    Subject: Question for the aerodynamycists
    --> RV-List message posted by: "Richard Bibb" <rebibb@comcast.net> I am going to install a NACA vent on the side of the forward fuselage on the RV-4 I am rebuilding. I am thinking of installing it right below the cowl cheek angled downward so that the longitudinal axis of the vent is parallel to the logitudnal axis of the cowl cheek extension. My thought is the pressure will be positive in this area and will result in good positive airflow into the vent (this will be for fresh air ventilation to the front cockpit). I assume that the left side will be best for airflow given the vortex generated by the propeller but the right side would be best for internal routing of the scat tubing as there is no throttle and mixture control cables to avoid. Does it make an appreciable difference? As in most things the best idea would be to try it to find out but that is not practical given the hole I need to cut in the fuselage skin. I'm looking for opinions and/or experience with this location. Is my thinking sound or am I missing something? Net, net - I'd like to install on the right but the left seems like a better location. Which is best and will either work? Richard RV-4 N144KT - rising from he ashes of a 1998 landing in the trees at IGX.

    3.3 DATE_IN_FUTURE_12_24 Date: is 12 to 24 hours after Received: date --> RV-List message posted by: "Steve & Denise" <sjhdcl@kingston.net> Exactly. Why anybody would build a $60,000 airplane and finish it off with a $4000 engine is beyond my reasoning. The most important piece of the puzzle and I see way too many builders trying to find the cheapest they can get. If I have to spend $35,000 to get a good engine either new or a very well documented log books then so be it. Wheres the checkbook? If anyone buys an engine like this the amateur built warning sign should include the price paid for the engine in large capital letters. As the saying goes: If you can't afford a good engine, you can't afford an airplane. Ebay is for digital camera batteries, not aircraft engines.

    Subject: Re: Saw this engine on Ebay
    --> RV-List message posted by: "Ronnie Brown" <romott@adelphia.net> Please don't perpetuate the myths about this engine. I ran two of these O320-H2AD engines to TBO on our 1977 Cessna 172N with ABSOLUTELY NO internal problems. There were indeed problems with the early engines at a time when these engines were not flying much due to the oil embargos of the 70's. I also have a friend with this engine installed on his RV-7A, with over 500 trouble free hours and he is very happy with it. See the bottom of page http://www.prime-mover.org/Aviation/C172.ENGINES.html for more info on the truth (not myths) about this engine.

The $3,500 is probably less than the value of the good parts on the engine. Its less than the cost of a case alone, for example. The H2D had a bad reputation as early versions had problems (can't remember what they were but I think CAM and/or lifter related. Later serial numbers fixed those problems and it became a very reliable engine. For $3,500 youcould buy this engine and overhaul it by having the parts sent out for yellow tag inpection and refurb/replace for 5-$15,000 depending on what needed to be scrapped. I'd have a hard time buying it sight unseen and would want to at least pull the cylinders to get a look at the cam and dial the crank but it is a good deal if anything major is salvageble. But if you would rather convert cash to an new engine that is also a very wise choice, maybe even a preferable one. There has been a lot of talk on how much it cost to build one of these things. That is inversely proportional to the amount of work you want to do scrounging for deals on used stuff versus buying brand new out of the box. Of course new is better, but a flying aircraft can be done safely and a heck of a lot less cash out the door. Of course this assumes you pay yourself the kind of wages tyrants the world over pay their minions...

    Subject: RV-8 Canopy Track Question
    From: Don.Alexander@AstenJohnson.com
    08/20/2004 09:12:07 AM --> RV-List message posted by: Don.Alexander@AstenJohnson.com I am in the process of putting my C-804 / C-805 rear slide track together and have run into a question that I can't seem to find the answer to. The plans indicate that the 805 should be countersunk on both sides for the AN 426 rivets. I don't understand what this means. How does one go about driving the rivets on this assembly? I imagine that the shop head of the rivet somehow nests inside the bottom countersink, but I don't see how to drive the rivet down into a "funnel" shaped hole.

