Like you I am interested to learn and it seems the older I get the stronger the interest grows. You need not be concerned about this thread ending any time soon. It lives too close to the needs of the average Builder, would be or want to be homebuilder. It's a fact that powering the aircraft designs that call for Lycoming engines often represents half or more of the project cost. I think this alone sends too many off in search alternative projects never mind alternative engines. I for one would like that to change. If I was wealthier and younger I would be up all night shoe-horning some alternative engine or another into One of Van's creations. Most likely the driving force would be the nay Sayers. If the current thread fades away for a while, cruise through the archives the last go around on this topic was quite entertaining!

Moving into this part of the project now, I am looking at 3/8 fitting on fuel lines and smaller fittings required for the in line filter, fuel valve and gascolator. Do I have the wrong size valve or are builders closing down the diameter of the fuel lines to go through the filters and valve and then back out to the full 3/8 size fitting through the aux fuel pump, back down for the gascolator and then back to 3/8 into the engine driven pump? I have an 0-360 and am curious about fuel flow on max power such as takeoff. Any experiences, or recomendations would be appreciated. Do not archive.

Perhaps the list could have moderators, long time members who would have the power to "edit" offensive or inflammatory material. Sometimes people say things that are meant as harmless and it does not come across that way. For a well run forum visit www.tractorbynet . It is the most civil, friendly place on the net.

I have been tempted to jump in when some people start flaming or get off on a political tangent, but I have never done so. I found out , early on, that nearly every one of us is normal and even after a bad day or brain fart we will quickly return to normal. I guess there are pros and cons to a moderated list. This particular list has done very well without moderation because the list host (Matt Dralle) has done his job well. He also has "the button", but has probably never had to use it. After many years of watching/listening moderated political debates, I long to see two candidated on their own. The ensuing screaming and arguing would probably give us a truer picture of the candidates position and abilities. Similarly on this list, I get a good feel for what The RV builders think of a particular subject and I get it fast. The really cool thing about this list is that people who are smart enough to build an airplane are smart enough to select what works best for them ( I do not include myself since I bought my RV-4) When a question is asked and ten responses come back, we can easily pick out the right from the wrong, and which of the "right" is most appropriate for us. In the back of my mind, I know that Matt and the rest of us can control the chaos and sift thru the posts to get the good stuff out. And there is a lot of good stuff.

The pilot on my redrive is only .25" long and this may not be enough if the seal is at the pilot.

(BSFC about .6 lb/hp/hr) At best power mixture, the IO - 360 Lyc burns the same as my 13B rotary, about 20 GPH at full tilt. At best economy mixture it's down to about 15 GPH, but power is down a bit. Note that this figure has no resembalance to typical cruise fuel burn. Tracy Crook ________________________________ Message 11 ____________________________________ Time: 08:53:44 AM PST US From: "Tracy Crook" Subject: Re: RV-List: Wheel pant openings --> RV-List message posted by: "Tracy Crook" Bernie Kerr had an interesting take on this subject that I thought made good sense. The smaller the gap, the lower the drag so his thought was to raise the level of the pant opening so that the lower edge of the pant was above the point where the tire bulges around the contact patch. This requires the smallest gap and would more than make up for the increased exposure of the tire. Also results in less 'pant rash' on rough fields or crossing bumps.

Band looks like minus sign, opposing signs oppose flow, therefore band goes to positive. (when used for blocking) Please don't nit pic as to whether or not opposing signs oppose flow.

One of sources of confusion during this discussion has been that the civilian world uses a "positive current flow" model (a.k.a. "hole" flow), and the military world uses negative current flow ("electron" flow). I will refrain from comments about the military mind. The way I keep it straight is to look at the schematic symbol for a diode...a arrowhead with a band across the pointed end. A forward biased diode will flow postive current in the direction of the arrow with a 0.6 V drop across it. It will block current up to its max voltage rating in the other direction. The band on the diode package corresponds to the band on the symbol. So, for a spike catching application, the band on the package should be toward the positive voltage, and the other end toward ground. John Huft RV8 Pagosa Springs, CO p.s. Larry, 2 cents is too much for your advise. Voltage does not flow, it is a force. neutrons are chargeless (neutral), so they do not enter into the picture. sorry, no insult intended -----Original Message----- From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com]On Behalf Of lm4@juno.com Subject: Re: RV-List: Protection diodes on starter solenoid --> RV-List message posted by: lm4@juno.com Well, That does it.

Both have 3/8" fittings. I do not have an in-line filter for two reasons: First, the gascolator has a very fine mesh filter element cylinder that can be unscrewed from the body and has 3 (or 4, I forget which) mesh sections round the cylinder. Second, I followed, what I think was a brilliant idea of Eustace Bowhay and Jim Rowe to mount the gascolator in the space between the wing root and fuselage side. (As published in the August 96 RVator).Nice and cool there and at a lower point than available on the firewall. Also, my installation is BEFORE the Facet fuel-pump, thus preventing tank crud getting into it. I have easy access to it through a hinged trap-door section in the bottom portion of the WRF. This was done on my 6-A. The RVator article says it should work on the 8's but doubt there is enough space to mount it there on the 4's. The "proof-of-the-pudding" fuel-flow test, with the A/C set at 17.5 degree climb angle and 2 1/2 USG in each tank, that little Facet pump supplied fuel at a rate of 36 USG per hour as measured right at the carb fitting! (Both tanks).

