SIG CAP 231EX, Инструкция по сборке, Страница: 23 / 26

Holding up elevator, taxi the model to get a feel for how it handles
on the ground. Make sure you have positive left and right turning
ability. If not, make any adjustments needed to achieve positive
ground control. Once you are satisfied with the taxi tests, line the
model up with the centerline of the runway, nose into the wind.
Hold a little up elevator and advance the throttle smoothly - do not
run the throttle up all at once! The airplane should roll forward
smoothly, tailwheel on the ground. As speed builds, slowly back off
the elevators and use just a little rudder, only as needed, to
maintain a straight takeoff run. The tail will come up as flying
speed is reached and a little up elevator will lift the CAP off the
ground.
Maintain a straight outbound flight path, climbing at a shallow
angle until a safe maneuvering altitude is reached. If the model
requires trim, fly it to a reasonable altitude first before trimming.
Initially, make your control inputs smooth and avoid jerking the
sticks.
At altitude, make any trim changes needed to achieve hands off,
straight and level flight. From our experience, this will take very
little trim input, if the model was assembled and balanced
according to this manual. Once you're comfortable, make a few
circuits around the field to get the feel of the controls. The airplane
should demonstrate smooth flight characteristics without
jumpiness or over-sensitivity.
At altitude, try a roll. Then try
another roll to the opposite side. Properly trimmed, the CAP will
roll smoothly and very axially in either direction. Now try a loop.
The CAP should pull cleanly through loops, without wandering to
either side. Once you're comfortable, try knife-edge flight. You will
quickly find that the CAP has little or no pitch/roll coupling and that
it easily maintains altitude with just a little rudder input! You will
also discover that your CAP has outstanding inverted flight
characteristics. Our prototypes require only the smallest amount
of down elevator to maintain level inverted flight!
Assuming you're comfortable and getting used to the airplane, take
it to a safe altitude and throttle back to get a feel for the slow flight
and stall characteristics. Properly balanced and trimmed, your
CAP should demonstrate fairly sedate, no fuss stall
characteristics. Once flying speed and up elevator input is bled off,
the CAP should just drop its nose and resume flying as speed
picks up. All of this is great information to have when you are
setting up the first landing.
Landing the CAP is a pleasure. We like to keep a little power on
the engine during final approach, down to a few feet off the ground.
We typically back completely off the throttle once the
airplane is low to the ground with a good rate of descent
established. Flair the airplane as the ground approaches for a
smooth 3-point landing and rollout.
Hard landings are not
necessary, sound piloting skills are.
The second flight should be even more fun because you have by
now inputted any required trims learned from the first flight. Before
flying again, check the airplane for anything that may have come
loose, become disconnected, etc. This is good practice and tends
to insure a long life for the model.
As you become more familiar with your CAP, you are going to
discover its ability to perform aerobatics. The CAP 231EX is an
elegant aerobatic machine with seemingly endless capabilities. As
mentioned earlier, you will quickly discover that your CAP has a
powerful rudder. If you want to, you'll find it fairly easy to make
climbing knife-edge passes at fairly low throttle settings. In fact, if
your radio has expotential capability on the rudder channel, you
may want to tone the rudder action down a little around center, to
suit your style of flying. For those of you interested in using your
CAP for 3-D aerobatics, set up your radio to take advantage of the
huge control movements available from this model. However, we
would urge you to "sneak up" on such control throws, making very
sure you have them available to you only on your high rate
switches!
We are sure that you will enjoy your CAP 231EX for a long time to
come. Please fly the model safely with constant regard to other
fliers, spectators, and property.
Good luck and good flying!
