Billy, Have you considered a turbocharged Lycoming TIO-360? You can configure it to put out 230 bhp up to 20,000ft. This is the same bhp per cylinder as the certified Lycoming TIO-540 at 350 bhp. Above 6,000 ft you will have more power than a 260 bhp IO-540. It comes in close to, or less than, the weight of an IO-540. The extra space in the front of the cowl leaves room for a nice cooling plenum diffuser! The trade off is giving up 20-30 bhp on take off and then proportionally less up to 6,000ft. Or a turbo-normalized TIO-540 @ 260 bhp to 20,000ft. With this you could carry extra baggage all the time!

The Cirrus uses a 210 Continental IO-360 6 cyl that is de-rated to 200 hp. That is essentially what is in Van's #2 demo. The plane was designed to handle that engine, but there wasn't enough demand for Vans to produce a FWF kit for it. It is a heavier engine than the Lyc 4 cyl. IO360, but not by a lot, maybe 20-30 lbs. It does take some CG adjustment to switch between those two engines, as Cessna has done in the 172, where they produced T41 with the Continental, and the current 172 with the Lyc, and the early 172 with O-300 Cont 145 hp. Mooney's 201 vs 231 is similar, but the 231 has both heavier Cont engine and wt of turbo charger install up front, making it more nose heavy. On 10/14/06, Link McGarity wrote: > > 4 cyl eng in RV-10?

Okay, I am double cheating on this topic. I remember a post sometime back about where to begin on the plans if you have the quickbuild wings and fuse. Glassing in the tail fins almost finished. The VS front fairing was short and required addition to mate with rudder counterbalance arm. Looked in the archives and can't find it. Any recollection, anyone?????

I called and asked Vans about such a list. The answer was that they wanted the builder to have to read all of the plans as if it were a slow build. This is to educate the builder about how the whole thing is built. Seems like a reasonable idea, but I would still like to know just what has and what has not been done on my QB.

Call Vans again. I spoke with one of the girls (Jessica?) about some kind of flowchart that we were talking about on the list. She had an idea of what I meant and sent it out to me hardcopy (I have no scanner. It's a simple flowchart with all the sections in gray or white defining what the builder still has to do. Problem is, there are still portions of the QB stuff done in the Philippines that either was not completed or not completed correctly. So in short, yes you really should sit out with your plans beside your wings/fuse and go step by step. As agonizing as it is, at the end of three hours when you know exactly what you still have to do, you can realize that 3 hours of verifying is better than 3 or more months of monotonous building. They still leave the funner stuff for you to do, and it's still within the 51% spirit and letter of the law. Rob Wright #392 Buildus interruptus for sister's wedding...

John, Some day you will want or need to sell your -10. That will be when you find out how expensive "alternate" engines really cost. I am all for the concept of different engine choices (and applaud all who try) but one day you will have to convince a buyer to purchase your alternate choice and regardless of how nice you built the rest of the plane you should expect to shave $20-30K off a comparable plane while at the same time limiting the total number of buyers to ~20% of the original pool of prospects. (These numbers are HIGHLY scientific based on all recent -10 sales with alternate engines) When considering the additional time & expense it may take to get an alternate engine actually flying and that will far outweigh any potential savings. A note not covered on the recent discussion "RV7a v. Legacy FG v. Glassair SII FT" not mentioned when comparing each model and their respective traits is the significant increase in build time between the Vans kits and the other choices. Everyone concedes that the other choices are beautiful planes but I would prefer spending the extra 2000+ build hours actually flying.

Robin, this is out of context but where did you pull your statement "~20% of the original pool of prospects. (These numbers are HIGHLY scientific based on all recent -10 sales with alternate engines)"? I am not aware of one single flying alternate engine RV-10 except N210RV.

In the "For what it's worth" category, I happened to visit the Van's factory last Monday (and got a quick flight in N410RV), and bought the new WD-415-1's while I was there. They look much better than the originals that came with my kit, with a better weld along the back (where the original had its only weld) and a really beefy weld along the front side.

Genrally putting the battery on the firewall will shorten the life of a battery plus if you do put the battery on the firewall, you should consider creating an easy access to it's location...having the battery close to the starter may not be a bad thing as there is less line lose in the distance from the firewall to the starter as opposed to a location in the rear of the aircraft.

John, That was the humor part of the email thus the bold HIGHLY. As there are almost no -10 sales recorded and basically no alternate engines let alone sales of alternate engine -10's. My fundamental point is that if one wanted to go the alternate engine route for fuel / power plant savings that they would ultimately experience the "expense" an alternate engine costs at resale. I looked at a beautiful 7A slider with a Subaru engine mounted up front. It was as nice (panel & build) as the $110K 7's that have sold except the seller was having a hard time getting $70K for it. IMHO most prospective RV buyers were not willing to take the risk of owning an alternate engine especially when they don't have the experience of an alternate engine installation or are the holders of the planes repairman's certificate.

According to you guys, I probably have a version #2. I think I'll definitely order WD-415-1 OR the aluminum milled one. It sounds like the aluminum milled one is beefier, right? After all, the original is steel. John [quote="fehdxl(at)gmail.com"] v1: no aft weld (single weld across the front of the nut) v2: one long weld across the front of the nut and a small tack weld on the aft side of the nut v3: full width welds on both sides of the nut (Also known as WD-415-1).

Wow! I didn't mean to help start a firestorm, but the discussion has been very enlightening. Obviously, there are lots of trade-offs in the engine department. Frankly, I would be very happy with an IO-540, and will probably get one. The O-540 is a possiblility (I've noticed the hot start issue when I tag along with my brother and his RV formation buddies). My real concern is the availability of 100LL. It is my understanding that there are only two refineries left in the world that still produce it. What if 100LL becomes as hard to find as whale oil? Also, what are the issues with fuel tanks that were designed for - and only contain - 100LL? Obviously, there would be a run for autogas, and I assume that a way would be found to adapt an IO-540 to autogas. But autogas is a chemical soup that the industry and states feel free to alter on a whim. The real answer for our generation of flyers is diesel/jetA. That's all I'm looking for - a diesel 540 (g).

I fly behind an O-540 for a number of years and in flying behind the IO-540 also...the IO has occasionally a "re-start" problem if you try to start it in the cold start mode. The O 540 is almost bullet proof in starting. Lead additive...only one company makes the lead active for leaded gas and their plant is located in the UK. Most O-540 can use regular gas (leaded or unleaded) but if you think you're going to get an alcohol blended gas then you've got to make sure the pump's, lines etc will not be plasticized by the alcohol. Your fuel burn will be high with the alcohol as it's not delivering as many BTU's as pure gas. Diesel...not too many selections for aviation engines out there in large HP engines. Delta Hawk said they would create a larger engine after the successful introduction of the 4 cyclinder engine. I understand that they have finally begun delivering a few engines...my buddy Pete received his a week ago. But they are really 2-3 years behind where they said there were going to be...but at least they are in some sort of production. Guess you can see if SMA or Theilert can produce an engine in your time frame. P ________________________________________________________________________________

While removing the AN-3 bolts for the umteenth time that connect the elevators to the HS I slipped with the wrench and made a small tear in the skin of the elevator. It's about 1" long. I would like to repair it, rather than replace the entire skin. I thought I'd clean it up at epoxy a small square of aluminum to the underside of the tear and fill in the rest with filler. It's is not visible when the the elevator is in the trailing position. Thoughts? Jeff

Jeff, I would make the tear a square hole, then fabricate a small piece to exactly fill the hole, as well as a larger piece which would rivet to the existing skin as well as create the lip for the smaller piece to rivet to. Think of those repair kits used to fix a large hole in drywall. AC 43-13 has all kinds of good information about this regarding edge spacing, minimum number of rivets per square inch, etc, etc. Of course, if the tear is very close to the edge, on a curved part of the HS, or near a rib, the solutions become more complex. Hope this helps. -Jim On 10/16/06, jdalton77(at)comcast.net wrote: > > While removing the AN-3 bolts for the umteenth time that connect the > elevators to the HS I slipped with the wrench and made a small tear in the > skin of the elevator.

Give serious thought to reskinning that area. Elevator is a balanced control surface. So either you will have a small difference in counter weight on that side if you add metal for a patch, or not. The skin isn't that expensive, it is mostly the time involved. I tend to think you will be happier in the long run with fresh skin, but that is your decision.

