GY611 w/BL251

Adds a new dimension of control for larger-sized helis.

- A super narrow pulse (760µs) drive system greatly improves servo response; high-speed processing boosts gyro response.
- The high-resolution 12-bit Analog to Digital accurately converts the sensor output to a digital signal.
- Newest generation SMM (Silicon Micro Machine) technology and a low-back aeroform case enhance vibration resistance and neutral characteristic.
- The GY611’s highly precise angular velocity sensor allows the AVCS to perform even better, minimizing rudder neutral position drift and eliminating the need to trim the rudder during flight.
- Includes the latest high performance BL251 brushless motor servo
