Comprehensive instruction manual for the E-flite Ultra Stick 1.1m, covering assembly, transmitter setup, flight tips, and maintenance.
Table of contents
Product Overview
The E-flite Ultra Stick 1.1m is a sophisticated RC aircraft designed for sport flying. It features advanced technologies including AS3X stabilization and SAFE Select flight protection, which provides angle limits and automatic self-leveling. This model is intended for experienced hobbyists and requires basic mechanical ability for assembly and maintenance.
Safety Precautions
This is not a toy and is not intended for children under 14 years of age. Always operate the aircraft in open spaces, away from people, traffic, and full-size vehicles. Ensure the transmitter is powered on before the aircraft and always keep the model in sight. Never touch moving parts and avoid water exposure to electronics.
Assembly and Setup
The assembly process involves installing the horizontal and vertical stabilizers, landing gear, and optional flap servos if desired. The manual provides detailed steps for motor and ESC installation. Proper transmitter setup is critical; follow the specific instructions for DX, NX, or iX series transmitters to configure dual rates, exponential, and throttle cut settings.
Flight Preparation
Before flying, ensure the control surfaces are centered and the center of gravity (CG) is set to 84mm behind the leading edge of the wing. Perform a range check of your radio system. During the first flight, trim the aircraft for level flight at 3/4 throttle. After landing, adjust linkages mechanically to ensure the aircraft flies straight without excessive trim.
Maintenance and Troubleshooting
Regular maintenance includes keeping moving parts clean and dry. If the aircraft experiences oscillation, check for loose components, damaged propellers, or incorrect gain settings. The manual includes a comprehensive troubleshooting guide to address common issues such as binding failures, reduced flight time, or unresponsive controls. Always disconnect the flight battery after use to prevent over-discharge.
Practical help
Common problems
Reset controls with throttle stick and throttle trim at lowest setting; ensure throttle servo travel is 100% or greater.
Check for loose receiver, damaged propeller, or imbalanced parts; ensure control surfaces are secure.
Ensure flight battery is fully charged; check if propeller is installed backwards or if battery is damaged.
Move transmitter a few feet away from aircraft; ensure bind plug is installed correctly and battery is charged.
Perform the Control Direction Test and adjust settings on the transmitter.
