Overview
The Hitec HS-85BB is a premium micro ball-bearing analog servo offering smooth, accurate performance in a compact micro footprint. With 49 oz-in of torque, 0.14 sec/60° transit at 6V, and a ball-bearing supported output, the HS-85BB delivers premium analog performance in a micro-size body — making it a popular choice for park flyers, mini helicopters, and small ground vehicles.
It's the Karbonite/resin-gear analog counterpart to the all-metal HS-85MG, offering a balanced, lightweight option for micro RC applications.
