I'll offer an opinion (oh, geez another one of those smelly things). Being an owner of a certified four place airplane, I really believe the cruiser crowd is laying in wait for this 4 seater to come out. Up to this point the only options available were glass or fabric with either mega bucks involved or from a company that did not offer anything "go fast". Van's is a trusted company with a vast history to follow. Sure, there are always going to be people buying new A36s but in my case, I'm just thinking out loud here, I could probably pull the 225HP engine and C/S prop out of my older Bonanza (plus I have another 225HP core and jugs, 0 time yellow tagged crank, cam, case, rods, acc. case etc. sitting in the hangar), pull the radios, avionics and such and either part out or selll the airframe to a scrap house and come out way ahead of the game. I would not be at the mercy of my wishy washy IA/AP (this is not an indictment against any IA/AP on this list, just my local one) on a yearly basis. In this case, I'd have a "go fast" and I'd have a cruiser............best of both worlds. I'm thinking Van's will not be able to make them fast enough.

I have just completed the W&B of my new RV-4. It is 180 hp, Hartzell prop, vacuum pump, etc. No paint. EW is 1036. The EWCG is just forward of the forward limit (67.39). With me in it and full fuel, CG is 69.4 (.8 aft of the forward limit). The RV-4 I just sold was similarly equipped except it was painted. It's CG was about .8 inches aft of the new one. I have flow the RV-4 in all CG ranges and it is really not an issue provided you are aware of the change in pitch sensitivity at aft CG and also trim accordingly for takeoff. I could be curious to know if other 180 hp, CS prop, RV-4s also end up with their EWCGs forward of the forward limit. The thought occured to be to perhaps bolt some lead in the tail to bring it a little further aft.

I predict Van's will sell more RV-10s than any other kit they have ever made. Regarding it looking similar to other designs, there are fundamental design reasons why it will look similar to many other newer four places; why do you think jet airliners all look so similar?

Something about heating and expanding the air... > Scott in VAncouver The Mustang has a pitot type cooling intake. Then the air is expanded in the "doghouse" and passes through the radiator and finally is recompressed and accelerated by closing the cooling exit door. It recovers some of the heat in the coolant as thrust that way. It is an Amazing system. But some major drawbacks to the P-51 cooling system are: The coolant pipes run through the cockpit, if they rupture, you have boiled pilot on the menu. The Merlin will not run for more than a couple minutes without coolant, even at low power, so a cooling system failure most likely means you will go farming.... Chasing coolant leaks is a continuous chore on the Mustang. Heating and cooling the rubber hoses causes them to be crushed by the hose clamps and then they seep. If you leave the airplane in an unheated hanger, the hoses shrink and then you find a puddle under the airplane. I think this partly because every thing we clamp the hoses on is pretty light gauge aluminum and it has a higher coeffiecent of expansion than iron and you can't crank down on the clamps or you will crush the pipes. Don't get me wrong, the Mustang is a WONDERFUL airplane to fly, but Van Grunsven captured most of the good aspects of the airplane without out the bad manners. I also have a good friend who had a Liquid-cooled Cessna 414 and it went like a scalded cat! But it was a maintenance nightmare. Long-term, a liquid cooled aircraft engine would be a wonderful thing, but so far, none of them have been as trustworthy, or as trouble-free as a Lycosaurus. Cavalier tried to convert P-51s to corporate chariots and it didn't work, and their are plenty of reasons why.

I'm inclinded to agree. I run a web site for an RV builder's group, through which I have contact with many RV wannabes. For years, one of the most common comments has been, "Too bad they don't make a four-seater." There are a lot of potential builders out there who can justify building an RV if it has four seats, but not if it has only two.

Something about heating and expanding the air... > > Scott in VAncouver Scott: This is common practice in formula-type racing cars. They also vary the size of the outlet duct for different air temperatures and track speeds, which in the case of a racing car varies downforce (i.e. negative lift) as well as drag. Essentially, it's the same principle as a jet engine. The air comes in, expands to a higher pressure in the duct, is heated by the radiator, and then accelerated out through the exhaust duct to create thrust. In practice, though, I think the thrust you generate doesn't exceed the drag of having the radiator in the first place. If you add a bunch of ducted radiators I wouldn't expect to go faster! But if you can add water cooling without adversely affecting the profile drag much (think Mosquito) you should be able to have quite a bit less drag than a dypical air-cooled engine installation.

