Understanding Elevons
 

Hi Guys

I would like to learn about elevons and what their motions are supposed to be when you move your stick up, down, left and right. Can someone point me in the correct direction?

Thanks for any comments,
Kevin

I believe elevons are primarily used on flying wing models where there are only two control surfaces looking like ailerons on a standard plane. These ailerons are driven by two seperate servos on their own channels usually controlled by a computer radio. By using elevon mixing, the ailerons become elevons being able to control both pitch and roll. Pulling ch-2 (elevator) towards you will raise the elevons causing the plane to climb. Pushing ch-1 (aileron) to the right will raise the right elevon and drop the left causing the plane to roll to the right.

you CAN use elevons on standard planes also if you have dual elevator channels. (i run them on my u can do 3d, 30% of motion tied to ailerons) technically they aren't elevons anymore, but ailevators.

You can use elevon on aerobatic models.
Allowing the elevator to also assist the ailerons will make roll movements more pronounced and agressive.

elevon on a flying wing: the aileron function is normal.. just add thhat the control surfaces both move up for up elevator or both mofe down for down elevator.

You can mix this same function in on an aircraft with tailplanes... and its useful for some 3D maneuvers. However its a good idea to have the mix on a 3-position programming switch. Sometimes you want the elevator and ailerons to go the same direction. Sometimes you want them to go opposing directions. Sometimes you want the ailerons to remain neutral (or just operate as ailerons) when the elevator moves.

Elevons are elevators that act both as elevators and ailerons. Most commonly used on flying wings but also common on aerobatic models that need their control surfaces to be very responsive in low wind speeds or prop wash alone<hovering.> Also elavons are commonly used on jets. Particularly F-16's one because if you've ever seen elevators on a jet more that likely they were HUGE. 2 because Jets normally opperate at higher airspeeds they do not need as much control surface as our slower aerobatic models. As a matter of fact issue 5 of Fly R/c has a F-16 turbine model with only elevon to control the pitch and roll axis's.

Wow! Thanks guys. That some great info and gave me some good things to think about and research further. I really appreciate it. (And I was worried that such a vague question would not elicit much of a response!)

I have found that there are many knowledgable people on RCU.
The trick is to make sure you can distinguish between fact and fiction.