If you choose to add any weight, be very careful when flight testing the airplane. The reason for balancing the control surfaces is to control flutter. There have been cases where the extra weight of adding paint to control surfaces caused them to flutter at high speeds. I would doubt that such a small piece of aluminum would cause the balance to change dramatically, but by the time you rivet it in place with a doubler to support it, you might add enough to cause a problem. Read Vaughn Askue's book "Flight Testing Homebuilt Aircraft" about how to conduct flutter testing. If it were me, I'd replace the skin before I would add weight to it.

Square patches indicate 90 degree corners and 90 degree corners equals stress risers. Try to avoid any sharp corners in that type of repair.

Or overhauling their own engine. Am I wrong or is there good reason to go with the factory new engine? I see any engine with crank made after 1996 as a minus, as most have AD, or have been replaced with new version, about little is known other than Lyc somehow changed specs, because the 1996 specs caused the original problem(or their forger, who knows).

Here is the write up I put in Van's Airforce with a couple shot. Saturday was a great day all around. The winds were 0-3 knots, 60 degrees OAT, and I didn't sleep one wink that night. I know everyone says don't have alot of people come to the first flight but that is one rule that I didn't follow. I let everyone know that wanted to know but it was still mostly my family and my wife's family. There were the usual airport groupies that were hanging around and two of my best friends from work were there too. I did a preflight on the plane early that morning and then Ray did one too. My friend Mark Patey came up from Spanish Fork airport in his RV-6A to fly chase and we went through the flight on the ground first. I was going to climb out (4230ft airport elevation) to 6500 ft. and orbit the airport below Class B. I wasn't going to touch the power settings until at least 6000 ft. There have been many engines that have quit when people started to pull back RPM's or MP. I was then going to fly 65% to 75% power for at least 20 minutes, then go into some slow flight and get some airspeed numbers. Then back to full power for 10 more minutes and land. I walked the plane one more time, made sure I had my POH (Thanks Tim) and my notes that I had made and strapped in. I did mount a camera in the plane. My friend's wife walked into the hanger as I was duct taping the tripod to the floor. I think she thought I was putting in the last few critical pieces. By the way, we will be putting the duct tape on e-bay from the first flight. The video is awesome from inside, can't wait to get it edited so everyone can see it. You can see the camera in the back in some pictures. My wife took a camera and flew with Mark in the chase aircraft and again some of the formation video turned out great. Because there was really no wind and my hanger is on the south end of the airport we had to make some calls and reverse the pattern. I did not want to taxi my new engine all the way to the other end and everyone was really nice about it. We then both taxied out to the end of 34 and I did my final checks. So there I was sitting at the end of the runway ready to take off. This is the moment we all think about over and over again after long nights of deburring, riveting, wiring, sanding, painting, troubleshooting, and day dreaming at work. I've always thought that I would get to end of runway, take a big breath and really take it all in. Well, I got out there and I was ready, the plane was ready and I just wanted to fly. I added one notch of flaps, turn the fuel pump on, checked for the 10th time that the fuel was on and all instruments were set and made the announcement, "OK, here we go!" The next few moments were very routine thanks to Mike Seager and 410RV. I went up and flew 8.5 hours in 410RV and had 44 landings with Mike. Everything felt identical in this takeoff. The plane accelerated quickly, I pulled the nose off within the first 200 feet and just held it up and we were airborne before the first exit. I am going to go out there someday and measure it because it seemed shorter than 500 ft. The RPM's were right around 2710 on climb out, I actually pulled them back to 2650 on my down wind and then back to 2500 at 6000 ft. It was great to have a chase plane there for the 30 minute flight. I didn't have to make any radio calls, I monitored the airport frequency but left it on 123.45 and talked with the ground and with Mark in the chase plane. I was able to focus on the flying and monitoring engine parameters. During the flight my airspeed seemed to be 5-6 knots slower at 140 knots than Marks RV-6A, and at 100 knots seemed to be around 4-5 knots. My CHT maxed at 410 on climb out and then cooled and stabilized at 385 F with 75% power. My oil temp never went above 185 F. The engine ran flawless (Great job Aerosport). I made one more upwind leg and started to slow her down to 85 knots for the first notch of flaps. Then I set up for a 78 knot decent and added the second notch (20 degrees). I didn't add full flaps because with only one or two people in the plane you can't trim out all the control forces with 30 degrees of flaps. Even with 50 lbs in the baggage, Mike Seager and I couldn't fully trim out the forces. So I decided during my transition training that 20 degrees would be my setting and it worked perfect. I was definitely fast on my approach but I had plenty of runway to bleed off speed. I planned on aiming for 1/3 down the runway and a couple extra knots over 76. 76 (90 mph) was the approach speed Mike Seager teaches you. My brother has some great shots of the landing sequence. I'll just include a few. Once the smoke came off that first wheel it was time to relax and celebrate. Now I need to fly off another 24 hours and then another 25 of rides but that is the fun part. I would definitely recommend some transition training for your first flight. When I initially called for insurance they quoted me 10 hours of total RV time with one hour in an RV-10. They apparently are now requiring 10 hours of RV-10 time! I have argued with them that this is going to be impossible for the whole RV-10 community to get but that is what they said. They allowed my training to count but start calling your insurance now and check on that. Also, having a chase plane was nice to relieve stress and to keep an eye on the outside of the plane.

Just for some data points can you share the following info: 1) What is the current engine config. 2) What is the current expected HP. 3) When did you order, when were you supposed to receive it, when are you know told you will receive it. 4) Are you anticipating any major challenges with the install. 5) When are they expecting to have the James Cowl ready. I haven't been keeping track since I went with my Barrett engine so I don't know the status and there was nothing on display at Airventure. Items 1, 2, & 3, above were directly related to my decision to go with a Lyc and I'm curious on if they are still shifting. I also think they are important things for prospects to know until there are a few out there for hard data. I used to live and work in the Chicagoland area and would love to drop in some time after you get the engine and see how it goes.

The real issue here is whether or not you really need a brand new engine. if you fly say 100 hours per annum it takes you 20 years to reach the 2000 hours TBO. Already there engines that are specified as 2000hours or 12 years what ever comes first. There ought to be 540's about that suffer from the crank issue and have been set aside or otherwise. Try these engines and buy the crankkit from Lycoming for qualified engines for $2000, it comes with all hardware and gaskets. This will give you in effect a 0 hour bottom end, then purchase a set of overhauled studs if the valves are good and built them onto your overhauled studs and you'll have an engine as good as new for a lot less and a bit of elbow grease. The scenario above can be achieved for core value or even lower maybe plus $5000. Marcel ________________________________________________________________________________

Kelly, there are options w/ AeroSport or BPA/Mattituck or the other 'authorized Lyc builders' I believe that Tim's engine was and Overhauled engine from Aerosport. By overhauled I think the only parts not new were the case and the crank. Another option (the one I'm using w/ BPA) is the Lyc 'experimental kit', where Lyc shipped all New parts to the builder (my understanding is that these are the same parts as the certified engine) and the builder assembles the engine and puts their name plate (experimental) on it. Going this route still provides savings over the Factory New Lycoming price. Additionally, with one of the kit builders, you are able to have your engine 'blueprinted' and somewhat customized (as John Cox would say 'hot rodded') like Allen outlined in his earlier post.

Cores are REALLY scarce, and demand premium price to purchase. The cores that are available were bottom of the barrel engine cores as little as 5 years ago. Every part that rejects on an engine core adds to the cost of an overhaul somewhere, be it your engine or the engine the parts came from to build yours, or new. This IMHO is the reason for the IO-540 kit engine. Lycoming quickly acknowledged the drying up of the 0/IO-540 engine core market and delivered the kit option first. No doubt ECI and Superior are not too far behind. Sure, this is good news for the end user as it spurs competition as do the alternate engine(s). This is a GREAT situation for GA to be in if looking at it from a purely economic standpoint.

Where the engine has been used in the past has no relevance to the FAA. If it has a valid data plate, and all airworthy parts, it is a certified engine.

If you have the piece with the data plate...usually sump on Lycs, any A&P can build the rest of the engine out of new PMA parts or Lyc parts, and sign it off as a freshly overhauled certified engine.

Agreed Kelly. The key thing to do is record ALL AND ANY maintenance done to the engine, in the appropriate fashion, in the log book. And it will have to be done to conformed status. In other words, CYA and there should be no issue. But, the maintenance will have to be done by a person with a powerplant rating in order to return the engine to certified category. This goes against one of the reasons in building an airplane anyway which is the freedom to perform your own maintenance, right?