Not only does that make test flying simpler, but their initial performance numbers will be "buffed" a little because of reduced weight, drag, etc. And, please don't get me started on this "light IFR" cr*p. You either know how to fly in the soup with ice building up on your wings or you don't. End of story. Well, not really, 'cause then we have to make sure to mention partial panel work--EVEN IF YOU ONLY FLY *VFR*. If you fly enough, one of these days the weather gods are going to snag you and if you haven't practiced flying in the sh*t, you're gonna die--fairly simple logic. All you need is your T&B (TC), airspeed, altimeter and a stop watch--please don't depend on your VSI if your life depends on it!)-- (your VSI is always chasing the airplane, so it's never really sure where it is at any exact moment)--now, if we all took some hints from our glider/soaring friends and put Variometers in......

Combine that info with the fact that the datum, or zero point for moment calculations is 70" in front of the wing leading edge on the 8 and you can figure the datum for any installation location once you locate the leading edge on the drawing. As the drawing gives the location of the main spar, a measurement on my AC puts the leading edge 16 1/4" forward of the front of the main spar box which is at station 33 13/16. So, I convert station to datum by adding 70 + 16 1/4" - 33 13/16" or 52 7/16" to the station. Dave Reel - RV8A ________________________________ Message 13 ____________________________________ Time: 08:23:46 AM PST US From: Jim Oke Subject: Re: RV-List: RV-10, oh No, an opinion!! --> RV-List message posted by: Jim Oke I think we can be reasonably certain that the proprietor of Van's aircraft has done a most careful market assessment for the RV-10 project and is confident the demand is there for the right 4-seat design. Everyone has an opinion so IMHO, the RV-10 is directed at the Cessna/Piper four seater replacement/upgrade market and not what might be called the "traditional RV sport aviator" market which is in truth rather limited. I have no real stats at hand but would say the vast majority of GA airplanes in North America are utility four-seaters of the 172/Cherokee 140 class. These airplanes are getting old and cost lots to maintain and operate with new 172s up in the quarter million $$ range. When 172/Cherokee owners find out that they can acquire an RV-10 for perhaps 1/4 the cost of a new 172, go faster and farther with the same payload on any given day and for a fraction of the cost of ownership, that will create a really big market for the RV-10. Homebuilding is obviously not for everyone, but if Van's can persuade 2% of 172/Cherokee owners that building an RV-10 will provide them with better/cheaper transportation, that would be a very significant piece of business. The RV-10 roll out is probably targeted for Oshkosh in a few months. If Flying magazine does a positive pilot report and calls it a better, more useful airplane than (for instance) a 172 then watch out for demand to go through the roof. Hopefully Van's has a suitable contingency plan in place for this (and I would be surprised if they did not). The target RV-10 market is probably looking more towards acquiring a completed airplane than personally handcrafting the "ideal RV" so look for more quickbuild options such as prewired instrument panels and such to made available. Just my opinion, of course.

He was doing his market research then a little bit I think 'cause he turned the tables on us some and asked me and my buddy what we thought. I told him I'd want it to be 2 seat acro capable and he shot that down with an example of another similar plane that had trouble that was already out there which I can't think of at the moment. I told him that if I wanted a 4 seater that wasn't acro, I'd just as soon rent a high performance plane if I just had to get somewhere REALLY fast. More efficient use of my time than building another plane when I have a lot of other hobbies I like to spend $ and time on. He told us he wasn't sure the market was really there for a non-certified, slower than glass 4 seat touring mission plane and they had other projects that they had to finish up at the time. I think the sailplane and/or the RV-9 were those projects. He said he was very worried people would try to fly acro in them anyway and get 4 people killed. He also said he was worried more people would try to fly IFR in them and as a result get more RVs in fatal accident reports. I believe the RV-8 demo fatal accident had to be in the forefront of his mind at the time. At that time I thought he was being too conservative and that the idea would really take off. However, the economy is quite different than it was 2 or 3 aprils ago and that has the industry folks spooked which is why you saw so much press coverage about sun-n-fun attendance and saw those kids doing the economic surveys down there everyday this year. He probably now thinks he can get some of the currrent RV'rs who may no longer need the acro mission and have extra $ to jump in and prime the pipeline and he can attract some of the glassy customers if he can approach their performance at a reasonably lower cost after some initial good customer feedback. A sometimes overlooked point is that the pipers/cessnas are popular in part because they are certified and ideal for training and rental missions. To many folks with money for larger planes, that's a plus. We haven't seen the price for the kit yet. It could be more expensive than some are hoping. I hope not but they are advertising price yet, are they? Oh well, the karma wheel spins around and around. I just know that when I look at it, if I was going to buy something like that, I'd rather by a glassy plane and that was by far and away the sentiment of most of the folks at work I showed the pictures to too. It would be nice if some folks did start buying 540s instead of 360s, that's for sure!

