46) Make additional holes in the cowling as needed for your muffler
and to access the engine's needle valve.
RECEIVER BATTERY PACK
Both glow engine and electric motor users resume assembly here.

47) RECEIVER BATTERY PACK
a)
If you are using a receiver battery pack (all glow and some non-
BEC electric motor installations) wrap the battery pack with a
single layer of 1/2” thick soft foam rubber to insulate it from
vibration and shock. Use tape or rubber bands to hold the foam
around the battery.
b)
For now, leave the receiver battery pack loose on the bottom of
the fuselage in front of the servos. Later, when the Center of
Gravity (CG) is established, the final position of the battery pack
will be determined.
INSTALL SIDE WINDOWS
❑
48) From the kit contents, locate the bag containing the molded
clear plastic side windows. The clear windows are molded to fit
into the fuselage window frames from the inside. Note that
each window has a flange all the way around the outside
perimeter to provide an easy gluing surface. You may need to
trim the flanges a little closer than the factory did, in order to fit
them in place. A sharp scissors or snips works best for trimming
the windows.
Glue the windows in place with 5-minute epoxy or RC-56 type
glue.
Do not
use CA glue because it can cloud the plastic. Apply
a thin bead of glue around the edge of the window and press the
window in place from the inside of the fuselage. Don’t use too
much glue or it may ooze out onto the outside surface of the
window. Use a few small pieces of low tack tape to hold the
window in place until the glue dries.
CONGRATULATIONS!
Your RASCAL 80 EG ARF is completely assembled. However, it is NOT
ready for flight! There are a few very critical pre-flight tasks we must
perform before flying. These are extremely important and should be
approached with patience and care.
BALANCE YOUR AIRPLANE
This may be the single most important step in preparing your airplane
for flight. All airplanes, model or full-size, must be accurately balanced
in order to fly successfully. An airplane that is not properly balanced
will be unstable and will most likely crash.
NOT ALL RASCALS WILL BALANCE THE SAME
It is impossible to produce a model airplane kit that will automatically
have the correct balance point. Not everyone uses the same
engine/motor or radio gear - and all those items can vary in weight!
You might be surprised to know that .46 size 2-stroke R/C engines can
vary in weight from 11 oz. to 18 oz. - that’s almost a half-pound
difference, way out on the nose of your model! There can even be as
much as a 3/4 oz. difference in weight between different brands of
propellers! So, that’s why every model must be balanced before flying.
Don’t feel that whatever the balance point your model came out at is
“good enough”. Check carefully and make whatever adjustments are
required. Trying to fly an out of balance model is dangerous!
Preliminary: All the parts and components that will be in the airplane
in flight must be installed in their correct positions. This includes all the
radio gear, the propeller, spinner, muffler (if applicable), etc. Every
piece of essential equipment must be installed, ready for flight. Always
balance a glow powered model with the fuel tank empty. Always
balance an electric powered model with the battery pack in place.
