If you are needing power, look no further than the HS-805BB servo. At 6 volts, this servo unleashes an amazing 343 oz-in. of torque. Dual ball bearings, extra thick nylon gears, heavy H-bridge and large output spline enable the HS-805BB to handle almost anything. When assembled in our SPG800 5:1 ratio kit, 1,715 oz-in. of torque is at your disposal. We offer this servo in several configurations, reverse rotation, 180 rotation and continuous rotation for wheeled applications.


 343 oz-in.


 0.14 sec/60

This servo can operate 180 when given a pulse signal ranging from 600usec to 2400usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180 operation.
