Hyper EZ - updated with plans


I always have liked the looks of canards, especially Rutan's Long EZ, but also like curves. Using a hyperbolic curve for the wing I came up with this. First flight was this morning, and it's really gentle and maneuverable. I like it. Tomorrow I'll fly indoors and try to get some video.

Specs:
24" WS
60g + batt (mine is 14g)
3 x 4.3g servos
Pico rx
6A esc
10g outrunner rewound

If you subtract 5oz, make the sharp coners smooth, use a KF airfoil, shrink it by 20%, etc

Seriously, though, it is a beaut! I've always liked the Long-EZ, just don't like the plain 'Hershey Bar' canard. The little flares make a big difference IMO.

I sorta hacked one out a few years back. I liked it, once I got the cg figured out

Thanks for the kind words.

I agree about the 'Hershey' canards Gene. I think this had a lot to do with making the full-scale construction a bit simpler. However, it's a lot easier to create curves with foam Mine are also swept back a tad.

Scott, looks really nice. And thanks for sharing your work.

I'm curious what design software, if any, you used for the plans. I didn't notice any such program in the PDF file properties.

BTW, Astronaut Jim Voss has (or had) a Long Eze that I've seen many times at the Auburn-Opelika Airport. If he's still keeping it there, I could get some pics, with his permission, of course.

Best regards,

Thanks again guys. I got a little bit of indoor video today, but we were run out early by 3 bus loads of soccer kids. I'd rather wait for some better footage before posting.

Bill--I use Corel Designer, a leftover from my sign designer days.

Here are a couple of short vids. I tried to show off a bit of speed, aerobatics, and slow flight. Landing is so easy--bring it close, pull up elevator and let it drop.

I am impressed! It flys well and looks very nice! I helped my Dad build a full scale Long-Eze and have flown in one many times. I am excited to give this a try! I have plenty of 3mm depron but no 2mm. Do you see any issues with using 3mm on the whole plane? I have everything except the 10g motor. Is there any off the shelf ones you would reccomend?

Thanks again!
