WING SEATING

D 1 Apply 1/16" thick x 1/4" wide foam wing
seating tape to the turbine sides in the wing
saddle area to seal the wing/fuse joints

NOTE: An alternate method of sealing the
wing/fuse joint is to use 'silicone bathtub sealer"

This is an excellent method, used by many experts
because it results in a permanent and nearly

perfect wing saddle joint Briefly, the technique is
as follows 1. Cover the bottom of the wing center
section with waxed paper or plastic kitchen wrap
Pull out all wrinkles and tape it to the wing

2. Squeeze out a bead of silicone sealer onto the
wing saddle area and front of the inlets 3. Lay the
wing in the saddle and push down gently The
excess silicone sealer will squeeze out 4. Allow to
dry without disturbing for at least 24 hours
5. Remove the tape then remove the wing from

the saddle (leaving the waxed paper or plastic
wrap in place) 6. Gently pull the waxed paper or

plastic wrap away from the sealer 7. Using a new
single-edge razor blade, trim the sealer flush with

the turbine sides, and along the inside of the
fuselage

RE-INSTALL ENGINE & RADIO

D 1 Mount the radio switch in the fuselage near
former F5 and run a pushrod to the left outside of
the plane as shown on the plans NOTE: The
Great Planes Switch/Charge Mount is perfect for
this application.

D 2 Install the receiver in the right turbine bay
and hook everything up to it Wrap the receiver in

1/2" latex foam to protect it Scrap pieces of balsa

can be used to hold the receiver in place

D 3 Re-install the engine, propeller, spinner
and wheels Attach the wing to the fuselage
Check the operation of all controls to make sure
they operate smoothly

WE RECOMMEND THE

FOLLOWING CONTROL

SURFACE THROWS:

NOTE: Throws are measured at the
widest part of the control surface, with

full deflection of the transmitter stick.

Cut the control throw gauge out of the
wing plan and use it to set the following

throws:

LOW RATE HIGH RATE

ELEVATOR: 5/8" both ways 7/8" both ways

RUDDER: 1/2" both ways 3/4" both ways

AILERONS: 1/4" both ways 1/2" both ways

If your radio does not have "dual rates", we
recommend setting up for the "high rate" throws, or

slightly less

NOTE: These control surface "throws"
are approximate and provide a good
starting point for the first flights with

your F-15. You may wish to change the
throws s l i g h t l y to provide the

smoothness or quickness you prefer.

Due to the maneuverability of this

model and the high control surface

throws that it will handle, it might be a
good idea to use exponential type
control surface movements if your radio
is capable of this.

BALANCE YOUR MODEL

NOTE: This section is VERY important

and must not be omitted! A model that

is not properly balanced w i l l be

unstable and possibly unflyable.

D 1 Accurately mark the balance point on the
BOTTOM of the wing on both sides of the turbine

sides The balance range is shown on the plan
