    Subject: RV6A Nose Gear Fairing Question
    --> RV-List message posted by: Greg Grigson <iflyhawaii2@yahoo.com> I'm wrapping up my RV-6A finally! I can't find Figure 10-10 in my RV6/6A instructions (which are eight years old by now). Am I missing anything earth shattering or will I eventually figure out after a few days thought? The figure is referenced in the COWL/NOSE GEAR INTERFACE section on page 10-9 (last page). Thanks in advance. Greg Grigson Honolulu __________________________________ Find restaurants, movies, travel and more fun for the weekend. Check it out! http://discover.yahoo.com/weekend.html

    Subject: Re: Filler durability
    --> RV-List message posted by: "DAVID REEL" <dreel@cox.net> Filling all the rivets seems a bit extreme. My painter didn't have any problem using Imron. Five years & 900 flying hours later the paint is in excellent condition. Has anyone actually seen a problem with Imron adhesion around the rivet heads? My inquiry about filler durability was prompted by painting a 'spare' rudder. The test paint job showed dark rings around many of the rivet heads where the imron did not flow over the gap. It wasn't a cleaning problem because the primer flowed into the gap fine but didn't remove it enough everywhere for the imron to bridge the gap reliably. Dave - RV8A

    Subject: Re: Filler durability
    --> RV-List message posted by: "Richard Crosley" <rcrosley@adelphia.net> I used Imron paint and agree it does not like to flow across the rivet. I like the look of the rivets so used spray can primer before painting. Spray the rivet line and wipe it off with a credit card. The primer is forced down into the little rivet crack and the Imron flows nicely across the rivet. If you want the rivets to go away entirely then you'll have to use a filler and do a lot of sanding, and push your first flight back a month or so. Rich Crosley RV-8, N948RC

(which is why the smaller engine cowls look so much nicer, IMHO!) The total shape of the inlet/exhaust blister may affect flow out the rear- curious if you could get actual inlet/outlet area for the 360 cowl and compare size & ratio to yours? Also, maybe it would be easy to rig some kind of stand-off(s) from the bottom of the firewall down to the edge of the cowl outlet to hold it open a bit wider? Should be easy to do, might just try that myself! Could be an easy comparo to quantify effects of cowl outlet size? Mark Phillips do not archive

I just resorted to a small aluminum plate, wider than the slot and shaped to match the rear of the leg fairing, with a couple of platenuts on either side. Screws go up through the cowl into the platenuts. I added epoxy/flox/microballoon mix to fill the gap on the plate between the cowl edges, sanded flush with the cowl. Four screws and it's off.

I like the look of rivets, too, but I've seen some problems with dark colors. Wax or polish sticks in the rivet or along the edge of the rivet, and stays white. I guess flushing up the rivets might help. I'm a ways away from worrying about this, but it never hurts to plan ahead. -- Mickey Coggins http://www.rv8.ch/ #82007 Wiring

    Subject: New to the group
    --> RV-List message posted by: "Richard Leach" <papadaddyo@verizon.net> Hello all. My name is Rick Leach and I am a new builder. I actually have had my RV10 empennage kit for about a month and finally got to start on it a couple of days ago. Real humbling for the first step to be cutting out stock. Several questions if anyone can help. What is the best way to cut the thicker pieces of stock and two, I have 2 part epoxy primer but there are no mixing instructions. I am assuming that it is equal parts of A and B. My questions may be basic but I believe in the old saying that the only dumb question is the unasked question. I am sure I will have many more. Thanks all, Rick #40397

If'n ya ain't got yerself a bandsaw yet, ya best git shoppin! Of course, they may not be as useful for the newer kits, but I sure busted out lots of parts on mine for my -6A slo-bild. Most useful was a real skinny (width-wise) metal blade, about 8 or 10 teeth per inch IIRC. Works great for anything from .025 sheet and thicker. Also works good for plastic, wood, fingers etc. 8-) Alternately, you could use a cut-off disc in a die grinder, but take care you don't toast yer fingers!

I owned a -4 for about 7 years that had filled heads on the top of the wings. It wasn't heavy (932 lbs) & it was fun answering questions at flyins & airshows.

    From: "RV Builder (Michael Sausen)" <rvbuilder@sausen.net>
    --> RV-List message posted by: "RV Builder (Michael Sausen)" <rvbuilder@sausen.net> Nope, nothing official to back it up other than my feeling that this relates to the pre-GPS regs and was never really updated. Of course I could be completely wrong. I also expect EAA to error on the side of caution when interpreting regs. Nothing wrong with that. I would love to hear the "official" FAA answer on this but we all know that the only official FAA answer is that the answer changes depending who you ask. Either way I will have normal VOR based NAV equipment as I will never 100% trust GPS until someone makes it jam proof. Low power signal in LEO = fairly easy to overpower. I want to be able to reference a ground based NAV whenever possible, especially on an approach. Reminds me of the story of the former Russian scientist walking around the Paris airshow trying to get someone to buy his GPS jammer that was built out of spare parts. Of course I heard that from a friend who heard it from a friend so take it with a cup of salt. But this is probably also the reason the gov is getting ready to completely overhaul the GPS. Guess that means another round of expensive avionics upgrades in 10 years. ;-) My 2 cents and oh ya, DO NOT ARCHIVE.

