They are both "Type IX" - Mil-C-17 cables, with a temperature range of -55oC to +200oC. #7) RG-400 weighs .050 lb/ft, RG-393 weighs 0.175 lb/ft.. #8) RG-393 is really neat of you want the RADALT to work properly. ----Original Message Follows---- From: "lucky macy" <luckymacy@hotmail.com> vansairforce@yahoogroups.com Subject: [rv8list] RV-393 vs RG-400 vs RG-58 Speaking of not using RG-58, here's what a professional EMI engineer told me at work. We were discussing a RADALT issue we have on a aircraft. "When in doubt, use RG-393 or better for RADALT applications. Also use a swept elbow if you have to turn a corner. Do not use mitered elbows as the pulse will get distorted from a non-linear group delay at the corner. The advantage of RG-400 over RG-58 is double shielding with better optical coverage and better quality Teflon dielectric centers. RG-393 is 0.23 dB/ft at 4300 MHz (rated at about 50 W CW@ 4300). RG-400 is twice the loss. I'd also use RG-393 for GPS but RG-400 will still work." lucky ----Original Message Follows---- From: rickrv6@aol.com Subject: Re: [rv8list] Re: light speed ignition questions Mark, Take a look at this article written by Bob Nuckolls: http://www.aeroelectric.com/articles/RG58/RG58.html He provides an even different alternative to RG cable.

    --> RV-List message posted by: N13eer@aol.com I don't have an autopilot yet but I am leaning towards the TruTrack over the EZ-pilot based on the installation. TruTrack supplies all the brackets and fittings needed along with installation drawings. With the EZ-pilot you have to come up with your own mounts and installation. I figure it is a weekend of down time rather than two. From what I have read both systems perform great. Alan Kritzman Cedar Rapids, IA RV-8 130 hour without an autopilot

    Subject: Re: Dynon OAT Probe
    From: "Lockamy, Jack L" <jack.lockamy@navy.mil>
    --> RV-List message posted by: "Lockamy, Jack L" <jack.lockamy@navy.mil> Larry, The Dynon OAT probe cable I received was only 8 FT long. Thus it eliminated any chance of running the probe under either wing in my case (remote mag compass module located in aft fuse on F-707 bulkhead). Based on replies I received when I first posted this thread, and a bit of head scratching on my part, last night I installed the probe under the H/S.... right side, approx 8" back from the leading edge and 3" down. Again, I have not flown yet so I can't say whether or not this location will be suitable, however the probe is shaded from direct sun-light, easily accessible, and hopefully will not be affected by exhaust heat. Seemed like the best location for my particular setup.... As for the other part of your post, I purchased the probe so I would have access to ALL the features in the Dynon EFIS. As you know, without the Dynon OAT probe, you will be limited to displaying IAS only. True airspeed and density altitude will now be available to me at a glance. I agree TAS is not a real important number when you have ground speed from a GPS, but having the Dynon calculate density altitude is data I'm sure I will find extremely useful. FWIW...I'm also using the Grand Rapids EIS-4000 engine monitor with their OAT probe that will be mounted under the right wing. No, the two are not compatible.... I asked! I installed this option not knowing if/when Dynon would be releasing their probe. Now I will be able to compare the two. I believe the Dynon Configuration software will allow adjustments to their OAT probe readings. Modern technology is a WONDERFUL thing! :-) Jack Lockamy RV-7A N174JL reserved Full IFR panel completed starting canopy

You can also monitor the headwind/tailwind component during your flight. A GPS and the TAS on a MicroEncoder allows this, also. Jim Ayers

    Subject: Re: Autopilot Itch
    --> RV-List message posted by: "Doug Rozendaal" <dougr@petroblend.com> For me it comes down to this. I have a Navaid, and I plan to upgrade to the Trutrak because of the Turn Coordinator presentation. The performance of the Navaid is not perfect, but perfectly adequate. I am certain the Trio and Trutrak are nearly perfect. I looked at the Trio, but the Turn Coordinator presentation on the New Trutrak and the fact that Jim Younkin is behind it, makes it an easy choice for me. It would be VERY Difficult to fly partial panel in any turbulence at all with the Navaid. Having said that, if the Navaid, or any autopilot, was working, I would turn it on and fly the airplane with the GPS or the turn knob on the Navaid. An added benefit of the Trutrak is the ability to fly a heading, the Navaid will wander if left unattended and not coupled to the GPS, but that feature is not worth the upgrade price, the Turn Coordinator presentation is. If the Dynon quit, and I was in turbulence, I would probably pay $10,000 for a better backup. Tailwinds, Doug Rozendaal

    Subject: Blue Mountain EFIS
    --> RV-List message posted by: "Terry Watson" <terry@tcwatson.com> I know of three that are flying in RV's, one in an RV-9 and two in RV-8's. There are many flying in other aircraft. Check their website (http://www.bluemountainavionics.com) for lots more detail. There was a hint of a new model to be announced at Sun N' Fun. I am installing the BMA EFIS/one in my RV-8A and continue to be pleased with my decision 18 months ago to go with them. They continue to improve what they have and add to the capabilities. They now have an integral 2-axis autopilot capable of flying your flight plan, HITS (highway in the sky) capability, something almost like synthetic vision where the terrain is shown color coded on the moving map (I think the new Garmin 296 has this) and on the artificial horizon of the attitude indicator. They also have put together a package of engine sensors to work with Lycomming and Van's aircraft, and you can now buy the whole thing from Van's. The latest upgrade for me was a switch from a DVD drive to hold the charts and terrain info and update the system software to a little Compact Flash card just like the one in my Cannon digital camera. Along with this change came the ability to download engine sensor, air data, and GPS position recorded every 5 seconds and analyze it with a PC program.

