If you've carefully followed these assembly instructions, test fly-
ing your new RASCAL 110 should be a lot of fun! You will find
that the RASCAL 110 is a very smooth flying airplane. The sur-
face movements given in this manual should provide the air-
plane with smooth, positive control in pitch, roll, and yaw. We
found this to be true at virtually any speed that we flew the air-
plane. The controls will remain effective down to virtually zero
airspeed. We have found that coordinated turns - using both
ailerons and rudder - aren't necessary with this airplane. The
ailerons are effective and get the airplane around just fine.
However, using a little rudder in the turns is also very effective
and tends to bring the airplane around even quicker.
Make it a routine part of your pre-flight procedures to check
each control on the airplane, making sure each flight surface
moves in the correct direction. Also, check each control linkage
to be sure they are secure and that nothing is loose. Next,
make a routine range check with your radio system to be sure
that it is working perfectly. We always suggest that this same
range check be made when the engine is running. This is espe-
cially true if your airplane is powered with a gasoline engine.
Gas engines can often produce extraneous RF (radio frequen-
cy) "noise" while running. RF noise can interfere with the radio
system, causing servos to "glitch". If this occurs with your
model, take steps to eliminate the problem before trying to fly
the airplane.
When you're satisfied that the airplane is ready for flight, start
the engine and allow it to warm-up to operating temperature.
Holding up elevator, taxi the RASCAL out to the take-off posi-
tion on the flying field. For take-off, the airplane should be lined-
up with the center of the runway, with the nose pointed directly
into the wind. Hold a little up elevator and smoothly advance
the throttle - do not slam the throttle full open all at once. As the
airplane begins moving forward, gradually back off of the up ele-
vator input, using the rudder, only sparingly, to correct any
engine torque and/or wind induced deviations from a straight
take-off run. Allow the tail to come up and the airplane to gath-
er speed on the main wheels. Lift-off will happen shortly. Keep
the wings level with the ailerons and climb out at a shallow
angle to a reasonable trim altitude. At altitude, make any nec-
essary trim adjustments to achieve straight and level flight.
First, try a simple loop from level flight. You should see the air-
plane track cleanly through the loop with no tendency to "twist
out" at the top.
While still at altitude, fly the airplane into the wind and throttle
the engine back to idle. Keep the airplane level with the ailerons
and hold the nose up with elevator input. Watch carefully to
observe the stall characteristics of the model. Our RASCAL
110 models have all exhibited a consistently gentle stall, with
the wings barely rocking in pre-stall, followed by the nose drop-
ping just a little before the airplane almost immediately resumed
controlled flight. This exercise tells you a lot about how slow you
can fly the airplane during a landing approach.
The RASCAL 110 was never intended to be an IMAC capable
model but it can perform a surprising number of maneuvers,
and it does them all in majestic style. With the controls set at
