NTRODUCTION
The Futaba ® GY520 is the smallest and lightest heading hold
AVCS gyro available today. Its cutting-edge MEMS (Micro Electro
Mechanical System) sensor design, ultra high-speed processing
speed and advanced PID control algorithm put it a quantum
leap ahead of all other heading hold gyros in size, weight and
performance. The GY520 has been optimized to work with small
electric models and larger nitro (.30 through .91) sized helicopters.
