Step 5

The correct center of gravity (CG) sits approximately 6 inch-
es (15.25cm) in front of the trailing edge of the elevons and
is based on using the ParkZone 3S 2200mAh Li-Po battery
(PKZ1030). Molded round holes in each side of the finger
holds on the bottom of the plane mark the correct
CG location.
Whatever 3S Li-Po battery you choose, the CG should be
correct, provided you insert it correctly into the molded bat-

tery saddle. In order to avoid any problems, always double-
check the CG when using a different size battery from
the one you previously used. Also, any battery you choose
should fit snuggly into the foam saddle to prevent the CG
from shifting in flight.

Step 6

Prior to each flight, range check the radio system to make
certain everything is functioning correctly. To do this:

• Make certain that no one is using the channel you will be
flying on.
• Always make sure the transmitter is on prior to
plugging in the flight battery, and when you have
finished flying, the transmitter is turned off after the bat-
tery has been unplugged.
• Have someone help you with your range check. One
person needs to carefully hold the aircraft while the other
walks approximately 100 feet (30 meters) away.
Make certain the person holding the plane stays
clear of the propeller.

• With the radio on and the battery plugged in, the person
with the transmitter needs to turn the motor on and off,
and move the elevons up and down, to ensure the plane
functions properly and is receiving a strong signal from
the transmitter. Make certain the aircraft is responding
correctly to all input. If the aircraft does not respond
properly to every control command,

DO NOT FLY. Call the

Horizon Hobby Product Support Team at:
1-877-504-0233 (M – F, 8 a.m. to 7 p.m. CST).
• Prior to each flight, always make sure all controls
are functioning per the transmitter input.
• Always make sure you have fully charged
transmitter batteries.

Step 7

As stated in the beginning of this instruction manual, we
recommend you only fly the F-27C Stryker PNP at an AMA
sanctioned flying field. This airplane covers ground at more
than 80 mph (129 kilometers/hour) – that’s 117.3 feet per
second or 35.8 meters per second. Make certain no one is
flying on the same frequency before you take flight.
1. Always launch your aircraft directly into the wind, with a
very slight upward angle.
2. We recommend launching with power off, and then add-
ing between 60% and full throttle. This is due to the fact
that the F-27C Stryker PNP has a pusher propeller, and if
you are not careful you could cut your finger(s).

3. Do not fly the F-27C Stryker PNP at full throttle for the
duration of your flight. This may cause permanent dam-
age to your Li-Po battery and/or ESC.
4. After several minutes of flying, (approximately 6-10)
and when you begin to feel the power decreasing, it is
time to land.
5. Line up the aircraft directly into the wind when landing,
making sure you land with no power to the motor. This
will avoid causing damage to the prop, motor, and other
components of the plane.