I won't bore you with the details but the bottom line is that in order to get the required number of BTUs to the skin, the coolant distribution system is prohibitively heavy. It could be succesful *IF* the wing structure were designed from the start with this in mind. A retrofit is, in all likelyhood, impractical. Now for the possible. I did an experiment to determine if the return fuel from my EFI system could be used to cool my oil. (the rotary engine rejects 33% of cooling BTUs into the oil). The wet wing tanks of the RV would then disipate the heat picked up by the fuel. The experiment was a "failure" because the return fuel rate was too low (~15 GPH) and it only reduced oil temp by 2 deg. F. *But* , temp rise in the single wing tank used was below measurement threshold (.2 deg F) I plan to repeat the test using a dedicated high volume pump and utilizing both tanks on my RV-8. Cooling drag is said to represent 30% of total aircraft drag on a reasonably clean aircraft. If 1/3 of this can be eliminated it would be a success. Airframe designers would sell their mothers for a 10% drag reduction.

The idea is to get the heat out of the engine and into the air. Why interpose water as there is still the problem of getting the heat into the air. Air cooling has a number of advantages. Water cooling has a number of disadvantages. If you begin with a water cooled engine then you are stuck with having to interpose water but not otherwise. What we really need is a better air cooled engine. One that doesn't vibrate, doesn't suffer shock cooling, regulates its own temperature, isn't so expensive (has competition) and consumes less fuel.

Two S-N-Fs ago I spoke at length with Ken Green about the four-place plane they were considering. The thrust of the conversation was about the market niche that may or may not exist for the RV-10. My contention was that it would be sold primarily to individuals that do not represent the current builders of the two-place designs. The current RVs are wildly popular because they hit a financial "sweet spot" that many, many builders can accommodate. While there are builders of current models that have the financial resources to spend whatever money they wish on a project, I suggest that most RVs have been built by folks that are at their financial limit (or beyond!) for a hobby project. The range of $40K-$60K for a project is attainable for a large number of builders who can not spend $100K+ for a more sophisticated design. But.........$40K-$60K will not come close to building an RV-10. And this was the point of my discussion with Ken. This means the RV-10 will fall into a vastly different market niche than the current models. Ken readily agreed with my assessment and stated that there was concern within management that they might be designing a plane that might be difficult to sell in quantities that would be profitable. But, he said that the company is now financially secure enough that they can "roll the dice" and see what the market can bear. If the RV-10 is as successful as some of the listers have predicted, then the competition will have another 800 lb gorilla to deal with! If not, then it was Ken's opinion that Vans could carry the expense of the four-place experiment without unduly impacting the bottom line. The reasons I predict the RV-10 will be built in relatively small quantities are thus: 1) The completed cost will be far above what most current RV builders are experiencing, because.... 2) Most RV-10 builders will not be able to justify such a plane with VFR-only capabilities. This means that serious panels are going to be installed, which means that..... 3) The engine/prop expenses will be considerably higher since who will want to put a half-worn-out motor in a nice four-place plane with a nice panel, which means..... 4) Insurance cost will be considerably higher since the hull value will escalate, and four souls are now at risk. 5) The biggest chunk of potential buyers will be those who have absolutely no interest in building a plane. Will they overcome their aversion to building in sufficient quantities to abandon their Mooneys, Cherokees, and Cessnas, and create a substantial fleet of RV-10s? All this means that Vans is striking out into a market far, far different than the one they have dominated for fifteen years. There is no doubt the RV-10 will be a nice kit, but $100,000 dollars will buy some decent certificated four place planes. All the points I have raised have been thoroughly examined by the management of Vans, and due to the maturity of the company, they are willing to have a go to see what happens. But ask the guys at Vans if they predict a runaway best seller, and I suspect you will receive a subdued answer at this point in time. I wish the very best for the RV-10 endeavor and expect it to be well received by the builders who decide this project fits their needs and budgets.

