The can easily be converted to a fully autonomous VTOL with PX4. There is not much space but it's enough for a flight controller with GPS and telemetry.
:::note The original Horizon Hobby E-Flite Convergence frame and have been discontinued. Alternatives are provided in the section. :::

Vehicle frame options:
WL Tech XK X450 -
JJRC M02 - ,
Flight controller options ():
.
Any other compatible flight controller with small enough form-factor.
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).
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):
The flight controller can be mounted at the same place the original autopilot was.
The telemetry module fits into the bay meant to hold FPV transmission gear.
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.
The particular settings that are relevant to this vehicle are:
The outputs are configured in the by following the instructions for VTOL tiltrotor geometry and output configuration. Note that you will need to start from the frame.
Follow the in QGroundControl (radio, sensors, flight modes, etc.).
Select the airframe configuration E-flite Convergence under VTOL Tiltrotor and restart QGroundControl.
As this is a VTOL vehicle, you must for transitioning between multicopter and fixed-wing modes.
