    I know how you made yours - Seeing the Cub on the front of SA this month got me to wondering about adding the corner angles and making mine like that, but moving the angles forward and more up to crossover tube.

    I had nothing but trouble with my WS. I made it into a 3 piece WS. Been using it for a couple years now and no stress cracks yet. The old one piece WS only lasted a few months before cracking.

    TJay,
           Here are 3 pages of Skylight info from the Avid Magnum manual.
    The (CF) Cover and Finish section in the KF1 manual is about 20 pages - If you will PM me your address, I will copy them and mail them to you at no charge - this is easier as I share this computer with a college student - sometimes I get very little access.
         I can also copy the drawing of the bottom plate for the Rotax engine and send it - if you need it.
    I don't like either the Avid or Kitfox turtledeck with the hinge in it that always leaks - The KF One-piece Lexan is a good one, but you have to bend the Lexan - Probably better is to make sides and top separate and join them with aluminum angles.
         Search Turtledeck or "Raising the Skylight" posts on here and you may get some ideas.
    Do you have the drawing of the center support for the Skylight, or any other pages you need - Let me know and I will include it in the mailing.
         Hope this helps - 3 attachments added,
    EdMO

    Akflyer, 
    I was evidently not clear enough in my post. The angle of the cabane was not what the problem was for me. Problem was the gear leg compression not inline with the longeron but pushing under it caused torsion to the longeron. The cabane does not help the issue either as the legs are in tension and are contributing to the torsion issue in most designs. However I actually provided an independent cabane attach point to allow an inline pull on the longeron.
    Hope this helps the explanation, I can take some photos and attach if it would help. I think the best would be the horizontal tube you mentioned to keep the gear attach points from coming together. The angle of the cabane has more to do with the loading on the bungies and the stroke needed during gear deflection. A lower strut attach point with require more stroke for a given tire movement but will require less load.

    I think the cabane gear will work ok on these, but it can't be a straight pull from side to side, the center of the vee has to be dropped down like the Cubs. I had an engineer run the numbers and the straight pull everyone has used so far puts way too much stress on the longereons. I increased the travel on mine as a quick stop gap measure but will soon be fabricating a new vee to change the pull so it will spread the load to both sides, as well as put an additional tube across the top to help keep it from pulling the longereons in.

    I think that by using the bungee on it, the travel part is now taken out of the equation and it won't be going metal to metal and bending things like the original springs did. 1.8 inches of travel is just not enough when your heavy and on a rough surface.

    I know I have posted this before but, the Kitfox and Avid fuselage attach points are not angled properly for a cabane type gear. This causes torsional forces to the longerons. I know this by experience.

    I have not measured the new gear I got, but when avid first started making the wide gear it was 14" wider than stock. That was soon changed to 10" wider due to unforseen issues with going wider than that. Just a little food for thought.

    What have you done to prove out your "bush" gear? Any off airport pics? Any tests at gross to beat them up n make sure it's not going to tweak the fuse?

    I only ask this because I don't want to see a member here get into a bind like the other makers of "bush" gear that was sold untested and pretty obviously not engineered other that using the "that looks about right" engineering method. By changing one angle just a tad you can double or triple the forces on the longereons.

    One last thought.... for "bush" work, you want to be able to keep the tail up out of the rocks and sand etc. By moving the axle forwards you are putting more weight on the tailwheel. This turns the tailwheel into a boat anchor on sand and gravel strips.....

    I don't want to slow ya down or to burst your bubble, I just want to make you aware of the pit falls of selling "bush gear" that have never seen the bush

    I will look at my Kitfox 4 and Avid Magnum manuals and see what I can post on here for you.
    EDMO
    Here is a page from the Kitfox 1 manual - you should have it and some other pages - look at page number. My other manuals are not as clear, but I could make a drawing if you really need it.
    I would make it a 2-piece assembly, and make the front attachment like the rear, without the spacer, and cover with aluminum strip - you may want to put some sealer on the front joint - make sure it is compatable with lexan and Plexiglas. You may want to make the front angle wider so you can bolt both the WS and SL separately to it.
    If you don't have the drawing and directions for fitting the WS to the door frame, I can post it when you need it.
    The SL should be wider to overlap the wing joint - you need to clear the spot where the pin goes into the spar.

    I would sure like to see some directions on how it all works. there is nothing in my build manual about this or turtle deck building

    TJay,
    Those parts are for attaching the windscreen and skylight, and to make a slot for the turtledeck to slide into - some planes have one-piece WS and SL, but I think that is a bad idea - some have had problems with the WS cracking and have had to replace it - no need to have to pay for a larger lexan by having the SL as a part of the WS. I would have to look at my KF1 manual, but there are different ways to do this - I can look at my KF4 manual if you need other ideas. I like my SL to be a dark tint. I use a light bronze for other windows and TD.
    EDMO
    You may rivet the aluminum to the crosstubes, but I think it is better to bolt the WS and SL with rubber or plastic washers under the bolt heads instead of rivets which can cause cracking. This is more work, but could prevent replacing parts later on.

    another kitfox 1 question
    So I have seen a few other kitfoxes with aluminum pieces riveted on the top of the front and rear spar upper carry through tubes, Now on the newer ones I don't see that anymore, I have all the aluminum pieces and rivets and I'm sure I could figure out how to do it , but is it necessary and does it do much

    I'm building a custom wide gear very similar to the Avid bush gear only im using cub style bungees and making it a little wider than the airdale gear. I'm building them for both the Avids and Kitfox. Main tubing is 1" .058 4130. If you are buying one made for the other keep in mind that the cabane will be different. Kitfox had one width and avid had two different widths. FWIW but any of them will be much better than any of the stock gears out there. 
     
    -Robert- 
     
    Here is my last one on a friends Kitfox IV it sits 20" wider 2" higher and 2" more forward than the stock gear that he originally had. Made a whole new plane out of it.

    I believe Bandit said his was a whole lot lighter and got off quicker than the other Avids and Kitfoxes - He has a lot of hours of experience with the 503 - Pardon me - just butting in!
