WATER RUDDER PUSHROD

The rudder on the float is driven by the rudder on

the plane. The diagram on the left shows a typical

pushrod installation.

1.

Take a brass clamp and #2 x 5/16” sheet

metal screw to attach the larger diameter

nylon tube to the fuselage next to the rudder

pushrod exit hole.

2.

Thread a 3-1/4”” double threaded rod into one

end of the smaller nylon tube.

Insert the smaller nylon tube inside the larger

tube on the side of the plane.

Thread a nylon clevis on to the end of the

push rod and connect the clevis to the planes

rudder control horn.

Note: You might have to bend the wire to allow the

pushrod to move back and forth inside the

tubing.
