    Elevator resistance
    The last flight I noticed that when I did my elevator check if I let it down slowly with my hand is seems normal (no resistance). If I pull the stick back and let it go it lets down slowly like the elevator control rod is pushing against the controls. I plan to take the elevator control rod loss from the controls down between the seats and see if the resistance is there without it hooked to the controls. I see some movement in one of the blocks that hold the main control tube to the floor board. I'm wondering if one of the blocks is loose enough that its causing a bind from side to side once weight is applied to it from the elevator control rod. I may need to pull the belly pan off and tighten the bolt that hole the block to the floor and apply some lube. 
    Has anyone else had the same thing happen?

    Here is the Rotax page for downloading everything. It is also freshened by Rotax, of course:

    Looking good mr.  Can't wait to get back up there and play again!!  Next time we will do a lot more flying.  I can play in the dirt at night with lights if I have to 
    Keep at it and you will have a fleet of em to fly soon!

    As an observation for my Mk IV, there is no friction as such. On the ground the stick feels heavy due to the weight of the elevator, but the motion is free and not at all sticky. I suspect any friction will come from some rod or crank rubbing in the area just aft of the stick, under the seat and into the mixer behind the seat. I would look hard to find it just to be sure.

    Is it a friction in the links or do you think it is the push-pull rod that creat the friction, maybe it is bent?

    You will always have a small amount of friction plus if the elevator is connected, you'll feel the weight of that also. Hard to figure what you call friction, but none the less, you shouldn't have an excessive amount in any control.

    Well got the elevator all covered and ready to put backon.  Going to pickup some flatstock now and make a solid mount for bottom of windsheild so will have support, i really like the cowl comin off from prop to windsheild, my Blackfox doesnt do that.

    The tubing repair video JimChuck posted is very much worth the time to view it. It does talk about a new wonder material called 'asbestos', however! Just use 1/4" plywood underneath instead. To stop heat from travelling too far along the tubes, I like a product called Hot Dam! made by IBS. It is a heat dissipating spray, product #74187 that works very well.

    I received and installed the new probes yesterday afternoon. I took it around the pattern a couple times and it appears the new probes have decreased my EGT's by 100 degrees. This puts me in the 1100 range instead of the 1200 range. If anything else it makes it nicer to look at. 
    Nick, Thank you for posting the picture. 100 MM from the piston skirt is what all the articles I read say. Not sure why the Avid Construction manual said to put the holes out so much further. I have two Rotax 582 manuals downloaded on my phone and either of them mention EGT probe placement. They are newer manuals. It does talk about EGT limits. They must be service manuals and installation manuals. I will find the specific installation instructions and download them also.

    Thanks guys for the info.  I cut out 6 new ribs last night.  My ribs are on 12 centers so I'll be adding 2 per wing plus the butt rib.  I will also add a longer wing spar stiffener that Suberavid suggested.  At the moment everything is in the hanger but I am trying to get the shop reorganized so I can bring it over for the winter, then I'llget somepics.
    Thanks again for the help.

    Great photos Randy, it looks fantastic. But you be safe out there... I've just seen some really scary photos of a bushpilot who got surprised by a bear and got badly beaten up before his friend could save him!

    Hi Kenneth, Yep, the electric fence lets you sleep better at night.  I don't know if it has been actually put to the test but so for has worked 100%.
    I built a set of tip stall fences and I think they help a bit at slow speed but not dramatic.  The bad thing is they collect a lot of leaves in tight strips.  I like the new extended wings though, especially when the plane is loaded.  It gets off much better and more able to control at the very edge of the stall and arrest the sink rate with much less throttle.
    Wow, you have been busy! I read your recent post. talk about getting things done!
    Great to hear from you,
    Randy

    I built new 16.5" extended HH wings (same length as the Magnum wings) for my Avid+.  I also doubled the spar insert length to 36" and tripled the strength, plus extended my lift struts about 11" farther outboard and changed the washout to 7/8" over the extended length of the wing, and changed the drag struts from aluminum to 4130 Cr Molly.  I was fortunate enough to have Chris B. give his experience with the flexing of his extended wings while I was early in the build process of mine so could make adjustments to extend the lift struts which I didn't originally plan to do.  I extended the length of my flaperons by 18" also and have no issues with the flaperons binding so be sure to take measures to strengthen your wing if you decide to extend them.  More info on my wing build is in the Fat Avid /Avid Plus section.

    Thanks. It's Dollar Tree foam board otherwise known as Rediboard. Its 20 x 30 x 1/4" thick with paper facings on both sides. The RC guys like it for making their models.  To get the paper off just soak it with water left it dry THOROUGHLY, then the paper usually comes off in one piece.  I've been using packing tape along the edges that i want to be a little stiffer. Overall it is pretty easy stuff to work with.

    I got a kit monday that comes with all kinds of different ends and 15ft of cable and housing. I'll be making them this weekend.

    Just to add to that.  I'm a few away too.  Mine is 1199D and was delivered June 1992.  That gives better idea of time frame/era of manual and serial numbers. I have all order and delivery papers confirming this.  Cheers Randy

  23. Turbo added a post in a topic Throttle cables   

    I bought a 1/4" brass rod, and found that the bike cable can be securely soldered to a small hole drilled perpendicular to the rod's axis.  This allows you to make up Bowden cables of any length.  I used a propane torch, then cut the slug to length, and cut & filed off the excess cable.  I would be tempted to use leadless solder next time.  I need to make up a double-ended Bowden for my OI pump.

    Just was looking at this thread, and maybe I've noticed and or mentioned this before, but my Avid MK IV is only two away from yours Nick.  Mine is 1176D.  JImChuk

    Another issue that may come up if you make the wings real long, is the flaperons may start to bind.  The longer the wing, the more the tip will be pushed up when under load.  That will also bend the flaperons.  Chris B cut his over length fat Avid wings back because the flaperons would bind in flight.  On the Kitfox 3 and later, the lift struts attach further out on the wing then earlier models, and I suppose Kitfox did that to take care of the increased flexing in the wings as the gross weight went higher.  JImChuk