    Subject: Re: RV-8 Canopy Track Question
    --> RV-List message posted by: Tailgummer@aol.com Don, it's reffered to as " double countersinking". Just countersink each side as usual then select a rivet length shorter than you would use to produce a shop head and squeeze. Try it out on scrap to get a feel for the correct length. The final result is a smooth surface on both sides. It might not be perfect, but it will work. John D'Onofrio

    Subject: RV8 one piece wings skins
    From: "Stewart, Michael (ISS Atlanta)" <mstewart@iss.net>
    --> RV-List message posted by: "Stewart, Michael (ISS Atlanta)" <mstewart@iss.net> I just found out from Charlie Kuss, builder in Fl., that Vans now can make for you single piece wing skins, .032 in stead of 025, for the RV8. I am a little upset (OK A LOT) I did not know about this. Up charge is some $50 or something, negligible shipping charge change. Many of you probably know that when you sight down the wing of any RV with 025 skins, you see the dip between the ribs. Unsightly. Weight penalty is about 4lbs total for the plane using the 4 new skins. Im no aerodynamicist but Ill bet that the speed increase is more than negligible with the lack of distortion using the 032 skins. I sure would have liked to have known this on the Super 8. I'd of taken that penalty for strength in a heartbeat. Thought you all would find this interesting. I have not spoken to Vans yet about this so I can not confirm the cost or availability. I would also be interested in knowing what strength increase could be expected from a change from 025 to 032 skins if anyone happens to know (or swag) this off the top of their heads. Regards, Michael Stewart All my list watching did not turn up this info. ARGH!

    --> RV-List message posted by: Phil Birkelbach <phil@petrasoft.net> Wow, beyond reasoning? I don't think I'd consider a $4,000 engine much more than a core but if it's a good core and the crank, cam and case are good you're only about $8,000 away from a good rebuilt engine. If I had been able to find an engine for $12,000 then I wouldn't have a $60,000 airplane I'd have a $40,000 airplane. If it were me I think I'd start looking east. There are about to be a bunch of perfectly good engines coming out of bent up airplanes in Florida. A guy here in Houston built a $28,000 RV-6 (8 years ago) and part of his secret was a hurricane engine.

An -8 canopy can be opened in flight - not sure about any others. What would be bad enough? Not sure. If there was fire in the cockpit, it wouldn't take much to get me out. Inside the cowling - probably depends on how hot my feet are getting and what kind of emergency landing spots are or the ground below. As for someone actually able to get out of the plane (RV-8), it is possible and has happened. Unfortunately, a contributor to the list, Mr. Von Alexander, exited the plane without a parachute and did not survive. As I remember the discussions, it wasn't exactly clear as to why he had the canopy open and was unstrapped. Check the archives here and NTSB records for more info. http://www2.ntsb.gov/ntsb/brief.asp?ev_id=20001212X19358&key=1 Bryan Jones -8 www.LoneStarSquadron.com Houston, Texas > > Bryant: Thnaks for the reply, however, two things, what do you do >in >case of fire, as you said, how can one open the canopy in flight, and when >is >the fire bad enough to get to this situation? > >Second I really would like to know if there is any record anywhere, as to >has any one ever, to use the word, egressed, from an rv in flight? > > >Thnaks > >Bert >

I try to stay out of things like this but.... Is aviation the exclusive domain of the rich and privileged? $35,000 is more than some people make in a year. Does this mean they have no business building an airplane? There are other alternatives and buying this engine as a core for rebuild may be an affordable alternative for some. Not all builders have an unlimited chequebook allowing them to quickly assemble a quickbuild plane. Some whom could afford it, still prefer to build every piece themselves, which may include rebuilding the engine. They may be capable of superior workmanship... would they still require a warning sign including engine price posted on their aircraft? I was able to find my low time 13B engine core for $160CAD. How does that make you feel?... no wait, I really don't give a damn. I don't want to start a flame war here, but just want to make sure we don't climb too high on our aviation pedestal as this attitude makes us targets. Now that I own an airplane people seem to think I'm rich. Rich yes, but certainly not in money. do not archive S.

    (not processed: message from valid local sender) --> RV-List message posted by: "Matt Johnson" <matt@n559rv.com> One of the guys at Sierra Skypark here in Fresno has a dimpler that is a floor standing pnuematic dimpler with a foot pedal that he uses to dimple skins. I noticed that his finished control surfaces has no light distortion around the rivets at all (showing a slight dimpling that extends past the rivet head). When you look at his rivets, you would think they were countersunk in the skin not riveted. My question is, is that from his technique at dimpling skins or is it because he has the pneumatic dimpler? My rivets look pretty good, but not that good and I use the standard bench top one that you pound with the hammer... By the way, were do you even get a floor unit like that? I looked online and cant find one. - Matt

You can probably find a rebuilt one from different dealers for the $5-6,000 range.

