page that explains the process? Thanks, -- Tom Sargent, RV-6A final assembly. ________________________________________________________________________________

Subject: Re: bleeding brakes?
No website, but my best advice would be to get someone from your local EAA chapter (you should already be a member!!!) to help you do it the first time. It's easy to end up with spongy brakes. Lacking that, the simple and best way is to use a squeeze-type oil can and force fluid through the bleed fitting on the brake cylinder. An adapter with a short piece of hose on the master cylinder will allow you to catch overflow in a container. Bleed one side, then the other.

Subject: trimming wheel fairing tire opening
From: thomas sargent <sarg314(at)gmail.com>
I am concerned that the opening for the tire in my wheel fairings might not be large enough, or perhaps I should say high enough. It seems to me that if your tire goes flat, the wheel fairing should be trimmed high enough so that the bottom of the fairing doesn't touch the ground. Otherwise the weight of the plane will be on the fairing rather than the tire. Is this an excessive amount of trimming? I'm sure some of you had the experience of opening the hangar and finding a flat. How did your fairings come through the experience and how high do you have them trimmed? Thanks, -- Tom Sargent ________________________________________________________________________________

Its all up to you Tom=2C but I would think that setting the pants up so hig h as to protect them from a flat tire would take away some of their effecti veness. The more tire you can cover=2C the more they will help you go fast . Mine are pretty low=2C and I have damaged them twice. Once from a tire stem malfunction during inflation=2C and once taxiing from a hard surface t o grass=2C the height of the taxiway was just a little high compared to the grass. All I can say is think about where you will be using your plane an d set the pant height accordingly.

Subject: Contributions Down By 21%...
Dear Listers, As of today, contributions to the Matronics List Fund Raiser are lagging behind last year at this time by 21%. I have a fund raiser each year simply to cover my operating costs for the Lists. I *do not* accept any advertising income to support the Lists and rely solely on the contributions of members to keep the expenses paid. I run all of my own servers and they are housed here locally, and the Internet connection is a commercial-grade, T1 connection with public address space. I also maintain a full backup system that does nightly backups of all List-related data so that in the event of a server crash or worse, all of the Lists and the many years of List archive data could be restored onto a new server in a matter of hours. All of this costs a fair amount of money, not to mention a significant amount of my personal time as well. I have a Fund Raiser each year to cover these costs and I ask that members that feel they receive a benefit from my investments, make a modest contribution each year to support the continued operation and upgrade of these services. If you enjoy the Lists, please make a contribution today. I also offer some incentive gifts for larger contribution levels. At the Contribution Web Wite, you can use a credit card, Paypal, or personal check to show your support for the continuation of these services: http://www.matronics.com/contribution Thank you for your support!

Subject: Oil cooler attachment bolts
I have a SW 8406R oil cooler on my IO360B1F6 in my RV6A. Temps are fine - even on hot summer days. Three of the attachment bolts go through both sets of oil cooler flanges (and in to the back of the #4 baffle plate) with an aluminum tube providing support between the flanges. One of the bolts only goes through the 'forward' oil cooler flange and in to the baffle - per Vans oil cooler installation instructions. I would like to add a Reiff Oil-Cooler-Heater on the side with the single bolt going through only one flange. It gets cold here on the DelMarVa peninsula in the winter. In order to do that, I would need to make the other bolt on that side go only through the 'forward' flange as well. Does anyone know any reason that I shouldn't do this? Maybe you need pictures to figure out my description. I'll try to take some them to show. Thanks, Ralph ________________________________________________________________________________

Walt, I don't have a web page. I use carpeting scraps to prevent scratching of aluminum sheet parts. I usually place this on the work bench just prior to removing the plastic coating.

