Corse dei CoMandi
1. Accendere trasmettitore e ricevitore del modello. Controllare i movimenti del timone agendo sul trasmettitore.
Quando lo stick va a destra, anche il timone deve andare a destra. Se questo non avvenisse bisogna invertire il verso
del servo dal trasmettitore.
2. Con il radiocomando verificare il movimento dello stabilizzatore. Portendo lo stick dell’elevatore verso il basso, il
suo bordo di uscita si dovrebbe muovere verso l’alto.
3. Usare una riga per regolare la corsa di elevatore, timone e spoiler. Misurare la corsa del timone nella sua parte
inferiore, l’elevatore sul bordo di uscita e gli spoiler dal loro bordo di uscita verso l’ala.
elevatore
su: 23mm
giù: 20mm
timone
destra: 50mm
sinistra: 50mm
spoiler*
Piena corsa: : 7/8 inch (22mm)
* Quando si aprono gli spoiler, viene ridotta la portanza prodotta dall’ala e quindi aumenta il rateo di discesa del
modello. In questo caso è necessario controllare l’assetto del modello con l’elevatore.
Queste misure sono indicazioni generali misurate nelle nostre prove in volo. Si possono variare leggermente per
adattarle al proprio stile di volo.
La regolazione delle corse e dei sub-trim non sono menzionati perché ognuno se li regola in base alle proprie
preferenze. Montare sempre le squadrette a 90° rispetto alla linea centrale del servo. I sub-trim si usano per
centrare i servi ma soltanto come ultima risorsa.
Si raccomanda vivamente di rifare il “binding” del radiocomando dopo che si sono fatte tutte le regolazioni. Questo
evita che i servi si possano muovere a fine corsa prima che trasmettitore e ricevitore siano connessi.

Preflight Trimming
We strongly recommend that before you fly your new
model, you first perform a test glide. Pick a flat spot that
has soft, tall grass and is free from obstructions. You
should always check out the performance of the aircraft,
as well as your performance as a pilot. The test glide will
allow you to make corrections to any building or control
defects that may have been overlooked. The test glide
should be done with an assistant on a calm day.
Tip : A good time for a test glide is either very early
in the morning or at dusk when the wind is calm. It is
important to concentrate on what the model is doing
while still having time to think about what you’re doing.
We will assume you have an assistant during the
following steps:
1. Range check your radio system and check the control
throws. Make sure the control surfaces move in the
proper direction.
2. Have the assistant hold the model under the wing
near the CG and run forward until they can sense the
wing developing lift. Don’t release the glider yet. See if
the model wants to lift. If not, add a bit of up elevator
trim and try again.
3. Have the assistant run forward again, this time a bit
faster with the wings level and the nose of the plane
pointed at the horizon. Once the assistant feels enough
lift being generated, have him/her thrust the model
forward in a straight line toward the horizon and release
the aircraft.
4. When the assistant releases the model, watch it
carefully. A properly trimmed aircraft will fly straight,
gliding to a smooth landing about 50 feet away. If the
model pitches nose down, the CG is too far forward and
you have a nose heavy condition. Remove some weight
from the nose, shift the battery aft or add weight to the
tail. If the model pitches nose up sharply and stalls, you
have a tail-heavy condition (the CG is too far aft), and you
need to remove weight from the tail, move the battery
and receiver further forward, or add nose weight.
5. Turns to the left or right after launch can be adjusted
through the use of right or left rudder trim.
Important : Make any trim adjustments in small
increments. Large changes can result in abrupt turns,
causing tip stalls and loss of control.
6. If you have to make large trim adjustments on your
transmitter, you may have other problems, such as
warps. Check the wings, elevator and rudder to make
sure there are no warps in the airframe. Make sure the
wings are aligned and mounted properly on the fuselage.
When you have the model trimmed and the CG adjusted
so it glides properly in a “hands off” manner, return your
transmitter trim switches to their neutral position. Make
the appropriate mechanical linkage corrections to return
the control surfaces to their test glide positions.
7. After you have made the necessary corrections,
test glide the model again to make sure it is trimmed
properly with the transmitter trims in neutral.

what are thermals
The first step to thermal flying is to have a basic
understanding of what thermals are and how they work.
If you have some concept of how a thermal works, it will
help you know where to search for them. A thermal is
basically rising air. The temperature of the ground is not
consistent. Different textures, colors and even weather
condition can cause uneven ground temperature.
Warmer ground temperatures heat up and form
warm air bubbles. The bubble will hug the ground until
something causes it to break from the surface tension
and release into the air, much like a soap bubble breaking
away from the water’s surface. Once released, perhaps
by a tree line, shed, building, etc., the thermal bubble
rises up and continues to gain energy until it is fully
developed many thousands of feet above.
Thermals are typically stronger later in the day, since
after a day of sitting in the sun, the ground has more
time to generate heat. There are still thermals in
the morning and evening; however, and they behave
differently. Morning thermals are very narrow, meaning
they have a small diameter and do not typically go very
high; perhaps 20–400’. However, there are many small
thermals in the morning, making it an excellent time of
day for learning how to fly sailplanes. Morning thermals
are very defined and are more safe, as they typically
don’t go too high and not as violent as fully-developed
thermals. Also, there are many smaller thermals close
together in the morning, and this will allow you to hop
from one thermal to another with ease.
