I don't believe the flaps are blanking the elevator, but putting more flaps down does increase the nose down pitching moment. So the more flap you extend, the more up elevator you need. The archives are full of reports from people who say that the RV-8 is difficult to three-point if the CG is near the forward limit. You run out of elevator in the flare. I believe that having a CS prop may also make things worse, even at the same CG, as it may blank the tail a bit more than a FP prop. For the first few flights, it may be wise to use some ballast to put the CG near the middle of the recommended range. After a few flights you can start adjusting the amount of ballast to slowly explore the forward and aft CGs.

As Kevin noted, near the middle CG range is likely to be safer.

Capen" Subject: Re: RV-List: Craftsman Compressor Help --> RV-List message posted by: "Ralph E. Capen" I have a similar compressor - I'll look at it this weekend - I also think I still have the documentation that came with it....If I do, I'll let you know. From memory though the wiring has three wires - for 220 there are two lines(one white, one black) and one ground(green), for 110 the wires go line, load (don't remember which is line or load), and ground(green). The house wiring determines the phase of the individual line feeds - your house should have two line feeds to run AC/dryer etc and the 220v feed would already be wired according to code by your electrician. I'm guessing that you have a 110 outlet available and don't want to run 220V?! Keep in mind that 110V will not produce the HP rating that is advertised for the compressor (unless they're advertising under 5hp). It'll still work - just run a little longer per duty cycle. Been there - done that - installed a 220V feed for my compressor.

For example, if I wanted add 25 pounds to the rear baggage shelf and 50 pounds to the rear baggage floor, what are some safe ideas that won't hopefully lead to the ballast crashing through from the back and hurting me should I have an off field event. For the first few flights, it may be wise to use some ballast to put the CG near the middle of the recommended range. After a few flights you can start adjusting the amount of ballast to slowly explore the forward and aft CGs. Kevin Horton RV-8 (finishing kit) From my non-aeronautical engineer view that would not be ideal. As Kevin noted, near the middle CG range is likely to be safer.

The reason for posting more details of my experience, is to help those who might someday find themselves in my situtation.. My medical was to be renewed at end of July 04..So I thought I would be smart I take my medical earlier, which I did, first week of July had the Medical. Same day, I personally, mailed the medical records I had, which were two pages both Lab work, one for the liver fuction, I take lipitor (the only thing I take) the other page for the heart electrolites or whatever... Also, I fax them, with a note, the medical was completed etc.. One month past, then I called FAA., the answer, could not find any records, to wait. I will not bore you with all the details that happened during the next two months, you would not believe me any how, the answers I got from FAA, The fact is that at the end of September, they said, never received papers... nor even the fax.... Here is when I learn,,I decided to call AOPA for the first time... they aske me then to send them copies of everything I had sent to FAA, including cover letters etc...which I did ( I do not know if one should send all medical records to them, but they asked for so I did) 2- They asked that I mail everything again to FAA, but this time register mail, return receipt, and not to the P.o. Box but to the Macarthur,BLVd. address. IN four days I got the signed recipt, and 2 weeks later got first reply from FAA.. So there you are, Send everything certified, and call Aopa right at the beginning... During the next months, they keep asking form more things, including things they had, from last renewal, maybe they do not keep records? I had to get records, all, from 3 years ago. Finally on November of 04, they asked that I take an Echo Cardiogram, which I completed in December, it was mailed Registered, copy to Aopa. Why the did not asked for it, back in August? So here I am, seven months, no being able to fly, the worst part is that I was in the middle of my test flights, needed 40 hours... I hope that one will go thru this, you would not believe the way FAA works the answers I got, are unreal... by the way how is that my mail was lost, but the AMA, mail which is not sent register, never gets lost ????

Depending on her age, it doesn't have to be an either-or. The RV is going to be worth more completed than sold unfinished. So if the object is to have more money than you do today... the best way to do that is finish the project. Selling it -- especially at cost -- doesn't give you more assets, it gives you less. Unless your daughter starts college this September, you can win by keeping your options open. So take out a loan and finish it. And then sell it if you still need the cash. That helps in two ways. First, when it comes to scholarship eligibility, the school and others are going to nick you for having assets. The loan is debt against the assets, giving you -- possibly -- an advantage in getting financial aid. Second, of course, it gives you the cash to finish the project at below market value, and then allows you to sell it and use the gain to finance her education. If you sell it now, especially at cost, you end up financially back where you were when you started the project. If you continue, there's no way you don't come out financially better off unless suddenly there's no market for RVs. Think about it.

It did, but I got two different airspeed indications & I'm wondering if the UMA unit I bought from Vans can be adjusted. The UMA said I was using a 103 kt balloon but the Dynon D10 said I was using a 109 kt balloon. Have any of you observed differences like these? Which was the most reliable? Anyone know of a book full of numbers and equations that would give me the air pressure that corresponds to 110 kt?

They don't seem to use the dual 110/220V motors anymore. Probably because of cost. Mine is older and can be wired either 110V or 220V, once you figure out the secret..... The funny thing is on my internet search, I found a note from a Sears technician asking the same question! He apparently could not figure it out either.