Water cooling can deliver a constant temp bath for the engine under a certain set of conditions--which improves the recently discussed BSFC, as if we didn't have airplanes to build, which I don't because my airplane was built in 1998--so, some of us gotta talk about flying, or making crappy jokes or just sorta shootin' bull. kempthornes wrote: >--> RV-List message posted by: kempthornes > >At 05:36 PM 5/16/2003 -0600, you wrote: > > >>--> RV-List message posted by: Bill Dube >> >> I know that there are very few water-cooled aircraft, >> >> > >Why use water cooling?

I have just completed the W&B of my new RV-4. It is 180 hp, Hartzell prop, vacuum pump, etc. No paint. EW is 1036. The EWCG is just forward of the forward limit (67.39).

I have flow the RV-4 in all CG ranges and it is really not an issue provided you are aware of the change in pitch sensitivity at aft CG and also trim accordingly for takeoff. I could be curious to know if other 180 hp, CS prop, RV-4s also end up with their EWCGs forward of the forward limit.

Sam brings up some very valid points however I'd like to offer this point of view. I believe the people who are interested in the 10 know about the 10 and are willing to take on the process. I don't think there are that many out there that wake up one day and say, "I think I'll build a plane and I think it will be an RV10." I think this occurred with the others in the series but the 10 is definitely a niche market. Yes it will cost more. It is going to include the seats for liability and safety concerns which mean more. It is just plain bigger too. I would say though that because it can be "paid for" in phases it will be a very desirable airframe. That is why I'm building an Aerocomp 7SL cause I can have Cherokee 6 carrying capability at less than 125K, it will be new and I will have built it. I'd have to say I think it will be popular but not to the point of long waits and stop everything else numbers. Now I'm hoping that a bunch of 7 builders will abandon their projects in favor of the 10 and I can pick up a pocket rocket to go along with my hauler!!!! Also keep in mind that in the case of the 10 we are seeing PROTOTYPE is both an noun and a verb. Darwin N.

Hal: As I'm sure you're aware, there are many cases where heat is transferred by a two (or more) stage process. These things don't happen because people are too dumb to know better, they happen because there are distinct engineering advantages. In the case of liquid cooled engines, the advantages are many. Someone already mentioned the more consistent cylinder temperature you get with liquid cooling. That alone leads to quite a few advantages. Less, and less troublesome, hot spots in the combustion chamber mean that the engine is more resistant to pre-ignition. That means you can use a higher compression ratio. Notice how much higher the compression ratios are on liquid cooled engines that don't have to meet emission regulations. Auto racing engines run anywhere from 9:1 to 12:1 on avgas. A higher compression ratio leads directly to lower specific fuel consumption. Reduced hot spots also lead to lower nitrous oxide emissions. That's not a problem for airplane engines yet, but I think we can count the days until it is. Air cooled auto engines died when emission regulations got stricter. The few that remained got liquid-cooled cylinder heads. Water cooled engines are structurally stiffer, which not only makes them mechanically quieter but also allows higher RPMs, enabling you to recoup some or all of the lost power-to-weight ratio. That's why nearly all new motorcycle engines are liquid cooled. Notice how even with liquid cooling and a gear reduction drive the Eggenfellner Subaru is still a close match for a Lycoming in power-to-weight ratio. Liquid cooling also provides better cooling (and hence better lubrication) for the valve stems. Stuck valves, a persistent problem on Lycomings, is virtually uknown in liquid cooled engines. Yet another benefit of liquid cooling is that the more consistent temperatures allow tighter-fitting pistons and rings, which leads to longer engine life. Check the room-temperature clearance limits for a Lycoming piston as compared to, say, the Subaru. You're going to get a lot more life out of the piston rings in a liquid cooled engine (if other engine operating conditions are similar). Once you move away from direct drive (i.e. RPM limited by prop speed), liquid cooling makes more sense than air cooling, even in an airplane--especially the cylinder heads.

But I want to reiterate the point that there are a LOT of potential builders out there who want four seats. Whether they can afford the RV-10 or not I can't say. I also agree with Sam that RV-10 builders will mostly be people who wouldn't build a two-seat RV (or perhaps some will be "repeat offenders"). That's a point in favour of the -10 from Van's perspective, since it means they won't be cannibalizing sales of other models.

That is two to six existing RV builders forming a flying club and building an RV-10 for use by the club members. They still keep their RV-4/6/7/8 for the majority of their flying and for the times they want a four place plane they have access to the club plane that they each put $25,000 into. Six experienced builders should be able to put a pre punched RV-10 together in less than a year. $100,000 invested and probably a resale value of $200,000 - not too bad. Heck, sell the first one to pay for the second one. They would still have the second one done in less than two years. Would also think that experienced RV builders will soon be in demand.

