This is the Hitec HS-7940TH High-Voltage 7.4V Ultra Speed Digital Servo. Hitec's fastest standard size servo, the "Ultra Speed" HS-7940TH is designed to operate on a two cell LiPo Pack. Featuring a high resolution "G2" second generation programmable digital circuit and indestructible Titanium gears, The HS-7940TH has the performance and durability you've come to expect from a Hitec servo. Other features in the HS-7040TH include a 7.4v optimized coreless motor, integrated heat sink case, and a top case with two hardened steel gear pins supported by axial brass bushing. 

The HS-7940TH has been designed for applications where speed and response is demanded. Perfect for High Performance Nitro and Electric Helicopters, Aircraft, Cars, and Trucks.
