    Update: flew an hour this evening and I’m happy to report the plane flys like it’s supposed too. Roll rate is back and the plane feels solid. I set the Ailerons reflexed 2 degrees. I can’t believe how bad it was before. I leaned out the idler circuit, adjusted the needles and timed the slides. Temp were great. Still would like to see more RPM on take off. The new prop is supposed to be here tomorrow. Hope to get this thing dialed in this weekend.

    i guess the only benefit of going away from wood is rotting issues. i suppose a carbon spar and ribs would be lighter, but likely juice not worth the squeeze. just interesting thinking i suppose.

    Back when I was flying a Himax, I was talking to Wayne Ison who was the designer of the Mini Max, Himax, Airbike, and a couple of the Fisher aircraft.  He was telling me about how Hummul Aviation copied the mini max but did it out of aluminum, (at least the wings for sure) and it came in heavier than the wood built Mini max wing.  The wood was also easier to work with, and cheaper to build.  Hard to beat the design that Dean Wilson came up with, with the aluminum spars and wood ribs, probably for either cost, weight, or ease of building.  And as far as strength goes, Kitfox has run the same design with a better stiffener up to 1550 gross weight with no problems.

    THANKS TO ALL OF AFF, Jim, Doug, and others who have shared concerns.  You make me feel better having you as an extended, caring, family.  I am weak, but they tell me that a recovery day is coming someday.  I have more tests in November and I will try to give you some info by December.  Too shaky to type.  E-CARD IS A NICE GESTURE, but your posts are enough, really Thanking all of you.  Stay tuned, ;<)  edmo

    Not so sure they are, in any event I never weighed any of my wings.

    News about Ed (EDMO)
    Hi all, just got off the phone with Ed, he has been going through a rather tough time with cancer.  He has been on radiation treatments and he told me today that 3 of the 4 spots had gone away, and now they were doing more radiation on the last spot.  Seems that it has left him very weak though, and he said he had lost 40 lbs of muscle.  He was happy that we were concerned about him, and asked that I let you all know this.  He said he hasn't been on the computer for a couple of weeks, and his brain is pretty foggy.  He did sound real good, and coherent, so that was very nice.  Hopefully he can rejoin our group soon.  It would be nice if we could somehow make a get well card for him with everyone signing it that wanted to.  I know it would brighten his day.  Not sure how that can be done with a computer though.  I could print it and snail mail it to him if someone could figure out how to do it.  Maybe just a message thread that everyone quotes the previous poster, and then I print the last one after a week or so.  Then everyone go back and delete their original post?  Suggestions welcome!  JImChuk

    Sonex Tail dragger
    Hi guys
    I've been looking at a new project aircraft and I'm thinking about the sonex Tail dragger with the aerovee and as there are only a handful of them flying in the UK and I wanted to see what you guys think of them ?

  15. dav8or added a post in a topic Nylaflow Poly-flow fittings problems   

    I cut and re-welded the master cylinder mounting tabs on the pedals to get better leverage and I can now hold the plane at 4500rpm without creeping. I think it will get better as the pads bed in on the rotors. I am happy to have brakes that work finally.

  16. dav8or added a post in a topic Wingtip damage repair   

    I got a couple more pictures. Weather has not given me a break here to get anything out of the hangar so I pulled forward as much as I could.
    I am going to try a small iron one more time before I start cutting. I am also going to set a 4' or 6' level across the tails of the ribs on both wings to compare and determine if it is bent upwards because it is still pretty hard to tell.
    i also happen to have a pair of Kitfox fiberglass droop tips. I wonder how that would affect the performance of my Avid Speedwing. They look like they would fit although it would reduce span by a few inches.

