X6 Quadplane with tip tilting motors

Hello. I am brand new to the Ardupilot scene, having just gotten involved with it. As I understand it, Arduplane supports many different aircraft configurations, including VTOL capabilities. I am working on a VTOL capable aircraft that is similar to a quadplane, but with an additional two motors on each tip of the fixed wing. These tip motors are tilt rotors while the other four are in the standard X-configuration and do not tilt. I have successfully flashed the Arduplane code to the Pixhawk4 I am using, but am confused on which settings are necessary for this to work.

I believe I have the basics down, such as Q_ENABLE, Q_Tilt, etc. However, when I power on the system, the motors continually emit a beep every few seconds, as though they are not configured, and moving the controls on the radio has little to no effect.

I would greatly appreciate any info regarding the proper settings I may need in order to allow the motors to function, and the tilt servos to tilt.

Thanks
