FLIGHT SETUP

Because transmitters other than the Tactic transmitters
may be used, the following information is included to
properly set the throws and C.G. (center-of-gravity) on
the AirCore Principle.

The measurements are taken at the widest part of the

control surface.

Rudder Throw 1/4 in [6 mm] 24 deg. Left and Right
Elevator Throw 9/32 in [ 7mm ] 15 deg. Up and Down

CG Location on the Wing 1-1/8" [29mm] – 1-5/16" [33mm]

from the leading edge, on the bottom of the wing.

OPTIONAL INSTALLATION
OF THE LANDING GEAR

RANGE CHECK

With the transmitter switched on and the battery plugged

into the AirCore Module, walk 50' [15 m] from the aircraft
and check the control functions for proper and smooth
operation.

FLYING THE AIRCORE AIRPLANES

Take off (or hand launch) directly into the wind.

Hand launch with throttle set at ½ power, wings level and
with a slight toss (it is not necessary to aggressively throw
this model to hand launch it).

Once in the air, gain altitude to allow yourself suffi cient
reaction time to make a correction during fl ight. The AirCore

Principle fl ies well at half throttle.

Once you’re comfortable, adjust the elevator and rudder
trims one click at a time so that the AirCore Principle
fl ies straight and level with the control sticks centered.

The airplane requires only small amounts of control stick

movement to fl y smoothly.

It’s recommended that you attempt to land before the motor
loses power and doesn’t have enough voltage to maintain
altitude. If you have a timer on your transmitter, set it for

4-minutes for the fi rst couple of fl ights. Then, gradually

increase the fl ight time to fi t your fl ying style. Allow at
least an extra 1-minute of fl ight time to allow for a second
attempt at landing.

If possible, always land directly into the wind.

Gradually reduce power when you are close to the landing

spot. When close to the ground and about to touch down,
pull the elevator stick back slightly to raise the nose of the
model and slow the landing speed to “fl air” for landing.

Unplug and remove the battery from the model and

switch off the transmitter. Allow the motor to cool
between flights.
