In a flying wing that uses two control surfaces a separate servo is used for each and these are plugged to separate channels on your rx.

A radio system (transmitter) must be used that has 'Elevo function' and this mix must be enabled to have both elevator and ailerons functions.

Years ago the normal method was to mount one servo on a slider and it was in turn moved by the second servo. One of those was plugged to the elevator and the other to the ailerons.

Designing your own airplane to learn how to fly with is a receipe for failure. Get Help. What exactly is the radio system you are going to use?
