PX4 自动驾驶用户指南 (v1.14)

# E-Flite Convergence 倾转旋翼 （Pixfalcon）

The E-Flite Convergence (opens new window) can easily be converted to a fully autonomous VTOL with PX4. There is not much space but it's enough for a Pixfalcon flight controller with GPS and telemetry.

注解

The original Horizon Hobby E-Flite Convergence frame and Pixfalcon have been discontinued. Alternatives are provided in the Purchase section. :::

# Hardware Setup

The vehicle needs 7 PWM signals for the motors and control surfaces:

  • Motor (left/right/back)
  • Tilt servos (right/left)
  • Elevons (left/right)

These can be wired to flight controller outputs more-or-less in any way you want (though outputs for motors should be grouped together, and so on).

The outputs are configured in the Actuators Configuration by following the instructions for VTOL tiltrotor geometry and output configuration. Note that you will need to start from the Generic Tiltrotor VTOL frame.

Note that left and right in the configuration screen and frame reference are defined from the perspective of a human pilot inside a real plane (or looking from above, as shown below):

# Flight Controller

The flight controller can be mounted at the same place the original autopilot was.

Mount Pixfalcon

# Telemetry Radio

The telemetry module fits into the bay meant to hold FPV transmission gear.

# GPS

For the GPS we cut out a section of foam inside the "cockpit". That way the GPS can be put inside the body and is nicely stowed away without compromising the vehicle appearance.

Mount GPS

# PX4 Configuration

Follow the Standard Configuration in QGroundControl (radio, sensors, flight modes, etc.).
