I don't have pictures with me that show the top bolts but if you look closely at the pictures on my web site, you can see where the notch at the bottom of the rib allowed room and I believe it was the same at the top of the spar: http://rv6aproject.ckhand.com/panelAndElectrical/electrical/electricalPg7 .htm You can see in the pictures that I installed most of the bolts with nut on forward side (was easier for me to torque properly and I expect easier to check torque later) but where those ribs interfered, I went the other way around because I couldn't get the bolt in straight from the back. I think it was just the center two floor ribs I had that problem with. Chris RV-6A ----- Original Message ----- From: thomas sargent To: rv-list@matronics.com Sent: Friday, April 17, 2009 10:49 PM Subject: RV-List: wing root bolt interference I am bolting on the right wing on an RV-6A quick build for final assembly. The second NAS 3/8" close tolerance bolt out from the center on the top will hit hit a floor rib. I slipped a hardware store bolt in there and it has about 3/16" clearance between the forward edge of the floor rib and the aft surface of the steel splice plate. Am I supposed to install this bolt backwards or chop away the offending portion of the rib? Even if I install the bolt with head aft instead of forward, it would be very difficult and probably do a lot of violence to the rib. The edge of the rib isn't squarely aligned with the bolt center, but it's pretty close. The rib would have had to be installed about 1/2" further outboard to not be an issue. I could chop out the offending portion of the rib and then rivet in a patch later. What do they expect me to do here? -- Tom Sargent ________________________________ Message 2 _____________________________________ Time: 07:06:02 AM PST US From: "Ron Lee" Subject: RV-List: Where is the fun in straight and level? > Where is the fun in Straight and Level?? :-) > > GummiBear > Upside down on almost every flight. > Harmon Rocket II - N561FS Bahamas, Key West, swim with manatees, Page AZ, Devil's Tower, Mount Rushmore, Catalina Island, Yosemite, Carlsbad Caverns, Meteor Crater, Monument Valley, Death Valley, Saguaro NP, plus many more.....all without going upside down.

From: J Riffel I flew my RV7A for the 1st time 12/12/08 (after 4 yrs) and have about 55 hrs on it. I chose a AeroSport IO-360 and decided on 2 PMags for ignition. I also have an old '65 Mooney w/ Slicks (for comparison). I chose the PMags because: 1. It's electronic ignition - which I believe delivers better ignition than mags 2. The "P"mag version eliminates the need for a backup battery/generator/alternator a. I put 2 PMags on for redundancy (for the engine to stop all of the following would have to fail: alternator, battery, and BOTH internal PMag generators - which was good enough for me) 3. They allow me to use $2 auto plugs vs $20 aviation plugs (required their inserts/harness at reasonable extra charge) 4. The timing process takes less than 20 seconds and requires no equipment (you turn on power, set #1 on TDC and blow in the vacuum line a couple times) (My FAVORITE BENEFIT after timing my Mooney Mags) a. A friend had another electronic ignition that failed on an Alaska trip and had to call back to Texas and get his special timing box sent. 5. There is no tricky mounting (just bolt them on where the mags go) in any orientation. 6. They deliver a tachometer signal for my GrandRapids EIS 7. Because they don't have wear issues, the long term maintenance issues seem small (if there are any) 8. They're priced competitively Issues: 1. None- they started right up the 1st time and have run flawlessly. Concerns: 1. They're experimental so we might be working thru problems together a. Their approach/concept seemed like a 'better idea' to me than their competitors b. I met the folks at OSH and visited their shop here in Texas and felt I could trust/work with them; besides the benefits seem to outweigh the concern (for me) c. I've gone thru a sofware update (before 1st start) and the magnet attachment change (at about 10 hrs). They were great during the process. 2. They've had some issues on the software side and hardware side a. They've been open about problems and addressed them quickly - and seem to have been stable for quite a while 3. The process to hand-prop the engine is a little clumsy - but I haven't spent enough time thinking about how to address it (I had a battery go down/out during my fly off hours - thank goodness a friend was able to fly a battery and tools to me - BTW: Carry Tools!) I'll probably talk to them at OSH this year 4. My engine temps have been on the high side so I changed them to use the alternate internal "curve" (put a jumper on 2 terminals) - and I'm not sure what I believe yet whether the PMags, new engine or both are affecting temps ... or whether it's an issue 5. Not really a Concern, but I'm not that fond of the plug on the unit that you put wires into. It works fine - but I'm not sure what the long-term vibration will do to the wires at the plug. You'll probably want to read the posts on Matronics and VansAirforce about ignitions - and Pmags. Some aren't happy. I am.
