Discontinued: Falcon Vertigo Hybrid VTOL RTF (Dropix)

Discontinued: Falcon Vertigo Hybrid VTOL RTF (Dropix)

Note Discontinued: The Falcon Venturi FPV Wing frame on which this vehicle is based is no longer available.

The Falcon Vertigo Hybrid VTOL is a quadplane VTOL aircraft that has been designed to work with PX4 and the Dropix (Pixhawk compatible) flight controller. It can carry a small GoPro camera.

The RTF kit contains everything needed for a full system except an RC receiver and telemetry module. The components can also be purchased separately.

Key information:

Frame: Falcon Vertigo Hybrid VTOL
Flight controller: Dropix
Wing span: 1.3m

Almost everything you need is provided in the RTF kit (the links next to components below are provided in case you wished to purchase any component separately):

Pre laminated EPP wings
Wingtips and full hardware
Dropix flight controller with
- GPS Ublox M8N
- Power Sensor
- Airspeed Sensor
Quad power set T-Motor
4 x propeller 10”x 5” (quad motors)
4 x ESC 25A
1 x propeller 10” x 5” (pusher motor)
1 x ESC 30A
Pusher motor power system
Carbon fiber tubes and mounts
G10 motor mounts
1 x 3700mah 4S 30C Lipo battery

The kit does not come with a radio receiver or (optional) telemetry modules. For this build we used the following components:

Tools needed

The following tools were used to assemble the airframe:

Philips screwdriver
5.5 mm Hex Socket Screwdriver
Wire cutters
Soldering iron and solder
Hobby stainless steel tweezer
Gorilla glue
Fiberglass reinforced tape

Assembly steps

The RTF kit requires the following assembly.

Step 1: Attach motors mounts

Spread gorilla glue inside the wing brackets as shown.
Attach the carbon tube in the brackets. The bracket and tube must be aligned using the white mark (as shown in the picture).

Note This is very important because the white mark indicates the center of gravity.
The following images show the alignment of rods from other viewpoints:

Step 2: Attach the wings

Insert both carbon tubes into the fuselage.
Spread gorilla glue between the two white marks on each tube (indicated by the red arrows). The white mark in the center (blue arrow) will be placed in the center of the fuselage and the other marks on the sides.
Once the carbon tubes are inside the fuselage, spread gorilla glue on the rest of the tube and attach the wings.
The fuselage has two holes for the motor and servo cables. Pass the cables through the holes and then join the wings to the fuselage.
Within the fuselage connect the signal cables you just passed through from the wings to the ESC using the provided connectors. The ESC are already connected to the motors and set up to turn in the correct order (you will need to connect the ESC PDB to a power module in a later step).
As with the ESCs, the servos are already installed. Connect the signal cable from the wing (passed through the fuselage) to the flight controller.
Repeat these steps for the other wing.

Step 3: Connect the electronics

This kit includes Dropix flight controller with most of the required electronics pre-connected (if you use another Pixhawk-compatible flight controller the connections are similar).

Note General information about connecting Dropix can be found in Dropix Flight Controller.

Connect the ESC power connector and pass the signals cables to the flight controller

Connect the ESC to the power module using the XT60 connector
Pass the signals cables through to the flight controller

Motor Wiring

The outputs of Dropix should be wired using the standard QuadPlane configuration (orientation as if “sitting in the plane”).

Port	接口定义
MAIN 1	Front right motor, CCW
MAIN 2	Back left motor, CCW
MAIN 3	Front left motor, CW
MAIN 4	Back right motor, CW
AUX 1	Left aileron
AUX 2	Right aileron
AUX 3	Elevator
AUX 4	Rudder
AUX 5	Throttle

Flight Controller Connections: Motors, Servos, RC receiver, current sensor

The image below shows back of the dropix flight controller, highlighting the outputs pins to connect quad motors cables, aileron signal cables, throttle motor, and the current sensor and receiver (RC IN) input pins.

Connect quad motors signal cables.
Connect the aileron cables and throttle motor in the auxiliary outputs.
Connect the throttle motor signal cable from the ESC to the appropriate flight controller auxiliary port. Connect the ESC to the throttle motor.
Connect the receiver (RC IN).

Flight Controller Connections: Telemetry, Airspeed Sensor, GPS, Buzzer and Safety Switch

The sensor inputs, telemetry, buzzer and safety switch are located in the front of the flight controller, as shown in the connection diagram below.

Connect the telemetry, airspeed sensor, GPS, buzzer and safety switch as shown.

Flight Controller: Connect power module and external USB

The inputs for the USB port, power module and external USB are located on the right side of the flight controller.

Connect power and USB as shown

Tip The external USB is optional. It should be used if access to the USB port is difficult once the flight controller is mounted.

Install the pitot tube (airspeed sensor)

The pitot tube is installed on the front of the plane and connected to the airspeed sensor via a tube.

Caution It is important that nothing obstructs airflow to the Pitot tube. This is critical for fixed-wing flight and for transitioning from quad to plane.

Install the Pitot tube in the front of the plane
Secure the connecting tubing and ensure that it is not bent/kinked.
Connect the tubes to the airspeed sensor.

Install/connect receiver and telemetry module

Paste the receiver and telemetry module to the outside of the vehicle frame.
Connect the receiver to the RC IN port on the back of the dropix, as shown above (also see the flight controller instructions).
Connect the telemetry module to the front of the flight controller as shown below (see the flight controller instructions for more detail on the pins).

GPS/Compass module

The GPS/Compass module is already mounted on the wing, in the default orientation. You don’t need to have to do anything extra for this!

Mount and orient the flight controller

Set your flight controller orientation to 270 degrees.
Secure the controller in place using vibration damping foam.

Step 4: Final Assembly Checks

The final assembly step is to check the vehicle is stable and that the motors have been set up correctly.

Check that the motors turn in the correct directions (as in the QuadX diagram below).

Tip If necessary the servo direction can be reversed using the PWM_REV parameters in the PWM_OUTPUT group of QGroundControl (cogwheel tab, last item in the left menu)
Check the vehicle is balanced around the expected centre of gravity
- Hold the vehicle with your fingers at the center of gravity and check that the vehicle remains stable.

If the vehicle leans forward or backwards, move the motors to balance it.

配置

Perform the normal Basic Configuration.

备注：

For Airframe select the vehicle group/type as Standard VTOL and the specific vehicle as Generic quad delta VTOL as shown below.
Set the Autopilot Orientation to ROTATION_YAW_270 as the autopilot is mounted sideways with respect to the front of the vehicle. The compass is oriented forward, so you can leave that at the default (ROTATION_NONE).
The default parameters are sufficient for stable flight. For more detailed tuning information see Standard VTOL Wiring and Configuration.
