Hitec HS-815BB Mega Sail Servo
The HS-815BB Mega sail arm servo has up to 180 degrees of travel and comes with a Heavy Duty 4.5 inch arm, with a dual ball bearing supported output shaft.
RC servos are hobbyist remote control servos typically used mostly in radio-controlled models, where they provide actuation for various mechanical systems such as the steering of a car, the flaps on a plane, or the rudder of a boat. These servos are not industrial grade and are not recommended for continuous heavy use.
Due to its large amount of torque, the Mega Sail Servo will only work with the 1061 – PhidgetAdvancedServo 8-Motor. This servo motor will not operate properly with the Phidgets 1066.
