HI CAN SOMEONE TELL ME WHAT MIXING IS AND HOW IT WORKS CAN ANY RADIO DO IT OR DOES IT HAVE TO BE COMPUTERIZED ,I HAVE A FUTABA SKYSPORT 4, I HAVE SEEN SOME PLANES THAT REQUIRE 3 CHANNEL WITH ELERON MIXING
THANKS

Wrong radio,need a programmable radio.ON SOME PLANES THERE IS A DEVICE FOR ELERON MIXING OR A MIXING TRAY.

thanks
 

hey thanks i didnt think my radio can do it, but i still do not realy understand what mixing does

Mixing is where you set up two different control surfaces to operate at the same time by only moving one channel on the radio at a time. For example, commonly when you deploy flaps the nose will pitch up. So you "mix" in a little down elevator. If your flaps are deployed fully you may set the elevator to move about 15% downward to keep the nose level. You don't have to move the elevator stick to correct the pitching effect you get from the flaps. Sometimes on the high performance planes when the elevator is yanked back, and the plane does a hard pull upward, a little torque from the engine applies. Yaws, or rolls the plane left. You might mix in a little rudder, or aileron to counteract the effectof that torque. All you do is pull hard bck on the stick, and the mix that you programmed in applies a little aileron or rudder, depending on what you set-up. It's a way to counteract some of the adverse effects on and aircraft when you do something other than striaght and normal flight. You let that $250 radio earn it's keep and give it chance to help you do some of the flyin :D

It is also used on some planes to combine two functions into one control surface... Flying wings, and Deltas don't have a "tail", so the ailerons have to also act as elevators, and sometimes people make their ailerons simulate flaps too.

Elevator + Ailerons = Elevrons.
Flaps + Aileron = Flaperons

I'm sure there's more you can think of...

Re: Mixing
 

One area that seems to be left out is mechanical mixing. You can by a mechanical mixer that fits on one servo so that a one servo will effect pitch on another servos rotary movement. That is how it was done before computer radios!
