SIG RASCAL ARF, Assembly Manual, Page: 12 / 18

RECOMMENDED INITIAL CONTROL MOVEMENTS:
RUDDER: 3/8” RIGHT, 3/8” LEFT
ELEVATORS: 1/4” UP, 1/4” DOWN
SIDE WINDOW INSTALLATION:
From the contents of your kit, locate the small bag containing the
molded side windows.
We suggest using 5-minute epoxy or
RC-56 glue to mount the windows into the inside of the fuselage.
DO NOT use thin CA glue for this step! Use scissors to cut out
each window, leaving about 1/8" of plastic around the edges for a
gluing surface. Apply a thin bead of glue to these edges and press
the window in place from the inside of the fuselage. Use small
pieces of tape to hold the windows in place until the glue sets. A
little alcohol will clean off any excess glue from the windows.
DECAL APPLICATION:
The decals supplied with the Rascal ARF kit are high quality Mylar
with an extremely aggressive adhesive. These are not die-cut and
must be cut from the sheet with a hobby knife and sharp #11 blade
or with sharp scissors.
We suggest the following method to accurately apply these decals.
Carefully cut out the decal with a hobby knife. Lift it carefully off its
sheet with tweezers. Use a product like SIG Pure Magic Model
Airplane Cleaner, Fantastic®, or Windex® to spray the area of the
model that will receive the decal. Then spray the adhesive side of
the decal as well. Lightly position the decal in place on the model.
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 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.
BALANCE:
IMPORTANT: The flight pack battery must be installed in the
fuselage and the propeller and spinner mounted in place to the
gearbox when determining the correct Center of Gravity (CG)
location.
The correct CG location for your ARF Rascal is located precisely
at the main spar location. This means that when you place your
fingers, one on each side of the bottom of the wing, at the main
spar location, the airplane must balance in a level position. If the
nose hangs low, the model is "nose heavy". If the tail hangs low,
this means the model is "tail heavy". If either of these conditions
exist, you must make adjustments to correct the problem. Never
attempt to fly your model in an out of balance condition. Since the
flight battery pack is the single heaviest component in the airplane,
it can be used to adjust almost any tail heavy or nose heavy
condition. This is simply done by positioning the battery pack
either forward or rearward on the battery hatch, as needed. In the
unlikely event this cannot correct the problem, then additional
stick-on type lead weights may be needed. These are available
from your local hobby shop.
PROPELLERS:
We have used and can recommend the APC 8 x 6E propeller for
this airplane. This propeller comes with its own set of adapter
rings, allowing it to fit perfectly onto the propeller shaft on the
gearbox. You might want to experiment with different propellers as
they can make a big difference in how your airplane flies. For best
performance, always carefully balance your propellers.
Note that the propeller shaft adapter on the gearbox assembly is
fitted with a 6-32 x 1/2" Allen head bolt. Some propellers with
thicker hubs may require a bolt length longer than 1/2". In this case
