Several articles were published by Light Plane Maintenance magazine beginning July 2000. I got a copy at Oshkosh, FAA Safety meeting, or somewhere and recently read it. Here is reference for back issues: http://www.lightplane-maintenance.com/pastissue.html In sort, when using autogas in our plane we should, for our own safety and our engine's, test each batch of fuel for water/alcohol, octane rating, and Reid vapor pressure. Supposedly the equipment needed for this testing is available from ACS at reasonable cost. In addition, each autogas purchase may have different brand additives and time-of-the-year/season related additives, different additives due to state, EPA, and local regulations/fuel laws. There is none of these differences in AVgas. Each batch of AVgas is identical regardless of where or time of year it is purchased. Vapor lock has been studied by the EAA. Here is 2001 reference: http://www.eaa.org/education/fuel/vaporlock.html In addition some airplane parts may be altered in size due to autogas additives. Here are other EAA references for anyone having further interest: http://www.eaa.org/education/fuel/materials.html http://www.eaa.org/education/fuel/oxygenated.html And if we are interested in considering a mix of AVgas with autogas, please read this article by EAA: http://www.eaa.org/education/fuel/fuel/mix.html And *finally* with a newly rebuilt engine, here is article by EAA on use of autogas: http://www.eaa.org/education/fuel/overhaul.html Indiana Larry, RV7 TipUp "SunSeeker" ----- Original Message ----- From: Subject: Re: AeroElectric-List: Capacitive fuel probe errors? > --> AeroElectric-List message posted by: Fiveonepw@aol.com > > In a message dated 04/27/2004 3:08:54 PM Central Standard Time, > terry@tcwatson.com writes: > There is a very recent discussion on the Blue Mountain Avionics discussion > list about capacitive probes and auto gas.

Recently, I flew Mark F's F-1 Rocket and found he had no drop at all on the electronic side of his ignition. I have always had a drop, but recently my airplane has not been running as smoothly as it did. I changed the plugs, that helped some. I put on new wires, that helped too, but I still have a 70 -80 rpm drop on both the mag and the Lightspeed. I read the book, got a timing light and checked the timing. The Mag is dead on at 25 deg BTDC. At 800 Rpm the Lightspeed is 35 deg.BTDC with the M.P. line connected and 15 deg with it unhooked. The way I read the manual (and they are not that great) is should be either 25 & 42 deg. BDTC (parallel valve IO-320) ( I did not build this airplane and the builder says it was always dead on,) My sense is this is a chronic deterioration, but I have not data to support that. Klaus says if it was ever right, it will always be right, or it wont work at all. Great theory, but I have been in the real world too long.... The airplane does not idle any better ont electronic than on the mag. It idles fine on "both." That is not right and something is amiss. I have checked out everything that I can think of outside of the unit? I have talked to the builder, talked to Klause twice, dug in the archives and I am at a loss. Anyone else have any ideas?

I worked with a couple of different problems with the LSSE and with one exception they were always the sensor that caused any problems. The one exception was that Klaus sent the wrong main box for the sensor installed. Anyways, check the sensors. The hall effects sensor has to be timedand they have been known to slip a little on occassion. If it is the flywheel sensor then you may want to check the gap between the pins in the flywheel and the pickups. Just a few ideas.

New plugs did seem to help temporarily, but that was probably due to the perception of it running better since the plugs were nice and new and clean. Replacing the seals is not a hard job and the gaskets won't cost you much, its worth some piece of mind to help narrow down your problem if you just go ahead and replace them. I rub the gaskets with titeseal and thoroughly clean the flanges with a scotchbrite pad. A while before that I had similar weirdness on runup and it turned out to be a new key switch purchased from AC$ that some conact cleaner took care of. Look beyond the ignition unit, its probably something else.

