## Wiring

Wire the servos and motors as shown. Use the `MAIN` outputs (not the ones labeled with AUX). The motor controller needs to have an in-built BEC, as the autopilot is not powering the servo rail.

| Port   | Connection                  |
| ------ | --------------------------- |
| RC IN  | PPM or S.BUS / S.BUS2 input |
| MAIN 1 | Left Aileron                |
| MAIN 2 | Right Aileron               |
| MAIN 3 | Empty                       |
| MAIN 4 | Motor 1                     |

## Build Log

The images below give a rough idea about the assembly process, which is simple and can be done with a hot glue gun.

## PX4 Configuration

### Airframe Configuration

Select **Flying Wing > Generic Flying Wing** in the QGroundControl [Airframe Configuration](../../config/airframe):

![QGC - select firmware for West Wing](https://4155462212-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LArEa7z2SPawfl3HpCD%2Fuploads%2Fgit-blob-4be721e134e4759f30c5293adeb98606021e80d1%2Fqgc_firmware_flying_wing_west_wing.png?alt=media)

### Actuator Mapping

Set up the [Actuator Configuration](../../config/actuators) to match the wiring for the ailerons and throttle as [indicated above](#wiring).

![QGC - set the actuators](https://4155462212-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LArEa7z2SPawfl3HpCD%2Fuploads%2Fgit-blob-48162c83acee0af4023e9bb2f97de73ce18f39cf%2Fqgc_actuator_config.png?alt=media)
