Thanks for the forums guys All done on paper sketches for the YB-35 - CAD work starts now! Will start a topic when I have something to show.
Thanks again!
Andy.

Feel free to start a discussion thread about your project. You don't need CAD to post. Just a description and wing span will get me subscribed.

Second that.I find the whole design development process fascinating.(it will save you having to answer all the how and why questions later)

The name is a bit confusing, but it will do just fine as flying wing lover will find the forum.

I think there is great possibility for using foam, such as depron, to create these wings. Not using the kFm airfoil series, but as skins over a lightly built structure (the structure already containing the twist, or twist heated into the skins.

Hey Rob,

There are at least a few examples of this type of construction on the European forums. It can be a quick, low risk and reasonably low cost way of building a wing. If it gets people designing and/or building their own wings then I'm all for it.

IMHO the Nurflugal title could stand as it is,without any qualifying description.Anyone interested in the design and build of flying wings will have come across the term and know what to expect.As Brian says,the continental groups feature all types of construction,materials and motive power.

Hey Guys I've been lurking here for a few days and thought i'd say something. I've been flying tailless aircraft since the early 80's. All of them have had some sort of yaw stabilization. Weather it was twist in the wing, beveled wing tips or vertical fins. It didn't matter how yaw stability was achieved even if a vertical fin was suspended way behind the wing on a boom. The thing that makes Nurflugal what it is, IMHO, is the absence of a separate horizontal stabilizer. The wing does all the lifting and pitch stabilizing without help.

That being said. Here's a couple that I've been playing with lately.

These are made form midwest Cellfoam88. At 24 inches good for indoor and calm air.

Foamies don't have to be flat plates or molded. Here's another one of mine yet to be covered. Made of fan fold foam. The spar is vertical foam which is wrapped with 1/4in wide fiberglass reinfroced packing tape.

Are these the"David"designs ? I was looking for a simple to build wing to make with my grandson,these could be ideal.

They are what I "T-LAR designs (That Looks About Right). Based on my experiance of what works. Here are the basic dimensions. Wing root including the elevon is 6 inches. The tip is 3 inches. The span is 24 inches with a sweep of 60 degrees measured at the leading edge. The elevons are 2 inches at the root and1 1/4in at the tip. There is a slight airfoil sanded into the 3mm foam. The LE is sanded to 1/3 back on the top and TE is sanded on the bottom to the hinge line. There is cellophane tape on the leading edge which completely covers the sanded area on the top and covers the bottom to about one inch back. This adds a lot of strength without using carbon fiber. The tip sails are made from foam dinner plate material. I use the Spektrum AR 6400 Rx and the motor/gearbox from the parkzone P51. The prop is cut down to 31/2 inches. All up weight is 32 grams with a 150mah single cell on board. I hope this is helpfull. If you need more info just let me know.

I know nothing about these little E gliders. An AUW of 32gm is amazing. I have batteries that weigh more than that. Love those build in servos! What a great way to get into RC. Every body should start with this type of glider.

You can post your stuff here in the "Use it or Lose it" thread if you like, but it'd be better to start a new thread titled "Marcus's amazing flying wings" then just post whatever you like. It doesn't cost any extra.
