Range Check your Radio System

After ﬁ nal assembly, range check the radio
system with the Ultra Micro Stryker. Refer to
your speciﬁ c transmitter instruction manual
for range test information.

CAUTION: Keep hands away from the

propeller. Always assume the motor is pow-
ered on and that the propeller blades may
turn at any time.

Launching

Always inspect and repair model before ﬂ ying.
Any damage or loose linkages may decrease
control in high-speed ﬂ ight.

CAUTION: Always launch the model

with the throttle set at 0% to avoid injury
from the propeller. When the model is
safely free of your hand, increase throttle to
between 60 and 100%.

Always launch your model at a very small
upward angle and directly into the wind,
even in a light breeze.

When launching your model for the ﬁ rst time,
set the dual rate in your transmitter to the low
rate position.

Hand Launching

To hand launch the Ultra Micro Stryker, hold
the airplane in the ﬁ nger grips on the under-
side of the airplane. Give a ﬁ rm throw directly
into the wind slightly up (5–10 degrees above
the horizon) with the throttle all the way
down and the propeller not spinning. After
release, when the propeller is clear of your
hands, add throttle to climb.

Flying

Only ﬂ y your Ultra Micro Stryker in light
winds. Always choose a wide-open space for
ﬂ ying your Ultra Micro Stryker. Always avoid
ﬂ ying near houses, trees, wires and buildings.
You should also be careful to avoid ﬂ ying
in areas where there are many people, such
as busy parks, schoolyards, or soccer ﬁ elds.
Consult local laws and ordinances before
choosing a location to ﬂ y your aircraft.

For your ﬁ rst ﬂ ights, set your transmitter timer
to 5 minutes. Adjust your timer for longer or
shorter ﬂ ights once you have ﬂ own the model.

Over Current Protection (OCP)

The UM F-27Q Stryker is equipped with Over
Current Protection (OCP). This feature protects
the ESC from overheating. OCP stops the
motor when the transmitter throttle is set
high and the propeller cannot turn. The OCP
will only activate when throttle is positioned
just above 1/2 throttle. After the ESC stops the
motor, fully lower the throttle to re-arm
the ESC.

Landing

Land the model when you notice a reduction
in power. If using a transmitter with a timer, set
the timer so you have enough ﬂ ight time to
make several landing approaches.

The model’s nose wheel and bottom ﬁ n skids
let the model land on hard surfaces when
needed (which may damage the propeller).
Align model directly into the wind and ﬂ y
down to the ground using 1/4 to 1/3 throttle
to keep enough energy for a proper ﬂ are.
Before the model touches down, always
fully decrease throttle to avoid damage to
propeller, motor, ESC or other components.

Failure to lower the throttle
stick and throttle trim to the
lowest possible positions
during a crash could result
in damage to the ESC in the
receiver unit.

NOTICE: Crash damage is not
covered under warranty.

Repairs

Repair the Ultra Micro Stryker using foam-
compatible CA (cyanocrylate adhesive) glue
or clear tape. Only use foam-compatible
CA, as other types of glue can damage the
foam. When parts are not repairable, see the
Replacement Parts List.

For a listing of all replacement and optional
parts, refer to the list at the back of
this manual.

NOTICE: Use of foam-compatible CA acceler-
ant on your model can damage paint. DO NOT
handle model until accelerant fully dries.