I appreciated your hosting of that contribution. And, it got me started on learning about web documents. - As the years have gone by, more people have created their own web sites and post their stuff directly on their own site - that is probably a significant reason for less contributions or archiving to the Bunny's List. - Plus, many will post to the list, but not take time to refine their problems and solutions and innovations for formal submission to a web site, driven by the "keep on building if you are ever going to finish" rule. - Matt's development of the Archives and Search engine also reduce the perceived need to collect stuff into one web site. However, there is a real jumble of RV-8, RV-6 slider, & RV-6 tip-up (and later models) that you have to wade through to get what is really relevant to one's own plane and personally desired outcome. - I think possibly the greatest impediment to "web site contributions" (whether to one's own site or someone else's like the Bunny's Guide) is simply the lack of knowledge and software and experience of how to format text and photos and sketches for posting. Just being able to write a Word document or e-mail isn't enough - someone has to do the detail work. A lot of people on the lists helped me learn & sort out some of the different software for displaying things as either .dwg or .pdf (PDF Factory is a great tool to format spreadsheets - electrical info - & CAD files for people who don't have CAD software or, mainly don't have the time and help to learn it well enough to use adequately). IRFAN is free and has all the features one needs to size photos and scanned stuff - great to replace the cheap, inadequate .jpg pgm that ships with Windows and frustrates the user. - In the end, though, I still feel, like you, that there should be a "consolidated" thing like the Bunny's Guide. Yesterday, I searched the RV-list archives almost all day and copied about 30 e-mails on RV-6 tip-up canopy and instrument panel (removable) info. Today, I start a split screen operation to create a substitute for the Van's Manual (like I did for each part of the empennage) - document on one side, screen to show an archived e-mail in other, then cut and paste/edit out of e-mail and close it and bring up the next. - It will incorporate my choices for canopy removal actuator system (maintenance only, not in flt jett), canopy side skin overlap below longerons, avoiding snags in front when raise, instrument panel (avoid interference with other structure in front of it/"behind" deeper instrument & radios, removable, notches and come up with a cad drawing), water/rain protection above radio stack, rain sealing in front, guide block for aligning of canopy when lowering into position, positioning of gas struts with inst panel on to avoid interference, etc. I'll send my documents & photos to you for the Bunny's Guide and post to my own site, also. Thanks, Frank, for you help and encouragement over the years.

My battery box is not exactly a box, but a flat piece of .125" with some angle around the edges of the batteries to keep them from moving forward and back or side to side. My fallback is the standard Van's method of using a U channel with a pair of long bolts, but I'm curious if there are better ways. The batteries will be behind my baggage compartment, and in the event of an off field landing, I don't want them flying forward.

My understanding comes from reviewing the product capability matrix (http://www.trutrakflightsystems.com/ttfsproducts.html) and from a short discussion with the TruTrak folks although I may not have asked the right questions. Isn't it the Nav Modes feature that allows a LOC or ILS approach? I've been thinking about a DFC 200 (or maybe 250) but would really like to have vertical GPS guidance ala the IIVSG. My phone call implied that this would probably be added to the DFC series in the future. If the IIVSG can really do an ILS approach, what does the "Nav Modes" on the DFC series feature provide? Since they both use the same servos I've ordered them for my RV-10 but held off on the actual autopilot.

It does all you asked about and more. It works as advertised and I love it. I am just about finished with my recertification of my instrument ticket (after 15 years) in my recently completed RV6A. Here is a sequence of use using GPS navigation and an ILS approach. On the ground, set cruising altitude in autopilot (AP) After takeoff, push a button on my Infinity stick to engage Control Wheel Steering (CWS). The AP will keep flying in the current configuration i.e. rate of climb and heading. Use CWS mode to select headings given by IFR Controllers. (select the track needed to fly the appropriate heading) At attitude, AP levels off. Trim. When established on the GPS Flight Path, engage AP GPSS mode. AP will fly the GPS flight plan, select altitudes as necessary. When nearing the ILS, select AP LOC NAV mode and enter inbound course. Select the ILS intercept angle on the AP. The AP will intercept the inbound course and altitude will be coupled with the glide slope keeping you centered in both axis. At DA, push the Vertical Speed Up button to select the rate of climb for missed approach and the AP will automatically switch to BC mode and track the Back Course. For GPS Approaches, its even easier. Whatever is in the GPS flight plan will be flown by the AP. Just select the altitudes you want on the different legs. The user manual can be found in the documents section of the TruTrak website.

