APPLYING THE DECALS
❑
12)
Using a clean cloth, wipe the airframe down
completely to remove any dust and debris.
❑
13)
Working with one decal at a time, use a pair of
scissors and carefully cut out the decal along its outer
edges.
❑
14)
Remove the protective backing from the decal
and stick the decal to the airplane (use the photos on page
# 24 to position the decals). Lightly rub the decal with a
soft cloth to remove any trapped air from beneath it.
☛
If any air bubbles form in the decal you can "prick"
the bubble with a straight pin to release the air.
❑
15)
Repeat the steps above to install the remaining
decals. Rub each decal down thoroughly to adhere them
into place.
☛
If you have installed the optional landing gear, you
will need to use a modeling knife to cut a notch in the
front of the hatch cover so it does not interfere with the
nose gear strut.

BALANCING THE F-22 RAPTOR EP
❑
1)
It is critical that your airplane be balanced cor-
rectly. Improper balance will cause your airplane to either
perform poorly or to lose control and crash.
This location is recommended for initial test flying. The
C.G. can be moved fore or aft up to 1/4", but it is not
recommended that the C.G. be located any farther back
than 4-1/8" behind the leading edge of the wing, at the
fuselage sides.
The Center of Gravity is located 3-7/8"
back from the leading edge of the
wing, at the fuselage sides.
☛
The F-22 Raptor EP should be balanced with the flight
battery mounted in the cockpit.
❑
2)
Using a pencil, mark the location of the Center
of Gravity on both sides of the fuselage.
❑
3)
With the airplane right side up, place your fin-
gers on the two marks you drew and carefully lift the
airplane. If the nose of the airplane falls, the airplane is
nose heavy. To correct this, move the flight battery back
just far enough to bring the airplane into balance. If the
tail of the airplane falls, the airplane is tail heavy. To
correct this, move the flight battery forward just far
enough to bring the airplane into balance. When bal-
anced correctly, the airplane should sit level or slightly
nose down when you lift it up with your fingers.
☛
Once you have flown and become familiar with the
flight characteristics of the F-22 Raptor EP, the balance
point (C.G.) can be moved fore or aft up to 1/4" in each
direction to change the flight performance. Moving the
balance point back will cause the airplane to be more re-
sponsive, but less stable. Moving the balance point
forward will cause the airplane to be more stable, but less
responsive. Do not fly the F-22 Raptor EP beyond the
recommended balance range or an uncontrollable
crash could result!
CONTROL THROWS
❑
1)
We recommend setting up the F-22 Raptor EP us-
ing the control throws listed below. We list control throw
recommendations for both test flying and sport flying (on
next page). Use the test flying settings for your initial flights.
TEST FLYING
Pitch:
3/8" up
3/8" down
Roll:
1/2" up
1/2" down
The stabilators are coupled so that they produce both
pitch control (elevator) and roll control (ailerons).
These are referred to as "tailerons".
The control throws should be measured
at the LEADING EDGE of the stabilators.
Do not measure from the trailing edge.
IMPORTANT
Before setting the control throws you must set the
stabilator neutral point. To set the neutral point the
leading edge of each stabilator should be 1/8" below
the mold line on the fuselage. All control throws should
be measured from the stabilator neutral point.
