Even small changes in the balance point make large
changes in stability. For your first flights we
recommend using a balance point at the forward
end of the center of gravity {C.G.} range, this
location will provide the most stability. As your
comfort and skill increase slowly move the C.G. aft
to increase the control response.
Lay a strip of masking tape along the top of each
wing as shown. Make two marks on the tape one 5
1/2-inches, one 6 1/4-inches back from the leading
edge of the wing. Repeat on the other side of the
fuselage. These marks represent the limits of the
C.G. range.
Turn the aircraft upside down and support it from
between the two marks. Slide the battery pack to a
position where the plane will balance level to
slightly nose heavy. Mount the battery inside the
fuselage at the determined location. Install the on
off switch in a convenient location per the
manufactures instructions. Reinstall the wing and
check the C.G. again. If necessary add weight to the
nose or tail.
CONTROL THROWS
Double check all controls move in the proper
direction
With your radio on, center all trims and adjust the
clevises so all control surfaces are straight. Measure
the control surface movement at the widest part of
each surface. Use the servo horns and bell crank
holes to adjust the control throw. For your first
flights the control throws should be set to the
following:
Elevator 1/2-inch up / down
Rudder 1 ½- inch right / left
Aileron 1/4-inch up / down
MOTOR SET UP
Be sure the motor is properly broken in using the
manufacture instructions. Set the throttle throw to
shut the motor off when the trim is pulled down and
idles reliably with the trim up.
After the motor is set, run one tank of gas at full
throttle, measure how much time it takes to run the
tank dry.
CONGRADULATIONS
you are now ready for test
flights.
Before leaving for the field be sure your batteries
are fully charged and you have all the required
support equipment {fuel, starter, glow driver, etc.}.
Although the TIGER SHARK will fly well in wind,
wait for a nice day.
At the field have a helper hold the airplane,
following the radio manufactures instructions
perform a range check of the radio. Do this with the
motor off, start the motor and do it again.

EVERY TIME YOU GO TO FLY!
TRIMING BASIC FLIGHT
The TIGER SHARK is NOT a trainer. A true
aerobatic aircraft, it goes only where you point it
and will not recover to level flight without control
input. If you do not have high performance
experience seek the help of someone who does.
Line up on the center of the runway and slowly
open the throttle, using the rudder to maintain
directional control. Once the tail is up apply a little
up elevator and allow the plane to gently lift off the
runway. Keep the climb angle and turns shallow