Subject: Brakes
Date: Nov 18, 2009
Hi Dave Yes, I did install the thicker rotors on my RV-6A. I really love the solid feel I now have. Since they are twice the mass, the same amount of heat energy only raises the rotor temperature approx 1/2 of the thinner rotors - helps keeps the seals from cooking as well as helping to prevent temps high enough to set off the brake fluid. Aircraft Spruce at one time (and may still) offered a thicker rotor kit #199-93 assembly. However, at the time it was close to $350 and I decided to see if I could do better (did!). The Cleveland/parker part number for the thicker rotor disc is 164-09900. However, I used the Rappco part RA 164-09900 from Chief Aircraft for $84.00 each http://www.chiefaircraft.com/airsec/Aircraft/Brakes/BrakeDiscs.html That was the expense 2 * 84 = $168 for both rotors, the rest of the fittings I made in my shop. There were the 1/8" pad spacer described below and the longer aluminum bushings to stand off the wheel pant. At the time I made up some new wheel pant brackets out of SS since I had lost one on the burnt up wheel pant. Now some of the more recent RVs (such as the 8s) have a slightly different brake set up due to the plate gear rod - so this may not apply to them. Otherwise, pretty straight forward. You do have to have a 1/8" (0.125") shim plate to place between the two pad holders to compensate for the thicker rotor for each wheel. If you buy them they cost about the same as the rotors, the cheapest I could find were $84.00 EACH - which I though absurd given the rotors only cost $85 each. So I made mine out of 6061-T6 1/8" aluminum plate/sheet. They will have to be curved on the underside (axle edge) to match the curvature of the rotor - but not a big job. The most critical thing (and not that hard) is to make certain the holes in the plate match the pad holes - you don't want the spacer binding. Took me approx 30 minutes to make both. I anodize them for corrosion resistance. Also, I had to lengthen the aluminum tubes used to stand off the wheel pant attachment bracket by approx 1/8" otherwise the thicker rotor wanted to rub on the bracket. Again, no biggie. I also switched to stainless steel braided Teflon brake lines, they give the brakes a much more solid feel and much less likely to rupture. I personally will never go back to the aluminum lines myself - but that is just my personal viewpoint, thousands are flying with them.

Tom, I've done both and I prefer the manual. The electric is very sensitive at cruise but works well in the pattern. I've seen various devices to ch ange the speed of the servo depending on your airspeed but they are expe nsive and add complexity. I'll take the weight penalty of the manual.

Subject: Re: elevator trim, manual vs electric
Date: Nov 18, 2009
This is a tough trade off analysis, and a lot of it is purely subjective; Here's my take. Cost: the manual is far cheaper Installation: I believe the Installation is slightly easier on the electric but shoe horning that servo in to the elevator is not easy. If the Gretz version is still available, it makes the electric way easier. weight: The electric is far lighter. Space: The manual takes up a bit of space in the cockpit so the electric gets the nod. Feel: This is very subjective to say the least. For my money the manual has a far better feel and preciseness. To add to the bargain you can see what you got for take off or go around. Easier to set, and quicker too. Most pilots don't like the lack of feed back from the electric servo and its slowness. You can get various speed changers and gain switchers. Bottom line is most pilots who have flown with electric trim before can get accustomed to the shortcomings. I did. Safety: Probably the most debated issue. Surely "runaway trim" is a possibility with the electric. It is not a possibility with the manual. I know lots of folks will come after me for saying this, but I don't think it is a significant problem in an RV-6A. First of all most of the dark and stormy night horror stories are about big airplanes with stabilizer trim. On the B-52 it was a real threat. The huge hydraulic motors could drive the huge stabilizer very quickly to a position far beyond you ability to overcome the pitch force with the puny elevator. With elevator trim in the RV 6A. you do not lose elevator effectiveness when the trim tab takes off. For example if the trim runs away to full down (tab up) and you counter it with up elevator, then your effective elevator power is actually more than if the tab were elsewhere. I have tested many times and the elevator force required to overcome full up trim on take off is easily manageable. I don't know how fast you can go and still control it with our using both hands but I believe it is do able. I leave it to Kevin Horton to do this test for us. As for me I installed a pullable circuit breaker for the trim power which is easily accessible. It has never been used in flight. I went with the electric and have had several failures, all broken wires. I replaced most of the wires with mil spec 22 ga and solved that problem. These failures would cause me to lose trim altogether. Basically an inconvenience in the RV-6A. Good luck on your choice.. I like both systems, but went with the electric and have no regrets. My little servo has 2400 hours on it and still works. I used the matronics speed controller and ordered a new improved one after the old one was ten years old, got rained on, and became intermittent. When pulling it out to switch I found a loose connection so it is still in the plane (with a rain guard) and I have a spare if you want to make an offer. ; ). LET THE flames begin on my rant about runaway trim. I would surely like to hear from someone who has experienced it with an RV-6.