Is #2 demo aircraft an anemic performer? Is only 800-1000fpm an anemic climb? There are plenty of certified planes that don't do as well at full gross, sporting "only" 200 hp, or less. From the Comanche 180, Mooney M20C 180hp, to the Mooney 201 that goes almost as fast as a -10 on less gas and "only" 200 hp. I don't think it is considered anemic. Has a gross wt of 2740 lbs for most versions, with a few that were increased to 2900. Not everyone needs to go up at 1500ft a minute. The 201 has service ceiling around 18000 ft, which most consider adequate for a non-turbo aircraft. No, it won't handle the short fields a -10 will, but as others have said, that depends entirely on your mission requirements. Will the IO-540 produce 150hp on under 11gph? I kind of doubt it. The IO-360 definitely will and does every day. Will the -10 do 165kts on that hp? At gross wt? John W. Cox wrote: > > A reduction of 260 to 210 is a 19.2% reduction in BHP.

IMHO I do not see any reason for 2 stands with QB wings. All of the top skins are already riveted in place, so you have little need to access that side.

Let me respond right here that the disgusting phrase "Hot Rodding" that I have used in the past is a tongue in cheek mumble that VAN regularly uses and for the benefit of Ken Scott who lurks on this list and tattles on all who modify this great aircraft. I have a lot of respect for Randy who built a "By the book, no deviation allowed" RV-10. However, I encourage and support those who modify this great basic entry cruiser aircraft into what it deserves to become. The most prolific and popular 4 place kit built aircraft on the planet. I am a proponent of multi-screen glass efis, higher compression pistons, improved induction, improved cooling, improved exhaust, improved cowling, improved braking, improved aesthetics, improved graphics and improved composite work. The phrase that builders would fall out of the sky or suffer catastrophic control flutter by making such logical improvements was from the editor of the RVator. I don't buy it, I have the same passion that VAN did when he Hot Rodded the Playboy into his first RV. I have 283 ideas (and growing) for improving this great design. Many of those are being incorporated with aircraft builders willing to move off the "plans only" construction concept. Don't get me wrong, I respect those of you who do not deviate.

Subject: Re: engines
Flutter and dynamic divergence are REAL issues every airframe designer (and for that matter, pilot) has to deal with especially so for higher-performance aircraft. There are two ways to set Vne in FAR Part 23. One, do ground vibration tests to find resonant frequencies (mainly shake the crap out of it and see if anything falls off) of the airframe, then go out and flight test to find its flutter point, then set the Vne at few per cent below this speed. The other is to use the canned Vne minimum speed formula based on wing loading. The canned formula is based on statistics from certified aircraft that if you set Vne at this speed or below, you won't encounter flutter. I suspect Van's took the conservative approach and set Vne based on the canned formula. Now as Van points out, weight affects flutter. Balance of control surfaces affect flutter (see Steve Whitman's crash several years ago), and horsepower available affects flutter. Most low-power spam-cans don't have the power to ever approach Vne except in steep dives, while adding power means the top speed capable (that point where the power available curve crosses the power required for level flight curve) creeps ever closer to the flutter point. Now, don't get me wrong, if someone want to drop in a 300hp engine into an RV, they are more than welcome to do it. However, they should get a professional test pilot to verify the Vne and flutter point for the configuration or get training on how to react when flutter happens (the time from flutter onset to complete divergence can be REAL small). Understanding the full ramifications of modifications to the original design and testing for it may save someone's life in the end. JKH On 10/18/06, John W.

Somebody from Embry-Riddle Florida once (4-5 years ago?) posted a cogent argument that still air range is pretty much independent of altitude and dependent only on power setting. I've lost the reference, but I did a crude thermodynamic analysis and sure enough, got the same result. I'm way too lazy to repeat the analysis unless forced. What altitude gets you is more speed at the same range. John Ackerman ________________________________________________________________________________

Assumptions: Vne is based on IAS, and for the -10 is 200kts @ 5000'. Vne is adjusted by 1.5% for each 1000ft of alt. At 20000ft, Vne is therefore 15(000)*1.5% less than 200kts (ie 155kts Indicated) Check out the attached photo from a turbocharged -10 operating here in Oz. Yes that is 152 kts at 20120' (Note the TAS in the bottom left corner and yes, they are knots!) If published Vne is 200kts at sea level, Vne @ 20000' is close to 140kts (70% of 200kts) If published Vne is 200kts at 8000', Vne @ 20000' is close to 164kts (82% of 200kts) Fast - yes, but a bit too close to the edge for this little black duck!

Not likely, unless you're already near your aft CG limit already, or some other unrelated factor comes into play. But, you should compute operating weight CG for each and every flight, including at takeoff and predicted landing fuel loads. And, you should determine, somehow, the mean fuselage station for extra compartments such as you describe, and the weight at such station. The Garmin GPS x96 series have an excellent weight and balance capability for such a computation that takes seconds to compute. I have a neighbor that once owned an RV-6, and just could not get the landings down. Enter another neighbor, high time experimental driver and tail dragger type (and also ex F16/F4 driver) and he could not get it either. Go to weigh the airplane and it's 70+ pounds at the tail while my RV6 is 52. That's a BIG difference in moment-arm for just 18 lbs, because it's so far away fm the 0 station, if you will. Go figure. Your extra compartment is a great idea, but it also has the longest arm of any station where the weight varies. The 70+ lb tail was not reflected in the prior owner's Wt & Bal computations, EOW CG to be exact. Did somebody just decide to make the tail somehow heavier, beefier, etc.? Who knows? Nothing was obvious. The point is that with experimentals, the FAA has given the owner or builder much more latitude to hang themselves. This discussion applies to any mods that deviate fm the kit manufacturer's plans. I'm not without sense of humor, or ability to be sarcastic, to say the least, but I also appreciate the apparent background and knowledge of many of the posters to this type forums. I've been flying professionally since 1979, and at this point I'm really into experimental flying for education and enjoyment. Others?

Niko you'll get 10-40% more range depending upon altitude, additionally with less oxygen you cannot burn as much fuel at altitude so your power goes down but you're moving faster because the air is "thinner"...if you could get to up upper levels it gets even better. That's why jets use a lot of fuel getting to altitude but use very little fuel at altitude. To get to higher altitudes you need one of several engine types: rocket, jet or turbo/turbine types. With normal aspiration you can only get so high before you run our of "air". Mooney created a sort of mini charge at one time by a small recirculation unit that would give you about an other 1"+ of boost on MP. Maybe Kelly could tell us how they did this and if one could use that in an experimental engine to give you a little more boost with out the need for a tubro, waste gate, fans etc. Patrick ________________________________________________________________________________

OK. You could probably jack the tail up, but not by yourself. After the mains start to leave the ground (and they will because you will not get enough compression), the fuselage becomes very unsteady and wants to roll. If you had more people to watch and steady the fuselage, go for it. It still takes alot of force to compress the elastomers. The full weight of the aircraft is not there yet, i.e., wings, tail, engine, etc...

I was at the Cherokee Pilots Assoc fly-in a few years back and talked to Karl Bergey, one of the lead engineers at Piper during the late 60s early 70s. Anyway, I asked why the Vne was different between the Archer and Warrior because as far as I knew there wasn't any difference between the airframes. Expecting to hear "Well we beefed up this or that, extended the HS by 1 inch, etc" I was surprised instead to hear that Vne was calculated (at least at Piper) solely by the dive test during certification. Whatever the testpilot felt comfortable taking the plane up to in the dive, subtract 20% and you had Vne. The only reason the Warrior and Archer have different Vne is because the testpilot flying the Archer went faster in the dive. I wouldn't be surprised if this is how Vans calculates theirs as well. -Brian #40497 Iowa City, IA -----Original Message----- From: owner-rv10-list-server(at)matronics.com [mailto:owner-rv10-list-server(at)matronics.com]On Behalf Of James K Hovis Sent: Thursday, 19 October 2006 2:13 AM To: rv10-list(at)matronics.com Subject: Re: RV10-List: Re: engines Flutter and dynamic divergence are REAL issues every airframe designer (and for that matter, pilot) has to deal with especially so for higher-performance aircraft.

The canned formula is based on statistics from certified aircraft that if you set Vne at this speed or below, you won't encounter flutter. I suspect Van's took the conservative approach and set Vne based on the canned formula. Now as Van points out, weight affects flutter.

Most low-power spam-cans don't have the power to ever approach Vne except in steep dives, while adding power means the top speed capable (that point where the power available curve crosses the power required for level flight curve) creeps ever closer to the flutter point. Now, don't get me wrong, if someone want to drop in a 300hp engine into an RV, they are more than welcome to do it. However, they should get a professional test pilot to verify the Vne and flutter point for the configuration or get training on how to react when flutter happens (the time from flutter onset to complete divergence can be REAL small).

