Congratulations on your purchase of the HobbyZone®
Super Cub Floats. These floats add a new level of fun and
excitement to your Super Cub.
Note: Only use the floats if you are comfortable flying your Super Cub
and have repeatedly and successfully taken off, flown and landed.
Flying off water poses a higher risk to the airplane because the
electronics can fail if immersed in water.
Crash damage is not covered
under the warranty.
Be sure to read the warranty
on page 16 and "Warnings and
Safety" on pages 14–15 before
you proceed to Step 1.

Step 1
Assembly
• Remove contents from the box
and inspect for missing parts or
any damage.
• Separate the eight 3mm x 10mm
Phillips head machine screws, the
spreader wires and the two landing
gear legs.
• Note that there is a right and left
float. The indentions in the foam for
the spreader wires and landing gear
will face inward.
• Install the landing gear with the wider
top portion into the front holes on the
floats. Next install the front spreader
wire into the second holes on the
floats. Install the rear spreader wire
into the third holes on the floats.
Finally, install the rear landing gear
legs with the narrower top portion into
the rear holes on the floats.

Installation
• Install the eight 3mm x 10mm Phillips
head machine screws into the
floats making sure the screws are
tightening against the flat spots on
the wires.
• Install 10 x 8 propeller included with
the float kit*. Do not use the 9 x 6
prop included with the airplane as
there will not be enough power to
successfully fly on floats.
* When using the 10 x 8 propeller, it is
essential that you allow approximately
10–15 minutes between flights in order
to allow the 480 motor to properly cool.
Failure to follow this warning will greatly
reduce motor life.
• Remove the landing gear and
landing gear covers from your
Super Cub.
• Insert the front landing (wider) gear
wire of the floats into the front
landing gear slot.
• Insert the rear landing gear wire into
the rear float mount in the fuselage.
Rear Float
Mount
• The Super Cub LP (blue Super Cub
with Li-polymer battery) comes with
the rear float mount pre-installed in
the fuselage. If you are attaching
your Super Cub floats to an original
red Super Cub (HBZ7100), a rear float
mount will have to be installed into
the fuselage. This is a separate part
that has been included with this float
set. Please see page 9 for installation
instructions.

Success Tips
• Install the landing gear straps on the
rear float mount with the included
self-tapping screws.
Note: If installing the floats on the original
red and white Super Cub (HBZ7100),
refer to page 9 of this manual for
installation of the rear float mount.
Prior to each flight, make sure ACT is off
and never attempt to fly with the floats with
ACT on.
When flying with floats always take off
and land into the wind. Do not fly off
water when the wind is too high as the
wind causes larger waves and makes the
plane more likely to flip over.
Attempt your first float flight only if the
water is calm with very little wind. When
taxiing in the water always hold full up-
elevator. When starting your takeoff or
just after touchdown, hold up-elevator
to prevent the floats from “digging”
into the water and causing the plane to
flip over.
On takeoff when the floats begin to ride
on top of the water, or get “on step”,
reduce the up elevator input and allow
the plane to build up speed before
lifting off.
When flying off water there is usually a
lot of room to fly, do not try to force the
plane into the water. Let the airplane
settle into the water when landing. If a
float starts to “dig” into the water it will
cause the airplane to veer to one side or
the other. Reduce power immediately
and abort the takeoff.
The floats add weight well below the
airplane and cause a “pendulum” effect
that will change the flying characteristics
of the Super Cub.

9 10
When finished flying off water check all
components for water, if any water is in
the airplane or around the battery
cavity, dry with a paper towel.
Check for water inside the floats. The
joint between the plastic bottom surface
and the foam structure has been sealed,
but if for some reason that seal has
been broken, water could build up
inside the float. This could cause
serious weight gain and/or CG issues.
Installing Floats on the Red and White Super Cub
If installing floats on your red and white
Super Cub (HBZ7100), you will need to
install the included rear float mount on
the fuselage.
Note: We recommend you change the
receiver unit in your red and white
Super Cub to the receiver unit in the
Super Cub LP. You will also need to use
the 3S 11.1V Li-Po Battery (PKZ1033)
The ESC auto cut in the original Super
Cub has been set for Ni-MH cells and
can cause permanent damage to a Li-Po
battery pack if flown to the low-voltage
cutoff point.
Measure back 5 3/4 inches from the
rear of the slot for the original landing
gear. Place the front edge of the rear
float mount at this distance and press
the rear mount into the fuselage of your
Super Cub.
Note: The rounded corners will be facing
forward.
Success Tips (continued)

11 12
Press hard enough to leave marks in the
foam on the fuselage to indicate what
foam needs to be removed. Set the
rear mount aside, then slowly cut away
where the foam is compressed by the
rear float mount until the mount is flush
with the bottom of the fuselage.

13 14
Glue the rear float mount into the
fuselage using epoxy, making sure not
to get epoxy in the screw holes. Go to
the assembly and installation section
when done mounting the rear float
mount into your Super Cub.
Note: The rear float mount will rest on top of
the foam and not be recessed into the
bottom of the fuselage.
• Do not y off of water if you are
uncomfortable flying the Super Cub
on land. Only use the floats if you can
fly the Super Cub without having any
incidents and can take off and land
smoothly and multiple times in a row.
• Do not y in wind over 5–7 mph
(8-11km/h) as wind will cause larger
waves and make the plane more
susceptible to flipping over.
• Always stay clear of the propeller.
• Always select wide open spaces.
• Always follow all aircraft instructions
when using the floats.
• Always y your aircraft responsibly.
• Stay away from boat wake as it may
cause the airplane to flip or splash
water into the airplane and on the
electronics.
Warnings and Saftey
• Always check the bottom of the oats
each time you pull the airplane out
of the water to check if there is any
damage from hitting submerged
sticks or rocks. If water is found in a
float, it needs to be carefully
removed before the next flight.
• Never attempt to swim out to your
airplane in the water. Use a boat,
RC boat or fishing pole to retrieve
your airplane. Also be aware that
the airplane is still powered up when
retrieving it.
• Never retrieve the airplane alone.
Always have another person with you
to assist in retrieval.
• If the motor of the airplane gets
wet, do not power up to get the
airplane back to the shore. It is
possible to burn up the motor if it is
run while wet.

15 16
• Always allows 10-15 minutes for the
motor to cool between flights when
flying with the 10 x 8 propeller. The
Super Cub’s 480 motor may be
damaged if you don’t follow this
warning.
Prior to each flight, make sure ACT is off
and never attempt to fly with the floats with
ACT on.
Warnings and Saftey (continued)
The Super Cub Floats are guaranteed
against any manufacturing defects at
the time of production. There is no
warranty of any kind from damage to
either the aircraft or the floats itself due
to hard landings or crashes. If you have
any questions regarding your floats,
please contact the Horizon Service
Center at 1.877.504.0233
