I have no noise in the radios, even with the squelch open. My RV-6A is a full IFR plane. The key to no noise in the radios is proper placement of the EL Inverter, and good wiring practices. The EL inverter should not be placed near the radios. I have mine mounted on the right side if the tip-up canopy, far from the radios. The EL inverter ground should go to the airframe, where it's ground currents will not be mixed in with the ground currents of radio power leads. It's power lead should also be kept away from radio leads. Sometimes, as small capacitor (.01 uF) is needed near the inverter, to keep noise currents circulating near the inverter. When using an EL panel with digital dimmers, you can sometimes get a beat frequency flicker in the EL panel. (The beat frequency is the difference between the inverter freq and the digital dimmer freq.) This can also be mitigated by installing a 100Uf cat near the inverter, or by changing one of the frequencies....

First off most people just assume that all you need is the inputs and a simple computer. Well there are other considerations you have to look at. For example will the unit operate in Alaska at extremely low temperatures and in Arizona at extremely high ones? OK so now you need industrial temperature electronics, well that eliminates most all common off the shelf hardware. Now start considering what happens when the guy wiring up the unit accidentally connects 12V or 28V to one of your input pins. Or if even worse he connects the P-lead to the oil pressure input. How about more basic questions like what operating system do you use? For example if you use a Windows box are you willing to wait for the system to boot up? What about power supply, should it operate while cranking the engine? Should it operate at 28V? Once you got this questions considered think about how many you will sell. Today there are about 1200 experimental aircraft registered each year. Thus if you sell 10 units a month you have 10% of the market, which is not a lot of sales but a large part of the market. Like Tracy said you will have a significant amount of development expense in each unit thus the units will not be cheap as the volumes will not be high. You also have competition out there, so what are you going to do different than them to get the customers to buy your product. My thoughts were that giving the user control over what the unit would be of value to customers. What I found is that a most people who want to do some special things, like one guy wants to hook up a speed sensor to the wheel to measure take off distances. Another guy wants to hook up weight sensors on the landing gears and calculate weight and balance before each flight. Another guy wants to have the ability to set cruise alarms that notify them if anything changes more that 10% while at cruise. One guy even wants to monitor his Subaru's injector on time to calculate fuel flow. Thus from talking to people what I found was everybody wanted to do something a little different on their plane. Thus I designed the Pulsar unit such that it can read almost any sensor and then do any calculations the user wants on the sensor and display the data. However the people who wanted to do this really wanted someone to do it for them, for free. My mistake was that I should have asked how much would you be willing to pay to get the features you want, and would you be willing to do some work to make it happen? So if you want a "trend monitoring" engine monitor, how much would you pay for it and if you could do it by configuring a unit would you be willing to do that configuring work? The Pulsar unit I am shipping can do it, but it is not free and it will require work on your part.

In the context, you seem to be suggesting that this fact indicates an RV taildragger is more likely to be involved in a wreck than an RV nosedragger. But I think you'll find that the actuarial data used isn't that fine-grained. If RV taildragger insurance is higher it's almost certainly because taildragger insurance is IN GENERAL higher, not because RV taildraggers, specifically, represent a higher risk.

To get free shipping, I ordered 3 EL kits to get the total over $25. The red ones were cheaper -- about $8.95, than the green ones, and I thought I may want red anyway, so I ordered 2 reds and one green. The green EL tapes are brighter than the red, and much more efficient (see below). And my 2 reds were different colors. One was almost purple, and not near as bright as the other red. Also, all three inverters were different. One was much smaller than the other two. The dimensions of the larger ones are 1 3/4 by 1 by 15/16 high, not counting the mounting ears. The smaller one is 1 1/16 by 11/16 by 13/16 high. The inverters have 2 cables and connectors to drive 2 tapes, so maybe you can buy the tapes separately. The package has some specs on the inverter. The input is 12V and has a connector which mates to a disk drive power cable in the computer. The output is 90 VAC at 1 KHz. I measured the input current on one of the inverters driving each strip as: green 28 mA, red 64 mA, and purple 32 mA. When driving no strip at all the current was 15 mA. The current is less at lower voltage. This limited testing shows that the green is much more efficient. The point is that there is a lot of variation between the different colors. Of course, I don't have enough strips to be sure that my data is typical of all the parts. The width of the strip according to the package is 0.3 inches, but they measured 0.4, 0.5 and 0.55 inches! The 0.55 inches was because of sloppy assembly, the two outside clear tapes were offset from each other. The length is (almost) 5 feet and can be cut off, but I don't know how you would connect to the unused piece to use it again. At Delco we had some conductive epoxy which would work, but I don't know where to get it now, and its probably expensive. Does anyone know? Short pieces may come in handy to light instruments, switches, etc. I'm not unhappy with these EL lighting strips. I think I will make use of at least one of them, and the price is great.

