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 (opens new window) frame and Pixfalcon have been discontinued. Alternatives are provided in the Purchase section.

Purchase

Vehicle frame options:

• WL Tech XK X450 - Banggood (opens new window), AliExpress (opens new window)
• JJRC M02 - Banggood (AU) (opens new window), AliExpress (opens new window)

Flight controller options ():

• Pixhawk 4 Mini
• Holybro Pixhawk Mini.
• Any other compatible flight controller with small enough form-factor.

Hardware Setup

The vehicle needs 7 PWM signals, which must be connected to the flight controller outputs as specified in Airframe Reference > VTOL Tiltrotor > E-flite Convergence. This mapping is reproduced below.

Port	接口定义
MAIN 1	右电机
MAIN 2	左电机
MAIN 3	尾电机
MAIN 4	空
MAIN 5	右倾转舵机
MAIN 6	左倾转舵机
MAIN 7	右翼升降舵
MAIN 8	左翼升降舵

Note that left and right in the 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.

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.

PX4 Configuration

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

The particular settings that are relevant to this vehicle are:

• Airframe
  • Select the airframe configuration E-flite Convergence under VTOL Tiltrotor and restart QGroundControl.
• Flight Modes/Switches
  • As this is a VTOL vehicle, you must assign an RC controller switch for transitioning between multicopter and fixed-wing modes.
