This is the Futaba GY520 Heading Hold Gyro.
FEATURES: Ultra small and light weight gyro contained in one unit-no separate sensor and control unit
Utilizes a high speed advanced PID (Proportional-Integral- Derivative) control algorithm
Latest MEMS (Micro-Electro-Mechanical Systems) allows complete control system on one chip
Delivers superior performance with analog servos and excels with digital servos
F3C and 3D mode selectable, six programmable parameters
Operates at very high speed; 280Hz in the 1520uS mode and 506Hz in the 760uS mode
Programmable through single button and multi-color LED or through a PC using Futaba CIU-2 USB adapter
Registered AVCS (Angular Velocity Control System) architecture
achieves unmatched tail holding ability
One year limited warranty
