The flap hinge is in the wrong place. I had the same situation on my QB-8. I called Van's and was basically told too bad. I ask they supply a wider hinge to use on the trailing edge, since it was their building error and was told I could buy it from them if I wanted it. I bought it from Wick's. I will also buy a lot other things from Wicks instead of Van's.

My Home Page ________________________________ Message 4 _____________________________________ Time: 07:45:04 AM PST US From: Wheeler North Subject: RV-List: Air/Fuel Inbalance --> RV-List message posted by: Wheeler North A few thoughts on this issue. If the carb is installed in the normal position the throttle lever is on the right side. This puts the pivot line of the throttle plate bisecting cylinders 1 & 2 from 3 & 4. I just checked all 12 MS carbs sitting in my cabinet and they are all designed to have the throttle shaft move CCW when facing the throttle lever to open. This means the Fwd edge of the throttle plate moves up and the Aft edge moves down. With the discharge nozzle directly below this, this should cause fuel to be pushed to the fwd side until the throttle plate is mostly open. Additionally the angle of the discharge nozzle would tend to also aggravate this. Since this does jive with the symptoms described, why don't all MS carbs have this problem? And, I'm not sure that they don't given that we have no way to determine if cylinder temperature variences are due to variences in cooling vs variences in mixture. Consequently, I have always thought this to be one of the weak aspects of carburetors, but have never really proved it causes problems universally. One interesting (but not easy) experiment would be to turn the carb around and see if the problem flipped. Another possibility is that something in the air filter is exacerbating the weakness of the carb. This problem may also go away as the temperature rises due to better vaporization. I don't remember if you said it was effected by carb heat or not? Also, is your oil temp up to snuff. The lycoming sump plays a big role in induction and vaporization. Also, my experience has been that drilling jets causes more problems than it solves unless you have a good machine shop to make a perfect hole. I would look to buying a larger jet before I drilled one of these. Another aspect of this is these "tubes" integrate the metering jet, the main and economizer airbleed jets and the discharge tube all into one unit. Drilling one of these may not take you towards the desired balance. I also don't see where making everything richer is going to fix the rear half without negatively impacting the front half.

The question has been whether or not I would be willing to seal tanks for builders who have already drilled and dimpled the parts.......essentially taken the tanks up to the point where the proseal comes into play. Well, I prefer to build the whole tank, but the answer is yes. I will work with you at whatever stage of building you have reached. There are a few airplanes like the rockets and the RV 3, that I do not have tank jigs for, so this is really the only viable option. I typically offer to build these projects on a time and materials basis. The labor from this point on is usually very close to the half way point in tank assembly. If you go to my website or call me, you can get the specifics for your particular model. It is important that you keep everything in order and label your parts so I can reassemble them. Please mark the left tank parts with a red sharpie pen and the right with green or black. The number 1 rib is the most inboard and so on. Also mark the fuel cap flange with an arrow pointing forward to the leading edge. The inspection plate reinforcing ring will also need a mark so I can get it back in the right orientation. Really the more notation you use the easier it will be to put the puzzle back together. To make sure you have included all of the hardware I will need, please download a parts list off of my website, or call and I will fax one. I will take care of the sealing and pressure checking from here.......I have built well over 200 sets of RV tanks to date. You can expect excellent workmanship and perfect seals. I do not make a mess of the sealant and I use only what I need to do the job properly. (think light weight). Feel free to email or call me any time with questions. Cheers.....

This has me thinking more pointedly about engine selections. I have questions, and want to tap the collective wisdom here. One question is regarding at what point in construction do I _need_ to have the engine in hand? For you smart-alecks, I do know I've got to have it before I fly (and before I fit the cowl, etc.). :) But what is the first point in the construction process where having it on hand is *really* useful (or even mandatory)? To set a baseline for the next questions, I'll say that I'm building an RV-7 and that I've already decided on 180HP, fuel injection, and CS prop. Which prop is still under consideration, however. :) The other questions I have are regarding various configuration options. I realize that there may be no "right answer" to these sorts of questions, but I'm going to ask 'em anyway. What is "better" ... horizontal or vertical induction? Dynafocal 1 or Dynafocal 2?

