    All, Even though I'm only 70% done with the tail kit, I've been thinking a lot lately about wiring. I'm about to order Bob's book, but I'm asking you guys, the ones who've never done wiring before (except minor home repair), what other sources, if any, do I need to buy to get a foundation on simple schematic reading and building up from there? I don't know of any SportAir workshops any time soon in my area (lower AL) on the subject. Or will Bob's book start me out right? Rob #392 Short break between HS (61 hours) and Elevators.

    Bob's book covers a lot of theory, as well as providing some rock solid system diagrams and suggestions, but it doesn't really teach you the hands-on techniques. How to use crimpers on various pins and sockets, how to solder this and that. A lot of the fundamentals it just kind of assumes you have already. If you need "from square one" type instruction, I suggest getting together with somebody who has experience and tools and can show you the ropes. Something else to consider would be to scour every bit of the articles here: http://www.aeroelectric.com/articles.html Lots to be learned there for the uninitiated. Great stuff. )_( Dan RV-7 N714D http://www.rvproject.com ----- Original Message ----- From: Robert G.

    Hi Robert! The book will give you all the theory you need. However, you will need to do some practice soldering .... just as you did riveting! The secret to good soldering is a good temperature controlled iron and the right shaped tip. My favorite is an old Weller soldering station. The tips are temperature controlled and there are many shapes to choose from. Easily changed (even when hot), each tip has a number stamped on the bottom .... for the temp. #7 is 700 degrees and #8 is 800 degrees. I prefer the long pointed tip to do connectors with. I also use the #8 tip to get in there, heat the joint and add solder. Never, never carry solder to the joint. You need the flux to clean the joint and get good solder flow. My best 'secret' is a rubber sleeve from an alligator clip. When you strip the jacket of the mil-spec wire, all you have to do is cut the jacket (Paladin makes a neat tool to cut jackets and insulation .... surestrip), insert the wire into the small end of the rubber insulator, squeeze and pull. Comes right off. That stuff is more slippery than snot, but this works for me. As for schematics, you won't have to learn many symbols .... and most are named anyway. If you see a symbol you can't understand, then just describe it to the list and someone (or many someones) will educate you. I can't think of many ... battery, motor (starter, trim and flaps), relays, switches and some resistors (maybe), mike and phone jacks, ....... I'm running out of ideas here! :-) Good questions though!!! Linn (NASA certificated solderer) do not archive Robert G.

Electric Bob also holds weekend workshops that cover the same material as his book, but can help you to see the big picture. I went to one in Camarillo when I was building the -7A and it helped quite a bit. When I read the book and looked at the schematics, I didn't get the Eureka effect until I realized that every time Bob refers to a bus, what he really means is a fuse block. Main bus = 10 position fuse block in my -7A, Essential bus = 20 position fuse block. Once you get that, the rest of it is just point to point wiring with the correct AWG wire size. -Dan Masys RV7A N747DL flying RV10 rudder

    Subject: Minimum practical runway length for an RV-10
    --> RV10-List message posted by: Dan Charrois <danlist@syz.com> Hi everyone. I've recently decided to join the ranks of RV-10 builders, having ordered my tail/emp kit a week or so ago. It's due to arrive some time next week, and I'm excited to get started. There are a couple of airports within a 30 minute drive that I could base the plane out of (and finish the construction at when it gets too big for the garage). However, I would much prefer to be able to keep the plane at home if it's at all practical - to benefit both the construction process as well as operating the plane later when completed. Having the plane literally just outside the door when I want to go flying would be a huge contributor to "just because" flying. So ideally, what I'd like to do is build a hanger at home and a grass strip. But I have some questions. First of all, how is the RV-10 expected to be able to handle a grass strip? Secondly, what would a "practical" runway length be for such a strip? I've read the fully loaded specs with a 260 hp engine (which I'm planning for) to be 500 ft takeoff and 650 ft landing (and in the factory demo ride I recently had, I can believe those numbers). But of course, that's assuming a perfectly performing plane, hard surface, etc. The land we own is approximately 2500 feet long, but there are several houses adjacent to the far south end. Because of this, I would plan on using it as a one-way runway to the north, to minimize any disturbance to the people there (takeoffs would be away from the houses, and landings over the houses to the strip would be at low power). Fortunately, there are no obstructions at all towards the north, nor are there likely to ever be - just flat field for miles, and the prevailing winds would almost always favor a northerly takeoff/landing anyway. To minimize the disturbance to our southern neighbours, I was thinking of a runway about 1300 feet long at the north end of the property, so there would be about 1200 feet between the houses at the south end of the property and the threshold. There is about a 0.9% gradient uphill towards the north. Obviously, the gradient and grass strip would reduce performance from the quoted figures, but I'm wondering what you folks out there would consider "appropriate" from a safety standpoint. Would this work? Also, how wide of a strip would be practical? I've landed at countless 75 foot wide strips, but would 50 feet wide be okay? Of course, the longer and wider the better, but I'm looking for practical minimums here, which I would probably increase a bit anyway. The other question pertains to our climate up here in Canada - for a large part of the year, the ground is covered in snow. Clearing the snow wouldn't be too much trouble - we can borrow the equipment for that. But not having landed anything on a grass strip with a plowed snow surface, would I just be asking for trouble? Or would it be better to fly in the winter with skis and forget about plowing (in that vein, could skis be outfitted to an RV-10?) The two airports within 30 minutes are both maintained summer and winter with asphalt runways, so I could always use them if returning from a flight somewhere and conditions at home aren't conducive to a safe landing. And of course, if operating an RV-10 out of a grass strip with the limitations I've mentioned isn't practical, I may be basing my plane out of one of those airports anyway. But since it would be so much more convenient (and less costly) to keep everything at home, I thought I'd write for advice on the matter. Thanks for any help you can give!

My inspector was not sure if it was the spars or other riveting on fast build wings that was the issue during the pre-close inspections. I'll be following this up when I get home next week and report what ever I learn but with some luck the guys that had the problem are on the list and will set the story straight. The other thing I plan to do is get out my calipers and be sure the tails of the spar rivets are driven enough to meet *MIL-R-47196A * (found a copy at: <http://home.flash.net/~gila/rivet_spec/rivet_a.htm>)* *Perry Casson Chris , Susie McGough wrote: > --> RV10-List message posted by: "Chris , Susie McGough" > <VHMUM@bigpond.com> > > Perry this is of serious concern...do you have any more details as I > would like to follow it up at Vans.

When you strip the jacket of the mil-spec wire, all you have to do is cut the jacket (Paladin makes a neat tool to cut jackets and insulation .... surestrip), insert the wire into the small end of the rubber insulator, squeeze and pull. Comes right off. That stuff is more slippery than snot, but this works for me. As for schematics, you won't have to learn many symbols .... and most are named anyway. If you see a symbol you can't understand, then just describe it to the list and someone (or many someones) will educate you. I can't think of many ... battery, motor (starter, trim and flaps), relays, switches and some resistors (maybe), mike and phone jacks, ....... I'm running out of ideas here! :-) Good questions though!!! Linn (NASA certificated solderer) do not archive Robert G.

I'm about to order Bob's book, but I'm asking you guys, the ones who've never done wiring before (except minor home repair), what other sources, if any, do I need to buy to get a foundation on simple schematic reading and building up from there? I don't know of any SportAir workshops any time soon in my area (lower AL) on the subject. Or will Bob's book start me out right?