2 'C' clamps over the elastomers...one on the px side and one on the drivers side. Put some tape over the powdercoat (like I did) and you won't even scratch it!

After the mains start to leave the ground (and they will because you will not get enough compression), the fuselage becomes very unsteady and wants to roll.

Hello Brian, I don't think Van's does it this way, they most probably go along with FAR 23.1505 and calculate this speeds, similar to certified airplanes (at least how it is certified today). It's a function of several parameters so you get your flight envelope (see FAR 23.333) and have your limitations set FAR (23.335). Even kit planes are made today with some since background. br Werner Brian Douglas wrote: > > I was at the Cherokee Pilots Assoc fly-in a few years back and talked > to Karl Bergey, one of the lead engineers at Piper during the late 60s > early 70s.

Subject: Re: Vne and flutter (was engines)
For each RV-3, a flutter test to 10% above Vne was recommended by Van's aircraft. I read a little bit about this before my flight test. In an attempt to simplify from what I have read: The Vne is an airspeed based on analysis and design. This is an indicated airspeed (IAS), or Part 23 calls this an equivalent airspeed (EAS). The EAS being an IAS that uses a calibrated instrument with a corrected pitot/static system. Flutter speed will vary from one aircraft to another of the same design. Although it is easy to identify when you've reached flutter speed, because major components SUDDENLY separate from the rest of the aircraft. The flutter speed is a true airspeed (TAS). Flutter speed is a variable number, because the actual construction and alignment of the aircraft WILL change this number. Especially sensitive are the hinged weight and balance of the flight controls. Given that Vne is less than the flutter speed at sea level; IF the IAS of Vne can be maintained with altitude, at some altitude Vne WILL exceed the flutter speed. (This is a bad thing.) Reading between the lines, here is what I am hearing Van's Aircraft say: With the Lyc. 540 engine of 260 horsepower, in level flight the IAS will not exceed the flutter speed of the aircraft. (Most flight time will be below 12,500'. Very seldom will a flight occur near 18,000'.) With a turbo normalized Lyc. 540 engine (or an engine with more than 260 horsepower) in level flight at some higher altitude, the IAS could exceed the flutter speed. And will exceed the flutter speed, if the IAS is allowed to increase at the start of a descent from a high enough cruise altitude. (Flutter is a high frequency thing, which we humans don't feel very well. Major component separation is a low frequency occurrence, which we would feel. :-) ) Regards, Jim Ayers RV-3 sn 50 In a message dated 10/19/2006 7:11:44 AM Pacific Daylight Time, bsponcil(at)belinblank.org writes: I was at the Cherokee Pilots Assoc fly-in a few years back and talked to Karl Bergey, one of the lead engineers at Piper during the late 60s early 70s.

Chris, I opted for dual LSE Plasma IIIs and have dual alternators and electrical busses. The point that Tim makes is a valid one - the wiring from the crank sensor must be very well routed/secured. With the dual system there's a pair of cables but they are running together. I suppose one could route one down each side of the engine to provide isolation in case of some sort of mechanical event that damage them.

Before you decide you might talk to some larger players in the engine building business like BPE.

As an aside I have the Lazar on my mooney and have not had a problem. There is supposed to be a new system coming out this next year that is superior to these 2 according to BPE. Good luck!

One last (probably not) consideration for you aside from the redundancy issues. When I was looking at the Lightspeed options, I talked to Klaus and he indicated about 90% of the performance advantages are obtained with the first system and there is a limited performance increase by using dual electronic ignition systems. Since I had not already put in the dual alternator/battery setup I opted for a Lightspeed/standard mag setup. My only backup battery is in the Dynon EFIS I use as the standby instrument.

Subject: Re: Vne and flutter (was engines)
I am not an expert, but Vans seems to be very conservative when it comes to such issues as specifications, Vne, etc. It would not surprise me if there is some wiggle room. Alas, I would feel more comfortable with a ballistic parachute if I were to try to exceed Vne on a semi-regular basis. An airplane, even an RV-10, is replaceable---you are not. I have a 325hp engine of in my aircraft, which is really only the 260hp engine fine-tuned a little bit better. I have not flown the 260hp engine, but from what I have observed in flight, the difference in performance seems to be very small. A turbo at high altitude, however, might make a real difference. of course, you then need oxygen, too. It becomes a much more complex (and potentially pilot-exhausting) exercise. with a parachute, this could be a nice thing to do, so. PS: n325hp is still for sale, now at the reduced price of $209,000. regards, /iaw ________________________________________________________________________________

Partly due too low engine temperatures and partly due to there not being enough fuel to get a good even fuel./ air mixture for efficient combustion. So from a practica l point of view, for maximum range, you set the minimum power thats advisab le to operate the engine at which in turn sets your fuel burn. So in the R V10 case I believe that for max range your power setting turns out to be th e same for all altitudes which is say around 45 to 50%.

Please allow me to chime in on this issue. Last week while preparing for takeoff in a friends Cirrus SR22, we began to see and smell smoke in the cockpit. Within only a couple of seconds, we had a face full of electrical smoke. We quickly shut off both the batteries and alternators and opened the doors and began coughing. It turned out the culprit was a "number two battery control relay circuit board" which is located in the cockpit that fried. Guess what.... the engine kept running Although my 10 will have a dual electrical system, with dual alternators, it certainly will have at least one mag! You just don't have enough time to troubleshoot and isolate electrical problems when the smoke starts, especially when you can't see or breath.

Chris, Interesting! Taking a little different tack, will your panel be all electric? I still think a vacuum backup is a good idea when the smoke starts to escape from the boxes. As you say, there's no time to troubleshoot when you can't see or breath. No mattter how much electrical redundancy you have, your only choice is to shut it all down when you suspect fire of electrical origin. This may be heresy to this group.

John, Don't tell me that you have been drinking the GAMI kool-aid. Since 1998 when I first acquired the Cardinal, GAMI has been touting PRISM and bad mouthing every other competitor product (FADEC, Lightspeed, LASAR, etc). Almost ten years later, they still don't have a product. I'll wager that in 2010 PRISM will still NOT be available. If and when it does become available it will NOT be cost competitive and the performance gain will be marginal-if any. As for their balanced injectors, they are a waste of money for Lycoming engines-even if you plan to run LOP. The tolerances on the stock Lycoming injectors are much better now. In 2004 I had a Factory Reman IO-360 installed and Im able to run smooth significantly LOP with the stock injectors. It's always funny to see those owners who insist on GAMI injectors for their Lycoming engines that have no intention to run LOP. BIG waste of money. Those Advanced Pilot Seminars are ensuring a loyal following of kool-aid drinkers and a constant revenue stream to GAMI. Personally, I plan to go with one Lightspeed and one mag.

Subject: Re: RE: Dual Lightspeed?
Well, you know what happens when you make universal statements. I know lots of IO-360s that won't run LOP, some that will, with stock injectors, my own included. However the TSIO540 used in the Mooney TLS/Bravo flat will not run LOP on the vast majority of those engines. It, by the way is a parallel valve 540, a distant cousin to what most folks are putting in the RV10. With GAMIs and an otherwise healthy engine, it will run LOP, up to certain power/TIT limits, but generally will not generate 75% LOP within those temp limits. While I can go to 70 LOP or so with my IO-360, I am certain it would run smoother LOP with GAMIs than it does without. Sounds like you have been drinking the factory Kool-Aid. TCM offers the same flavor Kool-Aid, and a few of their tuned intake engines are okay LOP but virtually all can have tighter mixture spreads. What the OEMs seem to miss, is that it isn't having identical injectors that is the goal, it is having all cylinders reach peak EGT at as close to the same fuel flow as possible, and unless all cylinders flow identical amounts of air through the power range, you won't achieve that with identical flowing injectors.

This is an excerpt from the Latest RV Builder's Hotline (October 21st) that I encourage all of you to read, study and begin meaningful discussion. That is the value of Matt's site isn't it. As a Designated Pilot Examiner for 23 years and an Accident Safety Specialist for 16 of those, this issue is real and is well reported. A theory that Average Rich Guy can buy a Hot Rod kitbuilt or recent TC certified aircraft then rapidly skew the statistical pool. The resultant statistical skew lends merit on the need for intensive and repetitive, tailored instruction from "Make and Model" qualified Instructors. To ignore such a pursuit, can tilt insurance costs the direction of wiping out a large percentage of the kit building community - before they are finished. The leading article is "A look at RV accident information" by Bob Collins. Thanks Simon, in my haste I figured it was stuff I could just gloss over.