I understand that some people build the wings without jigs now. Maybe Vans even recommends it, I don't know. BTW I couldn't make out the wave for sure in your picture, probably because I didn't know exactly where to look. If its the trailing edge, why would you roll that? Instead of rolling edges, I found that I can taper the last 1/8 inch down to about .015 and it looks rolled, but looks nicer, kind of like a scarf joint. Just put the skin right at the edge of the work table and file away. It does take a little time, but the results are worth it. I didn't do it on the wing, but did it on the fuselage where the .032 skins end.

I continued with the process of bonding the skin to the AEX wedge hoping that it would straighten up, but as soon as I started back riveting, the waves reappeared. It was a big mess, and afterwards I wished I had cut my losses early, because I wasted a perfectly good right skin and AEX wedge. So, I ordered two new skins and wedge, and since then I haven't edge rolled any of the trailing edges on the empennage.

Please keep us informed about your progress with the Renesis engine. Bill Dube Bill, I have not installed the Renesis yet but here is a synopsis of the testing done in preparation for it. This is a collection of messages and replies sent to a rotary engine discussion group so it may sound a bit choppy. I'm just now starting on my Renesis evaluation. First I wanted to compare it to the earlier rotary (89 vintage) so I installed the RD-1C 2.85 : 1 drive and larger prop [74 x 88] (intended for the Renesis). Things are different enough that it will take at least 20 hours to evaluate. I'll be posting detailed reports on the website. On the second flight test of this configuration I had planned to do a maximum performance takeoff to see how it compared. I was fully aware that the P-factor would be opposite (prop turns right instead of left) but I was unprepared for the magnitude of it. With full right rudder the plane was still veering left. Things happened too quickly for me to be exactly sure of what happened next but I think when the tail wheel lifted off, the plane turned sharply to the left and I was certain that I was going to crash into the fence that borders the runway. No one was more surprised than I when the RV-4 lifted off and cleared the fence (barely!). There were lots more interesting differences (most of them good) but it will take several pages and more time than I have right now to explain them. My first recommendation when using the -C drive and a big prop is Feed in power gradually on takeoff until rudder is fully effective. A bit of right offset in the engine mount might also be in order (mine has none). Tracy ( Ed Anderson asked for some comparison fuel burn numbers) Hi Ed, Wish I had more carefully documented fuel burn vs airspeed on the -B drive & old prop. But from the few well documented points that I have, it looks about the same at 6.0 GPH (sea level) IAS, 143 - 148 depending on OAT, humidity, etc (its amazing how much conditions affect things). This is the only point I've had a chance to compare so far. I have not built the prop blade cuffs that I feel will be necessary to get best performance from this combination. Clark at Performance Props was very honest about the difficulty in getting the proper pitch at the blade root (out to ~ 3" past the 13" dia. spinner) with pitch this high. This being the case, I'm very happy with the results so far. Other conclusions are that anything less than 74" L prop is a waste on the -C drive. More would be better but that's as long as the -4 prop clearance would allow. I can't measure static rpm (plane wants to skid on grass and/or nose over) but climb RPM is at 6200 at 120 mph (up from about 5200 with -B drive) and VSI is pegged (hard!). Only did very brief test of WOT in level flight and engine hit 7050 rpm. IAS was still climbing at 215 mph. Oil cooling has suffered due to stalled air around prop hub and reversed spiral of airflow due to RH prop. Erased several years of tweaking inlet shapes. Most unexpected finding so far is the radically improved glide at idle setting. Have no clue why. Would have expected worse instead of better. Tracy The -C drive has very different internals but I will look at the feasibility of reworking the -B housing to receive the -C guts. I think it can be done. Yes, the -C bolts right up to the same adapter plate. I think you are right about the 2.85 becoming the preferred ratio, but only if you can handle the longer prop. You nose draggers have the advantage here The more I fly it the better I like this setup. The higher rpm was very disconcerting at first but I acclimated rapidly. And now that I have digested the fact that the actual rpm difference at normally used throttle settings is only about 5%, I absolutely love it. Another good sign is that the manifold pressure is now more than 5% lower at any given airspeed that I've tested so far. Even if the wear rate is up 5% or so it would be a non issue. One more plus for the 2.85 is something I hesitate to mention. It's kind of like the "engine making oil so I have to drain some out" thing, kind of unbelievable. It makes sense that there would be less prop noise but I'm also getting less engine noise. I was getting tired of the increased noise with the Hushpower II muffler and was almost ready to put the Spintech back on even though it costs at least 5 - 6 mph in drag. But with the -C drive things have quieted down substantially. I think part of the credit for this goes to the difference in RPM moving the vibrations away from the resonance point of the sheet metal panels in my RV-4 but even observers on the ground have mentioned that the engine sounds quieter. I better shut-up now, this is starting to sound too good to be true. Tracy The following message was a reply to a wise crack by Finn Lassen saying that Paul Lamar was right all along (about the best ratio being higher than the 2.176 : 1 that I used previously) OK, OK, rub it in, but before you guys get carried away, consider the following: The prop limitation was always my only reservation about using the higher ratio. I must emphasize that in order for this to work, the prop must not only be long but has to have a good profile as far down toward the root as possible with the MUCH higher pitch. I worked with Clark at Performance Props and emphasized this. It required a thicker than standard hub to get close to what was needed (and it still needs the previously mentioned cuffs). If you don't do these things, all you get is significantly higher rpm, less performance, higher fuel burn and higher wear. Look at the numbers from previous users of the 2.85 drive. Did I mention the three spinners, various spinner bulkheads, prop bolts that were now too short and other various things that went wrong during the effort to make this work right?