    Global Warming Hype
    I don't know if you realize but the current trend in California to do away with all fossil fuels by 2045 will completely destroy private aviation.  This will spread across the U.S.  There is no way to produce an electric plane that has enough batteries to power it for 2 hours and light enough to haul two people and cargo unless of course you build it with balsa wood and fly only on zero wind days.  If we continue to follow U.N. trends the U.S. will be completely annihilated along with all the vehicles.  The state of California is following the false science of the U.N. that claims CO2 is causing global warming.  CO2 makes up .0004 percent of the atmosphere along with hundreds of other naturally occurring gases.  Climate change is happening but climate change has always happened.  They are suggesting that glaciers are melting because of CO2.  This is false as well.  Underneath the Swiss Alps glaciers are entire forests.  Underneath the Mendenhall glacier in Alaska are trees with roots still in the ground.  This means the glaciers were not there in the past when cars did not even exist.  Also trees need CO2 to survive.  .0004 percent of CO2 is very low and it was much higher in the past before the industrialized revolution.  Dozens of U.N. scientists have quit because they see the falsehood of the science that is purely a political agenda to suck the U.S. into a new world order.  The only way to stop this progressive movement is at the ballot box.  The U.N. has ingeniously integrated immigration and climate change into the left philosophy to secure their path forward.  If you don't stop it at the ballot box we will wake up one day and private aviation will be over. That is not far fetched.  Most of the population could care less because they don't have a plane but our vote does count.
    So the main point of all my rhetoric is to suggest that many voters in our country are out of balance with false information.  We need to bring balance back to our states at the ballot box.  Remember that November is a referendum against Trump.  He may be an idiot speaker but His policies are pro freedom and Anti-globalists.

    Looks like a piece of metal filled in with white silicone? Can you provide any details? How did you mount it?
    I have a friend that works magic small fiberglass molds. I'm thinking I could have him help me make molds of these. Attach with two sided tape??

    Flap travel
    After adjusting the flaperons I decided to check throw of the flap system. The stop bolt that was installed between the seats had them set at about 11 degrees of deflection. I installed a shorter bolt and was able to get 13.2. The book says to set them at 15 or less. I looked over the linkage and it does not look like there is adjustment for anymore length throw. Any Idea.
    Any Ideas?

  22. nlappos added a post in a topic New Rotax 670 Install   

    the 670 has 670 CC's, like the 582 has 582. That's the trick. The larger pistons and stroke of the 670 buy you the extra HP. The engine has been widely used in snowmobiles for decades. For aircraft use, the 670 gives 92 Horsepower at 6350 rpm, vice the 65 HP at 6500 for the 582 blue head.
    The 670 weighs about 10 lb more (all inclusive) than the 582.
    From the Rotax specs:
    582 bore 76 mm, stroke 64 mm
    670 bore 78 mm, stroke 70 mm
    Here is Rotax Rick's specs page:
    The 670 has "RAVE" valves that retune the exhaust with rpm, so the gas mileage stays low across a wider rpm range. These valves also add power, because they keep the exhaust properly tuned.

    What is the HP of the 670 and what did Rotax do to get the increase? Larger pistons? Different stroke? Higher RPM?

    Jabiru Engines
    I think I have posted about this before, but it needs repeating.
    I have pulled the heads on my Jabiru 2200 several times and each time I have had this problem.
    The hydraulic lifters on the pulled head do not relax after reinstalling the head.
    This causes the valves, sometime only one, but many times both to be partially opened.
    You will be able to see this by comparing the position of the valves on the head you didn't work on. They will not be as far out and near the edge of the rocker box edge as the untouched head. 
    So when you turn the prop by hand you will find one cylinder with no compression. If the intake valve is held open too, you may see one of the other cylinders with no compression because of lack of vacuum.
    If this happens you have a couple choices:
    A) remove the head again and pull the lifters and soak them to get all the oil out. You should be able to compress them when they are clean.
    B) Start the engine and let it run roughly until the oil temperature builds. This can take 5-10 minutes. You should see the EGT start to build on the soft cylinder and then after the oil is heat soaked the hyd lifters will relax and the engine will smooth out.
    Flew it for an hour for check out. All is well now.

    I am getting 550-600 fpm at 6000 feet and 95 degrees, with about 950 lbs GW. That is a bit more than I got at sea level with the 582, with the same aircraft. That checks out, since I am now at about 9000 DA, so the 670 is putting out the same horsepower at this altitude that the 582 did at sea level. See above, I posted fuel flows as well.
