Servo PowerHD R12S - low profile - standard
High Voltage servo with 12 kg·cm of torque at 7.4 V: the PowerHD R12S runs on 6 V to 8.4 V, so it covers the range of a 2S Li-Po pack.
- The motor is coreless, and the gearbox gears are made of titanium and aluminium
- The output shaft turns on two ball bearings
- The servo works with a 333 Hz signal, measures 41 x 20 x 26.4 mm and weighs 48 g

High Voltage servo for 6 V to 8.4 V power supply
The PowerHD R12S servo runs on a supply voltage of 6 V to 8.4 V and delivers 12 kg·cm of torque at 7.4 V and 9 kg·cm of torque at 6 V, while weighing only 48 g. It is driven by a coreless motor, meaning a motor with a rotor without an iron core, housed in a black case.
The supply range covers the voltage of a 2S Li-Po pack, i.e. two cells connected in series: from a nominal 7.4 V to 8.4 V when fully charged, in line with the High Voltage marking on the case. The case measures 41 x 20 x 26.4 mm, and the servo operates from -10 °C to 60 °C.

Metal gearbox and two ball bearings
The R12S gearbox gears are made of titanium and aluminium, and the output shaft turns on two ball bearings that transfer the load from the servo horn to the case. At a 7.4 V supply the manufacturer specifies a travel time of 0.06 s, and at a 6 V supply a travel time of 0.07 s.
The servo works with a 333 Hz signal, and a pulse of 1520 µs sets the horn to the middle, i.e. neutral, position. Settings can only be changed with the Power HD programmer.
Is it the right choice for you?
A good choice if:
- you power servos directly from a 2S Li-Po pack with a voltage of 7.4 V to 8.4 V
- you need 12 kg·cm of torque in a case 26.4 mm high
- your receiver or controller sends a signal with a frequency of 333 Hz
Consider another option if:
- the servo will work in water: choose the PowerHD LW-20MG or LW-30MG
Fun fact
Lifting capacity 250 times the servo's weight
A torque of 12 kg·cm at 7.4 V means that the R12S can hold a weight of 12 kg on a 1 cm arm, which is 250 times its own weight of 48 g, and a weight of 6 kg on a 2 cm arm.

Frequently asked questions
Can I power it from a 2S Li-Po?
Yes. The servo supply range of 6 V to 8.4 V fully covers the voltage of a 2S Li-Po pack, from 7.4 V to 8.4 V.
Will it work on a 5 V supply?
For the R12S the manufacturer specifies a supply range of 6 V to 8.4 V, so at a 5 V supply the servo operates outside the specification and you should not rely on it.
What signal controls the servo?
A PWM signal with a frequency of 333 Hz. A pulse of 1520 µs sets the servo horn to the middle (neutral) position.