    --> RV-List message posted by: "Greg Young" <gyoung@cs-sol.com> Pretty simple - a carpenter's square would be flush against both the root/open side and the top. The "flat-top" of the tip is an straight extension of the upper wing surface, in fact you fit it by laying a straight edge across the wing and tip. If it's not that and came from Van's it's a sheared tip.

    Subject: Re: Most efficient climb
    --> RV-List message posted by: "LarryRobertHelming" <lhelming@sigecom.net> On this question of what is the best climb rate, it should also be a concern that we are flying in a system where others are flying other, and opposite, headings according to the hemispheric rule. If we climb more slowly, we are spending more time is the other pilot's air space regarding altitude. Accordingly, it seems we should not make this necessarily the most efficient climb rate, but one that regards safety also. Something to consider as it applies to long slow descents too.

My flaky memory is telling me that he mentioned something around 120 mph instead of the expected ~90 mph. The idea was that the low aspect ratio wing causes (induced?) drag to go up more when you get down in the 90 mph range. He pointed out that if you climb at calculated 'best climb' using traditional techniques (1.? x stall), then try the same throttle setting but climb at ~120 mph, you will see the same *rate* of climb but will cover a lot more territory on the way to cruise altitude. I don't remember if he mentioned whether fp or c/s made a difference in these numbers. I can say that I've tried it on 2 different fp -4's & my neighbor has tried it in his fp -8, and the effect was easy to see. Kevin, can you give a sanity check on this? Charlie

    Subject: Re: Most efficient climb
    --> RV-List message posted by: Denis Walsh <denis.walsh@comcast.net> 120 MPH IAS is a good climb speed for enroute. In addition to the reasons cited by Charlie, I would add that this speed also gives the best visibility during the climb. A slower speed gives you a really big blind spot under the nose, which requires more clearing turns which really slows down the rate of climb, not to mention ground speed to destination direction.

