    I've never heard of it here on the east coast.  I finally found 1 airport in NC with MOGAS, W17 (Raleigh East).  You just have to call ahead.
     
    I think I could just barely make it to W17, fill up and head on out to the coast for a fishing trip.  Just to be safe I would stop after I got out of the mountains and get a couple gallons of 100LL.  No need to cut it too close.
     
    From what I can tell all Non-Ethanol Fuel has been phased out it NC.  TN is another story, I find it everywhere in a 90 octane.  I did find a place to order Non-Ethanol 93 Octane in NC but it's an oil supply company and when myself and a buddy Frank went to go test it before we bought it had ethanol and water in it (alot).  Don't trust people who say it is ethanol free.

    Hi,
        have damaged Avid speed wing ,do you know where I can obtain a rib drawing from?
    Or replacment ribs.
    Thanks

    Hi
       have tried to contact Airdale for some replacment ribs,I'm located in the UK ,I will keep trying as your remarks advise.
    However a drawing of a Avid speed wing rib would be a great help at this time.Does any one know where to find one?
    Have tried to find but no joy as yet.
    Thanks.

    I bet if you wired that valve shut then the hacman kit would work! My understanding Is the valve opens, changing the intake pressure and preventing the hacman from leaning the mixture. Wire the valve shut and I would think the problem is solved.

    The valve doesn't move until the very last part of the power band like above 6500 rpm.

    He was doing a negative pushover. Typically not recommended by Rans, haha. I would say we have a very high number of the chaos's here in North Carolina. I have seen 5 or so in the last year. Neat airplanes.

    Why would one wire shut the rave valve? In all my talks with greensky and rotax Rick this has not been mentioned. Wouldn't it negate most of the power increase?

    Now that seems like a good match for a 670. WFO over the top of a runway doing aerobatics. I bet that would be a blast. It would be like flying a miniture Extra 300. If your looking at that guy check out the S-9 that has his ass saved by a BRS last summer when his wing departed the airplane!

    Thanks for the info - Probably too much engineering for me to change on mine - I will just stick to the KISS method, and use push-pull rods and bellcranks for everything. Guess if the Avid flaperons stay on, then my reinforced rib ends will be OK too.EDMO

    All cable operated. Pull-pull cables for the ailerons. Flaps are spring pressure up and cable-bellcrank-pushrod down.

    I don't know about the Super STOL. Probably the same. The slats are non controlled, just air pressure and balance.

    How many of you have heard of 100VLL, or used it? The first time I had heard of it was when I went to the site Doug posted above about Decalin.
    How much lead does this contain compared to 100LL which has 4 or 5 times the lead of the old 87?

    I ordered new capstrips and more 9460 today - will post a photo or two when I do my first "experimental modified rib".
    I am doing an old rib first before changing the ones on the wings.

    Chris,
    Thanks for the report with no BS - I only want to plug any leaks I might find - Not make tanks moonshine proof - You failed to say what "structural adhesive" you used - Would that be the Hysol 9460 that we are using to glue the ribs to the spars - and most everything else on my build?
    BTW: Amie is trying to get some nose-gear questions answered - She may want to contact you too.

    Ok, so I guess I coat my current tank with the VER and use av gas only in it, and put a 100ll only sticker on it. The new tank I am making out of the last a foam I will use the auto gas in. I really don't care about the difference in price. It is 90 miles to the nearest av gas and that is in the Las Vegas tca, not the most experimental friendly place on the planet. I always keep a drum of av gas in the hangar for the Cherokee when I am low but don't want to use it unless I have to. Burn half a day to fill the drum up so try to keep to a minimum. My engine builder asked me to keep my av gas burn to a minimum, said it increased maintenance schedule significantly.
    Just can't seem to catch a break. Oh well every shortcut I take has always been a mistake.

    The reason I do not believe it is a good idea to try and think in terms of ethanol proofing a non-ethanol proof tank is that ethanol will find a spot wher there is no coating and make its way between the coating and the fiberglass. No matter how good a job you do coating, there are still the tank penetrations where you probably cannot maintain the coating integerity. 
     
    I did a bunch of experiments with various coating compounds like Buna N rubber, polysulfide sealer, structural epoxy and phenolnovolac epoxy.
     
