Step 1

The throws that we recommend you set-up for low rate are:
Ailerons: +/- 7/16 inches (11mm)
Elevator: +/- 3/8 inches (9mm)

The throws that we recommend you set-up for high rate are:
Ailerons: +/- 5/8 inches (16mm)
Elevator: +/- 1/2 inches (12mm)
Note: When you are looking from the tail of the aircraft and

you give right aileron command, the right elevon should
deflect upward, while the left deflects downward
(and vice versa).

When pulling the elevator stick back, the elevons should both
deflect upward. When pushing the elevator stick forward, the
elevons should both deflect downward

Your F-27C Stryker PNP comes out of the box with the
E-flite 25A Brushless ESC. This controller has been designed
for use in radio control aircraft to handle up to 25 amps of
continuous motor current and up to 4 micro servos with a
2- to 3-cell Li-Po battery. It is suitable to use with most radio
brands. The ESC comes in an impressive plastic case with
exposed, finned heat sinks for both of the motor drive mosfets.
And, unlike many ESCs, it also has a finned heat sink fitted to
the BEC regulators to give a more reliable and potent power
supply to the servos. If you intend to fly your F-27C

Stryker

PNP stock, then there is no need to program the ESC. It comes
installed with the default settings for the installed motor. If you
intend to re-program the ESC, we strongly recommend remov-
ing the propeller first in order to avoid the propeller from spin-
ning if the motor is accidentally engaged.

Note: ALWAYS assume the motor and the propeller are
live. ALWAYS keep clear of the propeller at all times.
The high rpm of the brushless motor can cause
severe injury.

The E-flite 25-amp ESC has the following features:
• Two soft-cut settings (for 2- and 3-cell Li-Po battery packs)
• 70% Smart Cut feature
• Brake option
• Timing options for up to a 4-pole motor and
motors with more than 4-poles
• 2 setting options for the throttle input range

Using the E-flite 25A Brushless ESC:
The E-flite 25A Brushless ESC is very simple to use. It includes
a safety feature that will not arm the motor until the throttle
stick has been held in the Idle/Off position for more than one
second. When the battery is first connected, the ESC will indi-
cate what setting you have selected for the soft cut voltage
with a low, long beep followed by two or three medium length,
mid-tone beeps to indicate the cell count (7 beeps if 70%
Smart Cut is selected).

Note: Some computer radios may require the ATV to be
increased on the low end to arm the ESC. Try using incre-
ments of 5%, such as 105%, 110%, etc.

Also make sure the servo reversing switch on the Tx is set
at normal, or it will not arm.

To prepare for flight, turn on your transmitter and ensure the
throttle is set to the idle/OFF position. Next, plug in the flight
pack to the speed control and listen for the tones to indicate
soft cut voltage. After the controller has indicated the cell
count, the controller will make one set of 3 medium length,
rising tones to tell you it is armed and ready to fly, or 2 sets of
fast rising tones if you are entering the programming mode.

For your own safety, and the safety of others, you should always
treat the motor and propeller as though they are “live” and dan-
gerous, remembering that the motor could start at any time.