I have 2000 plus hours on my RV8 with the electric trim on aeleron and elevater. I installed a 4 position top hat switch on the top of the control stick for easy operation. The only mod was to install a speed reducer on the elevator trim motor. It was an easy install. The speed reducer is necessaary on the elevator inorder to fine tune elevator cruise position. The aeleron trim allows me to use all of the fuel from each tank at one time on long trips . It is nice to know exactly when a tank is out on a long trip. I did not use tabs for the trim. I cut sections from the trailing edge and made new pieces that are hinged as a part of the aeleron /eleator. Nothing sticks out. It takes time to do this, but i found it well worth the effort. Dick Martin RV8 N233M IO-390 the fast one ----- Original Message ----- From: thomas sargent To: rv-list Sent: Wednesday, November 18, 2009 11:19 AM Subject: RV-List: elevator trim, manual vs electric I am doing final assembly on a 6A. I've never had the trim cable fully installed before and am running into various problems that have me reconsidering things. The manual trim has the advantage that it is not electric - no wiring, no dependence on the electrical system. I also like the very positive connection from my hand to the trim tab. But, (I'm guessing here) the electric looks like it's a lot easier to install. It's probably also a lot lighter. Though, I've heard lots of stories about the servo's running away. Have any of you converted from manual trim to electric? Is the electric easier to install/live with? -- Tom Sargent ________________________________________________________________________________

I have manual trim and am not flying yet. But one thing it kinda hoses up is wiring runs. One of the holes on the left side of the tunnel in my RV-7a is dedicated to a big manual trim cable (and also an ELT wiring run. ) I don't have much electrical stuff in the plane but the hole right side of the tunnel is full up with two strobe cables, a strobe power cable, a nav light cable, and an ELT instrument panel light cable. I could sure use some more room back there. and I havne't even run any antenna cables yet. _____ From: owner-rv-list-server(at)matronics.com [mailto:owner-rv-list-server(at)matronics.com] On Behalf Of Ralph Finch Sent: Thursday, November 19, 2009 9:40 AM Subject: RE: RV-List: elevator trim, manual vs electric Can you explain further?

Subject: Just A Few Days Left; Still Trailing Last Year...
Dear Listers, There are just a few more days left of this year's List Fund Raiser! Response has been very good, but still well behind last year. If you've been waiting until the last minute to make your contribution and maybe even pick up a great gift, now might be good time to show your support! Please remember that there isn't any sort of commercial advertising on the Lists and the *only* means of keeping these Lists running is through your Contributions during this Fund Raiser. Please make a Contribution today! http://www.matronics.com/contribution Thank you!

For those of you who wonder why the list is so long, and whether you can do anything to help reduce it, consider deleting most or all of the text of the message you are replying to. It would really help not to have to read someone else's privacy statement six times. Ideally, just keep the line or two of text relevant to what you are replying to. Respectfully, Ian Brown, RV-9A, Bromont, Quebec ________________________________________________________________________________

Ok so I built a new set of RV4 tanks for a client in Germany. We had a bit of a miscommunication and I sent him a set for a new model (prepunched skins) wing and his is an early model so he cant use them. I ended up building a new set for him but still need to find a home for the first set. It is cost prohibitive to ship them this direction for some reason so I am looking for someone who can use them on that side of the globe. They are brand new, set up with aerobatic mods on the left side and have Stewart Warner senders installed. I would like to get $1000.00 for them....this is less than half of the retail value. I will entertain any offers of cash or trade (I am currently building an RV9A) Or, If anybody out there has any super deals on shipping them back here, (California) I would sure like to hear about it. I have been told that the military boys get to ship really cheap :) Cheers.. Evan evmeg(at)snowcrest.net ________________________________________________________________________________

What I have done in the past is to extend the line from the wing down through the mount so you can attach the line externally, then push the pitot with the attached line into the mount and secure. Then later it is servicable without opening the wing. -Mike Sent from my iPhone On Nov 20, 2009, at 11:26 PM, "emrath" wrote: > > Folks, > I have a Gretz Heated Pitot Tube and mount.