There are RV builders everywhere. Even if you have to base the plane at a distant airport, because everyone in the group doesn't live real close.

It turned out real nice. I arrived Saturday morning around 9:30 AM which seemed to be near the peak arrival time. I know it impressed the Austin approach controllers. When they were letting people change frequency they were saying things like "I swear there are 15 people on final now. Be careful!" While I was flying the arrival procedure the tower kind of threw in the towel. He said something like, "there are too many of you. Sort it out." From this point there was a much calmer radio frequency. The tower just stepped in where they though they could help. Things like "don't slow down on the runway. Keep the speed up." No landing clearances or anything like that. When I was on final, there were about 10 or 12 of us S turning, trying to keep spacing. Seemed to work pretty well but it did put me in mind of how easy it would be to have a bad accident where you are in a pressure situation, at minimum speed and S turning near the ground with your attention on the plane in front of you. I was parked between an original design, reminiscent of a 30's racer, and a rotary powered RV-6A. My friend Judy Stocks was just one down. Remarkable, since we did not coordinate and came from far different places, just like Brian Denk at Waco and Las Cruces. The parking areas were adequate, but rough. You did not want to see a nosedragger RV taxi by. There were some remarkable nose gear gyrations. Some of the canard type guys could not really handle it. Every fly-in is an RV fly-in now. Face it. We are as common as dirt. I have no idea how many there were. One guy was inventorying but had not finished when I talked to him. He had done about 50 at that time. There was one of those fancy-smancy ones, an RV-6A, out of Florida. You know; with the polished firewall, carbon fiber plenum, color coordinated engine accessories and full panel. It was real nice, but as I told him, my airplane is over 100 pounds lighter. You have to cling to something for your own self respect. I also critisized him, to his face, for being obsessive compulsive. There were a lot of RV formation fly-bys, with 16 RV's and some Bonanzas. Did not even dent the number of RV's on the field. I saw Larry Vetterman's Rocket, from South Dakota, but missed him. There were many nice Rockets. There was also Bruce Bohannan's hopped up RV-4. I got I kick out of talking to him. It now has a huge scoop on the top of the cowl and a huge intercooler behind that. This is for cooling and also for windshield defrosting, as the air exit is just ahead of the windshield. He mentioned that this heavy RV-4 flies a lot nicer at 40,000 feet than down low, where the ailerons are a little heavy. He indicated that the engine power produced is predicated on cooling. For instance he tries to keep the cylinder heads below 500 degrees F. He also has to do a lot of balancing to prevent turbocharger blade stall. When I asked him what the level flight indicated airspeed is at 40,000 he told me, and said that calculated out to about 333 mph. Tracy Saylor and Dave Anders have some fast RV's, but I guess Bruce's is about as fast as they get. The 50,000 foot flight waits on a pressure suit. Bruce said that they were having trouble getting one from the government. If anyone knows someone or has something, contact Bruce. We need this RV at 50,000 feet. I asked about wing extensions for the higher altitude, and he said they had them, but he did not think they would be necessary. What a remarkable airplane. Bruce said he thanks Van every time he sees him, but Van says, well, it is just a standard airfoil. The turn-out was huge. I don't know the numbers, but the marshall who escorted me out, said there were more airplanes here than at Sun and Fun. The number of planes he mentioned didn't seem possible to me, but if he is right, I guess that would make this the new second largest fly-in. There were certainly way too many very interesting airplanes to near look at in the one day I spent. A Dyke Delta, the Polen Special and many one of a kinds were there. There were warbirds, and turboprop 4 seaters, including a certified turboprop, pressurized version of the Myers, that they hope to put in production. Jim Bede was there with some BD-17's. Jim Bede! If you need any better proof of the good manners of flying people, I don't know what it would be. Jim is up there being interviewed as some kind of aeronautical hero while all the people he owes money to, including me, don't even try to ascend the podium to lynch him. Van's had an RV-7A. I sat down in the cafe for lunch without much delay or trouble. There was also a food court with buffet and another area with sandwich type places. The weather was warm, dry and pleasant. Just to the point where you needed to be sure and have a drink fairly often. The organizers did many things right. The airport was never closed, which is a big deal to me. I hate to have to wait till too late to leave, because someone is having a good time in an aerobatic plane. Gas was just $2.12. There were plenty of volunteers to guide you every step of the way while taxiing. There were shade awnings spaced ever so often, which turned out to be just great to sit down in the shade and rest once in a while. There was transportation along the flight line, for those who like that sort of thing. A very enjoyable day, and the trip over and back showed once again what a remarkable plane an RV is. A friend of mine flew over from the same airport I did, in New Mexico. He flew a cherokee 180 and burned over 30 gallons while I burned 14.7 with the same engine, in much less time. With the ability to go high or low, you can outsmart the winds to a large extent. Going over I went at 11,500 at around 190 knots most of the time, burning about 7 gph. Coming back, I went lower, with ground speeds starting at about 150 knots and increasing to 165 knots near home at a burn of about 8 gph. What Fun!

