RDS -Rotary Driver

The  RDS Rotary Drive system was developed by Harley Michaelis as a low drag aileron and flap drive mechanism.  It uses a direct rotating rod attached to the output spline of the servo. A cranked driver rod slots into a tight fitting box in the aileron.  When the servo rotates, the angled Crank raises or lowers the aileron.

The diagram below shows the installation in my Claim Jumper slope racer.    The wing is blue foam  skinned with 1/16" balsa and finished  with 3/4 oz. glass
