Programmable 12 Bit Digital Circuit: Using the DPC-20 PC interface or similar compatible Hitec programming software, users can program a variety of features in the HSB-9XXX Series including: Fail Safe On/Off and Position, direction, EPA, Speed (Slower), dead Band, and Soft Start. Power Efficient Brushless Motor Controller: Energy efficiency is a common interest for all modelers. The HSB-9XXX Series uses the latest control circuit technology including a regenerative braking circuit which puts power back into the battery as the motor slows. This feature, combined with ultra-low current draw under sustained loads, allows Hitec brushless servos to consume 1/5 the power of most other brushless servos on the market today. Custom Brushless Motor: Designed by Steve Neu exclusively for the HSB-9XXX Series, these high-performance, brushless motors provide longstanding durability and performance. Constant Torque Output: Thanks to revolutionary circuit and motor designs, the HSB-9XXX Series maintain their speed in a more consistent manner, regardless of load. Hybrid MPD 1st Gear: Hitec’s unique ultra-durable Metal/Plastic/duralumin hybrid first gear prevents inadvertent electrical noise from affecting other components within your aircraft or vehicle. Industry-Leading Titanium Gear Train: Hitec was the first manufacturer to utilize low wear Titanium gears in their servos and continue to be the leader in Titanium gear technology. 25-Tooth Standard Spline: : Hitec Brushless servos utilize a standard 25-tooth output spline for maximum compatibility with the large variety of aftermarket horns available on the market.
