Manufacturer MKS



The MKS HV747 is a high quality digital "Coreless" Servo. It has a unique shape that works in conjunction with it's aluminum casing to dissipate heat quickly, just like heat sink would. Another great feature is the two sets of housing screws. With two sets, you can remove the top for easy access to the gears without worrying about the bottom coming apart.

This servo is equipped with a 9mm VR ultra high resolution potentiometer to provide accurate movement and holding power.

The nice thing about coreless servos is that a light weight wire mesh replaces the heavy steel core. By swapping the metal core for something lighter, this servo is able to produce quick acceleration and deceleration, smooth operation, excellent torque, fast response times, and a guarantied quality performance because it operates at low temperatures.

Charging Wire – XT60 to Banana Plug


Short 3 wire to keep tangled wires to a minimum when charging batteries outside of your plane. You can still charge the batteries inside your plane as long as you can get the charger relatively close to the wire or port. Ideal for a multi charger since you won’t have 4 or more super long wires getting tangled and twisted as you try to charge your batteries.