Hi James, Stick with the standard M22759/16 Tefzel wire...don't bother with teflon, silver plated, etc...or surplus stuff (you never know what you're getting). Also, if you spend more than a few hours "hunting" for a deal, you've just wasted enough time to buy what you want and what you need brand new. Depending on what you're doing with the plane and panel, buy at least the following initially: 200' AWG22 200' AWG18 150' AWG16 50' AWG20 50' AWG14 25' AWG12 25' AWG10 100' RG-400 Coax a dozen male BNC's, a half dozen female BNC's, a couple hundred PIDG ring terminals, and some heatshrink. Now, depending on if you want colors or not you can split all that up. The above wiring amounts could vary pretty significantly depending on if you're wiring your own panel or not, whether you're going full boat on lighting, radios, IFR/VFR, etc.. I wouldn't waste my time buying whole spools then trying to sell the surplus. Heck, wire is relatively cheap, we're talking about something that costs pennies per foot...you'll only spend a couple/few hundred bucks of wire total. Why waste your time goofing around.......figure out what you need, what colors you want and just buy it. As someone who regularly buys wire in 10,000' - 20,000' spools and keeps over a half million feet of wire "hanging around", I can tell you playing with spools to save a few percent is a waste of time on an item like this, for one airplane. With your Avionics or engine it's a different story because you can save a lot of dough, but in the wiring it's such a cheap item to begin with that it's not worth much effort to save a buck. Just my 2 cents as usual! Cheers, Stein. -----Original Message----- From: owner-rv10-list-server(at)matronics.com [mailto:owner-rv10-list-server(at)matronics.com]On Behalf Of James Hein Sent: Saturday, October 21, 2006 7:32 PM Subject: RV10-List: What Wire for Wiring?

List was about the same length, and equal distribution of injuries, i.e. none/minor/serious/fatal. Saw NO RV-10's, yet. Only did cursory look at data, but food for thought. I hear that Cirrus is now requiring time in type to turn the new owner loose? Or would that be the insurance cos? RV-10 insurers?

Hi I have been reading the archives regarding torque wrenches. Section 5 of the builder's manual refers to torque specifications from 20 - 1500 in-lbs for AN bolts AN3 - AN10. My empennage kit only has AN3 & 4 bolds which implies all I need for now is a wrench that will do 20 - 70 in-lbs. My question is: what is the largest bolt size I will have to deal with on the RV10. Is there a recommended torque wrench size? If I want to cover off the requirements of Section 5, it looks like I will ultimately need at least two torque wrenches. Is this really the case?

The vast majority of the bolts are AN3 and AN4 size. There are some larger size bolts to hold on the engine mount, wings, wheels, etc. IIRC, the largest is AN7.

You'll need a big one (1/2") for the prop and a few things. You'll need a medium one (3/8") for a few duties like spark plugs and such.

I worked for some time on a Reno Air Sports racer this year. We have a highly modified Continental twin turbo, intercooled, ADI and water spray. We were trying to balance the EGTs. We purchased a set of drills, .001" apart in the range of the injectors. It took a few tries, but by examining the data from the engine monitor post flight, we reamed out the injectors on the hottest EGTs. After a while, we were running within 100 degrees or less across the board. (We were running very rich of peak, around 55 GPH at 42" boost, a lot of cooling by fuel. When we went over 44", the thing went to 65 gph, way too rich, very rough. The pilot could lean to run, but you don't have time to do that in a Race. Next year, the system will be changed so the Pilot only has to push the throttle.) We had a lot of spare injectors, but only went too far a couple of times. Seems .003 enlargement would get us around 180 degrees cooler. You have to drill with care and then sort of polish out the holes by spinning the shank of the drill in the hole for a time.

It looks as if the easy thing would be just to install a 10A breaker and upsize the wire to convert the boost pump circuit to a injection pump circuit but is that really what is best?

Problem: Attempt to remove a scratch in Plexiglas has created a visual ripple distortion at the repair site.

Scratch length 2-- hand wet sanded and sanded and sanded using 600-grit abrasive then 1000 grit slurry, 2000, and 3000. The repair area did polish nicely and no haze/fog can be seen. Just that blasted ripple where the scratch was located. Fix (?): Hopefully, there is someone out there that has been there and done that with regards to being too aggressive in removing a scratch. I would like to know if anyone has experienced a similar problem and how to fix it? My first thought, the repair area is too local and needs to be feathered it into the surrounding area.

I just got through priming my VS, Rudder, and the rear spar to the HS this weekend. I used the AFS gray primer/sealer and liked the results. My application wasn't perfect, but I honestly believe it was my technique ( or lack there of) that was the culprit. I chose AFS because it's water based so lower flammability issues (I'm working in my basement), lower fumes, and toxicity. I still wore a mask, but no one upstairs complained and I did have a window and door open with a fan running. I really can't rank it because I haven't used anything else, but it was easy to apply (Harbor Freight HVLP gun) and cleanup. I'm going to start smashing rivets tonight so I'll let you know how it holds up to that process. So I tentatively give it a thumbs up, but we'll see for sure after I abuse it a little. FYI, I also chose to go the Sanchem route vs. alodine, again trying to avoid toxic chemicals to maximum extent possible. This was also easy to use, but it didn't give me a warm fuzzy that the treatment is actually took. The color change was pretty uneven in places and on the whole, very light. I followed the directions to the letter so hopefully all is well, but there's know way to know for sure.

The kit comes with (or at least used to) a switching breaker (5A) for the boost pump. For Injected engines, you need a 10A. You can just switch out the breaker and change the size of wire, if necessary, based on the amperage and the length of the run. You don't ever, that I can think of, need the boost pump when the master is off, and you mainly just use it for startup when the master is on, of course. You definitely do not want to run it all the time when the ignition switch is in the RUN position. Just a breaker would certainly not be the way to go, even if it is a push/pull breaker. You want a switch, but again, that is what the kit comes with. It just happens to have the breaker in the switch as well (switching breaker) to keep things simple.

One of the things I posted a while back was a summary of a conversation I had with a instructor at a Sportair workshop. He is a long time A&P/IA, teaches A&P at a university in the DC area, EAA contributor, blah, blah, blah, knows his stuff and is a smart guy. Basically his thought on the matter was that with a single mag and a EI, the flame front would no longer meet at the optimum point because of the differences in timing. Now he didn't have any evidence that this would cause any problems, but his feeling was that it is less than optimum. This is why Klaus says that the addition of a second LSE wouldn't improve things very much, but it also shows that flame front propagation does have a measurable effect. This was one of the key factors that led me to make the decision on dual LSE's. There could also be a negative effect of additional stress if the flame front is no longer meeting in the center of the piston, but again I have no evidence of this and it was just a possibility the Sportair instructor mentioned. Wave propagation isn't the easiest thing to model but the guys at GAMI and some at Lycoming/Continental are doing a lot to understand it. This is the same reason you now see odd shaped piston heads in high performance applications, to get optimal wave propagation and focus the shockwaves in the cylinder.

Cox Sent: Friday, October 20, 2006 7:00 PM Subject: RE: RV10-List: Dual Lightspeed? Flame front propagation is a fascinating topic. F/A mixture is hotter near the exhaust valve that a comparatively cooler intake valve. Heat is a catalyst for combustion. If it is a charged carbon deposit and ignites a mixture at other than the required timing it gets its own name - Detonation. If the event happens before the piston is ready to provide the power-stroke and it is before the exalted event, it is called PRE - ignition. Read the GAMI site. The theory is they both meet in the middle in perfect harmony. Distributor, Mag timing and Electronic timing and all things spark related need to change with the change of engine load and rpm. A finite setting does not enhance this phenomena. The phrase Optimum is a mis-leader in that it is the better of a poor trade off. PRISM will address this need for a changing advanced spark curve. One of the vulnerabilities of Mags is they are Primeval - Brain Dead simple and reliable at a single setting throughout a range of performance requirements. Everyone building should make their personal decision based on research rather than popularity of the moment. John Cox ________________________________________________________________________________

Just to throw a skew on this, Allen HATES Lightspeed ignitions, especially dual. He sees better performance in the test stand off of mags and the install, and Klaus, can be a serious PITA compared to mags. Even with his strong objection (which he still mutters something under his breath when LSE comes up) I felt there is enough evidence out there to go with dual Lightspeeds. Mind you, that was my dual lightspeed IO-540-X on display at BPE's booth this last Airventure, but he wasn't happy about the LSE on it. Allen and his family were absolutely wonderful to work with and I bow to their much greater knowledge in engine building. But I had my mind set on the dual LSE's and they graciously accommodated that. The engine still turned out beautifully and is a work of art. Oh ya, and I have a standing offer for him to rip off the Lightspeed and put in good ole mags anytime. :-) If the eMag guys had their 6 cyl version ready I probably would have went with those. I was back in Texas this last weekend chatting with some of the guys in the know and the eMag guys have some really cool things they are working on and are moving to a new building to ramp up production.

