water. Acetone or nail-polish remover can be used to
soften CA glue for removal from skin. Actually, CA glue
will come off of skin by itself with time due to the oils skin
produces. Excess dry CA can be rubbed off skin with a pumice
stone.
Excess dry CA can be rubbed off skin with a pumice stone.
CA glues can be hazardous to health when used incorrectly.
Because of the pungent odor, CA glues must only be used in
well-ventilated areas. CA glue has a limited shelf-life. Keep CA
glue in a cool, dry place with the cap firmly secured after
opening.
Use caution when tightening bolts or screws. Motor retaining
bolts, for example, only require minimum tightness.
Remember when tightening, for example, flybar paddle
screws, that they are threaded into plastic. It is easy to strip the
plastic if too much force is used. If any components' thread or
material is damaged by excessive tightening; it must be
replaced. Spare parts are obtainable from your dealer.

ENJOYMENT IN THE BUILDING AND FLYING

Glossary
For newcomers to model helicopter flying, we will explain
some of the special terms and a little theory.
MECHANICS:
The sum of all components in the helicopter chassis (including
the main rotor, drive gears, frame, shafts and rods).
SWASHPLATE:
This is the connection device for the cyclic control. It consists
of the outer ring, a bearing, and an inner plate. The outer ring is
connected to servos and does not revolve itself. Servo
movements are directed by means of the swashplate through
to the rotor head, or main rotor.
MAIN ROTOR:
This is responsible for steering the helicopter in flight. It
consists of rotor head, rotor blades, flybar and flybar paddles.
Cyclic control commands are sent via the swashplate through
to the rotor head.
ROTOR BLADES:
These are the rotating 'wings' of the aircraft. They generate lift
and allow the machine to fly.
FLYBAR PADDLES:
These serve a dual function; they both stabilize and steer the
main rotor blades. The paddles are operated by the
swashplate and associated linkages.
TAIL ROTOR:
This rotor generates the thrust required to counter the torque
generated by the main rotor. The tail rotor controls the
helicopter about the yaw axis.
SERVOS:
These are highly geared motor and electronic units that
control the swashplate.
SPEED CONTROLLER:
This is the electronic device that controls the power delivered
to the main electric drive motors.
RECEIVER:
Receives control commands from your transmitter and sends
appropriate signals to servos and speed controllers.
GYRO:
This is an electronic stabilization device. It senses motion. In
helicopters, it usually stabilizes the helicopter tail, dampening
unwanted yaw inputs, thus greatly simplifying flying.
MIXER:
This co-ordinates the speed of the main and tail rotors. It alters
tail rotor thrust so that increases or decreases in power do not
cause unwanted yawing. Receiver, mixers, piezo gyro and
speed controllers are all combined into the Piccoboard.
Basics
How does a Piccolo helicopter fly?
A helicopter generates its lift from rotating wings (the rotor
blades). As engine speed is increased, the main rotor revolves
faster and therefore generates more lift. Conversely, as motor
