Repairing a heavily damaged scale shell or replacing cracked rotor mechanics after a severe crash can be time-consuming and expensive. For experienced pilots who already own a compatible transmitter and battery ecosystem, purchasing a complete RTF bundle leads to unwanted transmitter clutter and extra shipping costs. The RC ERA C189S BNF Helicopter (Bind-and-Fly) offers the ideal solution. Completely pre-assembled with factory-installed dual brushless motors, optical flow sensors, dynamic micro servos, and the main control board, this BNF aircraft lets you quickly bind to your existing transmitter and resume smooth, scale-realistic hovering without tedious mechanical assembly. Ships worldwide.

Install Tips
Transmitter Frequency Binding: Turn on your transmitter in binding mode, insert the flight battery into the helicopter, and wait for the status LED to turn solid, confirming successful connection.
Inserting Flight Battery: Slide your 7.4V LiPo battery (sold separately) into the bottom nose compartment until fully seated, securing the latch to ensure optimal center of gravity.
Inspecting Blade & Linkage Freedom: Unfold the main rotor blades and gently move the swashplate linkages by hand to ensure smooth, unhindered mechanical travel before spooling up.
Pre-Flight Gyro & Sensor Calibration: Place the aircraft on a flat, level surface and execute the stick-calibration sequence to reset optical flow and gyro sensors before takeoff.