Subject: 6A elevator trim tab set-up
From: thomas sargent <sarg314(at)gmail.com>
I have the manual trim cable installed enough to measure up/down deflection on the trim tab. The manual says 35 deg. down (for nose-up trim) and 25 deg. up. How is that measured? I assume that since the hinge is at the top skin, that you measure it from elev. top skin to trim tab top skin. If that is right, I have about 34 deg. down, but only about 21 deg. up, using the full travel of the trim cable (about 2.3"). Is this something I have to fix? The only way to fix it that I can see is to rivet some aluminum onto the arm of the trim tab so I could make a new attachment point for the cable which would be a little closer to the tab. That would get me more deflection for my 2.3" of motion. The throw of the cable could be increased by removing the locking ring. I don't think I want to do that. Another issue is that the nut that secures the end of the cable. The one which is welded to the little piece of steel. It is about 1/4" above the plate that it is supposed to be pop riveted to. Is this typical? There is no way I can attach it to the cover plate without a substantial spacer. I'm also thinking of holding it in with a couple plate nuts rather than the pop rivets. Seems like the cover plate would be next to impossible to remove if the steel plate was riveted to it. Screws would make it easy to remove. Has any one else had these problems? -- Tom Sargent, RV-6A final assembly. ________________________________________________________________________________

I used non-skid rug underlayment. It appears to be like a fine mesh, knotted netting that has been dipped in a soft foam rubber material. The end result is a very flexible sheet of what looks like small beads stuck to each other. The softness cushions the wing skins, the non-skid aspect keeps your work from sliding around, and the gaps / holes in the material provide a place for drilling and deburring chips etc to go such that they can't scratch the aluminum. It can be gotten as drawer liner, but it is MUCH cheaper to get it as rug underlayment from Target, Wally world, or some such.

Tom, I would not worry about the small deflection problem because you will find that the trim tab is so sensitive that very little movement will be required of it. As for your anchor plate that is a different story. Why is it so far removed from the cover plate? It may be that if it were positioned properly you would recover the lost deflection.

From: "Robin Marks" <robin1(at)mrmoisture.com>
Anyone out there recording in flight HD videos? I recall seeing a tail mounted bullet camera and some semi-wide angle video that was fantastic. I want to record in flight videos in a similar way. I thought about mounting a HD bullet camera in the fiberglass section of the vertical stabilizer but I cannot find any 12V HD DVR's that are an acceptable size and weight. Most of them are low resolution Security DVR's. A second fly in the ointment is I want to pull the audio in from the audio panel vs. just an open air mic. There seem to be some combination choices like these: Really Small but not HD and no audio input. Or this one: 1080P but no external audio feed. This is an all in one unit so no remote mounting as you have to have access to turn on/off The nice part about this is it's movable Same with this unit: 1080P but no external audio feed. This is an all in one unit so no remote mounting as you have to have access to turn on/off The nice part about this is it's movable Now I made a BIG mistake by mounting two DVD players in my RV-10 when portable ones would have been a much better choice due to advances in technology but I figured mounting an HD camera is not that big a deal as the most important part is the capture device (DVR) but as I can't find any (except the Sony for $3,000) maybe the helmet style is best. I believe this is another example of something I want/need now but the market has not quite caught up with my requirements. Any guidance would be appreciated.

