A couple of things upon which to comment. First, I didn't think I would be coming to (going to) the AYA convention this year. I hadn't planned for it. I bought a house last year and I'm still recovering from the down payment and remodeling. SOOOO, I didn't read the Star articles regarding the venue in Dayton. I mean, why should I? I've been going to conventions off and on since 1990. They are all pretty much the same. They start on a Monday, banquet dinner on Thursday, fly home on Friday. Clytie, my better half, had never been to a convention. I tried explaining what it was like. No luck. You had to be there. Then, one night after the Red Bluff Fly-in, while sitting by the waterfall in the living room and watching TV, my better half said, "Let's go to Dayton." She wanted to fly 28747 to Dayton. She's quite the adventurer. She loves flying too. We started doing the math. I don't owe Garner that much! She said, "Let's go commercial." The blasphemy. "OK." Within the next 30 minutes, she on her iMac and me on mine we searched for good deals. We finally found round trip tickets for under $800 for both of us. I filled out the application for the convention, made out a check to Karen and Stew who had dinner on me (just kidding), and began planning for the event. A few days later, talking to Roscoe, I learned the "experts forum" was on Friday. "Doesn't the convention end on Thursday and everyone flies home on Friday?" Not this year. When I got my 'information' package from the 'home office,' I opened and started reading. Blah, blah, blah. WAY too much gibberish and nonsense and not enough real content and information. If one keeps the previous years' package, you'll recognize it. Case in point: The colored chart with the schedule of events. 3 point font? are you kidding? What was the point in the colors? There was no color code to say what was what. Or was it colored to make it look important? I couldn't tell. And, the "Seminar" schedule. Seminar? Where on the colored sheet did it say what the seminar was? Short of going to the room where the seminars were held, it wasn't obvious to me. But, it was done in Excel. The schedule: There are times when I just wish people would quit using Excel to do data bases and text outlines. Excel is for spread sheets. Doing anything more with it tells me you need to get out more. Oh, I know, you got Excel as free software when you bought your first PC in 1984 and, by damn, it'll do everything you'll ever need. The schedule, neatly boxed in with every line having its own border, had the same information as the colored page but in slightly more depth. Why not spend a little extra time and a word processor to make something that looks like a schedule? Transportation: There was no transportation to and from the Dayton international airport. I guess if you don't fly your own plane in you're not worthy. A big thanks to Hal and Vickie Beauchesne (Bow-Chez-Nee) who made two round trips to pick us up on Sunday. And, an even bigger thanks to Garner for getting up at 4am and taking us to the airport Friday morning. Then there was the shuttle, to and from the little airport, hosted by my buddy Mark Matthews. Clytie and I bummed a ride to a fish restaurant (seriously, does everything in the midwest NEED to be fried in butter?) with Mark and Kelly. Both were very gracious and friendly. Clytie sat next to Kelly and a casual observer would have thought they had known each other for years. Mark, I take back everything I've said. The Air Force Museum: No where, anywhere I looked anyway, was there ANY information on the experimental planes at the Museum. On Wednesday, we got there early so we could have time to look at the planes. The first thing I asked the person at the information desk was, "Where are the experimental planes?" Pointing to her right, "Out that door and that way." Asking another face in the museum, "Just keep going to the end. They are past the B-2." Well. Not exactly. The X-planes are on the other side of the base and you need to be military or go on 'the short bus' to get there. How do I know? We went back on Thursday (we stole a car and used the GPS in my iPhone to find the museum). We got there 10 minutes after the LAST bus to the X-planes left. But, "it was full anyway. So, you still wouldn't have been able to go." says the new guy in the information desk. Seems to me, someone putting on a show in Dayton for pilots would have spent more time arranging these excursions. The museum could have spent more time with signs explaining the lock-down on X-planes. New and old friends: Wow, where to start? Garner, Mini, and the kids. They are like family. I've known them longer than any of my marriages; in fact, longer than all of them combined! It was Celise's birthday on Thursday. That was fun. It was great seeing Ian, we talked about taxes, and Nigel, now I know why he's called Grumpy. Charlie and Carol Adams. Gil and Doris. Claude Allen, Patrick/Theresa, . . . . Wow, looking over the list of attendees, I count no fewer than 45 people who we saw and talked to who I already knew. We also made several new friends. John Betsill who spent 30 minutes chewing me out for saying the YF-23 was better than the YF-22 (he overheard me saying that to Dave Fletcher). Turns out he was an engineer on the YF-22. Oddly enough, since I worked with a good many of the folks who went on to test fly and develop the F-22, we knew many of the same folks. John, I still think the YF-23 was better. Bob Hodo and I carried on like we've known each other for years. And, of course, my new friend Mick Beede, who gave us a ride to the Air Force Museum in exchange for a 60 minute dissertation on what to do and not to do if he wants to replace his own windshield. The most interesting experience was observing behaviors. I guess I had noticed before, but it never totally sunk in. Ron Levy, walking toward me, did an abrupt "eyes right" about 10 feet before passing in an effort to avoid eye contact I guess. Very child like. Others would intentionally start a conversation and, when asked a question, would say, "Hold that thought. I'll tell you later." and then disappear. I guess their thought is, "knowledge is power," and now they know something I don't. I wasn't impressed. Some AYAers were down right rude. Again, Mark and Kelly were the most impressive in what could have been an uncomfortable situation based on past history. Time to go to work. Oh, yea, Bill and Carol Scott. I got to watch them as they annualed a plane in a hangar at the airport. I must say, they did an very thorough and complete annual on that plane. On a new plane, new to me, I usually break down the depth of the annual over the first couple annuals. I cover the most critical stuff first and the not so critical stuff later. For example, the glareshield doesn't come off. I crawl under the panel and check for interference with cables, wires etc. I even oil the chains from below. Now I know why they charge $2500 for an annual.

Experimented with the right front baffle and have the CHT's all reading the same (within 1 degree) at lower altitudes. Thats at best power level flight at 4500DA with OAT 86 deg F. All read around 354degF. On climbout was seeing a spread on CHTs 380 to 400 with OAT at 100degF at about 90kts 1250fpm. All this with no air exit at nose strut.... One oddity I'm not used to seing is that at some richer settings the CHT's are higher and more uneven than when leaned out. Any ideas? Still working on the speed. Reinstalled the old cowl in order to center the engine. No small feat;) Engine was still down about 3/4" and to the right about 1". Just like it was before the Jaguar cowling install Found the upper left shock mount bolt had NO threads showing thru the nut....Tightened to spec'ed torque and checked other 3. This brought the engine into center of old cowl Next project is to center Jag cowl raising it about 3/4" and moving to left about 1" It now flies straight and level hands free with neutral trim tabs and equal flaps whereas before it tended to turn to the right.
