Hitec/RCD HRC37945S

This is the HS-7945TH High Volt, Mega Torque, Metal Gear Servo from Hitec. Ideal for high performance aircraft, cars, trucks and larger nitro and electric helicopters where high speed and high torque are needed 7.4V optimized coreless motor designed to be powered from a 2S LiPo battery for extra speed and power (may also be powered by conventional NiCds) Durable titanium alloy metal gears with dual ball bearing output shaft (MK first gear) Programmable features include; Dead Band Width, Rotation Direction, Rotation Speed, End Points/Neutral Points, Fail Safe On/Off, Fail Safe Point, Resolution and Overload Protection (requires Hitec programmer HFP20, HPP20 or HPP21 HRCM4420) Eight O-rings for water, dust and fuel resistance Heatsink case HS-7945TH High Volt Mega Torque Metal Gear Servo with Connector, 1.8" (45mm) round horn, 1.2" (27mm) single arm, 2.3" (59mm) double arm, 2.8" (72mm) double arm, 1.3" (33mm) single arm, 0.87" (22mm) aluminum single arm, mounting hardware and instruction sheet Installing in model and connecting linkage Motor Type: Coreless (7.4V wind) Bearing Type: Dual ball bearing Speed: 6.0V, 0.12 sec/60° 7.4V, 0.10 sec/60° Torque: 6.0V, 250 oz-in (18.0 kg-cm) 7.4V, 319 oz-in (23 kg-cm) Size: 1.57 x 0.79 x 1.5" (39.88 x 20.07 x 38.10mm) Weight: 2.40oz (68g) A note on coreless motors-a conventional servo motor has a steel core armature wrapped with wire that spins inside the magnets. In a Coreless design, the armature uses a wire mesh that forms a cup that spins around the outside of the magnet. This arrangement is much lighter resulting in smoother operation and faster response time. jxs 08/10/10 ir/jxs &
