STEP 2B: Alternate Vertical Fin Servo Mounting Method
The alternate method for installing the rudder servo is directly in the vertical fin, this method
provides for the use of a traditional linkage arrangement. The advantage of this system is
increase rudder deflection and less chance of surface flutter.
The cut out in bottom of fin measures ¾” x 1 7/8”, cut slot as shown, see photo 24.
From scrap wood fabricate a mock-up of the servo top case; this will serve as a fixture for
locating the servo mounting blocks. See photo 25 & 26 – the servo used for the subject of
this manual was a HiTec HS-245.
Material Servo Blocks:
