Flying Tips and Repairs
Control Horn Settings
The illustration shows the factory settings for the control
horns. Fly the aircraft at factory settings before making
changes.
After flying, you may choose to adjust the linkage positions
for the desired control response.
CAUTION:
When these are incorrectly connected
for the pilot’s skill level, unexpected aircraft
response to controls can result. This can cause damage
to the aircraft and personal injury.
Aileron Elevator Rudder
WARNING:
Always engage throttle cut before
approaching the aircraft.
Range Check your Radio System
Range check the radio system with the aircraft. Refer to
your specific transmitter instruction manual for range test
information.
Flying
We recommend flying your aircraft
outside in no greater
than moderate winds or inside in a large gymnasium.
Always avoid flying near houses, trees, wires and buildings.
You should also be careful to avoid flying in areas where
there are many people, such as busy parks, schoolyards
or soccer fields. Consult local laws and ordinances before
choosing a location to fly your aircraft.
Takeoff
Place the aircraft in position for takeoff (facing into the
wind if flying outdoors). Set dual rates to low position and
gradually increase the throttle to ¾ to full and steer with
the rudder. Pull back gently on the elevator and climb to
check trim. Once the trim is adjusted, begin exploring the
flight envelope of the aircraft.
Landing
Always land into the wind. During the flare, keep the wings
level and the aircraft pointed into the wind. Slowly lower
the throttle while easing back on the elevator to bring the
aircraft gently down on all three wheels.
NOTICE:
Always fully lower the throttle at touch down
when landing the aircraft to prevent damage to the
propeller and motor.
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.
Over-Current Protection (OCP)
The aircraft is equipped with over-current protection.
OCP protects the ESC from overheating and stops the
motors 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.
Repairs
Crash damage is not covered under warranty.
Repair this aircraft using foam-compatible CA 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.
Hand Launching
N
OTICE:
Hand Launching in AS3X mode is not
recommended as it may result in a crash. Always hand
launch in SAFE Mode.
• We recommend flying without landing gear when hand
launching.
• Always hand launch in SAFE mode, into the wind at
100% power, in high rates.
When hand launching in SAFE mode, the control unit
will immediately sense the force of the launch and will
automatically enable the Hand Launch Assist feature.
When this feature is active, the control unit will add up
elevator automatically so the aircraft climbs at a higher
angle for a few seconds. It will return to standard SAFE
mode shortly after launch.
Grip
We recommend holding the aircraft just behind the wings,
as shown.
Follow Through
Use an overhand throw and launch with wings level and
the nose of the model slightly upwards. Follow through
with your hand launch by pointing your fingers at the
airplane after the throw. Avoid an arcing throw which can
pull the nose down at release.
