Freewing S Series 3kg Retractable Landing Gear Controller Instruction Manual

1. Introduktion

This manual provides essential information for the safe and effective installation, operation, and maintenance of your Freewing S Series 3kg Retractable Landing Gear Controller. This controller is designed for use with 64mm or 70mm EDF jet planes and RC planes with a wingspan of less than 1300mm. Please read this manual thoroughly before attempting any installation or operation.

2. Sikkerhedsoplysninger

• Always ensure your RC aircraft is powered off before connecting or disconnecting any components.
• Verify all connections are secure and correct before applying power. Incorrect wiring can damage the unit or other electronic components.
• Hold hænder og løstsiddende tøj væk fra bevægelige dele under drift.
• Dette produkt er beregnet til brugere på 14 år og derover. Opsyn af voksne anbefales til yngre brugere.
• Do not attempt to modify the retracts or controller, as this may lead to malfunction and void any potential support.

3. Produktet er slutview

The Freewing S Series 3kg Retractable Landing Gear Controller provides reliable retraction and extension functionality for your RC aircraft's landing gear. It is available in two main types: the ET8102 for nose gear and the E811 for main gear. Both units are designed to support aircraft with a flight weight of up to 3kg.

4. Specifikationer

Kompatibilitet:

• ET8102 Nose Retracts: Compatible with Freewing 80A6, 80F86, 80Mirage2000.
• E811 Main Retracts: Compatible with Freewing Mirage2000, 80F86, 64A-10, 70REBEL, 70Yak130, 80F5E.
• Other specific models mentioned: ET8101 (for 1400mm P-51 main landing gear), ET8103 (for 64mm A-10 Nose), ET8104 (for 80F5E Nose), ET8106 (for 70mm Yak130 Nose), ET8107 (for 0F-16/70 Hawk Nose).

5. Installation og opsætning

Follow these steps to properly install your retractable landing gear controller:

1. Forbered monteringsstedet: Ensure the mounting surface on your RC plane is flat and provides sufficient clearance for the retracts to operate without obstruction. Refer to your aircraft's manual for specific landing gear bay dimensions.
2. Mount the Retract Unit: Secure the retract unit using appropriate screws (not included unless specified) through the mounting holes on the unit's base. Ensure it is firmly attached to prevent movement during flight.





3. Install the Landing Strut: Insert the 4mm diameter landing strut into the designated hole on the retract unit. Secure it using the provided set screw or mechanism.







4. Tilslut ledningerne: The retract unit features a standard servo connector with three wires: Brown (Ground), Red (Positive/Power), and Orange (Signal). Connect this to the appropriate channel on your RC receiver or flight controller. Typically, a dedicated gear channel is used.
5. Test funktionalitet: With your RC system powered on and the aircraft securely supported, test the retracts. Ensure they extend and retract smoothly without binding or excessive noise. Adjust endpoints on your transmitter if necessary to prevent over-rotation or stalling.

6. Betjening

Once installed and configured, the retractable landing gear operates via a switch on your RC transmitter, typically assigned to the gear channel. Activating the switch will command the retracts to either extend or retract. The units are designed for a 90-degree rotation, with a speed of approximately 1.1 to 1.3 seconds depending on voltage.

Ensure the landing gear is fully extended before takeoff and fully retracted after takeoff to reduce drag. Before landing, ensure the gear is fully extended and locked into position.

7. Vedligeholdelse

• Regelmæssig inspektion: Periodically inspect the retract units for any signs of damage, wear, or loose connections. Check the mounting screws for tightness.
• Renhed: Keep the retract mechanism free from dirt, dust, and debris, especially after flying in dusty or grassy conditions. A soft brush or compressed air can be used.
• Smøring: Lightly lubricate moving parts with a suitable plastic-safe lubricant if you notice any stiffness or increased friction. Avoid over-lubrication, which can attract dirt.
• Ledningsintegritet: Check the wiring for any fraying, cuts, or damage. Repair or replace damaged wires immediately.

8. Fejlfinding

• Retracts Not Operating:
  • Check power supply to the receiver/flight controller.
  • Verify the retracts are correctly plugged into the receiver's gear channel.
  • Ensure the transmitter's gear switch is functioning and assigned correctly.
  • Undersøg ledningerne for brud eller løse forbindelser.
• Slow or Erratic Operation:
  • Check for any binding or obstruction in the landing gear mechanism.
  • Sørg for, at driftsmængdentage is within the specified range (4.8V-6.0V). Low voltage kan påvirke ydeevnen.
  • Clean and lightly lubricate the moving parts.
• Retracts Not Fully Extending/Retracting:
  • Adjust the endpoints or travel limits for the gear channel on your transmitter.
  • Check for physical obstructions preventing full travel.

9. Brugertips

• Kontrol før flyvning: Always perform a functional check of your landing gear before each flight.
• Glat betjening: If your retracts feel stiff, a small amount of dry lubricant (like graphite powder or silicone spray) can help ensure smooth operation without attracting dirt.
• Ledningsføringsstyring: Secure all wiring to prevent it from interfering with moving parts or becoming damaged during flight.
• Vægtfordeling: When designing or modifying your aircraft, consider the weight and placement of the retracts to maintain proper balance.
