The wing struts on the RASCAL 110 are functional, and the
airplane should never be flown without the struts in place. The
struts mount to the wing and fuselage with M4 x 20mm
socket-head bolts. A metric 2.5mm ball driver is the best tool to
have for installation and removal. Do not be tempted to use an
S.A.E. 3/32" hex driver. This tool will eventually roach out the
bolt heads.
The wing struts are factory painted and already set-up to mate
with the appropriate blind mounting nuts that are pre-installed in
the fuselage sides and in the bottom surfaces of both wing
panels. There is a left and a right wing strut - note the airfoil
shape of each strut.
Assemble the two wing panels together, and then bolt the wing
on the fuselage with the M6.5 x 45 mm nylon wing bolts. Hold
the strut in place against the fuselage side and bottom of the
wing panel and install the bolts, starting the threads with your
fingers. Tighten the bolts in place firmly with a hex driver.
CONGRATULATIONS!
Your RASCAL 110 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
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.
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 or gas
powered model with the fuel tank empty. Always balance an
electric powered model with the battery pack in place.
RECOMMENDED STARTING BALANCE POINT
4-1/2" Behind The Leading Edge Of The Wing
The recommended starting balance point for the RASCAL 110
EG ARF, is located 4-1/2" behind the leading edge of the wing,
immediately next to the fuselage side. This is the location of the
main wing spars. We've flown this airplane with the C.G.
location as far back as 5" without any trouble. However, moving
the C.G. further back tends to make the elevators more
sensitive and will also accelerate the stall.
Because of its large size, balancing the RASCAL 110 using a
typical balancing fixture may not be practical. However, you can
get acceptably accurate results by first placing a piece of tape,
temporarily, on each side of the fuselage, just beneath the wing,
at the 4-1/2" location. Then, simply use your fingers beneath
each wing panel to pick the model up at the C.G. location.
Another method is for you and a friend to pick the model up at
the wingtips, at the main spar location.
The goal is to get the airplane to balance perfectly level at the
desired C.G. point. Level means level - not nose down or tail
down - level! If the nose hangs down, the model is nose heavy.
Likewise, if the airplane hangs tail down, it is tail heavy. If either
of these conditions exist with your model, they must be
corrected.
CONTROL SURFACE TRAVEL
Double check the alignment and movement of all the controls
one more time! Adjust all of your pushrod linkages so that the
control surfaces are in their neutral position when the
transmitter sticks and trim levers are centered. Make sure the
control surfaces move in the proper direction when you move
the sticks. You’d be amazed to know how many models have
been destroyed on takeoff with one of the controls reversed.
Don’t let it happen to you! In fact, it’s a good idea to get into the
habit of checking for proper control response every time you get
ready to fly.
Adjust your pushrod linkages and/or transmitter EPA (End
Point Adjustment) settings as necessary to provide the
recommended amount of control surface travel. NOTE: The
rudder measurement is taken from the bottom of the rudder, at
its widest point.
The following Low Rate control surface movements will provide
your RASCAL 110 EG ARF with smooth, predictable flight
characteristics. We suggest that you start with these Low Rate
movements and adjust them later to suit your style of flying.
Note that the rudder and elevator measurements are taken from
the widest part of the surface at the trailing edge. The aileron
measurements are taken at the inboard trailing edge. We have
also provided the High Rate settings that we use with our
RASCAL models. As you become familiar with flying your RAS-
CAL, these settings can be adjusted to suit your flying style.
RECOMMENDED CONTROL SURFACE TRAVEL
AILERONS - LOW RATE: 1-1/16" UP - 1-1/16" DOWN
HIGH RATE: 1-3/8" UP - 1-3/8" DOWN
ELEVATOR - LOW RATE: 1-3/16" UP - 1-3/16" DOWN
HIGH RATE: 1-5/8" UP - 1-5/8" DOWN
RUDDER -
LOW RATE: 1-3/4" LEFT - 1-3/4" RIGHT
HIGH RATE: SAME
RECOMMENDED FLAP SETTINGS
FULL FLAP: 2" down travel with 20% down elevator mix
HALF FLAP: 1" down travel with 11% down elevator mix
Make sure that both flaps travel evenly up and down at the
same rate and stop at the same position.
