I was set up to go donw and wathc a 360 put back today or wed, but no one returned 2 calls yesterday so now having 2nd thoughts. I am looking at upgrade to 160 hp even tho I will loose Mogas ability. I took Tweetybird into a grass strip Sat and when coming out I was looking at a very high hill covered with trees a lot closser than I had intended. (Im 150 hp).

Reportedly NONE. I called a medical supply place and they wanted $18 for a refill plus I needed a prescription since O2 is a "drug."

In practice, I've actually been in the facility where our hospital, airport, and welders fill their O2 locally at a gas supplier....and they all come off the same tap. Done numerous hundreds of deep dives using commercial helium, and done hundreds of hours of decompression using welding O2. For welding, they require purity. Argon may have some differences, but since I just used that to fill my suit I didn't care. Concidently, I'm taking my O2 bottle in this afternoon to our local welding/medical/aviation gas supplier to have it filled. Tim Olson - RV-10 N104CD - Flying do not archive Konrad L.

Oh, yeah. Let's not forget the normally aspirated O540s, either. I think those are the 235 hp versions for you -10 builders? H2ADs and fuel injected O360s were not approved. I think it applies to any fuel injected engine, actually. Of course, he noted that fuel line sizes, routing, and other variables, could impact the use of auto gas due to vapor lock. He also mentioned that some materials in our tanks may not hold up to the rigors of auto gas. The engines were OK, though. To run the higher compression engines on auto gas, just bump up to 91-93 antiknock gas. I invested in my first auto gas STC in 1986 and have saved money on gas for my airplanes, since. My RV-6A has a 150hp O320 that runs well on 87 antiknock. The tanks and fuel system have shown no adverse effects of having auto fuel in them, other than the minor vapor locking that can happen during fast turnarounds. The plugs are clean, except for some carbon build up. Oil, not fuel. No lead to foul plugs. Per Petersen's STC, I do put in some 100LL a couple of times a year. I can always tell the difference. Within an hour, or so, the lead deposits start building up and fouling plugs. Vapor locking is a minor problem, as was the case in my other two airplanes. If in doubt, I add some 100LL to the mix to change the vapor pressure so that the fuel is less apt to vapor lock. About the only time I chose to do this is if I'm going to take up a lot of kids during a Young Eagles day. If it's cold outside, I don't bother. If I ever get around to finishing my -7A, it will have an O320 160hp engine or an O360 180hp engine. Since I already have some pieces and parts for the O320, that will probably be my choice. I plan on using premium unleaded in it. I can't afford to own an airplane and keep it filled with 100LL. I'm just getting used to putting premium in my new Miata!

As I understand the situation (and I am certainly willing to be corrected!) the mere act of bolting a certificated engine to an experimental airframe does not cause the engine to lose its certificated status. However, if the engine was to be returned to service on a certificated airframe, the installation would have to be signed off by an AI. And.....how many AI's are going to put their career on the line by signing off on an engine that they are not *absolutely certain* meets all certification requirements. The AI covering his backside is why the engine will most likely be torn down to insure compliance, not just the fact that it was bolted to an experimental airframe. If you can find an AI that is willing to sign off the engine installation without a teardown, it will be legal.

I recall emails from our friendly FAA guy that stated that the FAA considered all appliances when attached to an experimental airframe to be experimental. If your engine logs state that your engine was installed on an RV, Glasair, or any other experimental airframe followed by your signature, I don't know of any AP/IA that would sign if off for a reinstall on a certified aircraft. The local FSDO would be sure to frown on it. It's a real grey area. This might be a good question to kick up to the EAA experts.

After experimenting with several different things, I found that a (baby size) router used for laminate trimming worked the best for me. I made a wooden jig for the two rectangular holes needed for the EFIS and AOA mounting and the results turned out very nice, almost as good a as a CNC milling machine. Round instrument holes were cut with the common fly cutter and came out nice as well, I just had to adjust the damn thing for each my 2.5 inch instruments as they didn't seem to be a common size! I solved my problem of the funny VM1000 engine monitor display cutout by sending my blank to Mr Steve Davis of Memphis Tennessee (phone number 901-240-3068). Steve has autocad AND machining facilities and has done some very nice work on RV panels. He did a very nice job on my cutout and the price was VERY reasonable, it saved me a lot of work and disappointment. I highly recommend letting Steve do your panel if you have the resources. I've spent the better part of the last month (spare time) doing the flight instrument side of the panel and it was a lot more work than I expected (I have lots of stuff in there though). I enjoyed doing it but could be further along towards clearing the prop if I'd let someone else do that part of it.
