HORIZON HOBBY Cessna 400 1.1m Aeroplane Instruction Manual

Product Overview

The Cessna 400 1.1m is a sophisticated radio-controlled hobby aircraft designed for pilots with basic mechanical ability. This model requires careful assembly and responsible operation to ensure safety and longevity. It is not a toy and is recommended for users aged 14 and older.

Safety Precautions

Operating this aircraft involves inherent risks. Always maintain a safe distance from people, vehicles, and obstacles. Never operate the model with low transmitter batteries, and ensure the aircraft is always in sight. Avoid water exposure, as moisture can damage sensitive electronics. Always remove the propeller when performing maintenance or testing to prevent accidental injury from the spinning blades.

Assembly and Setup

The assembly process involves installing the horizontal stabilizer, rudder, wing, landing gear, and antenna. Use medium CA glue where specified and ensure all connections are secure. The recommended receiver is the Spektrum AR630. Proper installation of the receiver and correct orientation are critical for flight stability. Always perform a control direction test before your first flight to ensure all surfaces move in the correct response to transmitter inputs.

Battery and Center of Gravity

The aircraft is designed for a 3S 1300mAh Li-Po battery. Ensure the battery is fully charged and securely fastened using the provided hook and loop straps. The Center of Gravity (CG) is measured from the leading edge where the wing meets the fuselage. Achieving the correct CG is essential for stable flight; adjust the battery position forward or aft as needed.

Maintenance and Troubleshooting

Regular maintenance includes checking all linkages, ensuring servos are functioning correctly, and inspecting the motor and propeller for damage. If the aircraft fails to bind or respond correctly, consult the troubleshooting guide to check for common issues such as incorrect transmitter settings, loose connections, or low battery charge. Always disconnect the flight battery before performing any motor or electronic service.

Flight Preparation

Before flying, ensure the failsafe is properly set. During the first flight, trim the aircraft for level flight at 80-100% throttle. If the model does not track straight on the ground, adjust the nosewheel pushrod length. Always follow local regulations and safety codes, such as those provided by the FAA and AMA, to ensure legal and safe operation.
