Great Planes Big Stik 60 ARF MonoKote - GPMA1221 - Manual (Page 21)

The Big Stik ARF is a great-flying model that flies smoothly
and predictably. The Big Stik ARF does not, however,
possess the self-recovery characteristics of a primary R/C
trainer and should be flown only be experienced R/C pilots.
Before you get ready to take off, see how the model handles
on the ground by doing a few practice runs at low speeds
on the runway. If necessary, adjust the nose wheel so the
model will roll straight down the runway. If you need to calm
your nerves before the maiden flight, shut the engine down
and bring the model back into the pits. Top off the fuel, then
check all fasteners and control linkages for peace of mind.
Remember to take off into the wind. When you're ready,
point the model straight down the runway, then gradually
advance the throttle. Gain as much speed as your runway
and flying site will practically allow before gently applying up
elevator, lifting the model into the air. At this moment it is
likely that you will need to apply more right rudder to
counteract engine torque. Be smooth on the elevator stick,
allowing the model to establish a gentle climb to a safe
altitude before turning into the traffic pattern.
For reassurance and to keep an eye on other traffic, it is a
good idea to have an assistant on the flight line with you. Tell
him to remind you to throttle back once the plane gets to a
comfortable altitude. While full throttle is usually desirable for
takeoff, most models fly more smoothly at reduced speeds.
Take it easy with the Big Stik ARF for the first few flights,
gradually getting acquainted with it as you gain confidence.
Adjust the trims to maintain straight and level flight. After
flying around for a while and while still at a safe altitude with
plenty of fuel, practice slow flight and execute practice
landing approaches by reducing the throttle to see how the
model handles at slower speeds. Add power to see how she
climbs as well. Continue to fly around, executing various
maneuvers and making mental notes (or having your
assistant write them down) of what trim or C.G. changes
may be required to fine tune the model so it flies the way you
like. Mind your fuel level, but use this first flight to become
familiar with your model before landing.
To initiate a landing approach, lower the throttle while on the
downwind leg. Allow the nose of the model to pitch
downward to gradually bleed off altitude. Continue to lose
altitude, but maintain airspeed by keeping the nose down as
you turn onto the crosswind leg. Make your final turn toward
the runway (into the wind) keeping the nose down to
maintain airspeed and control. Level the attitude when the
model reaches the runway threshold, modulating the throttle
as necessary to maintain your glide path and airspeed. If
you are going to overshoot, smoothly advance the throttle
(always ready on the right rudder to counteract torque) and
climb out to make another attempt. When you're ready to
make your landing flare and the model is a foot or so off the
deck, smoothly increase up elevator until it gently touches
down. Once the model is on the runway and has lost flying
speed, hold up elevator to place the tail on the ground,
regaining tail wheel control.
One final note about flying your model. Have a goal or flight
plan in mind for every flight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know, or
learning how the model behaves in certain conditions (such
as on high or low rates). This is not necessarily to improve
your skills (
though it is never a bad idea!), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly finding that you've run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive. For example, if you're going to do
a loop, check your altitude, mind the wind direction
(anticipating rudder corrections that will be required to
maintain heading), remember to throttle back at the top and
make certain you are on the desired rates (high/low rates).
A flight plan greatly reduces the chances of crashing your
model just because of poor planning and impulsive moves.
Remember to think.
Have a ball! But always stay in control
and fly in a safe manner.
GOOD LUCK AND GREAT FLYING!

CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while flying, you notice any unusual sounds, such as a
low-pitched “buzz,” this may indicate control surface
flutter. Because flutter can quickly destroy components of
your airplane, any time you detect flutter you must
immediately cut the throttle and land the airplane! Check
all servo grommets for deterioration (this may indicate
which surface fluttered) and make sure all pushrod
linkages are secure and free of play. If the control surface
fluttered once, it probably will flutter again under similar
circumstances unless you can eliminate the free-play or
flexing in the linkages. Here are some things which can
cause flutter: Excessive hinge gap; Not mounting control
horns solidly; Poor fit of clevis pin in horn; Side-play of
pushrod in guide tube caused by tight bends; Poor fit of Z-
bend in servo arm; Insufficient glue used when gluing in
the elevator joiner wire; Excessive
play or backlash in
servo gears; and Insecure servo mounting.
