Short version

For those who don't want to read the manual, at first the two most important Don't Forgets:
Secure the bearing screws with Loctite or 5-min epoxy (after a dry-fit test)! Otherwise they could
get loose and the bearing falls off.
Remove a piece of the white epoxy gap seal lip, to simplify inserting the pin into the flap horns.

Summary of Contents for MKS DS6125mini

  • Page 1 Linear Drive System (LDS) installation tips System overview Fig. 1: LDS parts with example MKS DS6125mini servo (rear mounting clip removed). Short version For those who don’t want to read the manual, at first the two most important Don’t Forgets: Secure the bearing screws with Loctite or 5-min epoxy (after a dry-fit test)! Otherwise they could get loose and the bearing falls off.
  • Page 2 At the flaps an electronic offset is needed to achieve full downward deflection. Recommended range (for Graupner HoTT transmitter, for most other brands smaller values are sufficient): Graupner DS3288 65%-80% DS6125mini 80%-85% Futaba S3150 Set these values in your transmitter and adjust the servos, before continuing. 5 December 2012...
  • Page 3 Freestyler 3 & 4 For the flaps, the pin shall have a mechanical offset towards the leading edge of the wing. A template (12) is supplied, which allows adjustment of this offset angle. With factory-installed flap horns in the wings, the actual mechanical servo offset is given by the position of the bearing support rib and you do not need the template.
  • Page 4 Freestyler 3 & 4 - Press in the pin (already attached to the horn) / Pin (schon am Ruderhorn angesetzt) hinein drücken - Insert the mounting pads (10) below the servo clips and screw them to the servo / Klötzchen hinterher fädeln und ans Servo schrauben - Align the servo and check deflections.
  • Page 5 Fig. 6: Servo covers should be thinned locally in case of using thicker servos. Alternative mounting method with masking tape shown here. Fig. 7: Left: Servo mounting pads for Graupner DS3288 (split such that top part can be removed for servo disassembly). Right: Mounting pads for MKS DS6125. 5 December 2012 page 5/5...
