The discontinued Multiplex Jumbo Speed BB is a high-performance, giant-scale analog servo from the powerful Jumbo family, with the "Speed" designation indicating it is tuned for a rapid transit time. It also features a precise and durable dual ball bearing (BB) supported output shaft for smooth, slop-free operation. This servo is engineered for giant-scale applications where a quick response is just as important as high power. It is an outstanding choice for the large ailerons on a 25% to 35% scale 3D or aerobatic aircraft to achieve a very high roll rate. It is also a fantastic rudder servo for enabling crisp, fast snap maneuvers. The character of the Jumbo Speed BB is its agile, giant-scale performance; it allows pilots of very large aircraft to have a control system that feels nimble and responsive, not slow and heavy.
For roboticists, the Jumbo Speed BB's combination of size, speed, and precision is very valuable. It would be an excellent choice for the primary joints of a large but fast-moving robotic arm, or for any large-scale automation task where cycle time is a critical factor. It enables the creation of large robots that can move with surprising speed and agility.