I'll offer an opinion (oh, geez another one of those smelly things). Being an owner of a certified four place airplane, I really believe the cruiser crowd is laying in wait for this 4 seater to come out. Up to this point the only options available were glass or fabric with either mega bucks involved or from a company that did not offer anything "go fast". Van's is a trusted company with a vast history to follow. Sure, there are always going to be people buying new A36s but in my case, I'm just thinking out loud here, I could probably pull the 225HP engine and C/S prop out of my older Bonanza (plus I have another 225HP core and jugs, 0 time yellow tagged crank, cam, case, rods, acc. case etc. sitting in the hangar), pull the radios, avionics and such and either part out or selll the airframe to a scrap house and come out way ahead of the game. I would not be at the mercy of my wishy washy IA/AP (this is not an indictment against any IA/AP on this list, just my local one) on a yearly basis. In this case, I'd have a "go fast" and I'd have a cruiser............best of both worlds. I'm thinking Van's will not be able to make them fast enough.

How different? Well, I have seen lots of mention of shiny new C/S O-360s and IFR capable GPSs going into RV-6s, 7s, and 8s, which means the cost of Van's kits is down around 25% of the finished cost of say $60-70k at minimum. That's fine and everyone is certainly welcome to build at this level if that the flavour they choose but the point is a "basic" RV-10 will probably not be much different in cost than some of the more "delux" RV6/7/8s. A recent Flying magazine had a feature on used Cessna 182s - the writer seemed to feel a 25 year old Skylane with a half life engine and average avionics was an excellent buy at $90-$100 k. Stir in $50k worth of new avionics and you would have a pretty good airplane was the spin. I would suggest the cost comparision to make is thus not a $75k RV-10 versus a $40k RV-6 but against a $100k used Skylane. If it can be shown that an RV-10 will provide similar utility as a Skylane then the choice becomes attractive one even figuring the 3-5 years construction time in. (New Skylanes are available at $250,000 for those so interested, of course.) Ongoing costs of ownership should also favour an RV-10.

So so I can't apply that formula because we're not talking about a finite count of gas molecules because we have continuous flow of them. I'll agree to a presurre rise when a flow is slowed down. However, if it's slowed down into an expanding area I don't believe the pressure rises as much as it would if it was slowed down into a non-expanded area. In a jet engine it is the compressor that increases the pressure? Finn Tedd McHenry wrote: >--> RV-List message posted by: Tedd McHenry > > > >>>Essentially, it's the same principle as a jet engine.

I found an RV-6A project with two empennages (90% complete), wing (80% complete), and fuselage (not started) this weekend. I blame it all on Jeff Crab and Sam Buchanan (TVRVBG) for giving me rides in their sixes :) Hopefully in the next 2-3 years I can start making their weekly breakfast in my RV :) I've started the inventory to find out where to get started. It appears I need to finish the control surfaces for the empennage and finish the tanks and skins for the wings. I'll try to get some pictures tomorrow. Ironically I picked up the parts in a 6x12 UHaul trailer. The numbers RV 2295 G were on the trailer. Could this be some type of omen? :) I'm chomping at the bit to get going. I know it's a long road ahead but I think I'm up to the challenge. I just hope I haven't gotten too spoiled to the predrilled -7 parts. -David Taylor (N207DT reserved) empennage/wings Warner Robins, GA ________________________________ Message 65 ____________________________________ Time: 10:14:03 PM PST US From: "John Starn" Subject: Re: RV-List: Wing cooling (another wacky idea); pressure recovery & flyin notice --> RV-List message posted by: "John Starn" Are you saying that the rate of flow at the edges is exactly the same as in the center of the river and the fact that there is more volume at this time of year is not the cause of the increase pressure in the center of said wider river.
