Flying
For the initial flights the UMX Extra 300 3D should
be flown in a gymnasium or large open space.
If flown outdoors, fly only in an open yard or
driveway and in VERY low winds. 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.
Set all control surfaces at
low rate
. Place the UMX
Extra 300 3D in position for takeoff (facing into the
wind, if outdoors). Gradually increase the throttle to
¾ to full, and steer with the rudder. Pull back gently
with the elevator and climb to check trim. Once the
trim is adjusted, begin exploring the flight envelope
of the UMX Extra 300 3D.
Note
: Always fully lower the
throttle when the aircraft lands
to prevent damage to the ESC.
Note
: Crash damage is not
covered under warranty.
Heat, direct sunlight or crash
damage can wrinkle the film
covering on the aircraft. This
will not decrease aircraft
performance.
Repairs
Thanks to the construction of the UMX Extra 300
3D, repairs to the foam can be made using foam-
safe CA or tape. When parts are not repairable, see
the Replacement Parts List for ordering by item
number.
Always
decrease throttle at
propeller strike.
We recommend using a DSM2 radio capable of
dual rates and expo. Adjust according to individual
preferences after initial flight. The DX5e transmitter
is not recommended.
NOTICE:
DO NOT SET YOUR TRANSMITTER ATV
OVER 100%. If the ATV is set over 100% it will
not result in more control movement, and it will
overdrive the servo and cause damage.
CAUTION
: Pushrod connections on control
horns directly affect aircraft response.
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.
