Range Test
Prior to your first flight you will need to do
a range test. Two people are needed to do
this–one to hold the transmitter and one to
hold the airplane.
1. One person holds the transmitter while
the other person walks 100 paces away
with the airplane.
2. Be sure the throttle slider is in the "OFF"
position.
2. Extend the transmitter antenna completely
and turn on the transmitter.
3. Plug in the airplane battery and close
the hatch cover.
4. As soon as the throttle is advanced, the
props should spin quickly.
5. As the first person moves both of the
transmitter controls in all directions,
the other person watches to be sure
the airplane’s motor and tail controls
operate smoothly.
If your plane does not range test correctly,
do not fly! Call Horizon Hobby Product
Support Staff toll-free at 1-877-504-0233 for
directions on how to proceed.
WARNING: The person holding the air-
plane should hold it so that the propeller
does not come near any part of their body.

Your Firebird Freedom
™
comes equipped
with exclusive Anti-Crash Technology.
™
This
software helps prevent crashes due to over-
control by pilots. The sensors included in
the fuselage “see” the horizon. One sensor
is above the canopy and faces forward. The
other is at the bottom of the fuselage and
faces backward.
The electronic system connected to them
knows the airplane should not be allowed
to enter a steep dive. If you give transmitter
input that causes the plane to enter into a
spiral dive that may threaten your aircraft,
the ACT software will override your input to
help prevent the aircraft from crashing to
the ground. The ACT will intervene for you
when the aircraft is in jeopardy by reducing
throttle and adding some up elevator, as
well. This causes the nose of the airplane
to pull up, thereby helping to prevent your
Firebird Freedom from crashing, provided
there is enough altitude for recovery. The
ACT software will only interrupt flight in
extreme situations, allowing you to enjoy as
much control of the airplane as you need.
