Here is my entry for the EDBF contest.Its a Flying Wing called " Dazi" constructed from Corrugated Plastic aka coroplast or correx .It has a wing span of 36" and has a high degree of sweep.I am using my own construction techniques rather than what the design requires , reason bieng diffucilty of sourcing correct length and thickness corrugated sheets.I have constructed two seperate wing halves and joined them together,more about that later .Here is the plan.

Total cost on the airframe less than Rs 1000.

the wing plan is drawn on two sheets of 30" 3mm coroplast each half of the wing on each sheet and cut/creased
according to the diagram.

the cutouts are then joined together.I have used a very simple technique for joining both wing halves the only items required are 3/4mm wooden dowels/carbon tube , cable ties and fibre tape.

This wing will be powered by a brushless motor.Conventionaly the motors are mounted in pusher configuration, whereas ill be using a tractor configuration instead, for ease of hand launching , and cg adjustment.Again i wont be using any fancy mounting system it will be the cheap plastic mount (gws mount) that comes with the artech , esky towerpro motors.

Another design variation is addition of a square balsa stick runing the whole length of the under belly .The benefits will be strength to the wing , mounting place for brushless motor and a holding area for ease of hand launching .

now all that is required is folding the upper surface of the wing halves and taping them with the trailing edge with a fibre reinforced tape .By design the upper surfaces are slightly bigger so they form a nice airfoil shape when correctly folded .

similarly the other side is folded ensuring symetry .strips of coro are then taped on the trailing edge of both wing halves for ailevons.

as the battery and esc will be place inside the airfoil section a hatch is cut out for inserting and removing battery .I have used a piece of coroplast hot glued to the upper part of the wing for strength.

with the airframe ready the total weight is 225 gm minus the electronics

Very nice looking wing. Good luck on completion and Maiden.

Thanks RcSquale !.Have finished installing the electronics today

Good stuff, excited to see the maiden video of this baby!!

Again good luck, whish you all the best.

I see an Assan Rx in there. Just like mine.

Skysailor

It sure is ASSAN, cheap and reliable for general purpose use.

Stickers applied ,all set for maiden.All up weight is 495g including the electronics.

Looking good!
