Remote control
Balance the machine on the flybar, with the flybar at right
angles to the fuselage. Move the battery until the model
balances level when suspended by the flybar.
The canopy can now be mounted. For this, push the two
rubber grommets into the body molding if you have not
already done so.
Please make sure you wait until the canopy/cabin glue joints
are completely cured. Too much haste at this stage will make
mounting the body more difficult.
The main rotor blades are attached to the rotor head using 3x8
mm nylon bolts, washers and nuts.
See the exploded view for correct orientation and assembly of
these components.
The rotor blades should not be over-tightened. They need to
be tight enough to prevent them pivoting into the helicopter
when they are at rest.
They must be able to center under their own weight when the
head rotates. If they are too tight, the helicopter can shake and
vibrate. If they are too loose, the helicopter will be unstable as
the blades spin up.
Now turn on the transmitter.
WARNING: Only turn on the transmitter after you are sure that
the throttle stick is in the low stick or power off position and that
your transmitter throttle reversing switch (if present) is
correctly set.
SEVERE DAMAGE OR PERSONAL INJURY MAY
RESULT IF THE DRIVE BATTERY IS CONNECTED AT
HIGH THROTTLE SETTINGS.
KEEP FINGERS, LOOSE CLOTHING AND EYES WELL
CLEAR OF THE ROTATABLE PARTS WHENEVER YOU
CONNECT THE FLIGHT BATTERY TO THE
PICCOBOARD
Center all the trims. Move the throttle stick to the lowest
position. Plug the flight battery into the Piccoboard. Let the
machine sit for approximately 5-7 seconds until the LED
illuminates. Do not move the machine while the system is
calibrating.
When the Piccoboard LED glows red; the electronics are
active. Hold the throttle stick in the power off position and
check the operation of the cyclic controls. Move the elevator
stick back and forth and make sure the swashplate moves in
the right direction. Move the aileron stick from side to side and
confirm that it operates the swashplate correctly. Check the
integrity of all controls-right through to the correct operation of
the flybar paddles. Now, gently apply a tiny amount of throttle
ensuring that fingers, eyes and loose objects are well clear of
all rotating parts. The main rotor will begin to rotate first, then
the tail rotor. Throttle down again and unplug the flight battery.
Congratulations! You have finished construction. Your
FUN Piccolo is now in front of you, awaiting its maiden
flight. Before that, however, please charge your flight
batteries. Then turn to the chapter on flying.

Flying
Your FUN piccolo is completely assembled, the
battery charged and in place and the transmitter is
properly trimmed out.
A suitable flying site is required. Initially, a large
room or a small meeting hall without obstacles is ideal.
Make sure that the air in the room is still. Ensure that there are
no drafts from open doors or windows. We also recommend a
flat, smooth floor (such as tiles) so that the skids can slide.
Avoid carpet as it may catch the skids and cause a tip over.
If are a beginner; it is highly recommended that you seek
assistance from a professional R/C model helicopter pilot.
Please see the special notes for newcomers in the opening
section of this manual. Correct flight trimming is essential for
successfully learning to fly with the Piccolo.
N.B. The following flight notes are intended as a guide only
and are not intended to replace proper flight instruction
provided by a suitably qualified R/C model helicopter pilot.
WARNING: Before attempting to operate your Piccolo you
should be aware that the main rotor blades and tail rotor
blades can rotate at very high speeds and therefore can inflict
severe damage or injury to people or property.
In addition, the Piccolo is capable of flying at high speeds over
great distances and can cause considerable damage to
people or property if not controlled correctly.
Therefore, always take the utmost care with your preparation
to ensure that there is no possibility of damaging anything.
Especially, keep small children and animals well clear of
model helicopters at all times!
Place the helicopter in the middle of the floor. Before you turn
on the transmitter, make sure that the throttle stick is set to the
power off position and that the cyclic trims are centered. Make
sure that you have carried out a transmitter range check in line
with your R/C manufacturers recommendations.
Adjust the Piccoboard gyro gain and mixer potentiometers to
around 95% of full travel so that the slots in the gain and mixer
potentiometers are aligned vertically (both gyro gain and
mixer pots turned nearly fully clockwise)..
Plug the flight battery into the Piccoboard. After waiting for the
LED to activate, test that the servos are operating properly. If
everything is working correctly, position yourself (and any
others) at least 2 meters behind the helicopter and a little off to
one side. Be sure you can see the nose of the helicopter.
Watch the nose. Slowly apply enough throttle until your
Piccolo becomes light on its skids. If the Piccolo rolls to the left
whilst on the ground, apply some right roll trim to counteract,
and vice-versa.
Now apply a little more throttle slowly and see if the helicopter
shows any sudden movements. If it does not, that is good, but
stop! That does not mean that all is in order. It is possible that
the machine will tend to yaw it's nose to the left or right when a
small amount of power is applied , then straighten out with
more power, then yaw the other way with still more power.
This cannot be corrected with trim and indicates that the
Piccoboard tail rotor mixer is not properly adjusted. The mixer
controls the rotation speed of the tail rotor relative to the speed
of the main rotor in order to neutralize main rotor torque. If the
input from the main rotor to the tail rotor is too strong, turn the
mix adjustment pot on the Piccoboard to the left
(counterclockwise). This reduces the amount of main rotor-to-
tail rotor mixing. In the opposite situation, adjust the pot
clockwise. After this, you will probably need to readjust the
transmitter tail rotor trim. Please be patient with this phase as
the proper flight attitude of the helicopter depends on your
correctly performing all the steps in the instructions.
