We do have an obligation to take good care of ourselves, but we cannot choose our medical condition. If we are in good enough health to drive two ton vehicles 80 mph just inches away from similar and/or larger vehicles being driven by inadequately trained inexperienced individuals talking on cell phones, we should be good to go flying too.

Two of the three RVs from Meadow Lake then went to La Junta (KLHX) for $2.80 100LL. it is $3.70 to 3.90 at 00V. Today I flew to KLHX to make a produce run at Van Hooks then fill up on that 100LL. Then on to Pueblo (KPUB) for two VOR approaches. Pueblo controllers are very nice and make practice approaches a pleasure. This instrument training is adding many new skills that will make flying better when I can get up or down through a benign cloud layer instead of cancelling trips like I do now. Another wonderful day of flying with 100 mile visibility. Some light turbulence from the winds over the mountains but that will end by Tuesday.

I understand Vans sells them as well. I have one mounted in my -4 to hold a 296. I have uploaded a photo so you can see. Unfortunately the picture does not show how far it sinks the unit into the panel but if I had to estimate it is about 60%. One nice thing about these is that you can remove the GPS if you want to take home, update or service the unit vs. a custom mount behind the panel that will make it more difficult to remove. http://www.make-it.com/RV/Panel.jpg Robin RV-4 200 hours -----Original Message----- From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com] On Behalf Of Ron Patterson Subject: RV-List: Panel Mounted GPS --> RV-List message posted by: Ron Patterson I was planning to mount my Garmin 396 as my primary nav instrument just under the Dynon D10A.

Sometimes it takes more. As for balancing the nosegear, the pivot point is only a few inches aft of the front of the wheel pant, and to balance the nosewheel would take significant weight on that short moment to counteract the longer and heavier moment of the tire. Just an observation. I don't think balancing the nosegear/pant is the answer ...... the answer lies in the correct assembly of belleville washers and the tightness of the nut.

I have a TD and never had to bother with balancing a nosegear. I think there are two different forces at work on the nose and main gear causing them to shimmy. The main gear are more prone to side-to-side shimmy because of the geometry of the gear leg, vs. the nosegear. I do stand by the value of balancing the main gear pants, but as with anything else in this business, YMMV. For those who don't know about balancing wheel pants, a picture or two is worth a thousand words. http://home.mindspring.com/~rv6/RV6site/wheel%20pants.htm Jeff Point ________________________________ Message 16 ____________________________________ Time: 03:12:42 PM PST US From: "Alex Peterson" Subject: RE: RV-List: Re: Wheel pant balancing fiasco --> RV-List message posted by: "Alex Peterson" > Before all I really had was minor to moderate shimmy of the nosegear. > I could count on it at around 18 knots while taxiing. > > I balanced on a rod about the landing gear axis.

I've watched nosegears on RV's do an interesting pitching "shimmy". I don't know why. Back and forth (castering) shimmy is a whole different thing, which should be eliminated by increasing the break out force or playing with air pressure. Keep in mind that it is important to keep the nosegear tire inflated as much as possible, because they are notorious for chewing up innertubes on the sidewall. I make sure that the edge of the tread is a little off the floor, maybe 35 psi? I've never had nosewheel shimmy, but I do have a main gear fore/aft oscillation that an outside observer noted. In my case, I never had it with the old crappy tires that came with the kit, but when I switched to Michelin I had this very noticable fore/aft movement at 23 knots. I balanced the main gear fairings also by putting lead in them, as regardless of whether or not it eliminates "shimmy", it should reduce pitching forces on the fairings when taxiing.

