Trimming the Aircraft
Flying
Consult local laws and ordinances before choosing a
location to fly your aircraft.
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
We recommend flying your aircraft outside in no greater
than very light winds or inside in a large gymnasium.
Always avoid flying near houses, trees, wires and buildings.
Avoid flying in areas where there are many people, such as
busy parks, schoolyards or soccer fields.
Set a timer for 7minutes.
Hand Launching
To hand launch the aircraft, hold the fuselage under the wings.
Advance to full throttle and give the aircraft a firm throw,
slightly up (5–10 degrees above the horizon), and directly into
the wind. After the model gains altitude and speed, decrease
the throttle and trim the aircraft for level flight.
Takeoff
Taxi the aircraft in position for takeoff (facing into the wind if
flying outdoors). Gradually increase the throttle to full power.
Hold a small amount of up elevator and steer with the rudder.
When the aircraft lifts off, climb gently and adjust the trim
for level flight. Once the trim is adjusted, begin exploring
the flight envelope of the aircraft. When your timer expires,
prepare for landing.
Landing
Always land into the wind. Fly the landing pattern with a
slightly nose high attitude. Use throttle management to
control the descent rate of the aircraft.
During 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 the
main wheels.
NOTICE: Always fully lower the throttle at touch down when
landing the aircraft. 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 or to the propeller shaft.
Crash damage is not covered under warranty.
Repairs
Repair this aircraft using CA glue or clear tape. When parts
are not repairable, see the Replacement Parts List for
ordering by item number.
Direction of Drift Button to Correct
Adjusting Trim in Flight
Familiarize yourself with your transmitter’s controls and
the aircraft’s response before flying by performing the
recommended Control Direction Test. Press the trim buttons
on your transmitter to adjust how the aircraft flies.
If the aircraft’s nose drifts while the sticks are at neutral
(centered) and the throttle is at 50%, press the trim buttons:
• Upper button to stop up drift
• Lower button to stop down drift
• Left button to stop right drift and roll
• Right button to stop left drift and roll
If you press a trim button until no beep sounds and the
aircraft does not fly straight and level, land and manually
adjust the trim as described below.
Manually Adjusting Trim
Only adjust trims in AS3X flight mode. Power on the model,
carefully hold the Night Vapor and advance the throttle for
prop to spin. Lower throttle to 0% and manually adjust
trims if needed.
Press the trim buttons to return to center (3 beeps will sound),
then use a pair of pliers to carefully adjust the metal U-bend on
the control rod of the surface requiring adjustment:
• Adjust the U-bend smaller for up elevator or right rudder.
• Widen the U-bend for down elevator or left rudder.