>>. This is the same reason you now see odd shaped piston heads in high performance applications, to get optimal wave propagation and focus the shockwaves in the cylinder. I think I agree with all except the above, because mostly (at least in the automotive world) the piston dome shape is as a direct result of the size and shape of the combustion chamber in the cylinder head, and how much compression you want. You also end up having to have valve relief areas on the head of the piston depending on the lift of the camshaft profile so that the valves don't crash into the top of the piston. I think (just a hunch) the effect of wave propagation would be a very difficult thing to test by changing the shape of the top of the piston. Aftermarket cylinder heads for performance applications can have differently shaped combustion chambers (heart shaped, etc) and designs that have the valves sitting at a different angle, but this is an attempt to increase and optimize airflow. The sparkplug location is the thing I've heard of most being used as a tool in the hunt for a more optimal charge ignition. I suspect that optimizing the combustion chamber (including the top of the piston) for the speed at which the charge burns would be a tail chasing adventure, because you'd never get exactly the same conditions for each test. Too many variables. Mixture, slight changes in actual octane ratings of fuel, timing, cylinder leakage, charge contamination (water, oil). I guess you could build a sealed combustion chamber of a specific shape, compress gas in it, and ignite it, but you wouldn't be taking account of the movement of the air through the cylinder. Also, you'd basically be building a bomb :-). These are all things that I just think based on experience. I don't actually know anything.

I do believe that was the impression he gave me after my setup. :-) Didn't help that Klaus sent a used connector that was worthless and then tried to say it wasn't his problem. I've always had the impression from others that when the LSE worked, it was great but when it didn't, Klaus could be a pain to get a solution out of. Goes back to the whole starter, he said/she said thing with why Sky-tec's starters were being ripped apart on LSE installs. Klaus still insists it wasn't his fault and yet he modified his system to reduce the chances of kickback. I also went with the new Sky-tec Inline HT model rather than the stock PM model. Little pricier, and heavier, but more compact, lower inrush, and it has more torque. I don't see that as a problem for people that really want to run LSE. BPE does the basic mods necessary for LSE, and then runs it in the test cell with mags for benchmarking, leaving it to the home builder to do the LSE install.

The Feds are still in the stone age when alternators/generators lived extremely short lives and batteries tended to discharge fairly quickly due to the high draw from old-style electronics.

John, Good Luck in finding out the answer to this. I really hope that you (or someone does). I asked both Allen Barrett and Klaus S. directly. >From Allen I got: " I really don't know why it is this way perhaps it has something to do with Altitude, The engines on the dyno might perform better @ altitude with the EI than they do here on the ground, but I have no way of simulating altitude differences here in the dyno room". From Klaus S. " That's just what I'd expect an engine builder to say, they just don't want to be bothered with the extra work to hook up the LS EI to the dyno. (according to Allen there is several hours extra work involved). If it were true why would all of the Reno racers be running my ignition?" So, that's the extent of what I was able to get from 2 of the experts. Perhaps someone with more engine knowledge/wisdom than I who knows the more appropriate questions to ask could help to narrow down the mystery.

The carburated fuel pump is a Facet Pump and the injected engine uses an ES Airflow fuel pump. Thats the difference, but I do not know if there is any difference in power requirements. The electrical design per Van's wiring diagram calls for a 5 amp toggle switch breaker with 18 AWG wire. And no note for a difference between the 2 pumps.

My apologies to the world wide group but Fred's post below is just too good not to share in the spirit of improved knowledge. Can anyone here agree to the value of data like Tim and Michael present? Or is it just a bunch of Lurkers from OSH? I am going to Google "Speed with Economy". If it is available from Technical Books, then all the better.

John Cox #40600 ________________________________ From: Lancair Mailing List [mailto:lml(at)lancaironline.net] On Behalf Of Fred Moreno Sent: Monday, October 23, 2006 1:38 PM Subject: [LML] Hope, Denial, Money and Bullshit This forum is superb for exchanging ideas, problems, and solutions, but we seem to be very short on hard data. Maybe that is because it is hard to get, or because some people don't know how to calibrate and test carefully, or some don't want to know. As a result we have a lot of anecdotal evidence, much of which is clearly wrong. Example: one LIV-P owner proudly announced at the Lancair dinner he was getting 305 knots at 70%. I had flown in that the airplane, and knew the airspeed indicator was not calibrated, and the owner's calculation was based on an E6B which meant it had a built in 20 knot error based on OAT and compressibility effects. Put that in, and you get about 285 knots pretty much like everyone else. And he really had no clue about the exact power setting, just a guess. Maybe we just prefer rumors and BS to facts. Perhaps that is why rumors are so popular. Facts are such nasty things. They just won't go away. I propose we make a concerted effort to gather and exchange reproducible, defensible data, and share it with the group. Not the swing of the needle in an updraft or satisfying GPS reading while screaming downwind, but data that is good enough for us to compare the relative performance of props, modifications, etc. With the new Chelton (and other) instrumentation, factory calibrated far better than your steam gauges, good GPS data, and careful data recording (OAT, Altitude, fuel flow, etc.) we can get excellent data without a long and painful calibration process. The new Electronics International MVP-50 is also a superb instrument, built to good standards with reasonably accurate sensors and ability to record and regurgitate vast amounts of data. When I was ordering mine, I found that some of their customers have used the extra channels to monitor things like engine cooling air delta P, firewall temperature (how hot is that epoxy REALLY getting?), and other nuggets of information useful to the rest of us. This rant is motivated by last night's rereading Kent Paser's excellent book, Speed with Economy (1994, possibly available through EAA). It documents Kent's 20+ years of modifications with his 160 HP Mustang II. Kent is an aeronautical engineer, and took the time to calibrate his instruments and conduct careful experiments making changes one at a time to isolate what worked and what didn't. Net result: an increase of 64 MPH in top speed and 59 MPH in cruise speed. Slowed to his old economy cruise speed, fuel flow was cut IN HALF. Our Lancairs already incorporate a lot of the features that Kent explored and adopted, but most of us have failed to learn his (and other) lessons about exhaust systems, engine air cooling, exhaust air leakage in low pressure areas, where we should lavish our attention to detail and such. If we can collect and disseminate GOOD data in a format that another can study, digest, and learn, then we can advance our aviation interests even better than we are now doing. Moreno's challenge: produce and publish (here, of course) "test reports" documenting what you measured, how you measured it, if and how you checked your instruments, and any helpful comments. I promise that if I ever get my Lancair IV finished (early next year?) I will keep testing and recording and share the news, good or bad, because it should not be an ego thing, but a sharing of information thing to help advance our "state-of-the-art." I recall one year that Brent Regan and I walked around Oshkosh trying to capture the essence of the place in a few short words. The Greeks thought the world consisted of Earth, Air, Fire, and Water. We concluded that Oshkosh consisted of Hope, Denial (of the laws of physics), Money, and Bullshit. It need not be that way. Advancement comes from knowledge, and knowledge comes (in part) from testing, experiments, and real data.

