You'll love it! If you get a chance, stay at the H.H. Springs Hotel, the big resort hotel (not to be confused with the many smaller hotels). If you can't stay there, at least visit it with your bathing suit. It is unbelievable! Hot tubs of various temperatures, swimming pools, some of them are connected by hot streams, underwater lighting, and beautiful wooden walkways. The hotel is spectacular and its setting is on the secluded shores of Harrison Lake. Long walks on the beach and hikes in the surrounding mountains make it a world class location that very few people know about. It is 25 mins. drive north of Chilliwack, but fly over the lake before you park at the airport (CYCW). If you're staying a while at H.H.S. it might be cheaper to take a taxi there instead of renting a car and leaving it parked for a few days. You MUST also have pie at the Chilliwack airport restaurant overlooking the runway. The pie is made daily and is considered by many to be the best in B.C. You might think I have shares in H.H. Springs Resort, but unfortunately not, but I've been twice and would love to go back. As for CYCW, well, I send my private students to CYCW for pie on their long X-C. They have to do the trip twice if they don't bring back any pie! Chilliwack is a growing town on the Trans-Canada Highway and as a result should have a car rental agency, however not at the airport (5 min. drive south of town).The natives are friendly, so it shouldn't be a problem to get a ride into town from a fellow pilot at the restaurant. Chilliwack has very reasonable prices on most things, so I imagine you'll get a deal on the car. Hope some of this drivel is useful. Cheers, Chris Carpenter 8 - wings Do not Archive PS- On the way, circle the crater of Mnt.

Few if any more "front end" features than a steam gauge HSI. As for the features embedded in the system to talk with other equipment, I am not an avionics engineer, but it looks like you have some good equipment interface comments here from others. Airplanes are becoming too "feature rich" I fly with too many pilots who make flying more difficult, not simpler, by trying to use the "features" in all the magic they paid good money for. This is a serious problem in our industry. The FAA has just announced a rewrite of the Inst. Rating Practical Test Standards to address this, but the FAA is still concerned as are the airframe manufacturers. All the features that are available can add utility to an airplane, but the problem is, they add workload too. Many IFR pleasure pilots that I see are marginally current at best. For this crowd, they should be turning the toys off when they fly IFR, not looking for more "features" to fiddle with. You cannot install experience in the panel. The VFR folks have no need for most of the toys they have and spend time fiddling with them when they should be looking outside. Sorry folks, but I get to fly in lots of airplanes with lots of pilots and this is a widespread problem. I vote for a simple system that works well and has a fair price like the D-10.

When I redimpled it the right direction I heard a little ping as the metal went from flat to dimpled. This I believe was the sound of cracks forming circumferentially on the raised dimple. The cracks were only noticeable under a magnifying glass. It didn't take too much poking with a tool to get the dimple to fail completely. Van's said that redimpling is safe if no cracks form, and I noticed in the archive that others have encountered the same reasonable recommendation. However, in the case of the heavier gauge pieces, I recommend examining the metal closely and then just order a new part like I did.

Thanks, what a great bunch of people. Now the story. It all started on a tiny island 600nm SE of Florida. Grand Turk island (MBGT) for those that wish to find it on a map. One of the RV's was giving a ride to the local Dive Master when the LASAR ignition light started blinking. Subsequent ground checks proved that the right mag was dead. A quick phone call to Unison and new mags were on their way to KFPR in Florida. His wallet was also quite a bit lighter. Since RVers are safety oriented folks a two ship flight (safety in numbers) was dispatched on Saturday morning to retrieve the parts from KFPR. All went well and after refueling, getting the parts and a little breakfast we headed back over the turquoise waters to the islands. On climb-out somewhere around 3000' the engine in 99PZ started missing and generally running rough. Since we were not to far out I radioed the lead ship that two was headed back and we both made the turn and landed without incident. I pulled the cowl, checked the plugs, checked all the connections including plug wires and found nothing out of the ordinary. A 25 Square ground run went well so we re-cowled the plane and again headed for the islands. We made it a little further the second time. Running down the coast of Florida and after ICAO flight plans were opened 99PZ started missing again. I guess PZ was determined to stay over land. A quick check again proved it was the EI side and not fuel or carb ice. Turning off the mag would cause the engine to run real rough and pop and sputter. My wifes eyes were as big as oranges by this time. I turned off the EI and returned to KFPR again without any further incident. Lead decided to keep going with the parts to fix the original plane. We borrowed the local courtesy car and ran down to NAPA and bought 4 new plugs for the EI side. After installing the plugs I started the engine and now the EI side would not work at all. At least now it was a hard failure and not an intermittent one. After checking into a local hotel I found and internet access terminal with a bad keyboard and sent a plea out to the RV-List for help. After getting Jeff Rose's number I called him and discussed my problem. Jeff felt the culprit was the Hall effect sensor and suggested checking the resistance of the pickup. Another trip to NAPA and 20 bucks lighter I had their cheapest VOM in hand and checked the resistance of the sensor. It was good. I started checking all the connections again and found the red wire on the brain-box end of the sensor cable was not connected to anything. I pull out my cell phone and called Jeff and asked him what the red wire was. His reply was "Thats the Sense wire". I had found my problem, or so I hoped. I rummaged up a #22 butt splice (radio shack brand) and repaired the red wire. Another ground run and the EI side now worked. The next test was t see if it would work in flight. We strapped ourselves in and took off. All systems reported normal so we pointed the nose towards KCTY and points beyond and 9.5 hours of flying later (two fuel stops) we arrived back home in Denver without the EI ever missing a beat.

