Scroll down(pages 1&2) in this post to see an interesting Cozy canopy mod. Squared off and flush with fuse. sides. http://www.canardzone.com/forum/showthread.php?t=299 http://www.canardzone.com/forum/attachment.php?attachmentid=27&d=1051214628 http://www.canardzone.com/forum/attachment.php?attachmentid=37&d=1051216013

Are the strakes just fuel tanks? I've read that the inboard wing and strakes on these aircraft do very little lifting. What happens aerodynamically if the strakes are removed? Assuming that room for fuselage tanks could be found would the reduction in parasitic drag from removal of the strakes be worth it?

The Defiant is actualy much closer to a tandem wing aircraft than a true canard design. Holomans book does address some of the ramifications of tandem wings. Also very interesting is that the Defiant canard tapers in % thickness while maintaining a constant chord (not counting the tapered chord canard tips). My guess is that Burt very cleverly did this to tailor the lift distribusion of the Defiant canard. Pretty sharp guy, surprise, surprise! John

I too must have too much time on my hands because I'm seriously considering this concept using two corvair powerplants. I actualy flew with Dave Ganzer, the original designer/builder (with Burt's input), in his Gemini way back when. So far I have scaled 3-views of the Gemini, Defiant, Cozy IV, Baird's 2EZ and Velocity to the same scale to compare component placement. I also have Defiant plans and downloaded AeroCanard plans for reference. In addition I've studied Martin Holomans Aircraft Design and Composit Design books as well as several others. It seems a very viable concept not to mention just plane cool (no pun etc., etc.). Why not just build a Defiant you ask. Well I just don't need a 3000lb. 360hp fuel guzzler to carry 2 plus baggage. BTW, I have seen a few pictures of some dude in France that was almost done with a 3/4 Defiant (Baby Defiant?) using Rotax 912's. I am really stoked with this idea. Of course I am also majorly fired up with the idea of building a composite copy of the Siai Marchetti SF-260. Talk about diverse ideas! I'm in the middle of a job change and major relocation to composite building friendly, very dry west Texas. I hope to make a start on SOMETHING in the next six months (finally!). Raiki, feel free to contact me if you want to discuss this further. This could be the start of a really cool couple of projects :-) John

Can anyone direct me to a listing of weights for the various Cozy IV components? The search here doesn't get me much. Thanks. John

Thanks for the input guys. I also like the looks of a straight canard.

O.K. thanks. I used "hard shell" for the search. Looks like it is not a good process.

A search on this doesn't get me much. What is this and where can I find some more info? Thanks. John

What is the reason for going to a canard with dihedral? I'm just curious. John
