Remove the stock servo arms from the rudder servo
and replace them with 3D XL 1/2 servo arms. The
arms need to face down as shown. Be sure to use a
drop of threadlock on the servo arm screw if using
metal-geared servos.
 Step 6
Use the included 4-40 screws and nuts to attach the ball
link to the outer hole in the arm. From the topside, the
correct sequence is 4-40 screw, ball link, servo arm and
4-40 locknut. Be sure to use threadlock.
 Step 7
Screw a 4-40 ball link 5 to 6 turns onto the 8" rudder
linkage. Screw the opposite end of the linkage into the
swivel control horn on the rudder. Adjust the linkage
length until the hole in the ball link lines up with the outer
hole in the servo arm when the rudder is neutral and the
servo arm is centered.
