Hi Darrin again.. one more suggestion.. If you are an AOPA member you have access to a free medical advise service to help in just such cases as your's . You call the main number and give your AOPA member number and ask for the advisor for medicals. They will give you every different scienario with your condition and tell you what you need to know about a "self certified physical". I have a diabetec pilot friend that has to use the computer insulin pump 24 hours a day but flys sailplanes. He has looked into the higher performance motorgliders and there is a hitch with increased performance or horsepower, but I don't remember which. I bet AOPA can help you tho.

No. The feet are firmly planted. I don't think they would help any. The Revmaster book of words recommends checking them now and then just to be sure of the .006 gap. When I looked yesterday before re-aligning them, one exhaust lifter was spaced enough to put a screwdrive through it, and the intake on the other jug was just about as bad. That explained the "0" compression reading that I got. The intake on the first one had no gap at all, as did the exhaust on the other. Ever hear a Volks "Bug" going by?

Know what rocker arms are and rocker shafts are, rocker shaft spring washers, valve springs, valve spring shims, valve spring retainers and rocker arm adjusters. On my engines that I built from scratch the rocker arms as per the locking springs. The valve springs were matched for the same pressure and shimmed for the same valve opening pressure of the valves. I used the swivel adjusters which seem to work very well. Tappet settings were .005 for intake and .007 for exhaust, reset/checked every 25 hours when I did an oil change, .006 is good too. We used this in VW cars. This is the suggestion taken from Rex Taylor. All the valves were hand lapped after the initial grind and tappet setting were checked 5, 10, and 15 hours after initial assembly or until I felt that they had seated in. The only thing I found is occasionally the rocker shaft spring washers would break and needed replacing this happened to me about 3 different times. These are the springs washers that are placed on each side of the rocker arms on the rocker shaft. Gave the hydraulic lifters some thought but felt that it could be just another thing that can go wrong. I like simplicity and the KISS principle. The valve train on the VW is the weakest point on the engine and should have frequent attention. Only my two cents worth, hope it helps. - -- Adrian VE6AFY Mailto:cartera@cuug.ab.ca http://www.cuug.ab.ca/~cartera ------------------------------ Date: Tue, 21 Jul 1998 13:43:43 -0700 From: Micheal Mims Subject: Re: KR: Revmaster Vs.

Questions have been raised as to whether or not this aligns with top of top longeron, center of top longeron, bottom of top longeron, or long of middle bottomeron; you decide based on your bird and engine ;o) The usual fine print applies, since I measured it up using a standard 12 ft. St*nley measuring tape and Model A-1 eyeballs. Use at your own risk; results may vary; no guarantees as to accuracy. If you build something to my little drawing, you risk disappointment!

You could also have used a lens (50mm or higher) from far enough away to get good plan view photo's of the cowling's exact front, side, top, bottom , etc. Then scanned them in and use them as a profile guide for the model, scaling it to the measurements you took. One could do the picture method with their boat from the same angles, and then make their own model in the computer to see what cowling profile will best match things. Comparing with the one you made would give the area's that need work or adjustment. A fairly good distance is needed so the perspective distortion is minimized for any photo's taken.

There is a traveling newsletter archive going around, but don't know where it is at the moment. You will also find some methods for boating that you may find helpful. Some have found it helpful to use full size cross section templates of plywood or partical board at appropriate points to keep the boat symmetrical and form guides for joining it all together.

He has a high compression setup to squeeze 44 HP out of that 1/2 VW. They have run into two chronic problems with the engine and the 100LL. 1) He has to grind or replace valves every 50 - 70 hours. A regular top end tear down is part of normal maintenance. 2) He has also had a chronic problem with the lead deposits building up above the top ring between the piston and wall causing scoring of the cylinder wall. This was fixed by cutting down the diameter of the piston just above he upper ring. That's the trade-off of using a VW. The top end requires some TLC to keep it running properly, but the parts are dirt cheap as compared to my C-85 and easily replaced.. As for 100LL in the C-85, mine has had a steady diet of 100LL for the last 400 hours with no evident problems. The last 112 hours in the last year in my KR. I don't use any additives, but have used Marvel's Mystery Oil to successfully free up sticky valves in other engines.

As soon as I get them I will pass them along to Mark Langford so that we can get them scanned. Should be able to get .DXF files to add to your engine and cowling library. I still need to find drawings of the BMW R1100 motorcycle engine that I plan to use. Anyone know where I can get drawings?

Steve If someone was going to follow Mike Mimms' idea and rig up a belt drive to run one of these on the side of the engine, it would seem just as easy to do it with a Slick, and a hell of a lot cheaper.

On the other hand, a person who knew he had a serious disease could not honestly say that. I think it would depend on why you're in danger of losing your medical. Diabetes, cancer, AIDS, etc., that's stable and under control is one thing, but if you might have a coronary any minute, it would be irresponsible to be a PIC unless you never fly over populated areas and have no loved ones.

One thing I had to make absolutely sure of was to lean the heck out of it (even while taxiing) and run them hard. Students used to foul the heck out of plugs because they would not lean during idle and taxi. Both the VWs in the hanger eat 100LL on a regular basis and work fine (well if tearing the heads off every 200 hours is fine) and both are leaned during all modes of operation. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..

Unfortunately most of the guys I have run into lately are fine medically. One case is the KR builder/flyer at my airport who now has a artificial heart valve (original was defective since childhood) and is waiting for what seems like 215 Dr's to sign wavers. Heck the Dr. who installed the valve told the FAA that he is in much better shape now than when he had a valid medical but they (the FAA) didn't care. The builder continues to wait it out and who knows what the outcome will be. Another guy decided to honestly answer the medical questionnaire by saying his Dr. had given him a prescription for slightly higher than normal blood pressure. Guess what? No more medical! He has lost 15 pounds since and no longer takes the drug but still no medical. If you can help it do not get caught up the web of bureaucracy the FAA spins! It really sucks! zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..
