Generation 2-RDS

RDS is back with more flexibility and a sleeker design!

For the past eight years, IRF Machine Works has manufactured and supplied the original RDS hardware as designed by, long time modeler and innovator, Harley Michaelis. Harley has continued to add touches to his original design, and recently introduced a complete remake, the G2-RDS. We have taken up the manufacture and distribution of this new improved version. The technical advantages of Generation 2 RDS are many and are best explained by reading the documents prepared by Harley himself at:

RDS was designed to provide a hidden, parasitic-drag-free way to move the control surfaces of RC aircrafts. While the first version of RDS accomplished this very well, the 2nd Generation design of RDS offers several improvements:

  • 25% weight reduction in a typical system.
  • Easier installation and more flexibility of wiper angles available.
  • More variation in hinging options. Incorporation of automatic fore and aft adjustability (sliding hex), with maintained rigid rotary movement.
