I wouldn't call it a Marc-IV either, it just might go to his head
Maybe we should just go back to Long-ez-doublewide?

Well, my airplane is gonna be called Co-bucket. Around here, coal bucket is a common word, and coal is paying for my Cozy, so there it is. I'm building a Co-bucket 4.

Hi folks,

Looking for Oshkosh pictures? Canards maybe?

I’ve put out on the web a few hundred of the photos taken Thursday and Friday at Oshkosh. They are broken down into two groups: Canards & General.

You can view them from the link on the News Letter page at: http://www.aerocanard.org

If you have comments on some of the pictures, especially info on who owns them our special history information, let me know at: canards@aerocanards.org

I was pleased to include a few pictures of Cozy s/n 1. Don’t remember the owner’s name, but I’m sure some of you out there will be glad to help me out. I’m hoping to put together a database with the owner of every homebuilt canard out there. I guess it’s time to start rounding up that information and making it available on line! So, send me info!

If you join the CSA, you get a database of builders/flyers who are members. If you join the COZY mailing list, you get a database of builders/flyers who are members. If you talk to David Orr, you'll find that he has a pretty extensive database of builders/flyers.

If you talk to builders/flyers, you'll find that they don't want their personal info posted in public on the web, for the most part, and certainly not by someone they don't know.

Well, the performance graphs on Jack's plane for the blended winglets look better than Nat's on the lower winglet testing. Considering I never saw anything on Nat's except letters in th archives. Are there any out there?

Jack, Mark, The "bar" in your drawing. Not sure what the bar is. Is that a foam cutout from the original block? It also looks like a carved piece of foam wrapped like a spar than inserted deep into the wing tip and winglet.

Chris's performance numbers look impressive except the gas consumpton. Can't believe that plane goes that fast! Amazing! I just might be building another Cozy in the future.

Great reports guys! Wish I was there.

Since Marc's on vacation and I was at the presentation...

This was asked in the forum at OSH as well.

IIRC Marc said the "bar" is a spar, constructed the same as the main wing spar, but curved and then scarfed (overlapping plies to match original spar caps/shear webs) to the main wing spar. Effectively the main spar goes to the top of the winglet, structurally.

Interesting! I'm thinking about incorporating that into my build. I believe that because I have not built my wings & winglets yet that I should be able to cut the nose off the winglet (like you do the wing) and make my spar cap & shear web as one continous layupall the way to the cap on the winglet.

I'll wait for some input from Marc before jumping on that.

I did notice that he thought this was an acceptable mod when applied to the Berkut & Long-EZ which fits with my build.

Yeah, he's giving an educated opinion which is all well and good. I'm in agreement with Marc that there's a lot of extra work for possibly little return on investment for us non-greasy slow pre-220 canards. Nonetheless, others have done similar mods and there are lots of variables out there we just don't have actual public data. I'm sure there will be in the future. You will make differences in flight characteristics for sure in the Cozy AND the Long but we'll see what happens. Maybe just dumb luck in the end. - Sorry, wrong thread. I'll say no more.

Point taken. I dropped a line (offline) to Marc regarding this and am hoping to get some input from him before going down this road. I'm pre-wings & pre-winglets at this point so if I decide to do this, now would be the best time vs. cutting into my wings at a later date. I'll be moving on to my canard this weekend so I have some planning time available.

Actually I gained 10 kts from 150kts up. Just did not have enough complete evidence to include in the presentation. I still have a lot of testing to do and will report as soon as possible, I had a couple of surgery setbacks. My shear web and top and bottom spar caps continue all the way to the top of the winglet.