They come with a 5 year warranty. They have to be ordered through Mark Claprood or Jeff Taylor (two of the Bose reps.) during an aviation trade show or a big fly-in. Bose requires that the set of 4 be paid by one person with a credit card. The next opportunity to get this deal is a trade show from May 18-20. You would need to confirm these dates with one of the Bose guys. Oshkosh in August would also work. I made my order during Sun & Fun two weeks ago. I've filled my order of 5 already. You would need to contact Mark Claprood at 508-766-4655/508-904-4659 or Jeff Taylor at 508-766-1083/800-766-8452. They only ship 4 of the five initially. They ship the 5th one (the "free" one) 30 days later to give the 4 buyers a return time period. You can request to shorten the 30 days if all the buyers are sure they aren't returning their headsets. I highly recommend the portable type with 2AA batteries. The hardwired type still has a volume control just like the portable type so you really aren't saving much awkward weight plus you can use the battery kind in different airplanes. My RV-4 is incredibly loud inside and the Bose is great. I don't work for Bose. This E-mail is FYI.

If one buys gas from a high volume station, it's a good bet you'll never see water in your gas. Let's face it. If a gas station starts selling gas with water in it, they're in big trouble. The worst time for problems with vapor pressure is when the temps outside start warming up from the winter months. Just before the gas companies start selling summer blends, one can run into vapor locking at fast turn arounds a bit easier. Alcohol is another matter. In some larger cities, alcohol is used in the gas. I'd say California would be a good candidate for this mix. I've tested fuel in my area and have never had alcohol in the gas. I limit my gas purchases to BP, Marathon, and Shell. If memory serves me, it's the gas sold under the chevron brands that may most likely have alcohol in it. Don't quote me on that, though. Anyway, it takes very little time to test a batch of fuel, if one wants to do that with each fillup. The savings is worth the effort. > In addition, each autogas purchase may have different brand additives and > time-of-the-year/season related additives, different additives due to state, > EPA, and local regulations/fuel laws.

Don't forget the cost that one pays for that warm fuzzy feeling! Around here, even at the elevated auto gas prices, avgas is about $1 higher per gallon. I've been using auto gas since 1986 and have had no failures due to the gas. For that matter, none of my fuel injected auto engines have failed either! In my old Skyhawk, I do remember a time when the float sank in the carby; but, so did the club plane's carby float the same week! Mine used auto gas. They used 100LL. > Vapor lock has been studied by the EAA. Here is 2001 reference: > http://www.eaa.org/education/fuel/vaporlock.html I don't fly above 10,000 feet. Most of my flights are no higher than 3500'. The only time I experience vapor locking is when I do a quick turnaround. When I was taking up a lot of Young Eagles, I'd just make sure I had some 100LL mixed in with the auto gas. Half and half is more than enough. Actually, I think 25% 100LL may be almost enough. If you're flying with a fuel injected engine, forget it. Those things do well to not vapor lock on 100LL! I honestly believe one can fly above 10K', if one blends in a little 100LL. I've not tested that theory, yet. > In addition some airplane parts may be altered in size due to autogas > additives. Here are other EAA references for anyone having further > interest: > http://www.eaa.org/education/fuel/materials.html > http://www.eaa.org/education/fuel/oxygenated.html I've not seen any of that in my airplanes. I've flown a 1965 C172 500+ hours, a 1977 Grumman-American Cheetah 900+ hours, and the RV-6A 300+ hours with it. I have done this over a period that started in 1986. > And if we are interested in considering a mix of AVgas with autogas, please > read this article by EAA: > http://www.eaa.org/education/fuel/fuel/mix.html The two will mix just fine. I usually add some 100LL to my airplane's diet on cross country trips where I can't be sure of the auto gas. I can always tell. The engine runs rough at start up when I add the 100LL. > And *finally* with a newly rebuilt engine, here is article by EAA on use of > autogas: > http://www.eaa.org/education/fuel/overhaul.html Yes, be sure to use 100LL during the break in period. That adds a nice coating of lead to the top end parts during the break in. After that, it doesn't take much 100LL to maintain that coating. I'm not sure how the capacitance vs regular float type senders differ. I do know that I don't put much faith in either. I check my fuel before I takeoff and know about what my airplane uses per hour. If my gauges show empty, I'm in trouble. That's how I set them up. If one is worried about additives in the gas one buys, one can call the manufacture, or maybe even the distributor, to find out what additives are used. Some are just fine. Some are not. Alcohol is a not. I've not ready the listed articles, lately, and can't be sure; but, I think MTBE may be one that's added often and is just fine in our engines. Read the articles, to be sure. I just hate to hear anyone downplay auto gas usage, as you can tell. Maybe Larry in Indiana really didn't mean to do that and was just giving some warnings; but, I've had folks tell me I'm going to crash and burn because of my auto gas usage. If the FAA says it's OK to use and are testing unleaded fuels that may very well become what we use in aircraft regularly, I think I can use auto gas with some confidence that I'll survive it. I think my flying regularly with it since 1986 should prove out my point. 'Nough said.