    I cut the holes in my tanks and used the cutouts to make test pieces. I first put a piece of the tank material in 10% ethanol. After a day or so the fiberglass surface softened. It didn't fall apart or anything, but with my fingernail I could put a dent in the glass. Once removed from the ethanol and left to sit for another couple of days, the fiberglass tank material hardened back up and remained seemed structurally sound. That was good news to me, but I knew deep insid that if the tank was continually exposed to ethanol, eventually it would deterioriate. 
     
    So I cut the fiberglass of my fuel tank material I had removed into a bunch of test pieces, sanded and cleaned them and put silver dollar sized coatings of each of the coating materials on each piece and exposed all of the samples to different fuels and additives. I tried all the different coatings in Avgas, 10% ethanol, non-ethanol regular autogas, seafoam fuel additive and Marvel mystery oil.
     
    All of the test samples survived the Avgas and Marvel mystery oil without any deterioriation of the coating or substrate tank material. All of the samples survived the regular autogas except the Buna N rubber which deterioriated in the ethanol and lost some color but did not deterioriate in the non ethanol gas and seafom. The structural epoxy, polysulfid sealer, and phenonovalac epoxy survived the everything including ethanol just fine, but the exposed fiberglass softened and the ethanol worked its way under all of the coatings and weakened the bond coating so I could easily peel it up as far as it had managed to work its way under the coating.
     
    So, there you have it. Those were real experiments I actually performed no BS speculation. Just the facts. If you are lucky enough to have vinylester tanks (or which ever resin is not ethanol sensitive), you are lucky indeed. If you have polyester (or what ever one is sensitive) like the tanks in my Magnum i do not think it is wise to try and coat them to make them ethanol proof. I reasoned it might last a long time, but no matter how I sliced it, it was time bomb. I ended up fixing the leaks with structural epoxy and never used ethanol. I think that is the only guarantee.
     
    I really liked the phenonovalac epoxy because it is impervious to almost anything, but it was very brittle. Bend it just a bit and it would snap. The structural epoxy was much more flexible when cured, and I only plugged the leaks, I did not coat the tanks. I would have used fiberglass resin if I had known which kind of resin my tanks were made of, but I didn't, and I did not want to take a chance with some incompatibility that I may not know about. The structural epoxy sticks like mad to everything, and I have no worries about it and have had no problems with my repairs.
     
    But I won't go near ethanol knowing what I know now.

    JUST HIGHLANDER CONTROLS?
    I have looked at photos, and videos, and still cannot tell how the Just Highlander attaches the flaps and ailerons, or how the controls are made and hooked up - Anyone got any info on that?
    Thanks,
    EDMO
    ADDED: This probably wont change my plans, since I am going to stay with the original avid mounts, and my modified controls for the flaps and ailerons - Just nosey...

    Awesome didn't know that. My local ia would argue with some of those points but whatever, I've modified this thing alot already.

    A Rans S9 Chaos is on barnstormers with a Rotax 670. Apparently it is a fairly famous airplane

    Depends on where you are - there are some states where real-gas is available in a lot of stations - But around St. Louis, you will have to look long and hard for it - Marinas and Farmers, I am told, may have it - but growing up on a farm and knowing a little about BIG boats - Most of them use diesel today. But, they still use gas for chainsaws!EDMO

    14 CFR 21.93 is pretty broad as far as a major mod. It includes things such as a different type of engine, new wings all together, ect. People rebuild their wrecked airplanes from the ground up and as long as it's basically the same plane that the Airworthiness cert was issued for originally it's totally legal. The biggie is the conditional inspection. As you probably already know if you are not the builder an A&P must sign it off. Doesn't even have to be an IA. Hope this helps.

    Good info. When I burn through my 50:1 Penzoil mix I will switch to the 100:1 if its really safe. 2-stroke oil is getting expensive.

    I wish more airports carried mogas but I understand why they don't. I was looking at 6a4's quote for 93 octane no ethanol mogas. The cheapest he could get it would be around $4.70 a gallon. Nobody would buy it. You could drive 5 minutes and get it for $3.70 at the local gas station and that stuff is ethanol free too