    Subject: Buying a used engine
    0.3 SUBJ_BUY Subject line starts with Buy or Buying --> RV-List message posted by: "Eustace Bowhay" <ebowhay@jetstream.net> I have bought used engines in the past and have had fairly good luck. From experience I have set myself some guide lines and will pass them on to the list hoping it will help someone and maybe save some heart-ache. I divide the engines into three categories, part time first run that can be put into service without overhaul, part time second run and high time. My first choice is first run part time with good logs that can be verified and the same for second run but must have been overhauled by a reputable overhaul facility and the logs to include a work sheet and parts list for the overhaul. The high time engine is a core only and will be overhauled. The value of the part time engines is based on time on the engine. The value of the high time engine is a guess, it may make a good core or could be a good boat anchor. When I bye a part time engine I take it to a reputable overhaul facility (in my case this would be Aero Sport Power) and have it checked out and run in their test stand. For me this is a must, for safety sake and fairness to your passengers you have to know you have a safe reliable engine up front. In years gone by I have worked in a engine overhaul facility and understand the overhaul process, but am a firm believer in getting my engines overhauled in a good facility. This becomes even more important now with the RV 10 since we will be carrying three passengers. Van' choice of the I0 540 for the 10 has to be the very best as it is one of the most reliable engines ever built. Eustace Bowhay RV 10 40030 Working on the fuselage

    Subject: Re: Park brake
    --> RV-List message posted by: "Richard E. Tasker" <retasker@optonline.net> Okay guys, let's not get too carried away. If you look at the operation drawing on the website, you will notice that the operational arc of "on" and the operational arc of "off" is everything except the middle 45 degrees where it is transitioning. In other words, all this discussion about 45 or 90 degrees is just smoke. If you look at the drawing you will see that the valves are fully open everywhere from about 27 degrees above horizontal to completely vertical. They are fully closed from about 25 degrees below horizontal to completely vertical (down). So, as long as you don't leave the valve in the central position (approximately +/- 25 degrees) you are fine. With the way it works, you cannot turn it on when you really want it off. Unless you have some really funky linkage you can only pull or push to the vertical positions and all is well. I suppose you could overcenter the lever and have a problem, but even there, assuming you have the clearance for the lever movement, the valve would still work properly. Stops are nice but not really necessary for the proper functioning of the valve.

    Subject: don't want the engine to fall off.
    --> RV-List message posted by: "thomas a. sargent" <sarg314@earthlink.net> I'm surprised that the manual says very little about attaching the Dynafocal II engine mount (for RV-6A) to the fuselage. I could use a little guidance here. The pre-drilled bolt holes in my QB fuselage are 1/4", intentionally undersized for the 3/8" bolts in the engine mount. My plan is to get a couple sholder bolts that are 1/4" in the threaded section and 3/8" in the shank and see if I can use those to center the mount on the plane, or at least find a resaonable compromise position. Then using the engine mount as a drill guide, drill the holes out to size with a drill slightly less than 3/8". Then ream the hole out to 3/8". (My mechanical engineer co-workers tell me that reamed holes are significantly stronger.) Is this what most folks do? Or am I missing something obvious? Proceeding carefully here... botching these holes would be REAL BAD. -- Tom Sargent, RV-6A, Landing gear

    --> RV-List message posted by: "Jim Jewell" <jjewell@telus.net> Hi Tom, I built the slow built 6a and did pretty much what you describe. Instead of shoulder bolts I used some bushings on 1/4" bolts. I centered the mount over the two holes that gave me the best average fit for the rest of the holes and bolted the engine mount down. I then used some more bushings to re-center drill the remaining slightly off center firewall mount holes. Next I used the mount itself as a guide to drill the fierwall holes to final size. The reammer sure can't hurt, weather or not it is needed in this case I'll leave up to the experts to have fun with.{[B-)! HuH!, quick build EH! (;-)!
