Setup

Your Roban RC Helicopter is supplied as a Ready-To-Fly (RTF) model, meaning most assembly is complete. However, some initial setup steps are required before your first flight.

1. Battery Charging: Fully charge the included 14.8V 3300mAh 35C flight battery using a compatible LiPo charger (not specified if included, assume user has one or it's part of RTF package). Follow the charger's instructions carefully. Never leave charging batteries unattended.
2. Transmitter Batteries: Install fresh batteries into the 10-channel radio control transmitter.
3. Binding (if necessary): If the helicopter and transmitter are not already bound, follow the specific binding procedure outlined in the separate transmitter manual. Ensure the helicopter is powered off before initiating the binding process.
4. Pre-Flight Check: Before connecting the flight battery, ensure the throttle stick on the transmitter is at its lowest position. Verify all control surfaces (swashplate, tail rotor) move freely and correctly in response to transmitter inputs.
5. Secure Battery: Once charged, carefully insert the flight battery into the helicopter's battery compartment and secure it to prevent movement during flight. Connect the battery to the helicopter's ESC.

Operating Instructions

Once setup is complete, you are ready for flight. Always prioritize safety and choose an appropriate flying environment.

1. Power On: With the throttle stick at its lowest position, power on your transmitter first, then connect the flight battery to the helicopter. Wait for the helicopter's flight stabilization system to initialize (indicated by LED lights).
2. Pre-Flight Checks: Confirm all controls respond correctly. Check rotor blades for any obstructions.
3. Take-off: Slowly and smoothly increase the throttle. The helicopter will begin to lift. Apply small, precise corrections with the cyclic (aileron/elevator) and rudder controls to maintain stability. Aim for a smooth, controlled ascent.
4. Flight Controls:
   • Throttle (Left Stick, vertical): Controls main rotor speed and collective pitch, thus controlling altitude.
   • Rudder (Left Stick, horizontal): Controls tail rotor pitch, causing the helicopter to yaw (rotate horizontally).
   • Aileron (Right Stick, horizontal): Tilts the helicopter left or right, causing it to move sideways.
   • Elevator (Right Stick, vertical): Tilts the helicopter forward or backward, causing it to move in those directions.
5. Landing: Slowly and smoothly reduce the throttle while maintaining a level attitude. Aim for a gentle descent. Once on the ground, immediately reduce throttle to zero.
6. Power Off: Disconnect the flight battery from the helicopter first, then power off your transmitter.

Maintenance

Regular maintenance ensures the longevity and safe operation of your helicopter.

• Rotor Blades: Inspect main and tail rotor blades for cracks, chips, or damage before and after each flight. Replace damaged blades immediately.
• Mechanical Components: Check all screws, linkages, and moving parts for looseness or wear. Tighten or replace as needed.
• Motors and ESC: Ensure motors are free of debris and spin smoothly. Check the Electronic Speed Controller (ESC) for any signs of overheating or damage.
• Battery Care: Store LiPo batteries in a cool, dry place at storage voltage. Do not overcharge or over-discharge. Discontinue use if a battery shows signs of swelling or damage.
• Cleaning: Gently clean the helicopter body and components with a soft, dry cloth. Avoid using solvents or harsh chemicals.
