HBM 690 BBMG High-Speed 16mm HV BL Digital Servo
Equipped with all-metal parts, the Graupner HBM 690 BBMG High-Speed High-Voltage Brushless Digital Servo provides a high level of reliability under extreme conditions with consistent control input performance. Optimized for high voltage (7.4V), all the HBM servos are specially designed around a high performance brushless motor, precision cut metal gears, metal heat sink and metal case.
Providing speed and holding power with low dead-band technology for extra reliability and precision, the HBM 690 BBMG can be programmed to meet your unique specifications via the free Graupner Servo Setup Software.
Though usage is universal across all model types, the Graupner HBM 690 BBMG is ideal as a swash and tail servo for medium to large size helicopters.
