Floats
Many thanks for the purchase of the Floats. This set contains a pair of strong, lightweight floats molded in
special ABS plastic, together with all fittings required, water rudder and associated linkage. The floats is
designed for wooden high wing plane that you can convert to seaplane easily.
Please read the manual thoroughly and check the contents before you start the assembly. You will need

drill bits during assembling. Regarding tools and glues,
they are same as you used for the plane .
Introduction
12.Locate the Angled Brass Tubes and mount, install the
tubes in the mount. Place the Brass Tube Mount as
photo shown then drill 3mm(1/8
”
) hole through the
mount and to the float. Next enlarge the hole on float to
5mm(13/64
”
). Do the same procedure to install the
sleeve. Next secure the brass tube mount on the float
with the rest 3x15mm wood screw.
13.Drill a 3mm (1/8
”
) hole at the left side of the fuselage,
epoxy an angled brass tube in place. Next thread the
wire through the angled brass tube on the float, next
thread the wire through the brass tube on fuselage then
go to the servo compartment. Make a loop and circle to
the servo horn at outmost hole then clamp the tube. Do
the same way on the other wire.
14.Bend the Spring at two ends so it can hook to the
steering arm. Thread the other end of the two wires to the
springs same way to loop the brass tubes. Adjust the wires
and clamp the tubes so springs have the tension. Make
sure the water rudder works smoothly and same direction
as rudder.
Step vs C.G.
Flying Tips
During the slow taxing phase it is essential to hold in full up-elevator to keep the nose up. Taxi as slowly as possible to
avoid spraying and splashing. Use the rudder (i.e. the water rudder) for course correction only; the ailerons should only
be used to hold the model straight in a side-wind. Take-off must always be directly into wind; start by opening the throttle
slowly with full up-elevator held in. As soon as the model rises onto the step , i.e. when it is gliding on the underside of
the floats, the elevator must be returned to neutral. Allow plenty of time, i.e. more than you generally use on land. The
drag of floats is much higher than of a wheeled undercarriage. Always land in plenty of time, i.e. well before you run out
of fuel, as you will need a longer motor run than you are used to when flying from land in order to taxi the model back to
the bank. For the landing fly into wind as usual and flare the model with a higher angle of attack than usual. The waves
can be uncomfortably high, and the model will tend to bounce unless you are very careful.

”
1.Refer to airplane safe cautions.
2.Nylon or fiberglass propeller is recommended.
Also check that there is sufficient clearance between the propeller tips and the top surface of the floats.
3.Only fly when engine is powerful and smoothly.
4.Do not fly on a flowing water like creeks or rivers.
5.Do not attempt to fly if there is any wildlife or people in the water.
6.Check the wind direction then choose a good location for flying. The wind can carry it back to the shore if
engine is quit.
7.If plane is stuck out on the water, do not attempt to swing to get it back as it is very dangerous and difficult. A good way
to get your plane back, retrieve the stalled or capsized model plane with a fishing rod that equips a real. Tie a tennis
ball on at least 12 lb. string. Of course, retrieve the plane with a boat is the best.

Double check the balance point of your plane, refer to
the plane manual and make sure the C.G. position is
correct. To obtain this position first try moving the
receiver battery and then if needed, add some lead. The
step should be about 10mm (3/8
”
)after the C.G. Position.