Simply remove the drill bit from the chuck of the drill and take the chuck end (no drill flutes) of the drill, insert into drilled out rivet head and briskly snap off the head using the drill bit as a "break off tool".

Finally got to use my new box of DeVilbiss E-Z Liners this weekend. Its an innexpensive kit with zip lock bags and inserts that go into the neck of any gravity feed HVLP gun. You insert a receptical into the base of your guns cup, then put an insert into the bag, you poke the two together with an insert tool. Pour in your paint, zip the bag closed with the help of the zipper tool. Turn the gun upside down and spray until paint comes out. Once the gun is drawing paint, you can paint in any direction with absolutely no difference (that I observed) in the way the paint comes out. You also don't have to clean out your cup when you are done. Fits all guns. This weekend I shot the bottom of a 6A and this worked out great with my Sharpe SGF gun. The cost is about 25 bucks which beats the stink out of buying a pressure pot to paint the bottom surfaces. Here's a link. Do a search for E-Z liners in the gun cup section.

Ed Bundy - Eagle, Idaho RV6A 600+ hours <<<<<<<<<<<< I couldn't agree with you more than I already do about checklists and process. But even with twice checking, I have left the canopy unlatched and aborted a takeoff. My point was if you can accomplish something in a fashion that doesn't leave the plane disabled, or makes it impossible to even get in the airplane until you reable it then you have one more level of redundancy that is good for our health. On the other hand, experience/history tells us that if a procedure which is regularly used, disables the aircraft, it can/will eventually lead to an incident. So therefore safety demands that we reduce these types of procedures as much as possible, and where not possible we conduct the procedure in a failsafe manner if at all possible. (IE can't open the canopy, can't get in the airplane, engine won't start, etc) So a better choice than a rudder lock would be a set of rudder trim springs or rubber stops that allow the rudder to move but prevent or reduce wind banging of the rudder. If you must have a rudder lock then it can be a piece of rubber gap seal with two short pieces of hard rubber hose stuffed through it, inserted into the counterweight horn gap, and a piece of string that runs from it to the canopy cover, or prop tip so you have to remove it just to climb in. If that fails, along with your checklists than the rubber should allow you to flex the rudder some, and maybe pop the lock out.