Many have requested lots of features, and they are all good ideas. I would like to suggest going the other direction - having a very simple and cheap alternative to todays (yesterdays?) gyros: A simple stand-alone digital DG. a simple stand-alone AI, a simple digital stand alone TC. All with the same user interface we are used to (on an LCD panel though), but much higher reliablity, lower price ($400 a peice? is that feasable?), while smaller behind the panel, much lighter - that is exactly what we could all use. If you are looking into something less "conservative", then why not go all-out radical, and try something completely new. how about a real time V-N diagram? I'll send you a drawing of what I have in mind seperately (can't send attachements to the list). My thoughts.

From: "Bartrim, Todd" --> RV-List message posted by: "Bartrim, Todd" There has been a few great suggestions already, but the GPS question brings up an opportunity. An interface with any of the existing products is likely the best (cheapest) solution, however if the plan is to have it's own internal GPS, then I'd like to suggest looking into the Russian GLONASS system. Use of both GPS & GLONASS with position calculated from averaging the signals or selecting the stronger signal(s) would provide greater accuracy and redundancy in case of system failure. I asked on the list about GLONASS a few years ago, but most of the replies that I received claimed that it was not a serviceable system due to system maintenance neglect, so I researched it a little further and found that on the contrary, the Ruskies had just put up 2 new birds to replace aging satts. They continue to have 24 satts in orbit just like the US GPS system. Unfortunately most of the info I found was written in Russian. Another one to consider, since any new product that you may be considering developing is likely several years away, would be the proposed European Galileao system due to become operational in 2008. This will be a commercial system (versus military), with 3 meter accuracy for free and 3mm accuracy for a fee (?? I know, I find this hard to believe too). This is likely more than you'd like to consider for your proposed instrument, but you asked and I'd love to see it. S.

My RV4 doesn't have stiffeners and I wouldn't put them on, here's why. Once I landed at Rochester to have breakfast at a restaurant called Karen's. Now, to get to this restaurant you have to taxi over a neatly mowed field. While I was taxing, my left wheel dropped into a gopher hole, The airplane made an immediate left turn, 180 degrees. I figure the only thing that saved my gear and motor mount, was the Whitman gear. If it had been stiff, I probley would have had to replace more than just the wheelpant. I realize that this could only happen to me, but for those with luck like mine, here's another way to look at gear stiffeners.

Van hired an FAA Designated Engineering Representative to supervise the static load testing. The static load tests were done to the FAR 23 aerobatic aircraft criteria, which require loading of 1.5 times the loads at the in-flight load factor limit. In other words the sand bags represented a load of 9g at the aerobatic gross weight. They did two load cases - one representing 9g at the stall, and the other representing 9g at the recommended VNE. The wing passed both cases - i.e. it did not fail. FAR 23 allows the manufacturer to use a new wing for each test case, as the wing may be damaged even though it does not fail, so it could fail the next test. Van used the same wing for both test cases. It is not really practical for a builder to do such a test for a number of reasons: It takes a lot of knowledge to be able to calculate the correct load distribution. I.e. how much weight, and how is it distributed on the wing spanwise and chordwise. You need more than 9 times the aircraft weight, as the tail produces a down force that the wing must also counter too. The wing will likely be weakened by such a severe test, so you would not want to use the wing that will go on your aircraft. You would need to build two sets of wings - one for the static test, and one to fly.

Clark" Subject: RE: RV-List: Help with tachometer pickup --> RV-List message posted by: "James E. Clark" Peter, What we did on our RV6 is to attach a short cable from the engine to the pickup. The pickup is mounted on a "shelf" that also holds the GPS antenna just under the cowl. Seems to work just fine. I think I got the cable from the "Aviation" department of some place like NAPA/AutoZone. Email me if there are additional questions. James p.s. Since you are "all electric", do you have an EFIS or electronic engine monitor along with Electronic Ignition? Many of these combinations allow for RPM to be determined from counting pulses on the EI. > -----Original Message----- > From: owner-rv-list-server@matronics.com > [mailto:owner-rv-list-server@matronics.com]On Behalf Of > PeterHunt1@aol.com > Sent: Friday, May 07, 2004 6:22 PM > To: aeroelectric-list@matronics.com; > rv-list-digest@matronics.com.pts.rule.name.description.----.------------ > ----------.-------------------------------------------------- > Subject: RV-List: Help with tachometer pickup > > > --> RV-List message posted by: PeterHunt1@aol.com > > After installing my SD20 alternator on the vacuum pad of my > 0-360-A1A, I find > there isn't sufficient clearance for Van's tachometer transducer to screw > onto the tachometer outlet on the back of my engine.