Of course you have to cut them to get them off, unless you find some of the removable kind. I think they are plenty strong enough, but if you are concerned, use two (or more). Since they are plastic, you don't have to worry about them shorting the terminals out.

My battery box is not exactly a box, but a flat piece of .125" with some angle around the edges of the batteries to keep them from moving forward and back or side to side. My fallback is the standard Van's method of using a U channel with a pair of long bolts, but I'm curious if there are better ways. The batteries will be behind my baggage compartment, and in the event of an off field landing, I don't want them flying forward.

As a flight instructor I have the opportunity to do side-by-side testing of various headsets with my students, who have a variety of headsets. I only tested ANR sets Immediate switching of headsets back and forth under same flight conditions (RPM, Airspeed, Aircraft are constants). I use Telex Stratus 50D. Compared with: David Clark ANR, Lightspeed 3g (and lesser models of lightspeed), Bose X (latest), Sennheizer ANR. Conclusions: David Clark are toughest but also have the least ANR noise reduction, but best Passive noise reduction and possibly the best warranty (I'm sure up for debate). Lightspeed have very good noise reduction, but are not as toughly built as the others, best ANR for the buck but passive noise reduction is poor (due to thin ear seals I believe). Bose is most stylish, lightest, least bulky and ANR is very good, like Lightspeed's ANR, but with better Passive noise reduction. Very noticeably not as good as the ANR in Telex 50D. Telex 50D very noticeably better ANR than all tested with only the David Clark having better Passive noise reduction. Heavier, bulkier but still very comfortable over long periods (10 hours a day in aircraft use) due to thick confor foam. Warranty has be tested and works. (Telex promptly went beyond the call of duty and replaced ear seals as well as telling I didn't need a receipt). Sennheizer ANR seemed about the same as DC ANR but very much less well built. Passive not tested. Overpriced and I have heard of warranty problems (huge time delays among others). If cost no object, Telex 50D is the best for hearing protection (and yes you can still hear the engine) Bose is best if you are tall and have no headroom (and want style). Limitations: could not test Lightspeed, DC, or Bose against each other, only compared to the constant, Telex.

From: "Frank van der Hulst (Staff WG)" --> RV-List message posted by: "Frank van der Hulst (Staff WG)" > I'm not sure how the capacitance vs regular float type senders differ. Hugely! See Jim Weir's Kitplanes article at http://www.rst-engr.com/rst/articles/KP89SEP.pdf for details of how a capacitance-type sender works. Here's my summary. A capacitance sender is immersed in the fuel, and measures 'capacitance' (an electrical property) between two plates. The capacitance depends on the 'dielectric constant' (DC) of the material between the plates. Air's DC is 1, avgas is about 2. Basically, the amount of capacitance is proportional to amount of fuel. The capacitance effect of auto fuel varies depending on what's in the fuel, and in what proportions. For example, alcohol has a DC of 25. If you have autogas which is 1/8 alcohol, a capacitance guage will read about two times as high as for avgas (i.e. if calibrated for avgas, it will read full when the tank is half-full). How large the error is depends on the proportion of alcohol, and the DCs of the other components of the fuel. Note that some cars have capacitance fuel senders in them (http://www.datcon.com/products/4intelli.htm). A float sender will also read about 2% high if it is in 1/8-alcohol mogas rather than avgas, due to the difference in density of the fuels. If the float is gas-filled, then air pressure will also change the reading. But I'd guess that in the presence of the huge inaccuracies inherent in a float sender installed in an RV tank (reads full if the tank is over, what, 3/4 full, errors due to slope when on the ground or to unbalanced flight), these difference wouldn't be significant to most pilots. Incidentally, a couple of benefits of capacitance senders are 1. They can be made any shape so that (a) they can go right from the bottom of the tank to the top, and (b) the output is proportional to the amount of fuel, not the height of the fuel 2. They can be used to detect water in the tank (because water's DC is 78, even a little water will give a 'vastly overfull' reading). In fact, in any aircraft, there's no reason why a capacitance-based water-detector couldn't be put into each tank. > If one is worried about additives in the gas one buys, one can call the manufacture, > or maybe even the distributor, to find out what additives are used.