From: "Greg Young" --> RV-List message posted by: "Greg Young" Bill, I've had a love/hate relationship with AnywhereMap for the 5 years I've flown with it. One of the reasons I got it was that I carried an Ipaq for business and that made it a tremendous bang for the buck to get a color moving map - at that time, 2001. If you don't already have a PDA, today's value comparison is a lot different. You've got lots of very good choices. I spent a lot of time at the 2004 SnF looking for an alternative since my Ipaq was dying. I elected to upgrade my Ipaq to a 4705 and stay with AWM because it was a dirt cheap choice (aside from the Ipaq which I need anyway.) It cost $20 to get a new connector and yoke mount plate and a little time to solder 6 tiny wires. The features that keep me with them were: the larger much better display of the HP4705, the AWM database contains private airports which the Jepp based products do not and AWM displays TFRs and provides hourly updates that can be downloaded. It's got all the spiffy features of most moving maps but those couple were distinctive and a plus for me. But that was 2004. Now the downside and why I will very probably replace it in the next couple months. No particular order other than the first one. 1) The database, in particular Class B&C boundaries, is WRONG. Well not everything but there are known errors that could get you busted. When Houston IAH added a new runway the Class B was changed to add an East-West corridor with a lowered floor. AWM did not incorporate the change until about 6 months after it was effective. When I complained, I was told that their database could not handle the complexity and besides, AnywhereMap SHOULD NOT BE USED FOR NAVIGATION! Huh??? About a year ago, I noticed a difference in the corridor boundary between AWM and the Jepp database in my GX-60. Apparently the FAA made an in-stream correction to the boundary (moved it 2-3 miles north.) Jepp got it, AWM did not. When I told AWM about it they said they used gummint data and couldn't change it and besides, AnywhereMap SHOULD NOT BE USED FOR NAVIGATION! A few weeks ago I screwed up and was looking at AWM on my yoke (instead of the GX in the panel) during my climb out. The controller caught me clipping the floor but was cool and just gave me the altimeter setting. I thanked him as I pushed over. I sent another note to ControlVision about it but got no reply. I have heard from other AWM users that other SUA errors exist including wrong altitudes. It is also rumored that CV purges their forums of negative comments. 2) The Ipaq connector and AWM's mounting method is a weak point in the system. The serial connector on my old Ipaq failed (so it wouldn't charge in my desktop cradle) in part because of the AWM connector/yoke mount plate stressing it. The 4705 version is much better but it's still a weak point. 3) It is not realistic to operate off the internal battery. I started with a CF card GPS and battery life was extremely short. The CF GPS was also poor at capturing satellites and I eventually switched to the combined GPS35, cig lighter, serial cable bundle. Performance is good but there is no battery only option. 4) You can strangle yourself with cables. The cable I've got now has one cable from the yoke to the cig lighter and one from there to the mouse on the glareshield. I just slide the Ipaq into the yoke plate when I get in. The connections have evolved and it's way better than what I started with. A battery Bluetooth GPS might be even cleaner but I've heard of some connection reliability issues with Bluetooth. 5) The Ipaq is susceptible to cockpit heat. I've had it overheat when I left it on the yoke during lunch - with the canopy open, the yoke shaded and only ~95deg. Once I had to do a hardware reset to get it back. Other times the display started functioning when I got it cooled down. The Ipaq was designed for office use so I suspect the dedicated units are more tolerant of heat. 6) I had a bad experience with their PocketPlates product. I bought it when it first came out and fooled with it until my subscription ran out. It never really worked. They changed formats multiple times, never delivered geosync'd plates, you couldn't run it with AWM and their update process was fatally flawed. I basically bought into vaporware - my fault, I'm a software developer and should have known better. 7) I'm not real comfortable with the quality of their software development. Too many quirks, flaws, architecture issues and rookie mistakes to believe they're pros. Like the latest major release, 1.7, that corrupted all your user waypoints when you upgraded. Oops... Also, on 300nm legs or more I can see a significant difference in the great circle route plot between my GX-60 and AWM (several miles apart) - which would you bet is right? 8) Portability is a problem with my setup. Now that I've got everything routed and secured I can't really move it to another plane. When I was doing my IFR training in a rental I carried it but never used it. On the long cross-country after things settled down my instructor pulled his Garmin from its bag, turned it on and threw it on the glareshield. It would have taken me 10 minutes to sort mine out so I just forgot about it. 9) For auto use, I'd have to buy a street mapping application and then worry about how to mount it and get the GPS antenna positioned - i.e. see all the above. With all that said, I've finally had enough. I blown a lot of money and way too much time on Control Vision and AWM to still be left with a kludgey system. It was great in 2001 but it's time has passed. Now that I've seen the Garmin 396, I'm trying hard (well, maybe not that hard) to talk myself out of buying one. Then I can get a phone with a PDA and I'll have one less thing to carry around. If you can do without the XM there are a lot of good deals out there, including NOS 295's. Good hunting.

