"ESKY professional gyro:sensors adopts piezoelectric crystals. It has the advantages of quick response, high accuracy, little power consumption, long life, light weight. Temperature is the death-wound of piezoelectric gyro, which would lead to migration of neutral point, Fortunately piezoelectric gyroscope internal temperature is automatically correct design. The perfect combination of ESKY professional gyro with the fail drice will provide you more stable and sensitive flight performance."