OK, here is the way to tell how to install the diode: put two diodes on the solenoid in parallel, one of them one way and the other the other way. Connect to battery, energize solenoid and look for the one that smokes. The other one is installed the correct way. Next thing we know, someone will talk about priming the diodes.

No flames intended here, but, have you ever flown an RV?????? The LAST thing in the world it needs is spades! Have you ever flown an airplane with spades? Spades are an attempt to make a lesser design fly like an RV. At any speed where you should be leaning on the ailerons, they control forces are very light. As you approach 200 mph they stiffen up a little, still they are perfectly harmonious and the stiffness only serves to warn you that you are smokin at speeds far in excess of the manuvering speed and you might want to push more carefully on all the control surfaces. Remember, an RV is not a "great aerobatic airplane." It does great aerobatics, but attempting to expand it's aerobatic envelope might lead to a bad day. DO NOT put spades on an RV. That of course is only my opinion..... You can do what ever you choose. That is why they call it "experimental." In my humble opinion.... Tailwinds, Doug Rozendaal P.S. If you want to tackle an RV "problem," figure out how to stop the aileron rumble at full deflection. (problem is too strong a word, "slight annoyance" would be better.) ________________________________ Message 30 ____________________________________ Time: 03:19:55 PM PST US From: Chris Subject: Re: RV-List: Aileron spades --> RV-List message posted by: Chris What are Aileron spades? -- Chris Woodhouse 3147 SW 127th St. Oklahoma City, OK 73170 405-691-5206 (home) chrisw@programmer.net N35 20.492' W97 34.342' do not archive ________________________________ Message 31 ____________________________________ Time: 03:36:20 PM PST US From: LeastDrag93066@aol.com Subject: Re: RV-List: Aileron spades --> RV-List message posted by: LeastDrag93066@aol.com I was told that the aileron spades on one aerobatic biplane slowed it down by 5 knots.

Find the aerobatic sites on the web, look at the pictures there. I think they are fairly common on professional aerobatic designs.

Of course you need to prime them. You mean give them a shot of fuel before startup, right? Whoops! Wrong sense of the word. My god man, don't you know corroding diodes could kill us all. But make sure it's an epoxy type or you will have to top coat it within 24hrs. (Place your favorite obligatory smiley here). However, sticking a needle in a less humorous vein, diodes are just check valves for electrons. You always want your catch diodes placed across any DC relay primary (some are actually install internally in certain relays) in a "reverse biased" fashion. If you think about it, if you installed it "forward biased" with +V on the anode (+) and Ground on the cathode (-) (banded side), it would just burn up quickly as many electrons flow from negative to positive thru a low internal resistance (producing lots of watts of heat). Since all of our aircraft (maybe not the Brits') are negative Ground (Earth?), determine which terminal of the relay/contactor/solenoid will be at Ground potential (when +V is attached to the opposite terminal) and attach the cathode (banded side) this more negative terminal. -GV (RV-6A N1GV 575hrs) ________________________________ Message 40 ____________________________________ Time: 08:14:55 PM PST US From: "Eustace Bowhay" Subject: RV-List: Lighter Note --> RV-List message posted by: "Eustace Bowhay" On a lighter note I thought some of you would get a kick out of this if you haven't already seen it. It's the right time of the year Santa's Check Ride It is a little known fact that Santa has to keep his pilot's license current in order to make his deliveries every year, and so the old man wasn't too surprised when he got a letter from the FAA informing him that a examiner would be appearing shortly to run him through the usual recertification drill. A detail of elves was sent out to wash and polish the sleigh, another group was assigned to inspect, service, and repair all the tack,and a third squad started curry-combing the reindeer. Santa himself got out his logbook and the rest of the paperwork and made sure it was all in order. On the appointed day the examiner arrived, and after the ritual cup o coffee, he went over Santa's log and paperwork, then followed Santa outside. After a meticulous review of Santa's weight and balance calculations, the examiner watched Santa do the preflight, then followed behind him, looking closely at everything from bells on the back of the sleigh to Rudolph's nose. When he finished, he turned to Santa and said: "It looks pretty good so far. Let me get one thing out of my bags and then we'll take her up." When the examiner got back, Santa was in the sleigh and ready to taxi. As the examiner climbed into the sleigh, Santa noticed that he was carrying a shotgun. "What's THAT for ?" Santa asked. The examiner looked at him, then winked: "I really shouldn't tell you this, but you're going to lose an engine on takeoff. Eustace A friend sent it to me, to all on the list "Have a merry Christmas".

I had a bag of the small tefzel ties (expensive) and they would burn and melt with a flame. Yes, I tested them. I did not compare actual melting points etc., but felt the extra expense was not worth the percieved, to me, gain in safety/quality. In the rear of the fuselage use nylon tubing, spiral wrap, or nylon ties if you want. Just be sure to propely secure, size, and protect circuits like others have posted. Do not use electrical tape.(unless you really want to) It can unravel, leaves sticky residue and looks unprofessional. (in my opinion) Again, if my wires ties or plastic wrap (which I do not have) in the rear fuselage are hot enough to put out serious fumes I will wish I had a chute, just in case. > > If my wire ties are giving off enough fumes to cause a problem > > I will likely wish I had a parachute.

I later purchased "Michelin Air" 600-6 tires and not only would they not fit the the opening but the entire fairing was too narrow to enclose this beefier tire. My finish kit contained "Aero Trainer" tires, the same brand which I once equipped my plane (Cessna 170) with while my wife was learning to fly and could not get them to last until she soloed!! Beware, tires are not equal just because they have the same size/ply rating.