He aero-braked for a long way, probably until the elevator didn't have enough authority to hold the nose off. Once the nosewheel was on the ground, the pilot maintained full up elevator. In other words, the pilot was doing everything "right". Despite that, as soon as the nosewheel touched, the nose gear fairing (and presumably the everything else up there) began a noticable shimmy in the up and down (or fore and aft) plane. The amplitude wasn't large, but there was definitely a shimmy. It ended about the time he was at walking speed. My experience with the runway at Lebanon is that it is in great shape - so I don't think the runway surface was the problem. I wonder if this fore/aft shimmy has any relationship with the nose gear failures that have occurred with more than a few -A models...

Well not Somewhere back in the archives is probably my comments on AWM which I tried in good faith. Suffice it to say, I agree with Greg. I did not find it to be reliable or accurate.

They just moved into a new 3500 Sq.Ft. facility in Farmington, MN, and they want to see how many people it can hold. (My personal bet is no more than 1650 ;) ) There will be a Chelton Factory Representative attending and giving a detailed overview of the Chelton EFIS system, along with Q&A for users or prospective users. (I believe there may also be some promos ending after the open house...so you may want to jump on them) TruTrak Flight systems General Manager Andrew Barker is also attending to discuss TruTrak autopilots and new/upcoming items. They'll also be having *FREE* food, which is always a plus. For the full details, go to: http://www.steinair.com The open house is located at their new facility, which is located at: 21170 Eaton Ave, Suite C Farmington, MN 55024 Located just off highway 50 and Pilot Knob Rd about 3 minutes from Lakeville Airport (LVN). The open house will run from 10:00am - 5:00pm with the free brats/dogs around noon and other refreshments all day. Those wishing to fly into LVN may do so, and free transportation will be provided from the airport to their facility. -- Tim Olson -- RV-10 #40170 (I plan to be there) DO NOT ARCHIVE ________________________________ Message 23 ____________________________________ Time: 07:56:04 PM PST US From: "John D. Heath" Subject: Re: RV-List: Re: Wheel pant balancing fiasco --> RV-List message posted by: "John D. Heath" My two Cents worth Nose wheel shimmy is sometimes by caused by opposing steering geometry. With the aircraft loaded as it would be when shimmying, on a level parking ramp the nose wheel must have zero camber or it will try to turn into the camber. At a point the caster will overcome it and vigorously correct even to the point of over shooting. The cycle will start all over again and the shimmy has begun. Camber must be zero as measured at the steering axis and the wheel. The caster must not be tipped aft at the top (positive) or it will over shoot center steer and rake will oppose it. Rake is the distance between the steering axis and the center of the wheel. Caster is the fore and aft angle of the steering axis from plum. Good things are zero camber, zero caster, slight negative caster is best (steering axis tipped forward), 22 lbs of preload, and 28 psi air presure in the tire. Bad things are no preload on the steering axis, so do what you got to do to get it, Positive caster (bent or settled gear, loose in the engine mount and etc), Other than zero camber (bent or settled gear, improperly aligned or loose in the engine mount, wheel fork axel holes and steering axis not 90* to each other and etc). look for combinations. I don't think balancing the nose wheel pant matters one way or the other but main wheel pants balance is a must. Hope some of this helps John D.

Steering preload on a properly mounted gear leg will eliminate it. I don't know the nature of the failures in question but enough mass is involved to propigate a fatigue crack that could lead to instantanious failure in the leg or the mount if not properly maintained. > > > ________________________________ Message 24 ____________________________________ Time: 10:43:39 PM PST US From: HCRV6@aol.com Subject: RV-List: Harry gives up on dial up.