Does anyone have any ideas >on how one might make them red? Thanks. I'm not sure what type bulb is involved. You can buy red LED substitute bulbs for a very limited number of bulb styles. These would be the easiest fix if you are lucky. Here is a link to a company that has quite a few 12 volt LEDs with standard bases: http://www.americanbrightled.com/ >>>> Building your own LED substitute bulb <<<< It isn't that difficult to make your own LED bulb substitute. You use the base from an incandescent bulb, smash the bulb itself, then connect the LED and ballast resistor to the wires. Pot the wires in clear epoxy. Make sure that the short wire of the LED connects to the positive lead (usually the center) of the bulb base. Selecting the correct LED is not that difficult. First figure out what "viewing angle" you need. That is, how you want the light from the LED to spread out. Next, figure out how many candlepower you need. Put an "incident light" type photographic meter 1 ft away from the existing light and read the candlepower. Next, peruse the web www.Digikey.com, www.AmericanBrightLED.com, http://www.mpja.com/category/LEDs/LEDs.asp etc. for bright LEDs There are some mighty bright LEDs out there. You are very likely to be able to find a single LED that will put out the cone of light that you need. If you need a LOT of light, you can group and aim several LEDs. The ballast resistor for the typical 20 mA LED is 600 ohms, 1/4 watt (or greater). Put the ballast resistor in series with each LED. >>>>>>>>>>>> LED lights is what I know: http://www.killacycle.com/Lights.htm ________________________________ Message 21 ____________________________________ Time: 01:47:17 PM PST US From: Mickey Coggins Subject: Re: RV-List: Proseal instead of RTV on Van's static ports --> RV-List message posted by: Mickey Coggins Hi Mark, I used RTV to "glue" the rivets in there, but RTV would not stick to the plastic tube at all.

At least some of the decisions that you make about firewall forward components and their various positions will be effected by the engine mount and the engine itself. I found that mounting the engine to the engine mount then removing and replacing the assembled unit a few times gave me the best results. I hung the engine and mount from the ceiling on a chain come along and pushed the air frame back and forth for fitting sessions. Having at least a core engine with all the accessories you expect to utilizes in place would be helpful. Oil filter - yes or no, oil cooler, various hoses, electrical components, scat tubes, Fuel metering? etc.. It gets pretty busy back there. For instance the prop governor with it's control cable mount in place might have some small differences in size, control cable bracket position and profile shape that might be different. The choice of props therefore could have at least a small effect on your particular firewall layout. I used Vans firewall layout drawing and adjusted per personal preference. I lack experience with fuel injection, - No technical suggestions re induction. Getting rid of the lower intake snout on the cowl might be nice? The question of Dynafocal 1 or 2 might depend on which engine case you wind up with. Basically the Dynafocal 1 is Vans standard issue if you choose by from them. It could also be that Dynafocal 1 is all that is available in the Lycoming IO 360 series? - Nothing to offer as to D1 verses D2 I expect that Bart Lalonde at Aero Sport Power engines already on your list.

The trick is of course to use enough to seal the tank without having it build up unnecessarily and add a bunch (we are talking about pounds here guys) of weight. What you want to see is that perfect squidge around the ribs and baffle.You may be surprised at how much weight you can add with too much sealant. In a world or aircraft people who worry about the weight of the paint on their airframes, this is a big concern. I have found that most of the time builders use more than is really necessary. Your airplane I believe is an RV 6, and I typically use about 2/3 of a can of sealant on the pair. Please remember that I do this almost every day, so some of this is technique. I always tell my clients that it's not rocket science, but there is a learning curve. I would caution that in most cases it is better to use too much rather than too little. The best choice of all of course is just to send me your parts :) Evan http://www.evansaviationproducts.com/ (530)247-0375 (530)351-1776 cell ----- Original Message ----- From: "Sam Buchanan" Subject: Re: RV-List: fuel tank building > --> RV-List message posted by: Sam Buchanan > > Evan and Megan Johnson wrote: > > --> RV-List message posted by: "Evan and Megan Johnson" > > ....I have built well over 200 sets of RV tanks to date. > > You can expect excellent workmanship and perfect seals.

