The story of how I came up with it is pretty interesting. The first seed was planted when I was a 15 hr student pilot in a C-152 waaaayyyyy back in 2000. My instructor demonstrated how even with the mixture set for idle cutoff the engine could start and kill you. We shut the plane off by pulling the mixture. About 30 seconds later we spun the engine and it fired for about second then died. He explained to me that idle cutoff works by not actually shutting off the fuel, but by blocking the breather in the carb. Thats why the reaction isnt instantaneous while you are leaning. It takes a while for a vacuum to be pulled inside the part of the carb affected. About the same time I met a Lycoming rep at an event in Hartford called Safetyfest. He gave me a book containing all of the Lycoming operating and end user bulletins. I read it from cover to cover. Somewhere in the book it recommends running at slightly elevated rpms with the mixture leaned to clean off the plugs prior to shut down. Although strangely, the article didnt mention anything about shutdown. When I got my license and started flying the RV I noticed that if I leaned very aggressively while on the ground my plugs and oil filter stayed very clean. I leaned just very slightly short of roughness. I used this when taxiing out before a flight as well as after a flight. It is not a safety issue because when you do your run up, if you forget to enrich the mixture, the engine stumbles at about 1100 rpm. So Im taxiing in in the RV rolling these experiences in my head. My RV shakes more than most on shut down (conical mount). I realized that part of the shake is from the engine continuing to run intermittently on less than 4 cylinders as a vacuum is gradually pulled on the carb when the mixture is placed at idle cut off. Well, why not let the vacuum build up prior to actual shutdown?? When I reached my hangar, I ran the engine up to 1000 rpm or so and leaned it to just a slight bit of stumble. Left it there for 5 seconds and pulled quickly to idle cut off. Wow, no stumble, no shake.

The lead screw in the Ray Allen servo extends into the hole made for the manual trim, so that won't work. I am thinking of bypassing the horizontal stab and running it through the 4130 horn bracket directly to the back of the fuselage through some corrugated plastic armor and clamping it out of the way of any moving parts. The wiring I have for the feedback pot is 3 conductor shielded that is a little stiff, and I don't want it to have to bend too tight or over too short of a distance.

There weren't enough of us to form a class this time so I had to race against the fast glass retractables, canards, etc. I came in third at 216.1 mph behind a pair of Lancairs. Only .7 mph behind the 2nd place and beat a Glasair that came in 4th. Flew at 220 IAS but the high winds knocked the average down. Have not flutter tested above 220 but would have been tempted to use a little of my reserve power if I have known the 2nd place Lancair was that close. Tracy (not victorious but God!, was that fun!)

In my admittedly biased opinion: Most definitely, ask any Navy pilot that question. When escaping windshear / microburst conditions in aircarriers the flight director is driven by the AOA, it is the only way to be insured you are getting the maximum performance out of the aircraft~~same goes with any aircraft if the AOA is setup and indicating correctly. A 747 & an ultralight still rely on lift derived from the airfoil, an AOA is a useful safety device on both, and all in-between. I tell my customers to use the AOA as a reference to know what airspeed to fly. It is not feasible to have one change their flying habits since their first flight overnight. As one gets used to the AOA it becomes more and more in the scan, so that over time you are automatically at the correct airspeed for the conditions as dictated by the AOA without actually being aware of it. This is from comments from our customers. Remember the AOA is changing every time you move the flaps. In my opinion an AOA should give warnings, both audio and visually when below the "minimum safe" approach speed, well ahead of the stalling angle so it takes only a small change in attitude to be back "safe" again. Should you be distracted the audio warning will do this. You will be amazed at the difference in approach speeds between your aircraft loaded and at a light weight, 1/2 & full flaps etc. Accidents are not planned. Safety has always been a hard sell, however, did you ever know anyone who prior to flying said "I'm going to have an accident today?" Safety is no accident! Contact off list if questions.

I'm deciding which kind of trim system to incorporate for elevator; manual trim tab or servo trim tab, and aileron; manual springs or servo trim tab. My primary decision drivers are performance (in terms of light responsive controls) and simplicity (in terms of weight and overall system complexity). These two drivers seem to be at odds with one another, so a compromise is in order. Any good advice ?? Larry E.

If you had a Pitot-Static system failure that only impacted airspeed on your Dynon display, I imagine you'd still be able to fly cruise AOA's fairly easily, but approach AOA would be more difficult - due to being heads down. I think the biggest advantage of AOA is for a display failure and a heads up reference during approach. I'm planning using a Dynon as B/U for my EFIS/1, and also a PSS indicator on the glareshield. All 3 provide AOA. Mark Swaney F-1 Rocket (building slowly) From: "pcondon" Subject: RV-List: Dynon D-10 EFIS AOA Question --> RV-List message posted by: "pcondon" I am interested in the AOA feature on the Dynon but have reservations on the indicator that presents the AOA data. I have stopped by the other AOA purveyors and listened to the sales pitches. I guess I can swallow the physics of the indicator and what it claims to measure. What I can't see is the real case of flying by the AOA in the Dynon display. Has anyone really flew by AOA reference NOT airspeed ?? Is the Dynon small yellow, green & red bars really accurate enough to yield real enough data for "edge of stall" flying ??? The reason I ask this is the other vendors have a rather large display with graduations that seem more functional for actual flying by (that) reference. ________________________________ Message 19 ____________________________________ Time: 11:07:36 AM PST US Subject: RV-List: Re: AeroElectric-List: Automotive Spark Plugs From: czechsix@juno.com --> RV-List message posted by: czechsix@juno.com Guys, there's a thread going on the Aeroelectric list about automotive spark plugs used with electronic ignition systems.

