Instruccions de muntatge
Follow these steps to assemble your FMS 850mm Ranger Trainer. Ensure all connections are secure and components are properly aligned.
Instal·lació d'ala
Attach the main wing to the fuselage. Ensure it is centered and securely fastened according to the provided hardware. The high-winged design contributes to stable flight characteristics.

Wing Strut Attachment
Install the robust wing struts. These struts are designed to increase wing rigidity and enhance the aircraft's structural integrity. Ensure they are firmly connected to both the wing and the fuselage.

Landing Gear Setup
Assemble the tricycle landing gear. This configuration improves ground handling during take-off and landing. Ensure all wheels spin freely and the landing gear is securely attached to the fuselage.

Muntatge de la cua
Secure the horizontal and vertical stabilizers to the tail section of the fuselage. Verify that all control surfaces (elevator and rudder) move freely and correctly when connected to their respective servos.
Receiver and Battery Installation
Connect your chosen receiver to the pre-installed servos and ESC. Install your flight battery in the designated compartment, ensuring proper balance. Refer to your receiver and battery manuals for specific connection, binding, and charging instructions. Proper weight distribution is critical for stable flight.
Llista de comprovació prèvia al vol
Before each flight, perform the following checks to ensure safe operation:
- Verify all control surfaces (ailerons, elevator, rudder) move correctly and in the proper direction relative to transmitter stick input.
- Check battery charge level for both the aircraft's flight battery and the transmitter's battery.
- Ensure the propeller is securely attached, free from damage, and balanced.
- Inspect all connections, linkages, and fasteners for security and proper function.
- Confirm the flight area is clear of people, animals, and obstacles, and is safe for operation.
- Check the aircraft's center of gravity (CG) to ensure it is within the recommended range.
Instruccions de funcionament
Controls bàsics de vol
The FMS 850mm Ranger Trainer is a 4-channel RC plane. Basic controls typically include:
- Acceleració: Controls motor speed and overall aircraft power, affecting altitude.
- Alerons: Controls roll (banking) of the aircraft, used for turning.
- Ascensor: Controls pitch (nose up/down) of the aircraft, used for ascent and descent.
- Timó: Controls yaw (nose left/right) for directional control on the ground and coordinated turns in the air.
Electronic Fence Feature
This feature provides an added layer of safety. If the aircraft flies beyond a 120-meter GPS positioning point, it will automatically initiate a return. During this return, you maintain control with the remote controller. If no manual input is received, the aircraft will hover at a radius of 30-40 meters above the GPS point, at approximately 40 kilometers per hour and about 25 meters above the ground.
Funció de retorn d'una sola tecla
For operational errors or unexpected situations during flight, simply press the one-key return button on your remote controller. The airplane will automatically fly back to a predetermined point. Similar to the Electronic Fence, you can override this function with manual control during the return sequence.

Manteniment
Regular maintenance ensures the longevity and safe operation of your aircraft:
- Regularly inspect the airframe for any damage, cracks, or loose components. Repair or replace as necessary.
- Check the propeller for nicks, bends, or cracks; replace if damaged to ensure balanced flight and prevent vibration.
- Keep all moving parts, such as control horns, linkages, and hinges, free from debris and ensure smooth, unrestricted operation.
- Store the aircraft in a cool, dry place, away from direct sunlight and extreme temperatures.
- Ensure flight batteries are stored and charged according to manufacturer guidelines to maximize their lifespan and safety.
- Periodically check the landing gear and wing struts for any signs of stress or damage.
Resolució de problemes
This section addresses common issues you might encounter and provides potential solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| L'avió no respon als controls. | Low battery in aircraft or transmitter; receiver not bound; loose connections. | Charge batteries; re-bind receiver to transmitter; check all wiring connections. |
| El motor no gira o l'embranzida és feble. | Damaged propeller; motor or ESC malfunction; low flight battery. | Replace propeller; check motor/ESC connections; ensure flight battery is fully charged. |
| Unstable flight or difficulty controlling. | Incorrect center of gravity (CG); damaged control surfaces; strong wind conditions. | Adjust battery position for correct CG; inspect and repair control surfaces; fly in calmer conditions. |
| Landing gear damage (e.g., nose wheel). | Hard landing; impact during ground handling. | Inspect for damage and replace components as needed. Practice smoother landings and gentle ground handling. |
| Wing strut damage. | Impact; excessive stress during flight or transport. | Replace damaged wing struts immediately to maintain wing rigidity and flight safety. |