I attached these to the #8 screws that hold the baggage area in place. Then I can attach tie down straps to them to hold everything in place. For the first few flights I strapped 25 lbs in the back to get the CG to the mid point. Had no trouble three pointing. But I have an O-320 so even solo with nothing in back my CG is an inch back from the fwd limit. I have no problem with full stall three point landings, but wheel landings are so easy in the -8 that is what I do if there is a crowd watching.

David, If all you want is the formula, you can get it at: http://www.eaa1000.av.org/technicl/instcal/instcal.htm If you want an Excel spreadsheet I created that converts between ASI reading and pressure in inches of water, you can get it at: http://www.kilohotel.com/rv8/filemgmt/visit.php?lid=3 I've got other useful flight test links at: http://www.kilohotel.com/rv8/phplinks/index.php?PID=1 Just for info, the results of my ASI calibrations (Dynon D-10A and analog ASI) are at: http://www.kilohotel.com/rv8/article.php?story=ASI_Calibration_2 2 - 3 kt ASI instrument errors are very normal. Five kt errors are not unusual. Plus there is some friction in the instruments, which gives some hysteresis. I.e. the ASI number might have increased a kt or two if there was some vibration, like you would get from your engine.

Neal, The last e-mail I had from Doug ( a few weeks ago), indicated that he no longer monitored the RV-List. His departure seemed to follow a period in which the signal to noise ratio had gotten quite low. It is a shame, as he had a lot of valuable experience to pass on.

It did, but I got two different airspeed indications & I'm wondering if the UMA unit I bought from Vans can be adjusted. The UMA said I was using a 103 kt balloon but the Dynon D10 said I was using a 109 kt balloon. Have any of you observed differences like these? Which was the most reliable? Anyone know of a book full of numbers and equations that would give me the air pressure that corresponds to 110 kt? It seems to me that a test pilot oriented book of that sort would be pretty useful during the coming months.

When I did my fly-off, I put the bags o' birdshot into duffel bags and used the handles and straps on the duffel bags as tie-down points to secure the load to the airplane. Also, I thought that if I managed to break one of the shot bags, the duffels would retain the shot, so I wouldn't have to dig 25 lbs of steel shot from all the nooks and crannies in the fuselage. In addition to making good ballast, you can use the shot bags as to back-up aluminum if you're trying to stretch form it with a hammer.

I foolishly had the engine mount modified and had Airflow make a couple of custom elbows to allow me to mount the Injection under the sump. I may have some digital pics of this installation, but I DO NOT recommend what I did. If I had it to do over again, I would buy a more std A1A type sump and have a much easier time. I believe the Lancair folks used to buy the rear carb mount sumps and modify them, so you may be able to sell the sump. My A2G did indeed have a hollow crank, plugged to run a fixed prop. I ran it fixed for 500 hours and then changed to C/S. The fitting that 'W' mentioned as may not be there in fact WAS there on my engine and the conversion was no problem. I do suffer from a hard to locate Oil leak, could the issue mentioned about the lower studs on the governor be my problem? I will certainly give it a try!! So swap out that sump and go for it!

The instructions that came with it state the following: "CAUTION -- Before rewiring the motor for operation at 115 volts, the following items must be changed or checked. 1. The motor cord and plug and the pressure switch cord must be changed to minimum of #12 gauge wire. The plug must also be changed from 230v type to a 115v type. 2. The supply wiring plug, and protector should be capable of handling a minimum of 20 amps and meet all local electrical codes for this minimum. Instructions for wiring the motor for operation at 115 volts will be found printed on the inside of the motor terminal cover."

(Sam, Dan?) You've got the basics covered. Here's some other suggestions: 1. Find a heavy hunk of steel about the size of the base of your camera. Drill a hole through it of appropriate size, and screw it into the tripod mount on the bottom of your camera. Put a couple of felt protective "feet" in between the camera and the steel to protect the camera. And be careful to not screw the bolt into the camera too far. You may need some washers. This will increase the weight of your camera, and with the weight it's stability. 2. Increase your shutter speed. 1/200 or 1/250 is good for getting a nice prop sweep, but is hard to hand-hold with a point-and-shoot camera, even with the extra weight. 1/500 will sharpen things up a bit, and still leave *some* prop sweep visible. 3. Tell #2 to tighten it up. You want to be shooting the camera with the zoom somewhere in the middle of it's range. The zooms on digicams don't really get enough light at full telephoto, so you have to open the aperture to get more light to the sensor, which robs your depth-of-field. You may find that what looks like camera shake is just a blurry photo because the focus isn't exact. 4. Finally, focus. The autofocus on digicams isn't the most reliable. There are distinct "steps" in the autofocus, and it's possible to get your subject in between two steps. At one it's out of focus, and as it moves to the next step it gets sharp and then goes out of focus again. Having the largest depth-of-field you can get helps with this. Taking a dozen photos one after the other as the planes jockey for position around one another also helps... One good photo in 12 and you're doing as well as many pro photographers. Here's my last air-to-air mission, coming up on two years ago: http://b4.no-ip.org:8080/airframe/events/20040417_CYGB/thumb3.html All photos were taken with a Nikon Coolpix 8700, with the extra battery pack/vertical grip (the extra weight is like having the steel lump I suggested above). The photo ship was a Piper Tri-Pacer with the rear passenger door removed, and me tethered to the seatbelt anchor with a climbing harness. Great fun! -Rob Prior
