Radio
When the radio box has cured, set the rudder servo
mount inside the box, at the back of the box. The
rudder pushrod hole is marked “R”.
Move the mount so that the servo arm is centered
in the pushrod hole. Mark the holes in the mount on
the box bottom.
Remove your rudder servo from the mount.
Glue the mount to the radio box bottom in the area
marked. Make sure that it doesn’t slide out of
position while it cures.
You can also screw the mount in place. If so, be
sure to seal the screws on the outside of the box
with silicone .
Glue the throttle servo mounts to the radio box
bottom the same way, only set the servo so that the
servo arm is about ¼ inch off center. This is
because we will be using an EZ connector on the
throttle servo arm, and it is offset about that
distance.
Use a 2-56 pushrod with a nylon clevis on the
throttle end, and an EZ connector at the servo.
Be sure to use the metal retainer on the EZ
connector.
You can use the plastic retainer to test throttle
adjustment, then switch to the permanent retainer.
Notre that we supply a set screw with our EZ
connectors. Makes it easy to use the underside of
the servo arm as shown.
Set the radio box between the ply rails,
behind bulkhead 4.
Now we will make the rudder pushrod.
You have several options as to what to make it out
of. Just make sure it’s strong and stiff
We like to use a 4-40 pushrod, which is threaded on
one end.
We attach the rudder end with the provided (with the
rudder) pushrod connector, and the servo end with a
threaded clevis.