People have done this and have discovered that the heat from the pitot can melt the tubing ... which causes some minor problems. :) The NylaFlow tubing is much easier to work with than aluminum and at some point it pays to change to nylon if only for routing behind the panel (or so it seems to me). It seems that the recommendation is to use some length of aluminum tubing from the pitot, and then transition to the NylaFlow at a later point. The question is how to best make this transition. I've seen a number of suggestions, but am wondering if the particular approach shown at http://www.openweave.org/RV7/question.php would work. My trial fitting (as you see) looks great. It is a nice tight fit. But, I wanted to check with the list to see if there was anything I was missing ... and to answer a few questions I had regarding this approach. Questions I have are ..... * With the aluminum and nylon both having the same OD, will it work to use the Nylo-Seal fitting with the aluminum in this manner? * If this will work, do I need to use any sealant (like EZLube) on any of the fittings? On the NylaFlow? On the aluminum? * I realize that if I use EZLube I should apply it to only the male threads/components. However, if it is used should it be applied to the small nylon bushing which is included with the Nylo-Seal as well as the threads? * Finally, it is my understanding that I should use the bushing on the NylaFlow tubing, but should I also use it on the aluminum tubing? Answers to these questions would be most appreciated. If you have any advice or experience in these matters please drop a note my way.

You can make your own. The hard part is making the 'egg crate' to separate the lamps (or LEDs) from each other. Go to a sign shop and get some 1/16" clear plastic and some glue. Find a Brother Label Maker (like a p-touch) and use clear lettering on black background ..... I think they have it that way. Put all the 'words' in one strip to determine how long your 'egg-crate' will be and the spacing for the dividers between the words. One or two spaces between words is sufficient. Paint the egg-crate flat black. Lay the lettered strip between a clear front panel and the egg-crate and mount the lamps any way you can. The LEDs will have a nice bezel that will mount in a hole .... just use another strip of plastic just like the front. All the other lights/holders will be large so I would recommend the LEDs. Check out the different colors you can get in LEDs too. There are many ways to do what you want ..... just brainstorm with a few Experimental friends .... we're creative and more so when we get together!!!

DELETE if you don't have a nose wheel; this couldn't possibly interest you, and you'll only be tempted to make disparaging comments about my sissy gear ;-) I evidently have the old Cleveland wheel on the front (If I were home right now I could establish this with 100% certainty by looking). This means I have a U-609 full-length aluminum axle and a pair of U-610 spacers (info gleaned from the RV List archives). The newer hardware includes the Matco wheel and a pair of stepped spacers without the axle. My bearings are both bad, and the replacements I have gotten from Van's are of a new type: Timken LM67000L-A, with the integral neoprene dust seal on the outside. Both new and old bearings use the old cup, Timken # LM67010, and I have these replacements as well (although, incredibly, Van's doesn't sell them, just the bearings). Problem: new bearing is wider than old one, so old washers and felt are too thick to fit inside the retaining ring that locks the bearing into the wheel. Potential solutions: remove neoprene, risk damage to bearing and defeat the anti-contamination feature. Buy new (matco)wheel and spacers. Find old bearing and live with the lack of dust seal (risks repeat bearing failure but is most attractive option at this point.) Problem: Timken part number is worn away on my old bearings; Van's no longer stocks them, and the builder's plans for the Cleveland nose wheel don't reference a part # for the bearing. My best hope seems to be wandering down to the auto parts store with old bearing in hand and looking pitiful at the counter guy; perhaps he can come up with a cross reference from the dimensions. I am, of course, hoping someone on the List has the old part # written down somewhere. I may end up having to tear the neoprene off of the LM67000L-A's and "going retro." Next chapter: I have the dreaded end-play in my gear leg; just a little, but it's there. Gus tells me there are lots of -A's flying like that, and the cures the factory has tried range from JB weld, to tack-welding, to oversize bolts and welded-on gusset/doublers. They were not enthusiastic about taper pins, which seem to me like an elegant potential fix... Unfortunately, the oversizing bolt options all started with, "First, you'll have to pull the engine for access..." Never mind. When the gear leg falls off, I will deal with it! -Bill B ________________________________ Message 30 ____________________________________ Time: 03:16:01 PM PST US From: "Joe Hine" Subject: RE: RV-List: trim: springs vrs tabs --> RV-List message posted by: "Joe Hine" Hi Larry and others I would agree with Sam.