I would sit down at the computer with your A and B cans of primer and do some searching on google for the manufacturers web site and find the details of that particular hardener and epoxy. Be sure you are looking at the specs for the exact product you have, some manufactures have different hardeners for the same epoxy resin that require different mix ratios. -- Chris W Gift Giving Made Easy Get the gifts you want & give the gifts they want http://thewishzone.com

    --> RV-List message posted by: Tim Olson <Tim@MyRV10.com> Rick, Glad to hear you're started on your tail kit. Don't worry, after a few sessions you'll get into the swing of it. I found the easiest way to cut most things that are in the kit is a bandsaw. I got a cheap Harbor Freight 12" model that is currently $109.99. I wouldn't go any less than a 9", but larger is nicer. The bandsaw will be used a LOT of times during the process. I also bought an air powered cutoff tool, that is nice for cutting some things. Between those 2 items, 95% of my cutting is done. You didn't mention your primer brand and type. Not all are the same. I'm using AKZO from Aircraft Spruce. It's a 1:1 mixture. I don't get overly precise...I just have 2 measuring dip cups and I take out equal numbers of cupfuls of each. Works well for me. One other suggestion for you. This RV list is fantastic, but you should not forget to join the other RV10-List on the Matronics page too. It's on the same subscription page on Matronics site. You can post this type of question there and if you reference specific parts, there are many of us who have been through what you're about to take on.

    --> RV-List message posted by: "Tim Bryan" <flyrv6@bryantechnology.com> Rick, When looking at band saws, make sure the speed will slow down to about 300 or so. Also make sure you can get a metal cutting blade for it that is good for aluminium. Makes a big difference. My first bandsaw would not slow down and did not work well. I bought a variable speed saw from sears and love it. Slows way down and they have a non ferous metal cutting blade. Works great.

My name is Rick Leach and I am a new builder. I actually have had my RV10 empennage kit for about a month and finally got to start on it a couple of days ago. Real humbling for the first step to be cutting out stock. Several questions if anyone can help. What is the best way to cut the thicker pieces of stock and two, I have 2 part epoxy primer but there are no mixing instructions. I am assuming that it is equal parts of A and B. My questions may be basic but I believe in the old saying that the only dumb question is the unasked question. I am sure I will have many more. Thanks all, Rick #40397

I'll use weather stipping of some type inside to help seal the air gap. I did use a metal shrinker of the top frt. edge to help it fit better. Not sure if I want to try that on the rear bottom though. -- Surfing the Web from Hopkinsville, KY Visit my web site at: http://www.geocities.com/hester-hoptown/RVSite/ RV7A Slowbuild wings-QB Fuse :-)

    --> RV-List message posted by: Larry Olson <lolson22@cox.net> For Sale Engine & Prop Firewall forward off a RV6 All included except engine mount. Lycoming O320-A2A 160 hp 200 hrs SMOH Absolutely everything was done at overhaul Balanced pistons, rods and crank All AD's complied with. Spin on oil filter. New Slick mags and harnesses. Vacuum Pump Vetterman exhaust Van's filtered air box w/alt air Carb Van's throttle and mixture bracket Van's 35 amp alternator Sky-Tec starter Heat muff Baffling Oil cooler & oil lines (oil cooler mounted LR baffle) Fuel Pump Engine runs great Can accept a CS prop Sensenich FP Prop 70CM6S9-0-80 Van's spinner (true to .004) Spinner painted Sherwin Williams AcroGlow White If purchased before my new 200hp arrives you can hear it run and take a test flight. My RV6 with this set up cruses at 185 mph and climbs at 1500 fpm. I never had any heat issues even in 100+ summers in Arizona. I took very good care of this engine. I have all records and oil analysis. I changed the oil after 10 hrs then at 25 hrs then every 25 hrs after that. This is a great set up and will cut hundreds of hours off your build time. Think about it, all of the bugs have been worked out. You won't have to build the baffle!!! I am replacing the engine and prop with an IO360 and a CS prop. $20,000 fob Phoenix, AZ Larry Olson

    (not processed: message from valid local sender) --> RV-List message posted by: "Matt Johnson" <matt@n559rv.com> I have built an AOA that uses differential pressure. It is interesting that you mention violating AFS or Dynon's patents since I know that the process of using differential pressure to determine AOA is not new. The airlines all use it.
