MKS DS6125-mini and DS6125-H: 2 new kids on the block

The glider servo family manfactured by MKS is expanding with 2 new versions of the already presented DS6125 wing servos.


The MKS DS6125-mini is a shorter version of the DS6125, still with impressive specs with its aluminium case and chrome gears: Torque is a little bit lower than the DS6125 but delivers plenty of power for glider application:
  • Dead band:0.001ms (Default)
  • Control System:+Pulse Width Control
  • Working frequence:1520μs / 333hz
  • (RX) Required Pulse:3.0~5.0 Volt Peak to Peak Square Wave
  • Operating Voltage:4.8~6.0 V DC Volts
  • Operating Temperature Range:-10 to + 60 Degree C
  • Operating Speed (4.8V): 0.12 sec/60° degrees at no load
  • Operating Speed (6V): 0.1 sec/60° dagrees at no load
  • Stall Torque (4.8V): 4.8 kg-cm ( 66.65oz/in)
  • Stall Torque (6V): 5.8 kg-cm (81.0 oz/in)
  • Motor Type: DC Motor
  • Potentiometer Drive: Direct Drive
  • Driver Type: FET
  • Bearing Type: Dual Ball Bearings
  • Gear Type: Chrome gear
  • Programmable: NO
  • Connector Wire Length: 15.0 cm (5.9 in)
  • Dimensions: 30x10x29.9 mm (1.1811X0.39X1.17 in)
  • Weight: 25.26g (0.89oz)


The MKS DS6125-H if the vertical mounting version of the DS6125 Mini, with the same specs expected the case shape.


So which servos for what glider application ?

The DS6125-H will be perfect as elevator servos. It will fit in the slimmest F3X fuselage, and if the servormances tests results are identical to its brother (excellent accuracy, positionning and low bending), will provide a crisp and solid control without any slope of the elevators. 

The DS6125-mini will be prefered for ailerons where the DS6125 will be used for flaps or for large ailerons when needed. For example on a 4 m large sailplane, the DS6125 will be perfect.

MKS is well known in the helicopter world for the quality of their servos. I bet that it will be soon the same in the glider world !!!!

DS6125, DS6125-mini and DS6125-H servos are my choice for my next planes.

  2. Hi Reto,

    The DS6125 can be found at Helidigital.com. The H and mini version are very new servos so I don't know if they are already available. You should ask them.

    Best regards,

    Pierre
