Package Content

The package includes the T1 Ranger VTOL aircraft components, USB wires for the Flight Controller, and other necessary parts for assembly. Prepare your radio, receiver, and battery before proceeding.

Contents:

• T1 Ranger VTOL aircraft components (fuselage, wings, tail boom, stabilizers)
• Flight Controller (FX-405)
• USB wires
• Screws and hardware
• Control horns and linkages
• Battery mount and strap
• Propellers
• Allen key
• Decals

Connecting the Receiver

Connect your preferred receiver to the RC-In port of the FX-405 Flight Controller. Ensure correct connection of the Ground, 5V, and Signal lines.

For Crossfire or ELRS: Connect the receiver to the appropriate UART port.

For SBUS: Connect the receiver to the SBUS port, noting the Ground, 5V, and Signal lines.

Mission Planner Setup

1. Initial Connection and Configuration:

1. Turn on your radio and connect the battery to your T1 Ranger.
2. Connect the provided USB cable to the flight controller's USB port and the other end to your PC.
3. Open the Mission Planner software on your PC. If you do not have it, download it from the HEEWING website: https://www.heewing.com/pages/fx-405-vtol-flight-controller
4. On the Mission Planner interface, select the correct COM port and baud rate (usually 115200) and click 'CONNECT'.
5. After successfully connecting, ignore any errors and proceed. ArduPilot automatically recognizes Crossfire or ELRS input. For SBUS receivers, follow specific setup steps.

2. Receiver Setup (SBUS):

1. Click 'CONFIG' on the top left of the Mission Planner screen.
2. Navigate to 'Full Parameter List' on the left menu.
3. In the search box, type 'BRD_ALT_CONFIG'. Change the value from '1' to '0' and click 'Write Params'.
4. In the search box, type 'SERIAL6_PROTOCOL'. Change the value from '23' to '-1' and click 'Write Params'.
5. Confirm the changes by clicking 'OK'.
6. Disconnect the USB cable, then disconnect the battery. Reconnect the battery to test SBUS functionality.

Note for CRSF/ELRS: Set BRD_ALT_CONFIG = 1 and SERIAL6_PROTOCOL = 23.

3. Radio Calibration:

1. Ensure your radio is on and the receiver is powered.
2. In Mission Planner, click 'SETUP' and then 'Mandatory Hardware' followed by 'Radio Calibration'.
3. Click 'Calibrate Radio'.
4. Follow the on-screen instructions. Move all control sticks and flight mode switches to their extreme positions to ensure the red bars reach the limits.
5. Click 'OK' when prompted. Mission Planner will then display the MIN and MAX PWM values for your radio inputs.
6. Once all sticks are centered and throttle is down, click 'OK' to continue.
7. The system will display 'Completed' after successful calibration.

Assembly of the Plane

1. Tail Assembly:

• Prepare the tail boom, horizontal stabilizer, vertical stabilizer, guide wire, 2x20 screw, 2x6 screw, and a Phillips screwdriver.
• Use the guide wire to pull the servo connector through the tail boom from one end to the other.
• Align the U-shape cut on the tail boom with the stop inside the horizontal stabilizer mount. Ensure the U-shape cut is centered and not pushing on any wires.
• Align and install the vertical stabilizer onto the clip of the horizontal stabilizer.
• Secure the assembly using the 2x6 and 2x20 screws as indicated.
• Attach the completed tail assembly to the main fuselage using the provided nut. Slot the red nut onto the tail boom first, then secure it by sliding the wires into the fuselage. Do not overtighten the nut.
• Connect the elevator servo into the S2 port on the flight controller, observing the Ground, 5V, and Signal orientation.
• Connect the three motor wires together, matching colors (black to black, red to red, orange to orange).

2. Battery Mount Installation:

• Prepare the battery mount, fuselage, battery strap, 2x6 screws, and screwdriver.
• Slot the battery strap through the battery mount and organize wires to prevent them from being squashed.
• Place the battery mount onto the wooden rail in the fuselage, align the screw holes, and secure it with four 2x6 screws.

3. Control Horns Installation:

• Install the control horns onto the main wing and elevator.
• For the main wing, install the control horn through the slit of the control surface and secure it with the latch. The steel linkage should be 46mm in length.
• Ensure the servo horn angle is parallel to the wing surface. Adjust linkage length for proper alignment.
• Install the control horn onto the elevator and secure it with the latch, ensuring the linkage is installed similarly to the main wing.
• Verify that the elevator is parallel to the horizontal stabilizer by adjusting the linkage length.

4. Wing Installation:

• Slot the carbon rod into the main wing.
• Carefully attach the main wing onto the fuselage, ensuring it is properly clipped. Do not attach or detach the main wing while it is powered, as this can damage the electronics.

5. Canopy Latch Installation:

• Slot the latch through the canopy and secure it with the clip, ensuring the flat side of the clip faces outwards.
• Slide the smaller rear canopy towards the rear of the fuselage, ensuring no wires are pinched between the canopy and the carbon rod.
• Slide the canopy with the hatch towards the front and gently press the latch onto the carbon rod to secure it to the fuselage.

6. Propeller Installation:

• Secure the propellers onto the motors using the provided 2x8 screws. Observe the correct orientation of the propellers.
• Ensure the left and right propellers are installed with the correct rotation direction.

The build is now complete. You may install decals or landing gear according to your preference.
