    When I was learning tailwheel, I had several groundloop experiences first traced to a faulty tailwheel lock, a blown tire, and finally a quartering tailwind. In each case, I tried to counter the initiation of the groundloop with increasingly hard rudder, and in each case, as I increased rudder pressure, the swing intensified instead of correcting. Being kind of slow, and the fact that the ground loops happened pretty fast, it took until the third time to understand that the brake pedal design was partly, if not largely to blame. The flaw of the design is that as one pedal is pushed, the opposite brake pedal is potentially pushed into the opposite foot, causing braking in the opposite direction from the control input. As aerodynamic control decreases, the potential for cross control from the inadvertent braking is increased. To eliminate this potential, the cylinder must be mounted to the floor instead of the cross tube, and the cross tubes have to be raised about 1/2 inch with spacers. The pictures show how the brake pedal moves out of the way of the opposing foot when hard rudder input is given. An additional benefit is that as slight brake input is automatic with full rudder input. To get the correct pedal position, some "experimental" wooden dowel was used. The next generation of the pedal will be built for proper pedal position. With this setup, I have been able to consistently land on pavement without any problem..... and I always check the tail wheel lock!!

    I sent it in August 2011. Look at the bottom of page 89 for instructions. Russ.

    Russ, Just wanted to add my Congrats. I just posted a note about learning the Stewart sysltem. I think it is the best thing since Ray Stits got dacron approved to replace cotton.

    Ed glad you like the site!! If we could only convince all the knowledgeable guys on the Yahoo list to come over and give it a whirl!

    YES - Knowledge is what we all want. People with money don't have to ask for it - they just buy it or rent it!

    I feel like I have done well to design mine using Dean's basic airframe and wings, but am at the point where I could sure use some engineering help on the nosegear design. I have nightmares of it collapsing and the nose digging a hole in the runway which I will have to fix!

    I know that it is much easier to build from a kit, but I am just stubborn enough to build what I want, and not someone else's plane, even tho I can only lay claim to about half of my design. But then, everyone, even the Giants in aircraft manufacturing, has "borrowed" from an earlier designer in some way.

    This has been a 16 year struggle, but so many other things have interfered. Finally, I am trying to get it finished before I get unable (you never get "too old") to fly.

    For anyone interested, I measured my Homemade Lexan TD for Doug. I will have to compare his measurements to mine.

    At the front: 32 3/4 inches wide inside the turn-down.

    At the Rear: 26 1/2 inches " " " "

    Length: 30 3/4

    Turned down sides: 4 3/4 going back 17 1/4 and tapering from there to 3/4 at the rear.

    Thanks for writing about your near miss. By sharing, You're helping others who might find themselves in a similar situation. I'm sure it's a lesson that will be remembered by all involved and will help you all be safer.

    Don't let something like that keep you on the ground though. Your experience will be valuable in keeping future events safer.

    Hang in there!

    We all are aware that Avids and to a greater extent Kitfoxes suffer from limited visibility when on the ground in their three point stance. I had a close call today that I want to share in hopes that people will learn from it.

    I went to a ski plane fly-in on a lake frequented by snowmobiles and ice fishermen. The arrival and socialization at the event were without incident and quite fun. The departure was a little different.

    Three of the remaining six planes there were going to depart, I was one of them. We all started and were warming up. I decided to take lead and pulled forward. The guy putting on the event had a hand held radio and was acting as a lookout for sleds and people on the ice. As I pulled forward toward my intended takeoff area, I told him my intention was to cross to the far side of a row of barrels (marking the snowmobile trail) and depart. He acknowledged this transmission by telling me that the far side of the trail was much smoother. I was concerned with hitting one of the barrels so I was watching it pass out the left side windscreen/door. I passed the barrel, turned to the right, up the trail and added power to take off. As I was accelerating, I saw a flash on my right side. I later learned that this flash was the guy with the radio diving out of the way of my plane.

    While maneuvering on the ground (ice) I never saw him. I assumed he was clear. My fault.

    While maneuvering on the ground (ice) he never told me his position or that I was taxiing directly toward him. He assumed I saw him. His fault.

    I didn't learn of the seriousness of this incident until I spoke with him on the phone later, after I arrived home, needless to say he was still quite upset. (His wife even more so.) He is okay, but bruised and shaken from our close call. He said he never saw me approaching because he was watching a passing snowmobile to be sure it was clear. He only dove aside when he heard me throttle up. I will not take argument against him, but I think this is a pretty weak excuse on his part. I would never take my eyes off a nearby running airplane, especially one approaching me. Which is definitely not to say I am without fault in this incident. He said I should have been 's' turning. Anyone who has flown on skis knows this really isn't a possibility and he acknowledged that in our later conversation.

