1.
Gather the following items
(1) Sub fin
(1) sub fin mounting plate
(6) #4 x 1/2” screws
1.
Trial fit the fin into the plate and mark the plate
on both sides of the fin. Remove the covering
inside the lines.
2.
Remove the tail wheel bracket and the bottom
flying wires.
3.
Draw a center line down the bottom of the
fuselage. Fit the mounting plate flush with the
rear of the fuselage and centered on the cen-
terline you drew.
4.
Drill 1/16” holes at the 6 locations and mount
plate using the #4 screws.
5.
Replace the flying wires.
5.
Epoxy the sub fin to the mounting plate.
5.
Seal the servo door with clear tape or a liquid
sealer.
Mount the door using the four #4 screws.
The final item is to measure the width of the
floats from center line to center line at the front
and back. You can adjust the floats with the
wheel collars on the mounts. Get the distance
the same so they will both be tracking straight.