Maybe that is because it is hard to get, or because some people don't know how to calibrate and test carefully, or some don't want to know. As a result we have a lot of anecdotal evidence, much of which is clearly wrong. Example: one LIV-P owner proudly announced at the Lancair dinner he was getting 305 knots at 70%. I had flown in that the airplane, and knew the airspeed indicator was not calibrated, and the owner's calculation was based on an E6B which meant it had a built in 20 knot error based on OAT and compressibility effects. Put that in, and you get about 285 knots pretty much like everyone else. And he really had no clue about the exact power setting, just a guess. Maybe we just prefer rumors and BS to facts. Perhaps that is why rumors are so popular. Facts are such nasty things. They just won't go away. I propose we make a concerted effort to gather and exchange reproducible, defensible data, and share it with the group. Not the swing of the needle in an updraft or satisfying GPS reading while screaming downwind, but data that is good enough for us to compare the relative performance of props, modifications, etc. With the new Chelton (and other) instrumentation, factory calibrated far better than your steam gauges, good GPS data, and careful data recording (OAT, Altitude, fuel flow, etc.) we can get excellent data without a long and painful calibration process. The new Electronics International MVP-50 is also a superb instrument, built to good standards with reasonably accurate sensors and ability to record and regurgitate vast amounts of data. When I was ordering mine, I found that some of their customers have used the extra channels to monitor things like engine cooling air delta P, firewall temperature (how hot is that epoxy REALLY getting?), and other nuggets of information useful to the rest of us. This rant is motivated by last night's rereading Kent Paser's excellent book, Speed with Economy (1994, possibly available through EAA). It documents Kent's 20+ years of modifications with his 160 HP Mustang II. Kent is an aeronautical engineer, and took the time to calibrate his instruments and conduct careful experiments making changes one at a time to isolate what worked and what didn't. Net result: an increase of 64 MPH in top speed and 59 MPH in cruise speed. Slowed to his old economy cruise speed, fuel flow was cut IN HALF. Our Lancairs already incorporate a lot of the features that Kent explored and adopted, but most of us have failed to learn his (and other) lessons about exhaust systems, engine air cooling, exhaust air leakage in low pressure areas, where we should lavish our attention to detail and such. If we can collect and disseminate GOOD data in a format that another can study, digest, and learn, then we can advance our aviation interests even better than we are now doing. Moreno's challenge: produce and publish (here, of course) "test reports" documenting what you measured, how you measured it, if and how you checked your instruments, and any helpful comments.

Subject: Re: Accidents in RVs
I don't think stall speed per se has that much to do with benign handling and accident characteristics, although it does correlate with what seems to matter. what seems important to me is the effort that it takes for the pilot to get an airplane stall, how much warning the plane gives, and how it behaves in a stall. for the really adventurous, getting an airplane into a spin and spin recovery can be added to this. like the RV-9, the RV-10 is very, very benign. it takes a long time to slow the plane down into a power-off stall, it is absolutely impossible to overlook getting close to stall, the plane can dawdle along at stall speed just fine, and stall recovery seems like less than 50' vertical loss. accelerated stalls are not that different in behavior. I don't have the chuzbe to try to spin the plane. (Chicken!). I learned to fly in a cherokee 160. I think the RV-9 and RV-10 are, if anything, more benign---and this is definitely an amazing feat. the reason is that in the cherokee, the panel is so high, it is not that obvious that your nose is pointing to the sky. with the better visibility in the RV, it becomes all the more obvious that your nose is pointing straight up now which is required to stall the plane. actual behavior of the airplane while approaching a stall and during a stall feels similar. Other things are of course easier in a cherokee. the cherokee is a flying truck. it will keep and hit its low airspeed and altitude better, but only because it is less "air-slippery." that is, in an RV-9 or RV-10, a thermal can make you gain 100' in altitude in no time. its almost sail-plane like. (this applied more to the RV-9 than the RV-10, but even the RV-10 is still more aerodynamic than the piper.) slowing down to the target speed is not as instant, either. this is not a safety issue, but if you want to fly by the numbers for IFR purposes, it requires more concentration and patience. and then there is the ground handling, which is not as easy for beginners---something RVs share with Cirrus and a lot of other airplanes (especially in cross-wind landings, where the castoring front wheel wants to not point straight). the piper's bigger wheels, shock absorbers, greater distance between wheels, and nose-wheel steering would be nice to have. I have never had a problem with it, but I am always a little unhappy with my cross-wind landings. It can't do it with the same smoothness I could do it with in the piper. personally, I think a well-built Vans RV-9 or RV-10 is the safest single-prop aircraft in the sky today. regards, /ivo http://welch.econ.brown.edu/n325hp/ ________________________________________________________________________________

So, Monty - If the amount of advance provided by the Lightspeed was less (and more in line with a NO CHANGE magneto) is there are potential for the benefits of electronic ignition without a commensurate drop in top end horsepower at cruise? Could there be room for improvement in the programmed timing curve of an electronic unit in your opinion?

Subject: Re: Fuselage Conduit Support
I put conduit under the baggage floor and supported it with adel clamps. However, I did not like the Van's conduit. It is too flexible, making it very difficult to route wire through. I bought 3/4" PEX pipe from the local plumbing store. It is more flexible than PVC, yet much more rigid than the corrugated black conduit. It is smooth on the inside and is just under 7/8" OD so it was easy to enlarge the holes with a 7/8" unibit. I also put the conduit down the full length of each wing, with a couple holes along the length to allow wires to exit. PEX pipe is made for plumbing, so I did a non-scientific test to compare it to Van's conduit. I used a heat gun to simulate an overheating wire. Try taking a heat gun to the corrugated conduit: it shrivels up like shrink wrap. By comparison the PEX is quite a bit more robust when it comes to heat. Photos attached.

Niko - to the best of my review, your question has still gone unanswered. The answer is, was and will remain - none. Now for the explanation. Best Practices in AC 43.13 is to leave wire runs supported at 6" intervals. The benefits are to reduce droop, reduce wire runs, reduce heat, enhance long term inspection. Tim posted on his RV-10 University site a DAR PowerPoint on aging aircraft wiring. It is blamed for the non-conspiracy cause of bringing down TWA flight 800 off the East Coast. Why is it used? Ease of wire pulling. Ease of retro modification. Why is the answer none. Cause it has been found to mask the tell tale signs of an incorrect wire size and the carry amperage of the material selected. Wire needs to keep cool. With heat, resistance goes up. Do airlines use conduit, yes in limited locations and usually light wall aluminum and for the reason of protecting wiring from chafing, adjacent heat sources such as exhaust stacks or de-ice lines. Conduit, unless transparent, masks the ability to inspect progressively. Do all certified GA aircraft avoid conduit, can't answer that. As little as practical I would guess. It is often 3-4x ID of the conduit over the OD on the final assembled wire bundle in it. Again for heat dissipation. Aluminum is great for radiating that heat build up away from selected hot spots. Yes there are things that cause hotspots in wire runs. In Experimental construction, we too often use automotive, lower grade components, switches and fuses, conduit and non-aviation grade products. The reasons given are often cost and convenience. Nothing is wrong with those, if the evaluation takes in all the appropriate informational input. You get to answer what is appropriate. So you can answer your own question. Ask yourself why specs are different between DC and AC rated switches. Can you functionally use the wiring tables to select the correct gage of wire for the wire run and current carry? Do you know the effects of heat on the adjacent bundle? Conduit is usually multiple run. Do you know the difference in momentary and continuous use wiring? I will bet that not one single builder will change their decision to use it. That is what makes building Experimentals so much fun. Convenience! Want to post this question on the aero-electric list and watch the verbal joust begin? Ask Stein, his opinion. Dan Checkoway did a pretty good post on his site for the failure of support tabs and the need to go in after one year and re-attach his wire runs.

This is really an interesting thread. I had hoped to follow-up the article with one on transition training; not just a "gee you need it" but a look at what habits or characteristics the non-transitioned pilot have. I then hoped to compare those with the Cirrus program to further define the differences between the transitioning RV pilot and the transitioning -- or learning -- Cirrus pilot. Don't get me wrong. I'm not into the "Cirrus is better" or "RV is better" debate that sometimes pops up. I'm just into analyzing RVs in the context of other airplanes, and RV pilots in relation to other pilots in an informative way. Alas, I've been unable to connect the two leading providers of transition training on Planet RV for various reasons.

John Thanks for the post. I think of all the old military aircraft I've seen over the years with wires bundled and tied to structure. I had a rough-in electrical inspection on a building project today and the inspector commented that the electrician did the right thing separating the wires nailed down a wall line. He said that the circuit breaker must be de-rated and / or the wire size increased if the wires are excessively bundled (quoted some code stuff and lost me), also the maximum length of conduit that a shielded wire can pass through is 24".

Subject: Re: Fuselage Conduit Support
All valid points, John. I would like to point out that one of the challenges that I found as the RV-10 comes together is getting the wire runs 100% done before I riveted th ose floor panels down permanently and before skinning and installing the wings. Call it convenience if you will, but I ended up doing 90% of my wire runs through the conduit long after those areas were sealed up. I certainly didn 't make that decision lightly. I realize that I deviated from a perfect world to make things come together. Are you going to stay away from conduit altogether? How do you plan on inspecting the wires under the baggage floor area?

