8842 MG servo-D replaces the following servos:

Power upscale, fast, powerful, waterproof, ideal for 600-700 size helicopters, cars 1/8or any other application requiring a servo quality.

Speed, torque, precision!

-> HV = High Voltage = Power by 2 LiPo live.
-> Motor Coreless
-> Digital
-> Waterproof
-> Development and manufacture A2Pro

High Voltage, which means that the servo can accept a 2S LiPo power directly withoutregulator.
Its use is absolutely not restricted to HV applications.
This servo is also very efficient in 4.8V or 6.0V as shown in the table below.

Because of their great power, for typical use without HV, these servos need a quality diet type LiPo 2S + 6V regulator.
The perfect compromise is obtained with LVR (ref. 78505) and a LiPo pack type approval 2S 2600mAh (ref. 92605)
