the servo reversing in the transmitter to reverse the servos
connected to those controls. Be certain the control surfaces
have remained centered. Adjust if necessary.
SET THE CONTROL THROWS
Use a Great Planes AccuThrow
™
(or a ruler) to accurately
measure and set the control throw of each control surface
as indicated in the chart that follows. If your radio does not
have dual rates, we recommend setting the throws at the
low
rate setting.
NOTE
: The throws are measured at the
widest part
of
the elevators, rudder and ailerons. If you are using a ruler
to set your control surface throws, the defl ection distance
is measured as the height from the center trailing edge of
the control surface when moved from the neutral position as
shown in the sketch. Defl ection in degrees is also provided
for an alternative measuring method.
These are the recommended control surface throws:

IMPORTANT:
The Tiger 2 ARF has been
extensively
fl own and tested to arrive at the throws at which it fl ies
best. Flying your model at these throws will provide you
with the greatest chance for successful fi rst fl ights. If,
after you have become accustomed to the way the Tiger
2 fl ies, you would like to change the throws to suit your
taste, that is fi ne. However, too much control throw could
make the model diffi cult to control, so remember, “more
is not always better.”
BALANCE THE MODEL (C.G.)
More than any other factor, the
C.G.
(balance point)
can have the
greatest
effect on how a model fl ies, and
may determine whether or not your fi rst fl ight will be
successful. If you value this model and wish to enjoy it for
many fl ights,
DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE.
A model that is not properly balanced
will be unstable and possibly unfl yable.
At this stage the model should be in ready-to-fl y condition
with all of the systems in place including the engine or
brushless motor, landing gear, and the radio system (and
battery pack if applicable).
1. Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately
mark the C.G. on the top of the wing on both sides of the
fuselage. The C.G. is located 3-7/8" [98mm] back from the
leading edge of the wing.
This is where your model should balance for the fi rst
fl ights. Later, you may wish to experiment by shifting
the C.G. up to 3/8" [9.5mm] forward or 3/8" [9.5mm]
back to change the fl ying characteristics. Moving the
C.G. forward may improve the smoothness and stability,
but the model may then require more speed for takeoff
and make it more diffi cult to slow for landing. Moving
the C.G. aft makes the model more maneuverable, but
could also cause it to become too diffi cult to control. In
any case,
start at the recommended balance point
and do not at any time balance the model outside the
specifi ed range.
