This manual provides comprehensive instructions for the assembly and setup of the Hangar 9 Hawk 140-160N ARF turbine jet. It is intended for experienced modelers due to the complexity of turbine-powered aircraft.
Safety and Precautions
This is a sophisticated hobby product, not a toy. It requires caution, common sense, and basic mechanical ability. Always inspect the model before every flight, fly in open areas, and follow the AMA National Model Aircraft Safety Code.
Assembly and Installation
The manual details the step-by-step assembly of the aircraft, including:
- Aileron and Flap Installation: Detailed steps for installing servos, control horns, and linkages.
- Main Retract Installation: Instructions for both overlapping and flush-mounted gear doors.
- Inner Main Gear Door Installation: Procedures for fuselage-mounted doors.
- Nose Gear Retract and Door Installation: Specific steps for the nose gear assembly.
- Turbine Installation: Mounting the turbine and connecting the data lead.
- Fuel System Installation: Routing fuel lines, installing the air trap, and fuel pump.
Setup and Calibration
Proper setup is critical for flight performance:
- Center of Gravity (CG): The recommended range is 11/16–1-1/4 inches (18–30 mm).
- Control Throws: The manual provides a detailed table for Aileron, Elevator, Rudder, and Flap settings, including rates and exponential values.
Preflight and Maintenance
Before each flying session, perform the following:
- Charge all batteries (transmitter, receiver, and turbine ECU).
- Verify radio installation and control surface movement.
- Check all hardware (linkages, screws, nuts, and bolts) for security.
- Perform a ground range check.

Practical help
Common problems
Retract doors binding
Check for obstructions on the wing surface where the door sits. Sanding or shimming the door mounts on the strut may be required.
Fuel starvation
Ensure the clunk in the fuel tank can move freely and the vent line does not contact the top of the tank.
Door alignment issues
Use low-tack tape to hold doors in position while epoxy cures to ensure proper alignment.
Before use
- Charge transmitter, receiver, and ECU batteries.
- Center trims and sticks on the transmitter.
- Bind transmitter and receiver.
- Verify all control surfaces move in the correct direction.
- Perform a ground range check.
- Check all hardware for security.
