Quarter scale servo in place on mount.
Rudder servo and pushrod in place.
4-40 solder clevis at servo end.
This mount puts the servo arm in the correct
position for a straight pushrod run to the rudder.
We will use the innermost servo arm hole.
Thread a 4-40 ball link onto a 4/40 pushrod.
Slip this into the hole in the transom and
bulkhead and attach it to the rudder with a 4-40
screw and nut.
Sand the bottom of the servo mount so that it is
flat.
Put the servo/mount assembly in position about 1
inch forward of the rear bulkhead.
Mark the pushrod where the servo output shaft
is.
Remove the pushrod.
Cut the pushrod and solder a clevis in place so
that its pin is where the mark was.
Put the pushrod back in place.
Put a servo arm on the servo so that it is facing
straight down.
Pop the clevis into the innermost hole in the
servo arm and move the servo/mount assembly
around until the pushrod is not touching the hole
sides and the rudder us straight.
Use epoxy to glue the mount in place, again
making sure that the rudder is straight.
Don’t get any glue on the servo or wire.
Allow to cure.