Subject: Re: elevator trim, manual vs electric
Manual trim is far more precise when setting the trim. It gives a good "touch" making it far easier to get the perfect trim. That is, it gives an excellent feel for where the trim is or needs to be. Electric trim really begs for a motor speed reducer to minimize overrunning (chasing) the desired trim. I love my manual trim and would do it again. I moved mine from between the seats (RV-6) over to the left of the cockpit mounted against the fuselage left wall. I operate it with my left hand. The cable slopes down from the control knob on a 45 degree angle and then loops up along the fuselage wall (near my left knee) and reward running under the left longeron to the rear of the airplane. Neat and out of the way. Pete in Clearwater RV-6, Reserve Grand Champion S 'n F and other awards ________________________________________________________________________________

Bob: Yes, I think they're in the right place. There's no discretion in placing the hole in the HS rear spar - there is just barely room for it between the 2 reinforcing bars. As for the elvator, I checked my plans. My drawings are from 1996 (!). The hole in the elevator spar is shown, but no dimensions are specified to locate it. It is towards the bottom of the spar. I could have put it a bit lower (maybe 3/16") before running into anything, but I'm not sure that would still line up well enough with the hole in the H.S. There's only a 2 or 3 inches between the HS spar and the elevator spar. I just made it look like the drawing. I noticed that I didn't have the fork screwed onto the threaded on of the cable completely, so I did that which allowed me to pull the cable a about 3/8" further aft. That brought the anchor plate into slightly better position. Still looks like I'm going to need a 3/16" spacer between it and the cover plate though. I'll call Van's in the morning.

As many of you may know, I have been obsessing a bit about my CHT's...to get them consistent. Here's the setup: IO360B1F6 9.2:1 pistons AFP Fuel Injection LASAR Ignition with CHT sender relocated to allow for testing Vetterman Dual Crossover Heater/Mufflers SamJames cowl and plenum Advanced Flight Systems 3400 Engine Monitor Oil Cooler mounted behind #4 cylinder Air for both Heater/Mufflers behind #3 cylinder For constant power setting, here's the consistency that I have achieved: #1 and #3 cylinders run within three degrees (avg) of each other #2 and #4 cylinders run within three degrees (avg) of each other The #1/#3 cylinders run 8.5 degrees hotter (avg) than the #2/#4 cylinders With the members of the sets of cylinders running this close each other, I'm thinking that I have the balance (front to rear) for each side pretty well matched. I'm trying to wrap my head around what could be causing the right side to run hotter than the left. Here's some of what I'm thinking...: With this plenum set-up, I'm thinking that the pressure/volume should equalize from left to right. This would leave me with not much to change to cause more cooling air to go from the left to the right - meaning that I probably have to live with the differences. Alternatively, maybe it's not really hotter...the two sets of CHT wires for the left side (both equal length) are about three feet longer than the ones for the right side (again, both equal length). Could the difference in the lengths of the wires account for the reported temperature difference? I'm pretty close to thinking that this is as good as it gets...but I would really like to know why...

Ralph, Have you installed an AN960 washer between the rear baffle & cylinder head on the #3 cylinder? The #2 & #3 cylinders have very thin fins between the head itself and the [front on #2] rear baffle. By installing a single washer between the above mentioned parts, for the bolt that holds the rear baffle onto #3, you will reduce the temp on #3. You will then have to cut down the air dam in front of #1 to even out that side. This should help to reduce the side to side variation you have.

Ralph, As one who has been perplexed by temperatures (RV-10, James Cowl, Plenum etc...) I would sleep quite well at night with your numbers. If you are looking for reasons why one bank is different that the other you can consider the oil cooler asymmetry or prop rotation or maybe some differences on the lower portion of the fire wall forward making exit air asymmetrical or you can put some of this on the sensors ability to resolve these very small differences in relative temperature. As far as the "pressure volume equalizing left to right" maybe yes, maybe no. I suspect proving this may be very difficult w/o extensive R&D for what benefit? Cutting the difference in half so you are within 4 degrees left/right. I tend to think of the air under the Cowl/Plenum as a frantic tumbling & crashing of molecules with a large amount of air reversing course and exiting out the front of the cowl. It is not a smooth aerodynamic "flow through" environment under the hood. I think even with your numbers you can retain bragging rights over 99% of aircraft flying today. An alternative solution is to revert back to a single CHT/EGT probe and consider them all the same. Wa-la perfect balance!

