I laid it up on the canopy/canopy frame after covering it with a layer of plastic saran wrap. After it sets up, pop it loose. Sand and finish it, paint it, drill it and attach with screws. I also used some Lexel sparingly. Works great after 100+ hours of flight. No chance of accidentally sanding into your canopy like with other fiberglass attachments. Only down side is it takes about a week or so to get a perfect finished product. If I was good with metal I might of tried that method. However, fiber glass is a great way to get a real quality finish. I am working on a targa strip now using the same method.

I have used the cork screw type but out of mild steel. They are hell to screw into hard rocky gound. They constantly break when you try to install them in hard or rocky ground. As tough as Ti, it will bend and twist when you try to torque the triangle head with a lever or stick. The cross section is a rather small rod. Also poorly designed is the top triangle loop, which is not welded. It may save weight and be Good enough, it does no good if you can't get it into the ground. Most of use will not carry our tie downs with us except for the long X-C and airshows. Lose 8 lbs off you a** and that will cover the extra weight of the claw, which should be way easier to install and remove in all conditions. George M.

Where should I >direct the blast tubes for the Mag and P-Mag? The alt, the 35 amp one Van sells is an old NipponDenso alternator for a early 80's Honda. I agree towards the back at the diodes. Consider a little metal shield on the #1 exhaust pipe held on with hose clamps and standoffs. The KEY to not heating that small alternator is keep the battery in good shape, make sure the engine is tuned for easy starting and let the engine run (and battery charge) for a little bit (10-15 seconds) before slamming on all the electric's on. While you are waiting you can adjust the idle and mixture, clear the area and check the engine gauges. The reason I say this is your alternator is only 35 amps. You don't want to load the alternator more than 60-70% continuous. So 35 x 0.60 is 21.0 amps. A drained battery right after start can pull 10 amps or more. Throw on all your radios and lights right after start you might exceed this arbitrary drain and over heat the alternator, which will reduce its life. The key is keep the alternator load down on the ground when airflow is low. For some reason Van's sells these alternators with out the stock cooling fan, may be save weight and engine drag (lost HP). Just because it is rated at 35amps does not mean it can output that without eventually melting. Plus with the hot exhaust nearby and the stock fan removed you have a good chance of cutting the life down real short if you don't observe some load limits, especially on the ground. For the mag consider removing the inspection plug and blowing it right in the housing**. Of course you will want some kind of filter and screen. An alternative is just at the side of the mag to promote general cooler airflow for the hottest part, the coils. **Speed w/ Economy by Kent Paser The P-mags? I have no idea, but near the coil or electronics, spacifically transitiors. George M. RV-4/RV-7 --------------------------------- Yahoo! Groups gets better. Check out the new email design.

Question for any of you who may be "in the know" on metal sources though.... Do you think that titanium stakes for use in the claw would save a bit of weight? It comes with 9 steel stakes, and it adds up a bit. If I could spend $50 extra and get titanium, I may consider it.

Hence the use of impact type drivers. That's also the reason one puts chain on an anchor. The chain takes up the "yank" of the boat so that the anchor has a constant pull as well as changing the pull vector which tends to dig it in rather than pull it out. The same is true for properly securing a boat, you always put a spring line in during heavy WX because that yanking will tear the lines and or rip the cleats out of the doc. A good spring will cause the boat to rotate and wobble rather than snap at the end of its yank. If your wings can lift 2500 lbs at 48 kts and yank and tug with however dang much that momentum energy is (far more than an engine hoist hanging static) and periphrial winds around a tornado easily exceed 100 kts as far as several hundreds of yards away my feeling is that I want more than a titanium curley fry stuck in the ground... truth is, I carry both, when WX comes into OSH I throw it all into the ground. And then I pray. ;{) and please do not archive this While I'm sure the claw works great, I don't think the kind of loads that these tie downs see aren't anywhere close to what an engine hoist would pull. The loads are going to be brief jerking when gusts of winds might hit the airplane. An engine hoist is going to progressively pull harder and consistently. I've seen these tie downs hold down some buckling airplanes with no problem. Plus, they screw into just about anything without bending or breaking.

Charlie, yeah, basically the old tractor carbs suck, but they don't suck for long enough.... ;{) I've been thinking about it and looking for years but everything I come up with that might do it has the potential to fail sending bad things into the engine. But a whizzing chopper fan that fits up into the sump would do it. A few of the older radials do this. The gear driven impeller really wasn't for boosting it's just for mixing and evenly distributing. But one would really want a strong screen around it.... do not archive ________________________________ Message 10 ____________________________________ Time: 09:42:47 AM PST US From: George Inman 204 287 8334 Subject: RV-List: accessing Nav antena RV6a --> RV-List message posted by: George Inman 204 287 8334 I have an RV-8 ,and use the following method to crawl into the tail cone. Place several pillows on bottom of the tail cone between the bulkheads Place long piece/pieces of plywood on top of pillows Crawl on top of plywood. I weigh about 160lbs,so if you weigh a lot more get someone smaller to do it. I found out that my nav antena under the tail end of fusl is on the fritz, balun conn is suspect. I didnt build the plane so assume it was mounted durring build. How to access it? Can one crawl back far enough to reach it? or cut an access hole? (if so is that a good idea as the place would be put over the hole without indentations like other acess hole have) Charlie Heathco -- George H.

It looked like a thin surfboard with notches cut in the sides to match the bulk heads. It was cut so the surfboard rested only on the flat areas of the bulk heads.We has several couch pillows that we placed between each of the bulkheads. We made the "surfboard" before putting the top skin in place. I weight in at 240# but had the looong arms required to reach the far end. Ran the light cord out thru the rear inspection hole (tube type to reduce heat) & put a fan between my feet. We have reused it several times, rotate it to install or remove. On HRII we would have to pull the elevator tube to use it now. Things I would have done different: Sand & paint (white) the surf board, especially the edges. Lots of splinters when sliding in and/or out.

I checked my index of RV-ators which covers a 4 or 5 year period before 2004 and didn't spot it. It's not in the 21 years of the RV-ator book either which ends at 2000. I think it was some time between 2000 and 2004 even though I didn't spot it. Ken at van's has talked to me about it - in fact I think he suggested it to me. He may be able to point you to the right issue. I'll let you know if I find it.
