ALWAYS
unplug the motor batteries fi rst.
ALWAYS
use a LiPo approved charger.
ALWAYS
set the charger’s output volts to match the battery
volts.
ALWAYS
charge a LiPo battery in a fi reproof location.
ALWAYS
charge through the “charge” lead.
ALWAYS
KEEP OUT OF THE REACH OF CHILDREN.
ALWAYS
remove the batteries from the plane after a crash.
Set them aside in a safe location for at least 20 minutes. If
the batteries are damaged in the crash they could catch
fi re. If the battery starts to swell, quickly move the battery
to a safe location, preferably outside. Place it in a bucket,
covering the battery with sand. Never use water to try and
put out a LiPo fi re.
NEVER
operate the motor in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
NEVER
touch the motor during or right after operation. The
motor may be HOT!
NEVER
switch off the transmitter with the motor batteries
plugged in.
NEVER
use a NiCd/NiMH peak charger to charge a LiPo
battery.
NEVER
charge in excess of 4.20v per cell unless the battery
is rated for a higher voltage.
NEVER
charge through the “discharge” lead.
NEVER
charge at currents greater than 1C unless the battery
is rated for a higher charge rate.
NEVER
trickle charge a LiPo battery.
NEVER
allow the battery temperature to exceed 150 degrees
F [65 C].
NEVER
disassemble or modify the pack wiring in any way
or puncture the cells.
NEVER
discharge below 2.7V per cell.
NEVER
place the battery or charger on combustible materials
or leave it unattended during charge or discharge.
NEVER
charge the batteries in the plane.
FLYING
The Ryan STA EP ARF is a great-fl ying sport model that fl ies
smoothly and predictably. However, it does not possess the
self-recovery characteristics of a primary R/C trainer and
should be fl own only by experienced R/C pilots.
CAUTION:
(THIS APPLIES TO ALL R/C AIRPLANES): If,
while fl ying, you notice an alarming or unusual sound such
as a low-pitched “buzz,” this may indicate control surface
fl utter.
Flutter occurs when a control surface (such as an
aileron or elevator) or a fl ying surface (such as a wing or
stab) rapidly vibrates up and down (thus causing the noise).
In extreme cases, if not detected immediately, fl utter can
actually cause the control surface to detach or the fl ying
surface to fail, thus causing loss of control followed by
an impending crash. If fl utter is detected, slow the model
immediately
and land as soon as safely possible. Identify
which surface fl uttered (so the problem may be resolved) by
checking all the servo grommets for deterioration or signs
of vibration. Make certain all pushrod linkages are secure
and free of play. If it fl uttered once, under similar circum-
stances it will probably fl utter again unless the problem is
fi xed. Some things which can cause fl utter are; Excessive
hinge gap; Not mounting control horns solidly; Poor fi t of
clevis pin in horn; Side-play of wire pushrods caused by
large bends; Excessive free play in servo gears; Insecure
servo mounting; and one of the most prevalent causes of
fl utter; Flying an over-powered model at excessive speeds.
Takeoff
Before taking off, see how the model handles on the ground
by doing a few practice runs at
low speeds
on the runway.
Hold “up” elevator to keep the tail wheel on the ground. If
necessary, adjust the tail wheel so the model will roll straight
down the runway.
Remember to takeoff into the wind. When you’re ready, point
the model straight down the runway, hold a bit of up elevator
to keep the tail on the ground to maintain tail wheel steering,
and then gradually advance the throttle. As the model gains
speed, decrease up elevator allowing the tail to come off the
ground. One of the most important things to remember with
a tail dragger is to always be ready to apply
right
rudder to
counteract motor torque. Gain as much speed as your runway
and fl ying site will practically allow before gently applying up
elevator, lifting the model into the air. At this moment it is likely
that you will need to apply more right rudder to counteract
motor torque. Be smooth on the elevator stick, allowing the
model to establish a
gentle
climb to a safe altitude before
turning into the traffi c pattern.