My impression is that the problem isn't so much the engine as the plastic and rubber things that the fuel comes into contact with. Some years ago, I was working for a petrol pump (as in gas station pump) manufacturer when NZ switched to 'unleaded' (ie low-lead, with additives to raise the octane rating) auto fuel. We had problems with gaskets swelling and leaking and so on. Various problems also occurred in cars with plastic fuel lines dissolving and gaskets swelling/disintegrating. At that time, several planes running mogas had engine/fuel problems caused by the same things, to the extent that CAA banned use of mogas in aircraft until the issues had been sorted out.

I went through "Headset Hell" a year ago when trying to decide what to buy to replace my ANR DC's. I researched all of them and demoed every brand I could get my hands on. I ended up going with Lightspeed 3G-30's. Bose: As everyone has stated... Wow! But I'm not spending $1K on a headset, not yet anyway. DC's, they all squeezed my head, and/or put pressure on my ears. Great for 1 - 1.5 hours, then becomes painful. All others I tried I found either uncomfortable or did not have the level of ANR I wanted. Lightspeed: I find I can wear them for hours and am completely comfortable. The ANR is great, good battery life (25-30 hours), and as stated by other the Sound quality has to be heard to be believed. ***Quote*** I honestly don't know if the price difference for the 30-3Gs over the 20-3Gs is really worth it for the extra 2 or 3 dBs of noise canceling. ***End Quote*** YES it is! I originally bought a pair of G3-20's, flew them for an hour. I promptly exchanged them for my 30's. That last little bit of Noise Reduction (for me anyway) was worth the $100. FWIW, none of my flying has been done in RV's (yet) so your results may vary. I spend the majority of my time in a 172RG, 182 (Skydiver airplane, NO insulation...), Cherokee 140, Cherokee 180, and an Arrow 200. All of which, with the exception of the 182, I'm sure are quieter than most RV's. Now for my question. I've see several posts by different people that claim the Lightspeed's are not as durable as other brands. Is this based on appearance or have people actually had problems with them? I've had mine for just over a year (260 Hours), do not baby them, but do not abuse them either, and they look / function like the day they where new! Maybe I'm missing something?

Turns out I must have large ears because every other headset I tried clamped part of my ear against my head, or pushed againt my ear in some way. My old DCs do this too. The lightspeed 3G series has a lot of room within the ear cup so the phones clamp against my head, not my ears. The ear cups are leather-covered confor or temper foam and temperature-mold to your head. Other good & bad points about the 30-3Gs: 1. The ANR noise cancelling works great. One of the best in the business according to the specs. I honestly don't know if the price difference for the 30-3Gs over the 20-3Gs is really worth it for the extra 2 or 3 dBs of noise cancelling. But I figured, what the hell...it was my Oshkosh gift to myself :-) 2. Passive noise cancelling is not so great. The ANR removes the low end noise from the prop and engine, but the white noise from airflow around the canopy is still more than I would like. I think a lot of other headphones are better in this regard, including my old passive DCs. 3. The mike is pretty good, but not as good a David Clark. 4. I seem to get 20 hours+ out of a set of two AA batteries, which is good enough. When DC went to the 9v battery pack, I lost a lot of interest in their ANR products. I prefer battery power for portability to other aircraft, and AAs are dirt cheap if you buy the big strip packs. 5. While you just can't beat DC for quality and ruggedness, the Lightspeeds have held up fine so far. Mind you, I try not to step on them when I climb into the plane, or chuck them around. They don't look particularly robust. 6. The sound quality of the 3Gs is awesome. This was the tipping point for me. These things sound as good as the studio monitor headphones that I use for my music recording work. 7. The ability to plug a CD or mp3 player directly into the headphones is a fabulous feature. My intercom isn't hi-fi and my wife isn't interested in listening to my music at my volume anyway, so I seldom play music through the intercom. This direct plug-in feature, along with the bass/treble boost options and the overall sound quality make these great headphones for music-loving pilots. 8. The ability to plug a cell phone into the headset is another feature I'd never want to give up. It's great to be able to tell your wife from 8500 feet a hundred miles away that you'll be late for dinner and not to initiate any search for you. Frankly, Lightspeed sets the mark in terms of features and sound quality for me. As for comfort, that is a personal thing and you have to buy what fits your head the best. I'd say that the other manufacturers are going to have to reproduce the features of the 30-3Gs if they ever want to get my business again.

