RC ERA C123 (EC135) – 1:36 Flybarless Brushless RC Helicopter
The RC ERA C123 EC135 (Stock Number YYC123) is a fully functional 1:36 scale flybarless RC helicopter that combines precision control with high realism. Equipped with dual brushless direct-drive motors and a triple-stabilization system (6-axis gyro, optical flow, and barometric altitude hold), it delivers smooth, stable, and efficient flight performance.
Key Features
• 6-channel flybarless single-rotor design
• Dual brushless direct-drive motors (main & tail)
• Optical flow localization + barometric altitude hold
• One-key takeoff/landing & one-key 3D stunt
• Modular 11.1 V LiPo battery with indicator
• Scale EC135 body with LED navigation lights
• Low-voltage / failsafe protection
• Three selectable flight modes for different skill levels
Direct-Drive Brushless Power System
The C123 adopts dual brushless motors — one for the main rotor and one for the ducted tail (“Fenestron”) unit. This direct-drive setup eliminates fragile gears, offering quiet operation, higher efficiency, and reduced maintenance while improving throttle response.
Triple Stabilization System
With a 6-axis gyro, optical-flow sensor, and barometric altitude hold, the EC135 maintains rock-steady hovering and precise position hold even in light wind. Ideal for pilots transitioning from coaxial or FPV models who need stable performance and confidence-building control.
Flight Control & Flight Modes
The 2.4 GHz 6-channel transmitter provides accurate throttle, pitch, roll, and yaw control. Three flight modes allow pilots to progress from beginner to advanced. One-key takeoff and landing simplify operation, while the one-key 3D stunt button enables controlled flips and rolls in open areas.
Modular Smart Battery
The included 11.1 V 400 mAh modular LiPo battery features a built-in charge indicator and secure quick-latch mount. Each pack offers around 8–10 minutes of flight and recharges via USB in about 60 minutes. Swappable packs make extended sessions easy.
Authentic EC135 Scale Appearance
The body replicates the full-size Eurocopter EC135 with fine surface detailing, molded doors, and light housings. Integrated LED navigation lights enhance realism during evening flights or static display.

Available Liveries
Choose from three authentic paint schemes:
• Blue/White Police – modern patrol helicopter style
• Champagne – elegant metallic finish
• Swiss Rescue – bright red-white alpine rescue theme
Stable Hovering & Smooth Flight
Designed for both indoor halls and calm outdoor conditions, the C123 performs stable hovering, forward/backward flight, side slides, and smooth turns. The lightweight PA/PC frame and efficient brushless setup ensure responsive control and balanced handling.

Dimensions
Main rotor diameter 251 mm; fuselage length 281 mm; height 92 mm; typical take-off weight ≈169 g.

Transmitter Overview
The included transmitter integrates throttle stick, trim adjustments, mode selector, and one-key controls. The ergonomic grip and precise gimbals provide a solid feel for pilots learning collective-pitch reflexes on a micro-scale platform.

FAQ
Q1. Is the RC ERA C123 EC135 suitable for beginners?
Yes. The C123 is designed with a 6-axis gyro, optical-flow positioning, and barometric altitude hold to ensure exceptional stability. Its one-key takeoff/landing and triple stabilization system make it ideal for first-time pilots learning coordinated control.
Q2. What is the typical flight time and range?
Each 11.1 V 400 mAh battery provides around 8–10 minutes of flight. The 2.4 GHz transmitter offers a control range of approximately 120–150 meters in an open area with minimal interference.
Q3. Can it perform 3D or stunt maneuvers?
Yes. A dedicated “one-key 3D” button allows simple roll demonstrations when enough altitude and open space are available. This feature is meant for gentle aerobatics, not advanced inverted flight.
Q4. How do the flight modes work?
The transmitter includes three flight-mode levels that adjust control sensitivity and gyro assistance. Beginners can start with Mode 1 for smooth, stable handling and later progress to Mode 3 for faster, more agile response.
Q5. What batteries does the transmitter require?
The transmitter uses 4 × AA batteries (not included). Always install fresh alkaline or high-capacity rechargeable cells for best signal stability.
Q6. Are spare parts and extra batteries available?
Yes. Spare main and tail blades are included in the box. Additional modular batteries and accessories are available from our store’s RC Helicopters collection.
Q7. How should I maintain the helicopter?
Keep the rotors clean, avoid flying in strong wind, and check that all screws and connectors are secure before each flight. Charge the battery only with the supplied USB cable and allow it to cool between flights.