Subject: Re: CHT update
If your end results are all cylinders staying below 400 in climb and preferably below 380, your balance between cylinders, both front to rear and side to side is more than adequate. As for reasons the right side is hotter, it is last in the oil delivery plumbing, so the lifters and rocker boxes get about 1/2 what the left side gets. Most Lycomings have #2 and #3 run hottest because of too tight cowling in front of #2 and behind #3, where there are no fins on the intake side of head, so only with a little spacing, perhaps 1/8" will you get airflow over that side of the cylinder. The spacer is worth about 30 degrees cooler. Ralph E.

Many of us will be traveling to be with our families and friends to share in generous feasts of plenty and giving thanks for many blessings that have been bestowed upon us. Many Listers have expressed over the last couple of weeks how thankful they are for the Email Lists and Forums here on the Matronics servers and for all of the assistance and comradery they have experienced being a part of the Lists. One of my favorite comments is when someone writes to me and says something like, "Its the first thing I do in the morning while I'm having my morning coffee!". That's a wonderful tribute to the purpose and function of these Lists. Its always great to hear I'm not the only one that jumps out of bed each morning to check my List email!! Won't you take a minute today and show your appreciation for these Lists and for their continued operation and upgrade? The List Contribution Site is: http://www.matronics.com/contribution Thank you in advance for your kind consideration, Matt Dralle Matronics Email List Administrator ________________________________________________________________________________

Subject: RV-8 - Baggage Door Strut...
Dear Listers, The stock front baggage door on the RV-8 doesn't come with any means of holding it open other than your arm. Since I'd already experienced what happens when the latch pins are in the "latched" position and the door suddenly slams shut (dents and scratches), I really wanted to find a nice strut of some kind that would hold the door open, yet be relatively easy to install/replace/use. Some browsing in the McMaster-Carr on-line catalog turned up what turn out to be the absolute *perfect* part for the job. The strut unit is made for tool box lids and has pre-installed mounts on each end that work perfectly on the RV-8 baggage door with no modifications whatsoever. Incredible, really. The best part is that in operation, and using the mounting dimensions shown in the pictures, the strut will securely hold the door open AND closed! Its amazing actually! At about 2" from closed the geometry of the system has nearly zero pressure open/closed and then at the last 1" or so, slightly pulls the door down. Note that the latch pins are still needed to hold the door securely closed. Conversely, after about 3" open, there is enough push in the spring to gently open the door all the way and then hold it open very nicely. If you have an RV-8 and want a baggage door strut, look no further. This is the perfect ticket: McMaster-Carr Part Number: 11615A14 Here is the on-line web page for the part: http://www.mcmaster.com/#11615A14 At $34.75 (circa 2009) its a little pricey, but its stainless steel and did I mention - works PERFECTLY on the RV-8 front baggage door! Buy one now! I used three standard LP4-3 pop rivets on the top attachment hinge to the side of the baggage door, and two #8 platenuts and screws on the lower attachment. For the correct geometry, you'll want to mount the upper hinge exactly 11/16" from the bottom of the door as shown in the pictures. The lower hinge should be mounted exactly 8.0" from the exterior skin of the fuselage as shown in the picture.

Subject: No "Black Friday" For List Fund Raiser...
Even though the number of List subscriptions and List posts are up significantly this year compared to last year, support during this year's List Fund Raiser has been woefully lagging from last year. There are only a couple more days left in November and the end of the Fund Raiser is quickly approaching. I have always preferred a non-commercial List experience as many, many members have also expressed that they do as well. However, if the yearly fund raiser cannot generate sufficient funds to keep the bills paid on the List service expenses, I will have to look into some sort of advertising. Please don't let that happen! Your personal contribution of $20 or $30 goes a long ways to keeping the operation a float. The lunch combo at Carl's Jr costs nearly $10 these days. Isn't the List worth at least as much as a couple of burgers? Please make sure your name is on this year's List of Contributors published in December.

I'm looking for a pointer to a set of plans (or photos) for a "cart" that I can use to hold my wings. Nothing fancy, just a plywood and 2 x 4 cart with wheels is all I'm looking for.