Three distinct stages just like skin burns. Tim has some good sho ts. I had forwarded him the same presentation in Living Color. It is all about identification of an impending issue before reality sets in during flight. Otherwise the discussion migrates to inflight backup systems / vacuum gages , fire annunciation, fire suppression and software to identify the safest and quick route to the ground with a safe departure from the aircraft. Always use the lightest gage, the shortest run, the highest quality to meet the task and to inspect for impending potential problems. Wiring by its nature functions in a hostile environment.

I think of all the old military aircraft I've seen over the years with wires bundled and tied to structure. I had a rough-in electrical inspection on a building project today and the inspector commented that the electrician did the right thing separating the wires nailed down a wall line. He said that the circuit breaker must be de-rated and / or the wire size increased if the wires are excessively bundled (quoted some code stuff and lost me), also the maximum length of conduit that a shielded wire can pass through is 24".

The answer is, was and will remain - none. Now for the explanation. Best Practices in AC 43.13 is to leave wire runs supported at 6" intervals. The benefits are to reduce droop, reduce wire runs, reduce heat, enhance long term inspection. Tim posted on his RV-10 University site a DAR PowerPoint on aging aircraft wiring.

check with the maker of your engine monitor. If you are , for example, buying the GRT EIS 6000 you will be getting a floscan.

Subject: Aileron and Flap Rigging
I have a question about how other people adjusted the flaps and ailerons. The directions are a little unclear. The following is what I did and the assumptions I made. Did any one do something different? For the flap adjustment: Per the plans I lifted the flap up until it contacted the aft spar of the wing; this is the full up (reflex) position of the flaps. I adjusted the pushrod accordingly. Incidentally, this adjustment coincided with the trailing edge of the flap flush with the underside of the fuselage. That seemed aerodynamically and aesthetically pleasing. I adjusted the neutral position of the ailerons to match the reflexed position of the flaps. I did this so I would not have more camber on the outer portions of the wing while the flaps were in the reflex position (as that might cause the outer portions of the wing to stall first, leading to less than optimum stall characteristics). Furthermore, if I want my flaps reflexed for better cruise performance, why not my ailerons as well. This made aerodynamic sense to me, but the plans did not offer any guidance. Finally, when installing the wingtips I found that the wingtip rib did not line up with my ailerons as they were adjusted (the trailing of the wingtip sat lower than the ailerons in the neutral position). I made it work but the wingtips don't look quite right. The plane flies great, but it seems like something isn't quite right.

If your installing the Airflow Performance boost pump P/N 3090050, you will require a switched 10 amp circuit. We recommend a 10 amp breaker with #16 gauge wire minimum to supply the pump. The pump will draw 5-6 amps @ 30 PSI and there's a little inrush current on start up thus the 10 amp breaker.

Well, I based my search criteria off of what I saw other discussing recently. I thought it was one of the Jims or Johns mentioning using the 231. Yeah, I should know better than to put faith in other, non-hallowed Vans employees! A quick call to Vans may clear this up as to which model the supplied bracket fits, but even that may end up being universal to the 201 series and the 231 model. I didn't even check the aviation versions once I saw the search go to the 231. Funny there are no prices for the 201s, and no info on the 231! More research necessary!

Subject: Re: AOPA rebate program bites the dust - "how to" until year
end ... There was some discussion of this on the AOPA message board ( http://forums.aopa.org/showthread.php?t=15344) People who emailed Phil Boyer expressing concerns about the changes received this form letter in response: ------------------------------------ I have received the email you sent relative to my recent letter explaining the change in the AOPA credit card "FBO Rebate Program" caused by the merger of our long time credit card partner, MBNA and the Bank of America. Sending you a personal letter in advance of the official announcement, required by banking regulations, was at my insistence. I wanted you to hear directly from me, rather the impersonal nature of a bank communication. My apology for not providing enough detail to satisfy your concerns. First and foremost, in a perfect world, there is absolutely no way AOPA wanted to change the 5% FBO Rebate, other than to continue to make it better. As AOPA's leader I was very instrumental in convincing the bank to implement the original program - and it started at 2%. We worked with MBNA to increase it first to 3%, then to the 5% of today. AOPA worked with the bank to make it easier to redeem the rebate, with a fax alternative, and eventually online. We didn't do all this to end the program. We did it to provide members with a unique aviation cash rebate program attached to the Association credit card. And, while the rebate program was used by only a minority of our AOPA credit card holders it certainly was important to those of us who found the financial offsets to our flying valuable. Yes, I personally kept the monthly hangar bill and my annual on the AOPA MasterCard and benefited by almost reaching the $250 maximum rebate each year. The fact remains, businesses are sold, fail or merge, and the MBNA / Bank of America merger was front-page news in the Wall Street Journal and other financial publications. This major transaction was beyond the scope of influence your Association might exert on two banking "giants". Let's also keep in mind that the real reason for having the AOPA credit card has always been to support General Aviation, and that has not changed. Your association depends heavily on the royalty we receive from the credit card program, and it is the largest single source of income for AOPA. In the midst of the merger, let me assure you that my staff and I worked hard with to maintain the level of support that helps us pay for the advocacy efforts that keep you flying and the services, like free weather, flight planning, and airport information, that you value as an active pilot. When I became AOPA's third president in 1990, the membership dues were $39 a year. Due in large part to the membership using our AOPA branded credit card, dues in 2006 are still the same $39 annual fee. As those of you in business well know, we have added hundreds of no-charge member products, created a world class website, and other services, and all this without raising dues. While I understand that you may have many credit cards in your wallet, I hope you'll keep in mind that only one-the AOPA WorldPoints Rewards credit card-will give back to general aviation while rewarding you for every purchase you make. While I know it doesn't match the value of the 5% Rebate with a $250 annual max, the greatest group of rebate users was not in your and my "max-out" league, but had an annual rebate of $93. Thanks for allowing me this extra explanation, and I hope you will please continue to show your support for AOPA and GA by continuing to use your current card. You can continue to earn your rebate through the end of the year, and your current card will automatically begin earning aviation double reward points as of January 1, 2007. ----------------------------------------- -Adam Pirkle On 10/26/06, GRANSCOTT(at)aol.com wrote: > > In a message dated 10/26/2006 2:04:42 PM Eastern Daylight Time, > deej(at)deej.net writes: > > http://www.aopa.org/info/wpbrick/ > > I read the fine print, it seems the cash rebate is in the less than 1% > range and if you're happy going from 5% to 0.5% then that's OK or if you > want others collecting a bonus on your credit that's OK also.

Hey all - Here's a silly question that I've been wondering - why doesn't anyone use a flush latch on the oil door like on a Cessna? also, anyone know where you can pick one up? I was just looking at the baggage door latch, then started thinking about the Cessna version, which got me thinking about the oil door... of course, i'm supposed to be working... cj #40410 fuse www.perfectlygoodairplane.net ________________________________________________________________________________

I'm busy trying to work around the WD-415 issue on my elevators - got some new ones ordered from RivetHead (just wish he would hurry up). Anyway, I've been looking at the English Wheel. I first saw it at Sun 'n fun in '05 and again in '06. I'm seriously thinking about taking a course or two to get the skills. I've noticed that TM Technologies (who was at Sun 'n fun) has courses in California. Also found a motorcycle style course nearby in Tennessee. My dream is to build my cowling and wheel pants out of good 'ole Al-u-min-ium. Motivation is the desire for very dark paint; plus the fact that I'm not a primer - I do ACF-50 and/or Boeshield T-9 ( I need to do penitence somewhere...). Any recommendations/comments/flames about wheeling out there? John -------- #40572 Empennage - starting Elevators!

> > Like this? > > http://www.justrvparts.com/Oil%20Door%20Hidden%20Hinge.htm This idea (the hidden hinge) can be taken one step further. By using piano hinge to secure the unhinged free edge of the door instead of cam locks and extending the wire forward to a retainer on the cowl interior upper surface there are no fasters or hinges of any kind visible on the outside of the airplane. Worked great for 10 years on an old 4. This uses the same principal as the hinge pins that join the upper and lower cowlings.

I am also awaiting some parts from Rivethead-Aero (H-stab attach brackets). When I enquired about the status of my order via email, Dave sent me a reply apologizing for the delay and telling me he fell and broke his hip on 10/20, and that has delayed the processing of some orders. He is getting some help together to package parts, and he hopes to be shipping orders again soon. -------- Empennage Read this topic online here: http://forums.matronics.com/viewtopic.php?p=70663#70663 ________________________________________________________________________________