    Subject: Fw: Off-line reply to your - Finish Drill / Deburr Pre-punched
    holes? --> RV-List message posted by: "Rob W M Shipley" <rob@robsglass.com> Everyone please note that Scott McDaniels has gone to the trouble to give us an unofficial Van's view of this topic and afford him a courteous reception - unless you wish to ensure that he won't contribute again. I received this directly from Scott today. Subject: Off-line reply to your - Finish Drill / Deburr Pre-punched holes? Hi Rob, I am not currently a subscriber on the list but I do cruise the archives on occasion to see what the latest hot topic is. I saw yours and thought I would take a moment to reply, but I didn't even have time to read the other responses so sorry if this is some what redundant. I also am not sure how much of the below is yours or if some is pasted in but I will answer some of the questions to hopefully finally put to bed some of the confusion and miss information about what has been done in the past at Van's in regards to assembling without drilling. I work in the proto shop at Vans and have been there about 8 years, so I have been involved in the evolution to the current level of P.P. holes in all of the kits. --> RV-List message posted by: "Rob W M Shipley" <rob@robsglass.com> >Too many experts and not enough pragmatism. >Tedd McHenry kindly posted the links for the mil rivet specs. There's a problem here not addressed by those who feel Van's recommendations are akin to a quick spritz with holy water. Follow directions and you will NOT meet these specs. Regardless of what the specs are, if you build to the recommendations in the manual then you are building to the same standard as was used to build test items that were static loaded to verify that the structures met the loads that they were designed too. If you feel better starting with a hole size that is a few thousandths smaller then go for it. I don't think any one at Van's has a problem with that as long as you are using dimple dies that have a pilot that is not stretching the holes when you insert it (the pilot is a clearance fit to the hole). >Charlie England's post echoes my own experiences. Match drill, deburr and dimple and your hole will be oversize on the thinner skins by as much as twice the allowed tolerance. See my response above... all the testing was done with parts constructed this way. If you do not feel good about it the use a smaller hole. >You can't buy #41 dimple dies and everyone has done it this way for years so it works. If you match drill with a #41 instead of a #40 it works better, i.e. the hole is tighter, you need less swell from the rivet and the recommended rivet size is more likely to work. This has nothing to do with recommended rivet size. They are spec.ed by what we used that did work when building the proto parts. Some times sizes are called out wrong (we're not perfect) but it is surely not because the hole is a few thousandths bigger than a Mil. spec calls for. > I'm sure the theoreticians out there won't like this suggestions much, however no one at EAA, AOPA and the guys at Vans considered it a bad idea, when I discussed it with them. And I have no problem with it either unless you are using dimple dies with a pilot that doesn't fit the hole. I do have a problem with Not final sizing the hole from what is punched, but just slamming dimple dies into them. >Paul Parashak is concerned about "one of the surest ways to accelerate metal failures is to introduce a flaw. These miniscule cracks and stress areas that are left in are prime areas for crack propagation." I cannot believe that he has ever examined the holes which the average builder drills and deburrs. Look at one with a magnifying glass. They are ugly to varying degrees but definitely ugly. Cy Galley has a good grasp of the reality of drilling and deburring. "If you are getting so anal about drilling, I would propose that you use a chucking reamer instead of a drill. At least that way you will get a round smooth hole. You don't get smooth or round with a drill bit." If irregularities around the hole are significant, many riveted aluminium monocoque planes would not have remained flying for as long, (or longer), than many of us have been alive . How many of those airplanes are 100% flush riveted on the exterior? Not many. When you dimple, you are stretching the material. If you had to force the dimple pilot into the hole before dimpling you stretched it even more. Now if all of this was done on holes that had never been up sized, you have a strong potential for cracking. The punching process leaves a hole edge condition that is the same as a sheared edge on a skin at best. Some times it is worse because of a punch tool that is getting slightly dull or has a little more clearance that when it was new. It is for this reason that it is recommended in the manual that the holes be final sized. True, it may not a perfect hole but that is ok. That is what made riveted construction of aircraft so desirable. >He also makes the very pertinent observation that presumably all the lightening holes are punched by Van's. I haven't heard any suggestions from Van's or our list experts regarding the necessity of enlarging these to remove the work hardened edge and the attendant stress risers. Not true! Builders are told to deburr the edges of all parts (this would include lightening holes). In our shop we use a small scotch bright wheel in a die grinder to deburr/smooth all lightening holes and we assume builders are doing similar. >Vans has not totally dismissed the idea of dimpling the punched hole without match drilling. Charlie England's discussion with Van "I asked Van, his own self, face to face, in person, at OSH last summer when they were going to go ahead &punch the holes 'full size' &save us all some build time. His answer (his *only* answer) was that there was enough variation in drilling patterns that they preferred to continue the match drilling thing for now." I think you are reading more into this than you should. That in no way means that we would punch them full size if we were confident that the would all line up properly. >I also had asked Van's about the rumour I'd heard that they had experimented with this by building a wing or wings without drilling and was told it was true but too early to make any comments. I didn't think to ask them what plane they were for or if they would fly them. I'll ask Ken K. next time I see him. There was never an "Experiment". It was a time saving short cut only when building structures that we were using for static testing. It was mentioned in an RVator only to describe how well the pre punch design work was going and to describe how well the parts fit. It was never intended to present a process that should be used to assemble the kit. We have never done this on any structures that we intended to fly. The cracking issue is related to the life of the structure with thousands of load cycles. The structures we did this on only had to last through 1 or 2 load cycles. >Van is most certainly not reluctant to tackle issues he considers dangerous for example his stand on not using engines larger than the O 320 in a 9. He is also notoriously conservative and yet he has not made any attempt to take on this topic in a similar forthright fashion. This is surprising if, as our theorists believe, this is a serious problem in practice. I wonder why. >There are many discrepancies between our practice and theory - hole condition, size etc. and it would seem that little is known about dimpling and riveting punched holes in practice. I have read nothing about actual stress cracks seen in aircraft riveted together without match drilling Lets see... I have not seen a large campaign calling for an outsider evaluation of the wing engineering on any of the RV models, do builders acccept on blind faith that the wings are designed properly but they will not acccept it when the manual suggests that they final size all of the holes before dimpling? In my opinion, the absolute bottom line is this... No one at Van's, or probably anywhere else can tell you with absolute certainty that you will or will not have cracking problems on your RV 10 or 15 years from now. We have no experience or data to prove it one way or the other. This is something that would not likely happen right away. There are probably RV's now flying that were build without drilling. The owner/builders may even be preaching to everyone that "They haven't had any problems". That information of no value. Tell us after the airplane is 10 years old. I doubt very much that if Van's endorsed skipping the drilling, and 10 years from now a bunch of RV's started to have cracking problems, I doubt those owners would consider it much a consolation for Van's to say "Sorry, I guess we were wrong. From now on we recommend builders don't do that any more". So, If anyone is willing to experiment, and take a chance, to save maybe 20 hours of work ( a very small amount considering the total number of hours most builders expend) on the construction of there RV , then go for it. Just realize that no mater how many experts you talk to, or how many other builders have already done it, only time will tell wether you made the right decision. I hope at least some of this is of some value but I have to close with the standard disclaimer dribble... This is my own personal opinion and does not necessarily match the policy's or opinions of my employer. P.S. feel free to share this as you wish, as long as you promise to refrain from flaming me without a chance to respond since I'm not on the list :-)