Please keep us informed about your progress with the Renesis engine. Bill Dube Bill, I have not installed the Renesis yet but here is a synopsis of the testing done in preparation for it. This is a collection of messages and replies sent to a rotary engine discussion group so it may sound a bit choppy. I'm just now starting on my Renesis evaluation. First I wanted to compare it to the earlier rotary (89 vintage) so I installed the RD-1C 2.85 : 1 drive and larger prop [74 x 88] (intended for the Renesis). Things are different enough that it will take at least 20 hours to evaluate. I'll be posting detailed reports on the website. On the second flight test of this configuration I had planned to do a maximum performance takeoff to see how it compared. I was fully aware that the P-factor would be opposite (prop turns right instead of left) but I was unprepared for the magnitude of it. With full right rudder the plane was still veering left. Things happened too quickly for me to be exactly sure of what happened next but I think when the tail wheel lifted off, the plane turned sharply to the left and I was certain that I was going to crash into the fence that borders the runway. No one was more surprised than I when the RV-4 lifted off and cleared the fence (barely!). There were lots more interesting differences (most of them good) but it will take several pages and more time than I have right now to explain them. My first recommendation when using the -C drive and a big prop is Feed in power gradually on takeoff until rudder is fully effective. A bit of right offset in the engine mount might also be in order (mine has none). Tracy ( Ed Anderson asked for some comparison fuel burn numbers) Hi Ed, Wish I had more carefully documented fuel burn vs airspeed on the -B drive & old prop. But from the few well documented points that I have, it looks about the same at 6.0 GPH (sea level) IAS, 143 - 148 depending on OAT, humidity, etc (its amazing how much conditions affect things). This is the only point I've had a chance to compare so far. I have not built the prop blade cuffs that I feel will be necessary to get best performance from this combination. Clark at Performance Props was very honest about the difficulty in getting the proper pitch at the blade root (out to ~ 3" past the 13" dia. spinner) with pitch this high. This being the case, I'm very happy with the results so far. Other conclusions are that anything less than 74" L prop is a waste on the -C drive. More would be better but that's as long as the -4 prop clearance would allow. I can't measure static rpm (plane wants to skid on grass and/or nose over) but climb RPM is at 6200 at 120 mph (up from about 5200 with -B drive) and VSI is pegged (hard!). Only did very brief test of WOT in level flight and engine hit 7050 rpm. IAS was still climbing at 215 mph. Oil cooling has suffered due to stalled air around prop hub and reversed spiral of airflow due to RH prop. Erased several years of tweaking inlet shapes. Most unexpected finding so far is the radically improved glide at idle setting. Have no clue why. Would have expected worse instead of better. Tracy The -C drive has very different internals but I will look at the feasibility of reworking the -B housing to receive the -C guts. I think it can be done. Yes, the -C bolts right up to the same adapter plate. I think you are right about the 2.85 becoming the preferred ratio, but only if you can handle the longer prop. You nose draggers have the advantage here The more I fly it the better I like this setup. The higher rpm was very disconcerting at first but I acclimated rapidly. And now that I have digested the fact that the actual rpm difference at normally used throttle settings is only about 5%, I absolutely love it. Another good sign is that the manifold pressure is now more than 5% lower at any given airspeed that I've tested so far. Even if the wear rate is up 5% or so it would be a non issue. One more plus for the 2.85 is something I hesitate to mention. It's kind of like the "engine making oil so I have to drain some out" thing, kind of unbelievable. It makes sense that there would be less prop noise but I'm also getting less engine noise. I was getting tired of the increased noise with the Hushpower II muffler and was almost ready to put the Spintech back on even though it costs at least 5 - 6 mph in drag. But with the -C drive things have quieted down substantially. I think part of the credit for this goes to the difference in RPM moving the vibrations away from the resonance point of the sheet metal panels in my RV-4 but even observers on the ground have mentioned that the engine sounds quieter. I better shut-up now, this is starting to sound too good to be true. Tracy The following message was a reply to a wise crack by Finn Lassen saying that Paul Lamar was right all along (about the best ratio being higher than the 2.176 : 1 that I used previously) OK, OK, rub it in, but before you guys get carried away, consider the following: The prop limitation was always my only reservation about using the higher ratio. I must emphasize that in order for this to work, the prop must not only be long but has to have a good profile as far down toward the root as possible with the MUCH higher pitch. I worked with Clark at Performance Props and emphasized this. It required a thicker than standard hub to get close to what was needed (and it still needs the previously mentioned cuffs). If you don't do these things, all you get is significantly higher rpm, less performance, higher fuel burn and higher wear. Look at the numbers from previous users of the 2.85 drive. Did I mention the three spinners, various spinner bulkheads, prop bolts that were now too short and other various things that went wrong during the effort to make this work right?

