I have a problem. My design of UAV doesn't have Rudder and Aileron and i only have an elevator for doing roll, pitch and yaw (See the attachment). Therefore, i need to figure out a way to get change in Yaw and Roll in software and hardware. If i look at the diagram of the APM, each movement (yaw, pitch, and aileron) has a channel for its servos. I am confused. Does any one have an idea of solving this problem?

The picture above is drawn very roughly, so ignore the details and try to understand the idea. I don't have a rudder. I only have aileron and elevator. The way elevator works will be just one up and down, so it will turn left or right. pitching is same as the regular plane. my question is that what do i have to change at software?
If that's what you mean, you can see here for the instructions. Scroll down and see the mixing function.
For the APM, just connect to the aileron and elevator pin, and of course the ESC too.
