This is the Futaba GY401 Gyro w/SMM Technology! The use of a new extremely small drift SMM(Silicon Micro Machine) gyro sensor virtually eliminates rudder trim changes during flight. Since rudder trim changes caused by changes in tail reaction, torque changes due to wind and other meteorological changes and main rotor rotation variations are automatically cancelled, tail (rudder) operation is easy, making it perfect for beginners.

It's ground-breaking Futaba innovation, resulting in a line of helicopter gyros like nothing you've ever seen. The new GY series feature several high-tech advantages over conventional piezo engineering that make R/C helicopter flying even more stable and reliable.
