One of the companies I worked for would make jigs for testing critical fits of assemblies out of aluminum, and then have them anodized a dark red. It was great for finding the jigs, and you knew that if it was anodized red that it should be treated carefully as it was a precision measuring device. A number of them were stored on a windowsill in our lab, and they did fade over time on the side that faced the sun. Eventually we started rotating them so they would fade more evenly, but they did fade. Another consideration (sorry to drop this in so late in the discussion): Anodizing changes the surface properties of the material, and may change the mechanical properties as well. Not necessarily a problem in RV's where the panel isn't a structural component, but in the RV-4 at least, the panel is riveted in and forms a structural part of the fuselage. In that instance you might not want to modify it's properties. You don't say what kind of RV you're building. -Rob ________________________________ Message 5 _____________________________________ Time: 07:28:25 AM PST US From: "Evan and Megan Johnson" Subject: Re: RV-List: annodized instrument panel? --> RV-List message posted by: "Evan and Megan Johnson" I've been involved with building a couple of showplanes and the panels were done in a similar manner...only the laser cut through paint.

Maybe the average guy can do a 180 and not stall, but there is a lot more going on. First, the transition from power on climb attitude to power off glide attitude is HUGE. Having lost an engine in a C-120 climbing out of Meadowlark airport (closed now, Huntington Beach CA) I was surprised at how big that transition is. After getting the nose down it was very obvious that a 180 was out of the question. I turned 30 degrees left and landed in a plowed field. But here's the point, if you lose your engine after a normal takeoff roll and climbing to 500 feet, how much runway are you going to have left to land on after making this 180? Not much. Probably more ahead of you than behind. You can tell the guys, "Yep, I made a 180 back to the airport." Probably be best to leave out the part about running off the end of the runway. Now, put yourself in a Rocket or Pitts. If you are making that cool 3000 fpm climb and the engine decides to take a break there are altitudes at which it is impossible to get the nose down, establish a glide and land the airplane before hitting the ground, forget the 180 degree turn. If you just cut off that thrust vector, things happen fast. Anyway, just some more stuff to think about.

If you don't believe Rich, go out and try it, at altitude. Simulate a climbout just after takeoff, then chop the power. Wow. The more power you have, the more dramatic the difference, assuming a Vx type climb. -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive ________________________________ Message 11 ____________________________________ Time: 09:54:13 AM PST US From: "John Jessen" Subject: RE: RV-List: Minimum altitude to return to airport --> RV-List message posted by: "John Jessen" Energy management and relative wind is what it's all about, besides having the ability under extreme duress to figure it all out in time. For me, it'll be upset training in the future when I can afford it, just to better understand what all is going on. In the meantime, I will make sure I know what my straight ahead options are and prepare for that. I'm not yet skilled enough to even think about turning back given the scenario being discussed on this thread. A Navion that took off in full view of myself and a few others ran into this exact situation. Lost engine around 500'. Two souls on board. Great pilot. All kinds of hours and experience, but by the time he kicked into mental gear there was no runway left to put it down. He managed to turn it almost 180, but landed off airport in a nursery full of 3' high evergreen trees. If he hadn't been skilled enough to do this, the souls would probably have gone elsewhere, but as it turned out, he and his wife made it okay, after multiple bones being broken and a stay in the hospital. I've stood and looked at that end of the runway a great deal since then and have come to the conclusion I would not have made it. When flying out of White Plains, a check ride CFI asked what I would do if we lost power on take off. I told him my plan that day would be to go straight ahead, probably try to make the lake that was across a freeway and slightly to the left of the runway. He said he'd rather the freeway, which I thought rather selfish, given the traffic there would create more carnage. Neither one of us said turn back. I think that practicing such maneuvers is appropriate, at safe altitudes. Practicing glides, too. Practice it all. Practice. Practice. Practice. And when you take off have that engine out scenario and decision points firmly in mind...in terms of your ability and skill. Mine for now is straight ahead. Hopefully I'll be able to have a few other options as I become a more skilled pilot.

