Who has the biggest electric flying wing or what is the biggest?


I am getting my interest back into getting a huge electric flying soon going. What is the biggest or who has the biggest. I had a friend that has a foam cutting machine cut me and another guy the cores for a 16" Zagi but neither of us starting it yet? I am thinking about putting it together this summer. Just want to get some info about big wings and the setups and maybe the pics. I am planning on using 4 geared endos with 12x8 props on 20cells.
Should be interesting!

I assume you mean 16' and not 16"?

Please take pictures and let us know about a flight report. I think a 16' (if that's correct) flying wing should be pretty impressive moving through the air.

There was a group in Sweden, I think, that had the 16' version flying well. They posted pictures here last year but my initial attempts to search for it failed.

I forget thedimensions, but the solar powered flying wing NASA has to fly real real high has a span probably way over 50 feet.

Yes 16' Feet flying wing, typo error. I'll be putting it together in about a month or so. It should be able to hand launch easy with the 4 endoplasma motors and the wing area of about 7000sq in.

The finished weight of the plane with everything installed should come out at around 10-12lbs. I am going to be using 1 battery pack for every two motors. I'm using (2) 10x1700CP for it.
Ryan Nau is also going to be doing this project. He got the foam cores for it when I bought mine. So they'll be two of them. Formation would be neat!

Yep, I got the cores to it and hopefully will soon get it together and started, I've been working on to much other stuff lately, but I hope to have it flying by mid summer.
There is 6 total pieces to the wing that you have to glue together to make it a wing. I'm going to have it that it will come in three pieces. One middle section where the motors, escs, battery packs, etc will be, and the two outboard wings. But like giant scale planes there is going to be a rod running through the center sections and then have it connect to the out board section like a giant scale, so It'll fit in the back of the truck. I am planning on using two standard size servos for each elevon.
I wanted to use Endos for this project, but it might be a problem. What battery packs cells can handle the amps of two endos? I'll probably use 4 Magnetic mayhems and endos is possible on 20cells using the E3D gearbox and 12x8 props.
What is the thrust difference from and endo and a magnetic mayhem with the E3D gearbox and 10cells. I'm using 10x2400CP pack probably. I guess you use a y connector for dual speed controls?? I am planning on covering it like the tradional red, white, and blue tape sceme, like my new wedgie has.

One of my clubmembers has build 2 Horten flying wings with electric engines. He has build them on a pretty big scale I believe 1:5 His last project was the Horten 9 with 2 AMT turbines. Pictures of this model are on www.amtjets.com The model before this was a Westland Peterodactyl A big flying wing with a wingspan of about 4 meters and a AUW of 20 kilo's with just one electric engine made by Plettenberg model Dino powered by 60 nicads. As soon as i find some pictures of these models i will post them. They are not made of foam so it does not belong here............

Looks like you need a guy ON motorcycle to launch it.

Corey, what are you going to use to power your big wing?
For just one wing on the 16' Zagi, and Astro Geared 90 might do very well with about a 36Cell pack? Would it work? Still trying to decide what setup to use to make this thing work well.