I'd say that the other manufacturers are going to I really loved the Lightspeed headset - unfortunately the headband is so thick that I kept hitting it on the top of the canopy. So I went with the Bose X due to the thinner headband and of course the quality. None of the other headsets I tried even came close to the LightSpeed or Bose for comfort and noise reduction. -Dj ________________________________ Message 32 ____________________________________ Time: 07:11:32 PM PST US From: "Brian Kraut" Subject: RE: RV-List: Noise Canceling Headsets - Was Stop the Noise --> RV-List message posted by: "Brian Kraut" Unlike the old analog towers, the newer digital towers have high gain antennas with very narrow beam widths. Their antenna beams are only a few degrees wide so you are out of the beam at altitude.

As a flight instructor I have the opportunity to do side-by-side testing of various headsets with my students, who have a variety of headsets. I only tested ANR sets Immediate switching of headsets back and forth under same flight conditions (RPM, Airspeed, Aircraft are constants). I use Telex Stratus 50D. Compared with: David Clark ANR, Lightspeed 3g (and lesser models of lightspeed), Bose X (latest), Sennheizer ANR. Conclusions: David Clark are toughest but also have the least ANR noise reduction, but best Passive noise reduction and possibly the best warranty (I'm sure up for debate). Lightspeed have very good noise reduction, but are not as toughly built as the others, best ANR for the buck but passive noise reduction is poor (due to thin ear seals I believe). Bose is most stylish, lightest, least bulky and ANR is very good, like Lightspeed's ANR, but with better Passive noise reduction. Very noticeably not as good as the ANR in Telex 50D. Telex 50D very noticeably better ANR than all tested with only the David Clark having better Passive noise reduction. Heavier, bulkier but still very comfortable over long periods (10 hours a day in aircraft use) due to thick confor foam. Warranty has be tested and works. (Telex promptly went beyond the call of duty and replaced ear seals as well as telling I didn't need a receipt). Sennheizer ANR seemed about the same as DC ANR but very much less well built. Passive not tested. Overpriced and I have heard of warranty problems (huge time delays among others). If cost no object, Telex 50D is the best for hearing protection (and yes you can still hear the engine) Bose is best if you are tall and have no headroom (and want style). Limitations: could not test Lightspeed, DC, or Bose against each other, only compared to the constant, Telex. Chris Carpenter RV-8, Wings Chris, et al: I would be interested in your take on the Sigtronics ANR equipment. I have a set (2)and use them in my RV-4. I regard them as very good but have no real basis for comparison, other than sampling different systems at Oshkosh, etc. At my request Sigtronics provided a ship's power adapter, complete with bayonet power connectors that fit in place of the battery packs which I still possess. They are hot whenever the electrical system is up and have no problem dealing with voltage swings when starting the engine. The passive noise reduction seems to be about the same as their non ANR sets. I have used them on long flights and find them entirely satisfactory. Pity they are rather ignored by the flying community.

Is this based on appearance or have people actually had problems with them? I've had mine for just over a year (260 Hours), do not baby them, but do not abuse them either, and they look / function like the day they where new! Maybe I'm missing something? ================================ Nick- Yes, but you can look forward to returning them to Lightspeed Aviation for intermittent cords, broken stirrups and sacked out headband springs. The good thing though is that they will do all of these repairs for FREE because they really stand behind their products. I still believe that my five year old 20Ks (copilot's) and my two year old 25XLs (mine) are very good values.