To give a little bit of background, I attended the "Fuel Injection 101" class given by Airflow Performance at their factory in Spartanburg, SC. I'm going to inject a personal opinion here. If you don't want to read about how much I enjoyed the FI-101 class, skip past this paragraph. :) The class is great and is, in my opinion, a tremendous resource. If you are considering installing FI in your plane and don't already have good knowledge about how fuel injection works (particularly if you are installing an Airflow or Bendix system!) I would very much recommend the class. Don Rivera teaches the bulk of the class (though you spend time with his technicians as well getting to run the fuel injection components on their diagnostic flow benches too!) and communicates both the theory and practice of fuel injection in a way that even *I* could understand. There is classroom time, hands-on lab time, hanger time, and social time. Don and Colleen are great hosts .. and API is a small friendly operation that really welcomes and educates folks at these classes. The class is enthusiastically recommended. If you have any other questions about my experience at the class last-weekend write me off-list as this is already starting to sound too much like an ad for API. Ok .... soapbox mode off .... other than to say I have NO affiliation with Airflow Performance other than as a customer and student. :) The easy location for installing the Floscan seems to be after the fuel controller, but before the purge valve (or the flow divider, if you don't use a purge valve). Regarding the recommendations to install the sensor with certain minimum amounts of straight line in front/behind the unit and the wires exiting strairht up ... my impression was that these constraints should be met for those situations where you need EXTREMELY precice flow measurements (like in a laboratory setting). For our applications that extreme level of precision isn't going to add any significant value. Ease of installation and servicing carries (for me, at least .. YMMV) more weight. Therefore, as long as there is some (even relatively minimal) straight section of tubing .. maybe even just a fittings-worth .. ahead of the Floscan it has proven to operate just fine. The folks at API have seen (and performend) a number of installations with these sorts of installation criteria and have not seen any problems with the operation of the units. I'll be installing mine as suggested ... after the fuel controller, and before my purge valve. -- Dwight On Sun Feb 26 22:49:27 2006, William Gill wrote : >Hello Dwight, > >Please post information on the list regarding the Floscan location after >your class. > >Best regards, ________________________________ Message 13 ____________________________________ Time: 11:10:20 AM PST US From: "Randy Lervold" Subject: Re: RV-List: Floscan and IO/360 --> RV-List message posted by: "Randy Lervold" > I'll be installing > mine as suggested ... after the fuel controller, and before my purge > valve. > -- Dwight Dwight, Was anything said in the class about the fact that if you mount the sensor this far downstream it will necessarily be mounted to the engine itself in some manner and therefore subjected to significant vibration and heat? The Floscan needs to be horizontal so that means it will likely be on top of the cylinders somewhere near the flow divider. I'll need to make a decision on where to mount mine in a few months. On my last RV I mounted it behind the firewall and it worked very well. Randy Lervold ________________________________ Message 14 ____________________________________ Time: 12:22:59 PM PST US From: Dwight Frye Subject: Re: RV-List: Floscan and IO/360 --> RV-List message posted by: Dwight Frye Randy, Those issues were brought up (by me, in fact). I'm always cautious about being conveying, second-hand, something someone else said. For that reason rather than start this off by saying "Don said" .. I'll couch it more in "what I understood was" type of language. There is always the possibility that I mis-understood (and I would be happy to be corrected) so if you have any concerns at all ... call API and ask them straight out. So ... what I understood was that while Floscan tends to specify optimal installation requirements (horizontal, wires facing up, with certain minimum amounts of straight lines leading into and out of the unit) that in practice there is a lot more flexibility in how they can be installed and still perform. My understanding is that they have been successfully installed vertically with a short straight fitting leading into the sensor and a 90-degree fitting leading immediately out hanging down between two cylinders. This seems to be in opposition to virtually ALL the requirements I have heard for Floscan installations .... but the units reportedly worked fine and gave good service. Note that the class didn't focus on issues like Floscan installation, and this was a side-discussion with Don because I was particularly interested in hearing what his experience had been with the units. I have been trying to decide if I need to arrange for the installation of the sensor now (which would require finding/making space in my cabin tunnel area as others have done), or if I can put it off until firewall-forward time. The approach suggested by API sure opens the door to a lot of flexibility ... though clearly if you accommodate the optimal install (horizontal, wires up, long runs fore/aft, etc.) then you CLEARLY can't be going wrong. I guess it is an issue of comfort level since there is disagreement about what is the minimum install requirements for the device. API has a lot of engine experience, but it could be argued that Floscan knows their product too. How to decide? Beats me. :) Don's real-world experience leads me to feel confident in his opinion. But if you've not met Don and heard what he has to say first-hand ... then I wouldn't blame you for coming to a totally different opinion.

Working with the EAA, it looks like we've succeeded. I've set up a Web site (well, it's the old Web site) with the basic information. We'll be taking reservations shortly and I'll be working with EAA to pull it off. The BBQ portion of this is still on and there'll be further details on that, too, in the weeks to come.

Not a typo.... twelve inch throat depth, 2 1/2" tall.... it's big. http://www.vincesrocket.com/Miscellaneous.htm more details here. It's a little dirty and blackened from age, but it isn't rusty or worn. There is minor surface rust on the handles, but it is of no detriment. With minor modification you could use this to squeeze RV spar rivets. As is, it will do whatever heavy duty jobs you can fit in its throat.