If you have a 160 horse, it should be burning about 14 gph at full throttle, sea level, full rich. If it is a 180, it should be around 16 gph. Somehow, you are not putting enough fuel in. Is the 11.2 at sea level or close?

I am not surprised at the 2/3 can per pair of tanks; seems I used between 2/3 and 3/4 can on my tanks. I have occasionally seen extreme amounts of sealer on tanks that I have inspected during the course of EAA Tech counselor visits. We even hear sometimes of a builder ordering *another* can of sealer from Vans! :-) Sam Buchanan >> >>Evan, how much sealer do you use for a set of tanks? >> >>Sam Buchanan >> >> ________________________________ Message 30 ____________________________________ Time: 04:38:09 PM PST US From: "J.

This has me thinking more pointedly about engine selections. I have questions, and want to tap the collective wisdom here. One question is regarding at what point in construction do I _need_ to have the engine in hand? For you smart-alecks, I do know I've got to have it before I fly (and before I fit the cowl, etc.). :) But what is the first point in the construction process where having it on hand is *really* useful (or even mandatory)? To set a baseline for the next questions, I'll say that I'm building an RV-7 and that I've already decided on 180HP, fuel injection, and CS prop. Which prop is still under consideration, however. :) The other questions I have are regarding various configuration options. I realize that there may be no "right answer" to these sorts of questions, but I'm going to ask 'em anyway. What is "better" ... horizontal or vertical induction? Dynafocal 1 or Dynafocal 2? And if folks have any input on various engine suppliers, I'm game to hear them (though I have been reading along here for years, and already have a bit of a feel for some of the favorite players).

GV (RV-6A N1GV, Flying 730hrs) From: "Brad Dement" Subject: E-MAG Order Dear E-MAG Customers: We are pleased to report nearing completion of the current batch of production ignitions. We regret that final assembly has been delayed by a few back-ordered components. As soon as they arrive units can be assembled, tested, and shipped. We appreciate your understanding and patience. In preparation of that day, we will be contacting customers with balances due to make sure that does not become an impediment to delivery. We have upgraded our sales/accounting software and altered our product ID references slightly. We will e-mail copies of current invoice and billing statements that reflect these changes. We ask that you look them over to make sure nothing has been omitted. If you have any questions please call (817 448 0555). As a reminder, some of you delayed final decisions on certain accessories, and we need you to finalize your selections now. Please note the following: 1. The cost of auto harnesses have been reduced slightly. This reflects a change in how these units are now offered. Instead of pre-terminated sets, they will come as assembly kits. This will permit a much cleaner customized installation, and will allow us to provide higher quality components. The kit includes a terminal crimping tool, high-performance spiral wound spark plug wire, high temperature silicone spark plug boots, etc. 2. A standardized shipping charge of $17 has been added. You also might like knowing that your ignition will incorporate a number of recent refinements. These changes are largely the result of customer feedback. We pay close attention to user comments, and hope you will be as generous as those who precede you. You are the beneficiary of their input. Please pass the favor along. 1. Mounting Clips (anodized to match the ignition) will be provided at no additional charge. 2. The overall ignition dimension is roughly 0.90 inches shorter than the earlier version of the P-MAG. This case size is now standard for the E-MAG as well as P-MAG models. 3. The coil style has been changed to permit a shorter electronic case section. With its flat base, this lighter coil will permit easier firewall mounting (if space limitations require you to do so). 4. The connector yoke is now a detachable 15 pin plug connector with a 4 wire pigtail. The forth wire (new) is a fully protected digital tack output. It replaces the tack signal that was previously piggy-backing on the kill lead. The mode selector switch is now located in the connector head. This will make changing the ignition operating mode much easier. Since the yoke now a separate assembly, if you decide (or discover) you need to firewall mount the coil, it is easier to provide a yoke with lengthened coil leads. 5. The MAP sensor hose connection is a now a single barb brass nipple located on the side of the ignition case. The size of the MAP sensor tubing has been enlarged slightly. 6. The installation manual has been expanded to include numerous tips and photographs. Note: The will be an ongoing evolution. Thank you again for allowing us to be a part of your project. Please don't hesitate to call if you have any questions.
