    I had one landing last year at 9200', and had a pretty good pop/ backfire when I shutdown. A half hour later I fired it (Rotax) back up and all was normal so I gave it no further thought. I had E-10 that day, other landings at similar heights on pure gas, no backfire. No big deal, didn't seem to hurt anything.

Click on the winter newsletter for some interesting reading. Things just keep getting more efficient. One plant I'm in is just installing corn grinders that are used in the dogfood industry because they make the particles a more uniform size and even that is a big deal----the list goes on and on.

    Thats because all the ethanol refineries are 100% subsidized

    The only thing that could be construed as a subsidy is the Renewable Fuel Standard, saying to the oil companies "you will use X amount of biofuel per year". Lots of talk of doing away with that. NO SUBSIDY MONEY. But, oil companies LOVE making 84 octane gas. One of the ethanol plant guys told me that he thinks what oil companies really want is to own the ethanol plant too so they can get back to monopoly status. With the RFS, nobody said it had to be used as E10, it could be used as E30 or E85 and there wouldn't be enough ethanol to blend into the nation's gasoline----there'd be E0 everywhere. I've been using E30 to E50 in unmodified vehicles since 2001, vehicles as old as 1992 with no problems but officially that doesn't work. I've done some "firsts" with farming too and have heard, you can make it work but I know it wouldn't work for me.

    PS Glen, how many vents on the fuel system on you plane?????

    Marty it's the same plane we PMed about a few years ago. Only one vent in the cap, I know last time you told me to seal the vent when it's parked. That would take care of it when parked. But if you have looked at some of my pictures you know most of the time I'm not flying over that nice flat corn ground like you have in Iowa. And I also fly in the same terrain north of me when it's raining cats and dogs and 1400rpm ain't going to get me home. I'm still helping your corn fuel investment though, burn the ethanol gas just treat it first with Startron. I want my BTUs to be as waterproof as possible

    Just to limit the thread creep: there is an boundless thread on the relative merits of ethanol and its subsidies here: What About Ethanol?

    Gotta ask this question, by changing out the fuel line out to teflon down at gascolator, that solves that problem
    But on most of airplanes we are flying, what about the rubber lines where we come off the fuel
    Tanks, seems like unless you changed them as well , same thing will happen to them?

    Once installed, the cell is externally durable, internally impermeable, resistant to ozone damage and shrinkage and is compatible with all aviation and pump gas fuels, oils, and most corrosive fluids.
    I don't know about others, but my Cessna doesn't have any rubber lines between the bladders and the gascolator. I think Eagle uses nitrile rubber for their bladders.

    Gascolator is the worst one, most have a twist and a bend begging to collapse. Most of the other ones are just to join 2 tubes together.
