Efan....NO!!!!!!!

WE love to hear about the experimental part!!!!! without that we'd never know what worked better ,OR NOT!!! It is the experimental part of this that makes the hobby interesting for curious people such as yourself and myself!!! The beauty of this is....3F is so cheap you can experiment to your hearts desire...in the old days ...balsa,glue,covering,paint....on and on and very expensive ...and costly in time too!!!now ...$1.00,1hour planes have us spoiled!!! You're right ...don't break your radio or stuff.....and please keep us informed about the testing!!! I recommend building the models as designed (and proven)before you experiment on it ,so at least you are starting with something you know works, and won't blame that old guy for designing crummy planes....OK!

We do have your confidence Gene.

Very true. As I said above, I had no doubt that it would fly as designed. My experience with deltas/pies showed that they are very susceptible to slow downs as the AOA increases. I see the BE as a brilliant design to try to take further. Just can't resist the chance to experiment (sometimes even if I want to).

For those that are really,really interested...

in this JWA wing thing....donut, flying toilet seat etc. I just was reading the old NY blimp site and came across an article on the Lee Richards "annular wing"...nice pictures of a model of a plane that was flown "some time ago"...gives reference to Bill Warner article in Model Aviation Jan. '83....anybody seen this?????

flight report...

Flew the Bullseye today, but instead of using a 9x6 prop on my epu-6 I switched to a GWS 11x8 orange prop ....with Hippobatts...I was able to easily hang the model on the prop continuously and had a remarkable climb..FB Rich's Bullseye was even lighter than mine (Kli-polys 850 mah-same motor /prop) and flew even better than mine...His was a full 1.5oz. lighter than mine and on a 6 ounce airplane ,thats a LOT!!!

GPW, does either the heart or bullseye fly any better than the other? I actually like the heart design and I think a blue version will look fairly space-ship-ish.

I have really been wanting to make one, but as I said I have to break things to move on. The Q-Butterfly clone was a fun 1 day project, but it is about to give it's guts to one of those for a little while.

fdisk...

the heart seems to have more delta qualities...maybe it's the sweep of the wings being different...you could "square off" the design a little bit and make it a more "manly "shield shape...do it in black for a stealthy spaceship look...I am assured you will come UP with something cool...

FOR CRAZIES ONLY!!!!!

OFB showed be this video of a really fantastic pilot flying a"Sukalyn" or something to that effect....incredible hovering ...rolling circles ...what a pilot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!! the plane was amply powered by a GWS twin D 4.8 volt motor on 8.4V lithiums .....gearing is 9.? /1 underproped at 12x6....just incredible power ....for those who would have the ultimate at the cost of some motor life...this is your indulgence!!!

And here it is after three unsuccessful flights.

First one was inside a gym. It was a little tail heavy, and the elevator was a tad bit warped. This lead to a nose high stall and then a short recovery to an inverted nose dive right into the hardwood floor. Broke the fuselage in half.

Flight two was in the lobby of the gym because the basketball team was practicing. Flew a bit better but was TOO fast for that small of a space. It flew up and hit the cieling and then nose dived into the floor, breaking the fuselage into three pieces.

After repairing that I went outside with it. I was able to fly it for about 25 seconds before the gusting wind finally slammed it into the ground nose first resulsting in what you see here.

So far I am not too impressed with its flight charateristics. Of course I have been flying the ultra stable and forgiving Frog. I have not given up on the design yet though, I plan on rebuilding and trying again when the wind calms down.

You've convinced me. Will build the Bullseye tomorrow.

There's a EDF-50 BATWING contest in www.foamfly.com!!!!!!!!!!

Man that's really cool. Can it be done with the same Bullseye's structure? How?

Batwing? Why yes...

RookieOne,

I've been putting off the EDF-50 contest to finish my "Purely FOAMy" contest entry. I'll see if I can take some pictures of my prototype bat tonight.

It's more like the UP than the Bullseye, but I've got my hand-toss bat glider flying really well now. (Especially with a Rubber Band Bungee Launch ) The finished bat will have a full airfoil wing for reduce drag, but I'm happy to share my "Batwing" planform, that is easy to cut from a single sheet of foam. I even have the CG for it figure out already.

More tonight.
-Dan

P.S. For folks who can't find the album: Batwing Photo Album
There isn't anything too exciting in there yet, but some cool research photos of what has and can be done...

Thanks Dan. It will be as easy to fly as the Bullseye? (Don't worry GPW, I'll build the Bullseye anyway)

Batwing looks cool in the air.

Regards,
