RC ERA C184 Mini MD500 Helicopter Optical Flow, 4CH Gyro

A scale MD500 RC helicopter from RC ERA that flies smooth and steady thanks to optical-flow positioning, a barometric altitude hold and a 6-axis gyro. Flybarless aerodynamics give it strong, stable power — easy for beginners, fun for hobbyists.

• Optical flow + altitude hold: optical-flow sensor and barometer lock it in place for rock-steady hovering
• Flybarless 6G design: simple 4-channel control with a 6-axis gyro for ultra-stable flight
• Full aerobatics: ascend, descend, forward, backward, side flight, rotation, route flying and funnel maneuvers
• One-key takeoff & landing plus dual-rate switching
• Smart, safe battery: modular battery with power management, level indicator, low-voltage alarm, stall and loss-of-control protection
• Flight time: ~12 minutes · Charge: ~60 minutes via USB · Range: 80–100 m (2.4G)
• Dimensions: rotor 256 mm · body 239 mm · height 93 mm · weight 99 g · brushed main & tail motors

Battery: 7.4V battery included for the helicopter; the transmitter needs 4× AA batteries (not included).
