Tauira: F02S
This manual provides detailed instructions for the operation, maintenance, and troubleshooting of your YU Xiang F02S Flywolf RC Helicopter. Please read this manual thoroughly before operating the helicopter to ensure safe and optimal performance.
The F02S Airwolf GPS Smart 6G Flybarless Simulation Helicopter is a high-performance remote-controlled aircraft featuring advanced GPS and optical flow positioning for stable flight, 6G/3D flight modes, and an 8-channel high-precision remote control. Its robust design incorporates high-strength composite engineering material and dual brushless motors for durability and power.

Operating an RC helicopter requires caution. Please adhere to the following safety guidelines:
Manatokohia kei te noho nga waahanga katoa i roto i te kete:
The F02S comes with a 7.4V 1200mAh 25C LI-POLY smart battery. Ensure the battery is fully charged before first use.

Figure 3: The 7.4V 1200mAh Li-Po smart battery, designed for high discharge rates and extended flight time.
The 2.4GHz remote control requires batteries (not specified in package contents, assume user provides or it's internal rechargeable). Ensure it is powered on and ready for binding.

Figure 4: Remote control display showing communication frequency and mode settings. These settings are based on the T20 open-source protocol.
To establish communication between the helicopter and the remote control, they must be bound. The ELRS Receiver enters binding mode by connecting power continuously 3 times.
The F02S supports two primary flight modes, switchable via the remote control:
The F02S integrates multiple positioning technologies for enhanced flight stability and safety:

Figure 5: GPS Satellite Positioning enables intelligent flight operations such as Low Battery Return, Loss of Control Return, Straight-Line Return, and One-Button Return-to-Home.

Figure 6: Optical Flow and LIDAR TOF provide precise altitude hold and balance maintenance, offering high precision and strong anti-interference capabilities.

Figure 7: The GPS Flight Control System enables automatic hovering and automatic return-to-home functions.
The following table details the ELRS Receiver channel switch settings corresponding to various flight modes and functions. These settings are based on the T20 open-source communication protocol. For specific interface and parameter differences, refer to your remote control's instruction manual.
| Hongere | Mahi | Switch Position / Value | Whakaahuatanga |
|---|---|---|---|
| CH1 | Ail | ±100 | Left/Right Roll |
| CH2 | Ele | ±100 | Whakamua/Whakamuri |
| CH3 | Thr | ±100 | Katere |
| CH4 | Rud | ±100 | Te urungi |
| CH5 | SD (Three-position switch) | -100 / 0 / +100 | Flight mode switch: -100: Optical Flow Mode, 0: GPS Mode, +100: Return-to-Home Mode |
| CH6 | SA (Two-position switch) | -100 / +100 | Emergency Stop switch: -100: Control Allowed, +100: Emergency Stop |
| CH7 | SC (Three-position switch) | -100 / 0 / +100 | Auto Route Switch: -100: In GPS mode, from 0 to -100, the aircraft executes circular route command. 0: In GPS mode, route command off. +100: In GPS mode, from 0 to +100, the aircraft executes figure-eight route command. |
| CH8 | SB (Two-position switch) | -100 / 0 or +100 | Manual Mode Switch: -100: Auto Mode (flight mode determined by CH5 three-position switch position). 0 or +100: Altitude Hold Mode (Optical Flow and GPS off). |
| CH9 | SI (Button switch) | N/A | One-Key Inverted Flight: In GPS mode, switch from -100 to +100 to activate the one-key inverted flight function of the aircraft. |

Regular maintenance ensures the longevity and optimal performance of your F02S helicopter.
This section addresses common issues you might encounter with your F02S helicopter.
| Raruraru | Take pea | Rongoā |
|---|---|---|
| Kāore te hērakapa e aro atu ki te mana mamao. | Not bound; low battery in remote or helicopter; interference. | Re-bind the helicopter and remote control. Charge both batteries. Move to an area with less interference. |
| He poto te wa rere. | Battery not fully charged; aging battery; aggressive flying. | Ensure battery is fully charged. Consider replacing the battery if it's old. Fly more conservatively. |
| Helicopter drifts or is unstable. | Uncalibrated sensors; damaged blades; strong wind. | Perform sensor calibration (refer to remote control manual). Check and replace damaged blades. Fly in calmer conditions. |
| Blades not spinning. | Motor obstruction; loose wiring; motor failure. | Check for obstructions. Inspect wiring connections. If motors are faulty, contact support. |
| Return-to-Home function not working. | Tohu GPS ngoikore; he iti rawa nga peerangi kua kati. | Ensure flight is in an open area with clear sky view for strong GPS signal. Wait for sufficient satellite lock before takeoff. |
