This is the Hitec D950TW D-Series Titanium Servo.
The titanium D-950TW is part of the Hitec D-Series dynamo servo line. All Hitec D-Series servos have been designed using brand new, cutting edge, custom engineering. Combining industry leading high-resolution, state-of-the-art ultra-response technology with a 32-bit MCU and 12-bit ADC for unprecedented programmability and flexibility, these servos deliver significantly smoother movement. The speedy, powerful line operates on a wide 4.8 ~ 8.4 voltage range, allowing use with any common battery chemistry without the need for adapters or regulators. Featuring Hitec’s industry standard 25-tooth output spline with 3mm hex screw, each D-Series servo brings monster performance never known before in the market.
Note: Programmable features require Hitec Servo Programmer sold separately HFP-30 and DPC-11
A note on Coreless motors: conventional servo motors have a steel core armature wrapped with wire that spins inside the magnets. In a Coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of the magnet eliminating the heavy steel core. This design results in smoother operation and faster response time.