    As I write this, I am torn inside. I don't think this will curb my flying, but it was a near catastrophe that will haunt me, probably for ever. And rightly so.

    Some of you may/would laugh this off. I can't. In spite of this happening I consider(-ed?) myself to be fairly cautious and safe in my airplane operations. Now I'm questioning that.

    I hope anyone reading this can learn from this instance.

    I need to attach a extension to the rudder pedal because I can not tip my brake pedal forward far enough. I don't have the extended firewall with my 503 so I lose about 3" of leg room, which brings my feet closer to the seat. When that happens just the toes of my boots are resting on the rudder peddals and the brakes. I might try to grind part of the toe bracket off so I can tip the peddals forward more.

    I'm in the same situation just North of Chicago. I decided to ferry no-Ethanol gas from Wisconsin by car and use relatively close airports with Mogas if going by air. You might find a similar solution would work for you in MO. Here a couple of helpful links to help you find your gold:

    Paul, That Pure-Gas site looked like a Goldmine to me! Many Thanks for the info. Those towns are on my flight list.

    I thot pure gas had gone the way of the dinosauers.

    Great info - now I can relax until our Govmt acts again. I started designing and building this "Foxy Flapper" airplane years ago in Alaska, and was not worried about alcohol in my gas there.

    I think that is why Mikesk's pedals have the cross bar that your feet rest on so you stay off the brakes till your really ready to apply them. You may be able to modify your new pedals with minimal welding to mirror something like his.

    A pic of what you have from Brett would help us see what you are dealing with.

    Hey Leni,

    Are you planning to fly out for the Iron Dog this year? Let me know. Looks like a good one today; got to go make tracks in the foot of fresh snow tongue.gif

    I would like to fly out for the ID this year for sure!

    My brother is flying up to the lodge today to take my cousin in to get his 3 sleds that they left up there. I am still at work till the 7th.

    Thanks again for giving Jen a ride back to Biglake, that was AWESOME timing! She enjoyed the flight very much!

    I saw that one too. Looks like an A model to me based on the wheels. That 532 is probably 20 years old, single points ignition, and basically a boat anchor. Considering you can buy a flying B model with a 582 for 10-12K I'd say this isn't a very good deal. My Dad sold a covered C model ready for paint with a 532 for 4500 and he made money on the deal for what he paid for it.

    Found this this morning....may be a good deal? Wish I were closer to look it over...but would probably buy it and get C box on that engine.

    There is a few people claiming to "wash" the ethanol out of contaminated gasoline.

    Theory: This is being done by pouring water into the fuel to combine with the ethanol. This mixture then falls out of suspension, leaving 'clean' fuel to be skimmed off.

    Maybe I'd use this 'fuel' in my lawnmower, but certainly not in my airplane. (At least not with me flying in it...)

    Someone probably has gone here before - yes, I have read about the plastic tanks. Want to hear about my bank account & bills? (Didn't think so!)

    The stories I have heard about fiberglas tanks and ethenol have me worried.

    Years ago, a friend in Alaska landed his Kitfox in a tree. He said that the good thing about glas tanks was that they disintergrate on contact with a tree, and the gas dispersed quickly in a cloud of vapor, and no fire!

    I have FOUR - 12 gal fiberglas tanks that are installed and were built by Ron's Fiberglas when he was the supplier for Kitfox. That was before our Govment in its wisdom starting putting 10% moonshine alcohol in our Mogas.

    If they can put it in, then IMO, some chemical engineer can figure out how to get it out: anyone know one?

    Thought about pissing in a can of it, but Budweiser has 5% alcohol in it, so would only cut it in half.

    Is there a way to get TCP now, so I could run 100LL? They banned shipments of it once.

    Many-Many years ago, Shell was starting to advertise TCP in their gas. Also, to "Put a Tiger in your Tank". I was at a gas station in Arkansas, and asked the boy working there if he knew what TCP stood for. He shook his head, spit some tobacco juice on the ground, and said, "Best I can guess, it must be TOM-CAT PISS!

    Ed -

    I put pics and measurements of my Avid+ turtledeck a bit earlier in this thread. Can you compare these to the smoked Lexan turtledeck you have please, would be interested if it fits. Thanks.



    Go back to my alzheimers statement: Mine is clear, not smoked!

    Sorry for the misunderstanding. I will look at your measurements anyway, and they may be helpful and comparable.

    I will post the comparisons.

    Thanks, Ed in MO

    Russ your airplane is in this months Sport Aviation mag. How did you submit it and how long ago was is?

    I sent it in August 2011. Look at the bottom of page 89 for instructions. Russ.
