MOUNTING THE WINDSHIELD:
Packaged with the windshield is a small plastic bag containing six
T2 x 8 mm PWA screws.

Note that the windshield has been 

pre-drilled with six mounting holes. Fit the windshield in place onto
the top front of the fuselage.

Use pieces of tape to hold the

windshield firmly in place, without covering the mounting holes.
Use a 1/32" bit to drill six pilot holes through the pre-drilled holes
in the windshield and into the fuselage. Remove the windshield
and carefully apply a single small drop of this CA glue into each
drilled pilot hole.

Install the windshield in place using the six

mounting screws.

DECAL APPLICATION:
The decals supplied with the Seniorita EP ARF are printed on
Mylar

®

with an aggressive adhesive on the back side. They are not

water slide type decals. These decals are not die-cut and must be
removed from the carrier sheet using a hobby knife with a sharp
#11 blade and/or scissors.

The smaller decals can be easily applied to the model by simply
removing the paper backing sheet, and then, carefully laying the
decal in position and pressing it in place with your finger. However,
for the larger decals, such as the "SENIORITA EP" wing decal, we
suggest the following method of application.

Carefully cut out the decal and lift it off of the sheet with tweezers.
Use a product such as SIG Pure Magic Model Airplane Cleaner or
Windex

®

to spray the wing panel where the decal will be applied.

Then, spray the adhesive side of the decal itself. Lightly position
the decal in place onto the wing panel. The liquid cleaner allows
the decal to slide easily into the desired position - do not press
down on the decal. Once in position, hold the decal lightly in place
with your finger and use a paper towel to gently dab the excess
liquid away. Use a small squeegee to now set the decal in place,
removing all excess liquid and any trapped air bubbles. The SIG
4" Epoxy Spreader - #SIGSH678 - is perfect for this job. Mop up
any excess cleaner with a dry cloth and allow the decals to set 

overnight. They will be solidly adhered to the model without any
air bubbles.

CONTROL SURFACE TRAVEL:
The maximum distance that a control surface moves when you
move the transmitter stick to full deflection is called the "control
throw" or "control travel". This determines how responsive the
airplane will be to your control inputs. We suggest the following
control movements for beginning R/C pilots.

Ailerons:

3/4" (19 mm) up - 3/4" down

Elevator:

5/8" (16 mm) up - 5/8" down

Rudder:

1" (25 mm) left - 1" right 

Note: These measurements are always taken at the widest part of the control surface,

at the trailing edge.

Adjust these throws as mechanically close as possible by trying
different connection points for the pushrods at the control horns. It
is best to start out in the outer holes of the servo output arms and
the outer holes of the control horns. If you have too much surface
throw or movement with the pushrods in these outer holes, move
in one hole at the servo output arm. If you need more throw, move
the RC link in one hole at the control horn. With a computer type
transmitter that has an EPA (End Point Adjustment) feature, the
adjustment and fine-tuning of the flight control servos becomes
much more easy to adjust.

Always set the transmitter control

movements at 100% before making any mechanical adjustments.

CENTER OF GRAVITY:
Establishing the correct Center of Gravity (C.G.) on this or any
other R/C model airplane is critical to its ultimate success in the
air.

The recommended starting balance point for the Kadet

Seniorita EP ARF is located at 3-1/4" (82.5 mm) behind the
leading edge of the wing. This is the location of the main wing
spar. We do not recommend trying to fly this model with a C.G.
further back than this location, as it is likely to make the elevator
(pitch control) very sensitive. IMPORTANT: You should always
balance the model with your flight battery installed. It is a simple
matter to shift the battery pack fore or aft to adjust the balance
point as needed.

A simple balancing fixture, such as two dowels with rubber tips to
protect the finish, is the most accurate method for determining and
then, adjusting the correct C.G. location.

As shown, use two

pieces of tape on the side of the fuselage, just beneath the wing,
to mark the 3-1/4" C.G. point. Later, after balancing the airplane,
the tape can be removed.

If you don't have a balancing fixture, enlist a friend to pick up the
airplane at one wingtip while you support the other, using the main