Subject: Re: Wing cart pointer
Hi Richard, No plans, but a good idea of what I did: http://caura.dyndns.org/gallery/Right-Wing/afo I used a wing rib as a template for the cutouts. I notched the inboard ends to keep the main spar from vibrating/bouncing off while moving things around. I used the plywood from the "wing kit" and some 2x4's. There's a long 2x4 that joins the two ends. On each end, there is a 2x4 at a 45 deg angle that attaches to the side and the "long 2x4" (sorry, no pic - just some ascii art below). These provide support for the sides so they "flop over". |\ /| | \ / | | \ / | ----------------- Things I'd do again: - Find some old casters and install them. Makes moving _very_ easy. - Bottoms of the wings facing outward Things I'd change or do differently: - You'll notice that for each caster, I doubled up on the 2x4's. I should have sandwiched the vertical portions of the cradle w/ the 2x4's rather than stacked the 2x4's. Reason being, the plywood is not the sturdiest material and now there's a twisting moment on the plywood. So far, I've not had a problems but it definately doesn't give me any good feelings, neither. - I would not have made the outboard end of the cradle so deep; but rather about 4" below the main spar. Two reasons: 1) Makes taking the wing in and out a little easier since one doesn't have to lift it so high. 2) I riveted on my bottom skins with the wing in the cradle and I needed to be able to lift the skin out of the way. Things to look out for: - If you're installing the Duckworks leading edge landing lights, be sure that the overall length of the cradle won't position the cradle support where the light will be installed.

Subject: Vernatherm stuck open?
Folks, I think my Vernatherm is stuck in the open position allowing oil to always flow through the oil cooler. Here's the basis for my thinking: In October during some of my flights, I was seeing OAT's of 35 and 40 with corresponding OilT's of 174 and 179. In November during one flight I had OAT of 62 and OilT of 177 - I stopped and had lunch - during the flight home, I had OAT of 65 and OilT of 146. Yes plenty of time for it to have warmed up...and no, I didn't change anything on the airplane during lunch. All flights after that one have had OAT's in the 50's and 60's with OilT's not breaking 140. Your thoughts please... How do I unstick the Vernatherm? Is it possible that during lunch that day, my rings seated and my engine finished its break-in process?

Subject: Re: Vernatherm stuck open?
The Vernatherm doesn't work that way. It has an expanding salt/wax inside and expands with temperature until it closes the bypass opening. There are published dimensions, so you can remove the vernatherm, measure its length and see whether it is at the expanded dimension or cold dimension. You also could just create a cover for your oil cooler with say 50% as big an opening as the cooler itself, and see if it makes a difference, watching to see oil doesn't get too hot. Ralph E.

In addition to what David Nelson said about a wing cart: - Make sure your castering wheels are well attached to a robust structure. Mine were always falling off/breaking the wood because there is a lot of force acting through them. - I used ex-furniture casters which worked fine in the garage, but not on the more uneven driveway. - Make one end the shape of the wing rib and the other end flat, to support the main spar as it exits the wing. - Decide how you want the wings facing before you cut the shapes. Least space would be lower surfaces facing each other, but facing outwards lets you work through the access panels in the wings. - You don't actually need an outer frame if you use a relatively strong spine, like a 2X4 attached to a 2X6 but make it shorter than the distance from the landing lights to the inner wing. - I found foam strips, stapled in place around the curvature of the wing slot helped protect the wings.

Thanks for the idea Nelson, but my kit was prior to this mod for the nose wheel.

Always great to hear from Das Fed :>), but I already checked this and the leading edge tank to fuselage bolt is a AN4 so "NO JOY" here.

Can anyone provide the published dimensions - or point to the publication they are published in? I have some pubs - but don't know where to look...

I found a couple different measurements, but haven't found the specs yet cold: 3.800" hot:4.031" diff: 0.231 (3/16" = 0.1876") The Vernaterm should extend at least 0.160" Between 150 F and 185 F (the temperature stamped on the Vernatherm 85 C ). These are individual opinions or measurements..I'm still looking for something official. Ralph E.