Dwight is correct in his assessment of the Flowscan installation. Although the reason we don't like to install the device on the suction side of the engine driven pump is the fact that the Flowscan has a fairly small hole going into the transducer. By having this restriction on the suction side of the engine driven fuel pump you are inviting possible vapor problems. I know a lot of people have done it this way(mounted the Flowscan in the cabin), but to me your rolling the dice. Also on carbureted installations you can get away with some installation issues that you can't with fuel injection. That said we have always mounted the Flowscan device after the fuel control (servo) and before the flow divider. We always install AN816-4-4D fittings in the inlet and outlet of the Flowscan. I have used a hose as short as 3" on the inlet side (all straight fittings) and a hose with a full flow 90 degree fitting on the outlet end. We have done some installations where the wires came out horizontal. These installations all worked fine. The Flowscan is never mounted directly to the engine, but hung between the hoses which are supported or supported to the engine mount with Adel clamps. The trick here is to keep the metered hose as short as possible. I have seen certified installations where the Flowscan was mounted directly to the outlet fitting on the engine driven pump or to the inlet fitting on the flow divider. I guess this works too but not my choice. I haven't had any issues with heat on the Flowscan, typically the transducer is protected with firesleeve after the installation is complete.

I really appreciate the info and discussion on this topic as I too believe there are no absolutes in this decision making process. I did most of my flight training in my own RV9 with a good friend of mine as instructor. He initially endlessly drilled into my head to always land straight ahead in event of power failure on T/O, but as training progressed he began to throw a few extra scenarios at me. The terrain in northern BC demands it. One little grass strip that we practiced on has a deep ravine at the end of the runway. Enough altitude and you can turn back or make it to the other side. Not enough and your best hope was to turn and try to crash along the bottom. Not very appealing. But allot of thought has gone into a particular strip that I used to fly out of (as a pax), when I was a hunting guide. 2000' grass with mountains on 3 sides and a glacial fed lake on the end. You always had to T/O over the lake regardless of wind direction. This lake is very remote so possibility of rescue from boaters is almost non-existent in case of a water landing. Help from anywhere out there is unlikely. (kinda like in the movie "The Edge"... lotsa grizz too!) Every trip I ever had out of there was in a fully loaded C172 that seemed to use every available inch of runway before we would struggle out over the lake for a few miles until we gained enough altitude to safely fly through a mountain pass. Turning back there was certainly not an option but all other alternatives were also extremely grim. Fortunately it has never been an issue. Time has been at a premium these last few years, preventing me from returning there but as I'm currently just finishing up my 5th and final year of tech school I expect to soon be resuming some of these activities, but this time with my own plane. As my RV9 has far greater climb rate and uses far less runway, I expect to have more options in case of emergency. Everytime I fly out of there I will be expecting that engine to fail and will include in my preflight the exact min. altitude required for a 180 back to the strip or as close to it as possible. If I keep my plane in top mechanical shape then hopefully it will never happen, but it is an experimental plane with an experimental engine, so by keeping myself in top physical and mental condition then god willing, I will have the strength and skill to accomplish something that I would never do at that perfect airport with a farmers field at the end of each runway (kinda like my home field :-). I have limited flight experience so I don't like to disagree with experienced voices such as Doug, but I feel that everyone that fly's in areas of rugged terrain should be aware of exactly how much altitude they require to make a 180 and be mentally prepared for it at all times to reduce the "oh s***" time lag, and the judgment to recognize that a straight in approach is still better for most cases. But it's not absolute. Todd Bartrim Turbo 13B RV-9 > It's a rehash.

They were well aware of the tendency of sunlight to fade the dies. They said that if I request it they could use an "architectural dye" which is much more stable. Apparently anodized colored aluminum is being used in architecture nowadays for decorative purposes. I think the architectural dye is much more resistant to fading, but probably not completely resistant. The sun is relentless. They suggested that a further protection would be to have the thing clear powder coated after it was anodized and laser engraved. I didn't even know there was such a thing as clear powder coat. Another suggestion was spray-on Krylon urethane clear coat. Since the plane will be hangared (assuming I can ever find a hangar in this town), the exposure to sunlight will be only during flying or parking at a distant airport. So, I'm leaning towards going ahead with this. -- Tom Sargent RV-6A, engine. ________________________________ Message 27 ____________________________________ Time: 08:07:50 PM PST US From: Fiveonepw@aol.com Subject: Re: RV-List: annodized instrument panel? --> RV-List message posted by: Fiveonepw@aol.com Consider that most of our "babies" are usually hangared- how many hours would your panel be exposed to direct sunlight after X number of years?

Is this really an issue? ========================================== Yes and it doesn't take long for it to look really bogus. This is a known problem with regard to anodizing dyes and IMO is a very strong argument for powder coating, as these finishes are very color stable. The only down side to powder coating is that it shouldn't be done where the corrosion resistance of a chromate is indicated or where structural cracking might go unnoticed.. Why would anyone knowingly color anodize something that will be outdoors when powder coating is so superior and readily available? GV (RV-6A N1GV O-360-A1A, C/S, Flying 776hrs, Silicon Valley, CA)
