We recommend fl ying your E-fl ite
®
UMX Carbon
Cub SS outside in no greater than moderate winds
or inside in a large gymnasium. Always avoid fl ying
near houses, trees, wires and buildings. You should
also be careful to avoid fl ying in areas where there
are many people, such as busy parks, schoolyards
or soccer fi elds. Consult local laws and ordinances
before choosing a location to fl y your aircraft.
Takeoff
Place the Carbon Cub SS in
position for takeoff (facing into
the wind if fl ying outdoors).
Gradually increase the throttle
to full power, holding a small
amount of up elevator and
steering with the rudder. Climb
gently to check trim. Once the trim is adjusted,
begin exploring the fl ight envelope of the aircaft.
Landing
Make sure to land into the wind. Fly the aircraft to
approximately 6 inches (15 cm) or less above the
runway, using a small amount of throttle for the
entire descent. Keep the throttle on until the aircraft
is ready to fl are. During fl are, keep the wings level
and the aircraft pointed into the wind. Gently lower
the throttle while pulling back on the elevator to
bring the aircraft down on all three wheels.
Flaps
Due to the pitching up nature of fl aps, do not
activate the fl aps at high throttle settings. Apply the
fl aps when on fi nal approach. Fly the aircraft down
to approximately 6 inches (15 cm) or less above
the runway, using a small amount of throttle for the
entire descent. Keep the throttle on until the aircraft
is ready to fl are. During fl are, keep the wings level
and the aircraft pointed into the wind. Gently lower
the throttle while pulling back on the elevator to
bring the aircraft down on all three wheels.
If you need to abort the landing, move the fl aps to
their UP position before applying power to climb.
Failure to lower the throttle
stick and trim to the lowest
possible positions during a
crash could result in damage
to the ESC in the receiver
unit, which may require
replacement.
Over Current Protection
(OCP)
The Carbon Cub SS is
equipped with Over Current
Protection (OCP). OCP
protects the ESC from overheating and stops the
motor when the transmitter throttle is set too high
and the propeller cannot turn. OCP will only activate
when the throttle is positioned just above 1/2
throttle. After the ESC stops the motor, fully lower
the throttle to re-arm the ESC.
Takeoff and Landing on Water
To take off on water, steer with the rudder and
slowly increase the throttle. Keep the wings level
on takeoff. Hold a small amount (1/4–1/3) of up
elevator and the aircraft will lift off once fl ying speed
is reached. Avoid rapidly increasing the throttle as
torque from the motor may cause the aircraft to roll
to the left when on water.
To land the Carbon Cub SS on water, fl y the aircraft
to a couple of feet off the surface of the water.
Reduce throttle and add up elevator to fl are
the aircraft.
When taxiing, you must use some throttle to create
propeller blast over the rudder to steer, as there is
no water rudder.
Avoid taxiing cross wind if there is a breeze, as this
can cause the aircraft to fl ip over if the wind gets
under the upwind wing. Taxi 45 degrees into the
direction of the wind (not perpendicular to the wind)
and use aileron to hold the upwind wing down.
The aircraft will try to face into the wind when
taxiing. The wind naturally turns the aircraft to face
into the wind.
Repairs
Crash damage is not covered under warranty.
Repair this aircraft using foam-compatible CA
(cyanocrylate adhesive) glue or clear tape. Only use
foam-compatible CA glue as other types of glue can
damage the foam. When parts are not repairable,
see the Replacement Parts List for ordering by
item number.
For a listing of all replacement and optional parts,
refer to the list at the back of this manual.
NOTICE:
Use of foam-compatible CA accelerant on
your aircraft can damage paint. DO NOT handle the
aircraft until accelerant fully dries.
Flying Tips and Repairs
Always
decrease throttle at
propeller strike.