Bill, are you talking about the play around the gear retention bolt which goes through the motor mount and gear leg? If so, there can be some relief had by putting in a close tolerance bolt (if it will go, obviously - if not, it might be worth having a machine shop turn a few tenths off from some bolts, rather than trying to get the gear hole bigger). I pulled my nose gear for a general inspection after about 350 hours, and it was a bugger getting the bolt out. The bolt gets worked a bit as the nose gear rotates back and forth. I might simply add replacing that bolt to my annual, to prevent it from getting so bad that it can't be removed.

I discovered quite by accident that 5/16 drill bits are typically tapered. The business end is about .002 inch bigger than the shank of the bit about halfway up. All the old bits I could find around here were that way. Some old machinists didn't believe me until they miked the bits themselves. When I drilled my gear legs I took one of these bits, cut it off in a grinder and resharpened it, and got a good fit to the bolts that came with my kit. Time will tell if this prevented the problem that you are having. Maybe it will help someone else. On getting bearings: There used to be a place called Bearings, Inc., but the name has changed, and I don't know what the new name is. But, they specialize in all types of bearings. You can take your old bearings to them and if the number is missing they will measure them and sell you replacements. Name brands. They were about 1/4 the cost of the certificated bearings from Spruce. I have no doubt that they are just as good.

There was a similar thread about two months ago. My suggestion was to run a couple feet of thin-wall stainless tubing from the heated pitot. Stainless is a crummy conductor. Anchor the stainless to a rib with an Adel clamp to help suck away some of the heat. A good way to bend thin wall stainless is to plug one end with wax or duct seal, fill the tube with water, then freeze it solid. (The freezer will do, but dry ice or LN2 is better.) You can bend is in a corkscrew and it won't collapse. This is also a good way to bend one tube inside another and have them stay concentric. ________________________________ Message 43 ____________________________________ Time: 06:39:42 PM PST US From: LeastDrag93066@aol.com Subject: RV-List: Lycoming 320 MT Propeller offer --> RV-List message posted by: LeastDrag93066@aol.com Hi All, I am making the following offer for new MT Propellers for the Lycoming 320 engine.

I am trying to find "the wall" where more power really does little in the way of more speed. Right now I cruise at 60% power, Alt 9500, and 160 knts TAS and 7.5 gal an hour. This seems to be kind of a sweet spot. Does any one else have any cruise data. Power settings Vs fuel flow Vs altitude etc. I am just looking for in the ball park figures. Scott Bilinski Eng dept 305 Phone (858) 657-2536 Pager (858) 502-5190 "Sweet spot" depends on the relative value you put on speed and fuel economy. My own sweet spot is at 152 kts (175 mph) at 12,500 ft burning 6.25 gph. Another sweet spot definition is the point on the HP required vs IAS airspeed curve of the aircraft that is tangent to a straight line drawn from the origin (lower left corner of graph). This point turns out to be at about 130 - 135 mph IAS on all RV types (3 - 6). This point does not change with altitude and illustrates the increased efficiency at higher altitudes since any given IAS is faster the higher you fly.

I need to correct the above post. It has been brought to my attention by someone who has every reason to know what he is talking about that AnywhereMap does *not* send all the NMEA data that is required for proper operation of the EZ-Pilot. I apologize for the incorrect response.

Placement on the left side is where I think Vans recommends. This placement provides an effective heat shield for the fuel hose but complicates attachment of the exhaust hangars to the engine case on that side. Is there any problem with placing the muff on the crossover pipe between port 4 and 3 (in front of the sump)? About the only issue I can see is a long run from the muff to the firewall. Another question has to do with keeping this thing from moving or rattling around. I understand there is some sort of high temperature cement that can be used on exhaust systems. Is this true?

I use the Carburetor heat on the front cross over pipe. The sump bolt I used was the second bolt inboard for the exhaust hanger and it worked fine. The pipe hangers is located just aft of the weld on the pipe aft of the heat muff. You said you was having trouble keeping the muff tight on the pipes. After putting the assembly together with the small rods and nuts using the hose clamps with the kit around the front and aft end of the muff it is held secure. The two half stainless pieces that come with the kit should be a perfect fit around the pipe. My system has been together for 300 hrs and is still very snug. I hope this helps.

My Navaid and Controlvision work fine together but Jerry Hansen at Trio (EZ Pilot) says the data stream from Controlvision lacks something essential so the EZ Pilot is not compatible with Controlvision's Anywhere Map at present. Jerry also emailed me today and said Trio met with Controlvision at Sun 'n Fun and Controlvision was going to send them beta software to test '...within two weeks' so it sounds like it's just a matter of time. Meanwhile another RV-9A builder here in Yuma who has an EZ Pilot in his hand is going up with me this weekend to compare the Navaid against the EZ Pilot. For this test we'll supply GPS data from a handheld for the EZ Pilot and from my Controlvision for the Navaid. The EZ Pilot plugs into the Navaid wiring harness so it will be easy to swap units. I'll post what we discover.
