Trimming the Aircraft

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 in flight while the sticks are at
neutral (centered) and the throttle is at 50% in AS3X flight
mode, adjust the trim to compensate:
• Up trim to stop down drift
• Down trim to stop up drift
• Left trim to stop right drift and roll
• Right trim 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 in no wind, 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 aircraft 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.

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 10mph 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 7 minutes.
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
when in AS3X flight mode.
Direction of Drift
Landing
Always land into the wind. Reduce throttle to zero and
allow the aircraft to settle into a glide path. During landing
approach keep the wings level and the aircraft pointed into
the wind. As the aircraft settles close to the ground, ease
back on the elevator to flare for landing.
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 foam safe CA glue or clear tape.
When parts are not repairable, see the Replacement Parts
List for ordering by item number.
