Hand-Launch
Until you have become effi cient at fl ying your Cessna, always
use an assistant to hand-launch your model.
Have your assistant hold the model by the bottom of the
fuselage. When both of you have signaled “ready,” advance
the throttle to full power. Your assistant should run a few
steps with the plane held high above his head, and then give
the model a swift, but controlled toss at a level, or slightly
nose-up attitude. Initially, the model will gently ascend, but
within a few seconds it will reach enough speed to climb.
Gently add “up” elevator to establish the climb.
Once you have reached a safe fl ying speed at a comfortable
altitude (approximately 50’ [15m]), work the controls as
necessary to establish a gentle turn away from the runway.
Flying
One thing to remember is that, when the plane is fl ying away
from you, moving the aileron stick to the right will make
the plane bank to your right. However, when the model is
fl ying toward you, moving the aileron stick to the right will
make the plane move to your left. Of course, the plane is
still responding the same way, it’s just that your orientation
has reversed. This must be kept in mind while learning to
fl y (and is also a good reason to take fl ight lessons from an
experienced pilot!).
To establish a turn, “up” elevator (pulling back on the stick)
is usually required along with aileron input to get the model
into a bank. To stop the turn, apply a small amount of
opposite aileron.
Once you get the plane into the air and have climbed to a
comfortable altitude, the fi rst “order of business” will be to
“trim” the model for straight-and-level fl ight. The model fl ies
best at approximately 3/4-throttle. Adjust the trims on the
transmitter to make minor control surface adjustments as
necessary until the plane will fl y straight without any control
inputs. Often, your assistant can reach over and adjust the
trims for you.
Remember to keep the model high enough to give yourself
time to make corrections, but don’t let it get too far away.
Otherwise, it will be diffi cult to detect its attitude and which
way it is going.
One fi nal check before landing: see how the model will react
when it’s time to land and you cut the power. To do this,
while still at altitude, cut the motor power. The model should
establish a gentle, downward glide path. This is how the
model will react when it’s actually time to land. Add power
and climb back up to your original altitude. Try again, this
time adding fl aps. To climb, add throttle and immediately take
the fl aps back out.
Practice a few of these “climb and glides” to judge how far
out you will need to be when its time to land.
Landing
To land, fl y down-wind past the landing area. Gently turn
into the wind, add fl aps and reduce the throttle so that the
airplane initiates an ascending glide path. If necessary,
add power to extend the glide path to reach the runway.
As the model approaches and loses altitude, gradually and
proportionally add “up” elevator to control the glide path and
altitude. Continue to apply elevator until the model touches
down at which time you should be holding full, or nearly full
up elevator. This will cause the airplane to slow and settle to
the ground.
Later, once you have become more experienced with your
Cessna, you can cruise around and perform slow “fl y-bys”
with the fl aps extended.
CAUTION: If, during a rough landing, the propeller
becomes jammed and cannot rotate, the battery and
speed control will become very hot if you attempt to
add power. Immediately move the throttle down to
stop the motor. If you fail to do this, the motor, speed
control and/or battery will be damaged.
AFTER FLIGHT
Disconnect the battery and remove it from the airplane.
Then, turn off the transmitter. Allow the battery to cool before
recharging, or allow the motor to cool before installing another
battery for the next fl ight. Inspect the airplane to make sure
nothing has become loose or damaged.
