    I'm hoping that you might be able to pull it out and spread the wings and get a bunch of pics both overall and of little details.  There's an awful lot to be learned from a master just by looking at his work.

    Removing washout
    My Model 1 wings were built with a 2" block under the spar to set the washout as opposed to the 1 3/4" block called for in the plans.  I never flew it but was told it cruised at about 65 mph. This is about 10 mph slower than most of the cruise speeds i have heard for the early foxes with 65 hp and I suspect the increased washout plays a big role in that. 
    Just fyi the current model 7SS uses a half inch spacer.  I wonder how much faster the early foxes could be with that amount of washout? I've read a few posts on the subject but didn't  that see question answered.
    In any case I'm interested in cutting off the aft upper end of my lift strut and installing a rod end in the hopes of removing as much twist as possible. I've read a few posts on the subject.  I saw the caution about fuel tanks. I have 1 6 gal aluminum tank in the right wing so I know I can't go crazy. Do you think it's possible to get a full half inch out of it? Or will I be lucky to get even that extra 1/4" out?
    Any things that i need to be aware of if I go this route?

    About the only 4 stroke option i know of (needs lots of fabrication skills) is the Yamaha phazer.

    Make sure you educate yourself regarding rotax 2 strokes. The seals are only good for a certain number of years or hours, and like any engine if its been sitting for awhile could have some problems. If you have any questions about it better to have someone go through it who know what they're doing. 
    There are plenty of folks on this site who like 582's and plenty who don't. You have to educate yourself and decide for yourself. Like anything aviation related there are ways that they can bite you hard if you don't know what you're doing.

    From the pics I can see online it looks like the canopy is flat wrapped around a steel tube frame with a fiberglass "skull cap".  As long as you've got that steel frame you shouldn't have a problem. Just glue some foam blocks together and carve and sand it to get the cap, then fiberglass it and wrap the lexan sheet around the frame.

    Spot welding aluminum
    This came up on HBA and thought it was worth sharing here. Might be valuable for those who would otherwise have to rivet the trailing edge of a flaperon?
    For those who don't want to watch the video you can use a 220V steel spot welder to weld aluminum if you sandwich the 2 pieces of aluminum to be welded between 2 thin pieces of steel. The aluminum will be welded together but the steel will just pop off.

    Yeah I traded a little complexity in the mixer for simplified mounting and not having to reroute the rudder cables,  i also don't have to cut the control horns off the flaperons themselves. 
    Just alittle detail design left to do and order material. There's a lot of  parts that'll be laser cut and parts of the assembly are almost self jigging.

    New Flaperon Mixer system
    I'm wondering if I should be wearing my flame proof clothing for this but what the hey. 
    I designed a new flaperon mixer system that I'm about to start fabricating.  75% of it is copied from the later model Kitfoxes,  main differences being that the assembly is mounted to the tubes that divide the cockpit area from the tail cone and instead of having a single axel that has the control arms for both flaperons, Ive split that into right and left sides(red and green in the pic).
    Reasons for doing this are:
    1. Wanted differential in ailerons
    2. Free up area behind seat for some baggage
    3. No need to add additional structure to support mixer
    4. No need to re route rudder cables
    5. Loved the challenge of designing it.
    Cons:
    1. More complex mechanically(but not more than the old system).
    2. Need to disconnect pushrods top fold wings. 
    In the pic the purple portion is the flap mechanism and works just like the kitfox system. The blue portion reverses the direction so so the green and red move differentially. 
    If it's not clear I'll show pics when it's built

    I find that if I crop a picture very slightly that it will load. Kind of a pain but I hope you'll consider taking the time to try it. You're project looks really cool.
    I like the way you covered the cabane. Ive been thinking of ways to streamline mine as well. Might have to copy that idea.

    It was the "duchebag" comment I thought was over the top.  If you think the guy was overdoing it with the hype you were at least respectful expressing your opinion about it,  blunt but respectful.  
    Why do I get worked up over situations like this? I just happen to believe common courtesy and just plain being nice to others  is important. Although common courtesy isn't very common anymore. If you're nice to others who will never meet you then you're more likely to be nice to those around you.  I guess I'm probably just out of touch with reality. Stepping off the soap box.

    It might well be that he got himself into trouble in the type of stall that he was demonstrating at the end of the video. Obviously the aircraft is now in a safe configuration but maybe he was thinking back to the incipient spin mentioned at the beginning of the video.
    In any case giving people the benefit of the doubt goes a long way.  He was willing to share his experiences fitting vg's to his aircraft and there's valuable info in the video that benefits us. A few comments like the ones above and maybe he decideds not to post anymore videos.
