The shell is made of lightweight metal CNC processing, with a gong groove design in the middle shell. The appearance is more beautiful and the heat dissipation effect is better.IP67 waterproof performance, suitable for more scenariosIt can be set to pay-in (turntable) mode through the programming cardLong-life brushless motor, more stable performanceUse high-precision metal gearsFully enclosed ball bearings, higher precision and longer lifeUse magnetic sensing potentiometer (can be rotated 360 degrees)It can be programmed through the steering gear programming card (you can set the steering gear rotation angle, position, output power, damping, sensitivity, reset, forward and reverse, locked-rotor protection, etc.).Support high voltage input: 4.8-8.4VBasic parameters:Dimensions: 40.8 x 20.2 x 29.5 mmWeight: 64gWorking voltage: 4.8-8.4VTorque:4.8V: 19 kg-cm6.0V: 23.5 kg-cm7.4V: 26.8 kg-cm8.4V: 30.8 kg-cmSpeed:4.8V: 0.11 sec/606.0V: 0.09 sec/607.4V: 0.08 sec/608.4V: 0.07 sec/60Waterproof rating: IP67Motor type: high voltage brushlessGear type: imported steel gearPotentiometer type: magnetic sensing potentiometerSuitable for: helicopters, fixed wing, remote control vehicles, remote control boats, robots, industrial intelligence, etc.Colour: Blackmaterial: metal Package Contents:1 x servo1 x Metal arm/1 x servo Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