If you go to higher frequency input (higher RPM) you should get greater attenuation. Typically, they are more than 1st order filters, so you should get much more than 20 dB per decade. Also, you are making less energy per combustion cycle. (The HP demand is the same, but you are running at higher RPM.) This should reduce the peak combustion pressure and the concomitant pressure fluctuation at the exhaust port. The muffler becomes more effective and the pressure pulses are reduced in magnitude. You can't help but reduce the noise. ________________________________ Message 29 ____________________________________ Time: 01:29:08 PM PST US From: Fiveonepw@aol.com Subject: RV-List: Sun-n-Fun Arrival times --> RV-List message posted by: Fiveonepw@aol.com Are any times better than others to arrive at LAL midweek?

I guess I must be doing my control locks all wrong and am totally unsafe to myself, my passenger, and my RV. In this thread, I've read some pretty ingenious methods of tying things down in our RVs. I'm sure all work to help each of us to feel better about his/her own self. As for me, I think I'll still use the simple method of putting the lap belt over the stick and cinching it down to hold the ailerons and elevator. I've been doing that for four years on a ramp that can get pretty darned windy. I can't help but believe that my RV, which is buillt much stronger than the spam cans nearby, can withstand any loads on the elevator that those winds will impose. Forget not that we fly much faster and must impose more loads in normal fligh regimes. Now, that's pure speculation on my part; but, I can't visualize it being any other way. Unless my RV is hit by a tornado, I can't believe the wind is going to ruin my RV's elevator, or even slam the tail to the ground. If it's a tornado like wind, I think I have more to worry about than just the elevators. Am I the only one thinking this way? If so, maybe I'm way off base on the subject. As for my solid rudder stop that locks the rudder horn to the rudder stop, I can assure you that I know about it as soon as I get ready to start the engine and place my feet on the rudder pedals. The rudder pedals are rock solid and won't move. That's a heck of a lot easier to recognize than some idiot light that I might forget to look at. Another thing I do is put the rope to my cowl plugs around one blade of the prop as I put them in the cowl inlets. That way, the prop will sling the plugs out, if I do forget to pull them out. Now, it doesn't take rocket science to do this. I just angle the blade at about 45 degrees to keep the birds from resting on the prop. If I put the cowls straight in without putting the rope behind the blade, the job is done. I can't start that engine without slinging the cowl plugs out. I've tried it to see if it works. Yep. No problem, there. I also tie my pitot cover to the tie down ring with the rope so it comes off when I remove the rope. Simple. I know if I forget the rope, the airplane won't move from that spot. Sorta idiot proof, again. My goodness folks, where the heck is the KISS method going to? You guys are just making it too hard for me to go flying. I think I'll just stick by what works well for me. Thanks for the very informative thread, though. It's been interesting to see what we can come up with, I must say. Jim Sears in KY RV-6A N198JS (Scooter) RV-7A #70317 (Tail almost built.
