Build Delta wing
 

Hi!
I want to build my own electric Delta wings. I have some very "begginers" question...
Did the wings have only the Ailerons???
If yes, how to go up/down without the elevators???
Please if somebody can explain because I don't know apsolutly nothing on delta wings.

Thanks...

They are called elevons, and a computerized radio is used to mix the controls to serve as both elevators and ailerons on the same control surface.

So I can't build it with this radios:

Futaba Skysport.

With that radio you will not beable to set up elevons. However you can get a elevon mixer at low cost. They go in line between the Rx and servo.

In the old days before computer mixing we used to build out own mechanical mixers. As a mater of fact dubro used to sell one that mounted on top of a servo. These mixers all consist of one servo in a fixed position and another that would either slide or have a device mounted to the servo arm that would allow a forward and reverse movement. I built one for a micro model with Cannon radio. Much easier if you just bite the bullet and buy a computer radio.

As far as designing and deturmining the balance point on the dellta I have a suggestion for you. Build small balsa profile models at maybe 1/4 scale of the projected design size. Use 1/16" balsa and use this model to find the correct CG and explore gliding properties. Use small washers or some weight to add nose weight until the model exibits a smooth gentle glide. This test will get you real close to the proper CG for the full size model. I have used this techneque for many years.

Enjoy!:D
