GY611 is the latest and most advanced Futaba gyro operating at a super narrow pulse of 760µs. The functions of the GY611 includes:

• AVCS gyro. GY611 uses a new type of gyro sensor to achieve a high-precision angular velocity detection function and detect extremely small output drift, maintaining a very stable tail position.
• Super Narrow pulse drive system substantially improves servo response and improve AVCS gyro efficiency, the GY611 is equipped with the latest high torque/high speed rudder servo - S9256.

Dimension: 40 x 20 x 36.6mm
Weight: 57g
Speed: 0.06sec/60°
Torque: 3.4kg.cm

• High resolution 12-bit A/D accurately converts the sensor output to a digital signal.
• Flight mode selection for F3C or 3D. The F3C mode emphasizes tail suppression and stop. The 3D mode will let you control piroutte speed completely proportional wtih the rudder stick operation amount.
