reduce the ground speed that must be reached and automatically provide “ heading assist ” making steering
and takeoff easier. Slowly advance the throttle, adding rudder correction as needed to keep the model rolling
straight. When the plane become “ light ”continue to apply throttle until you are at full power all this will happen
in a few seconds. When sufficient liftoff speed has been reached, gradually apply “up ”elevator allowing the
model to leave the ground. Do not “ yank ” up on the stick rather, be smooth and allow the plane to establish a
gentle climb.

Once you have reached a safe flying speed at a comfortable altitude (approximately 50’ [15m]), work the
controls as necessary to establish a gentle turn away from the runway.

Hand-Launch
!
!
Until you have become efficient at flying your plane, 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 flying 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 flying away from you, moving the aileron stick to the right will
make the plane bank to your right.
However, when the model is flying 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 fly (and is also a good reason to take flight 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 first “order of business” will
be to “trim” the model for straight - and - level flight. The model flies best at approximately 3/4-throttle. Adjust
the trims on the transmitter to make minor control surface adjustments as necessary until the plane will fly
!
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 difficult to detect its attitude and which way it is going.
!
!
One final 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 flaps.
!
!
To climb, add throttle and immediately take the flaps 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.
