well together. If you prefer to use your own choice of equipment,
you do so at your own discretion, and you must accept the
responsibility for the results.
RR (Ready for Radio) = just the receiver remains to be installed.
Secure all loose cables using the cable ties supplied, and
ensure that they cannot foul or become tangled in the gearbox
or pushrods.
The model is designed for a 3S LiPo flight battery (11.1 V -
minimum current delivery capacity 35 A). We recommend that
you use the stated batteries. The price : performance ratio of
these packs is excellent, and they match the system perfectly.
However, if you wish to use a different battery, please note that
it is essential to check and observe the model's Centre of
Gravity.
Before every flight the airborne battery must be fully charged
using a suitable battery charger.
3. Checking the working systems, settings
As a minimum this model requires a simple four-channel radio
control system, without any mixers. Connect the system
components as described in the manufacturer's operating
instructions.
In the interests of safety you should remove the main
rotor blades before running up the motor for the first time,
and hold the model securely by the battery cradle. Ensure
that the motor cannot start running when you switch the
system on.
If you wish to check the function of the tail rotor with the
motor running but the main rotor removed, it is essential
to keep the system speed down to a very low level. Under
normal circumstances the main rotor acts as a brake on
the system. Without the main rotor fitted, the tail rotor
will quickly accelerate to speeds which are beyond its
safe capacity. At such high speeds the tail rotor will
probably fail, and could easily cause damage and injury.
When all the transmitter trims are at "neutral" (centre), all the
servo output arms should also be at the stated neutral
positions, and the swashplate should be exactly level. If this
is not the case, adjust the pushrod connectors.
When you apply a right "roll" (aileron) command, the swashplate
should tilt to the right (left command: left tilt).
When you apply a "forward cyclic" (down-elevator) command,
the swashplate should tilt forward (back cyclic: back tilt).
Mechanical adjustments:
The FunCopter is set up to suit the beginner perfectly. If you
prefer a more agile model, it is possible to re-connect the
pushrods to the outer holes in the servo output arms
(Caution: greater forces act upon the servos! If the rotor
should make ground contact, there is a much greater risk of
servo damage), and to re-connect the pre-formed rods (32)
further outboard at the rotor head.
If you apply a tail rotor (rudder) command - stick right - the tail
rotor pushrod should move towards the tail (left rudder: pushrod
moves forward).
Adjust the tail rotor linkage in such a way that it exploits the
full mechanical travel. If you have to limit servo throw, we advise
the use of the "Dual Rate" or "Travel Limit" function - assuming
that you have a computer transmitter. If your system does not
offer this facility, you may need to move the articulated barrel
on the servo output arm further inward (towards the centre).
The gyro used in this model is operated in heading lock mode
(for more information please read the instructions supplied with
the gyro).
When you apply full travel to one side and then release the
stick, in Standard mode the tail rotor servo would quickly return
to the neutral position when you let go of the stick.
In heading lock mode the tail rotor servo tends to "stay put"
at full travel. Don't be worried by this response: if you find that
the tail rotor "runs away" when the helicopter is stationary,
check the trim value of the tail rotor signal (for computer
systems: there must be no mixers acting upon the tail rotor
signal. Use a four-channel fixed-wing program for the
FunCopter).
If the helicopter is subjected to a major change in temperature,
we recommend that you leave the gyro and the receiver
switched on for about five minutes before flying. Switch the
system off after this period, then on again: the FunCopter is
now ready for the air.
The direction of gyro effect can be changed using the
REVERSE <- -> slide switch:
You can check the direction of effect of your gyro by abruptly
rotating the helicopter around its vertical axis. If the gyro
responds in the wrong direction, then the position of the
REVERSE <- -> switch is incorrect: it can be changed using
a tool such as a small screwdriver. The switch is located at
the right-hand end of the case.
Remember to switch the RC system off before changing the
switch position.
Note
More information regarding the gyro can be found in the
instructions included in the set.
4. Final checks
a. The tail rotor should be free-moving.
b. Install the main rotor blades again. The blades should move
freely up and down, without any tendency to bind, and engage
fully in the working position.
c. The swivel links should be tightened evenly and adequately,
in order to prevent them falling forward or back through gravity
alone.
d. All the electrical connections must make 100% contact:
the plugs should be pushed fully into their sockets, and all
loose cables should be secured using cable ties.
e. The cabin must snap fully into place.
f. Check the Centre of Gravity by lifting the helicopter by the
auxiliary rotor between two fingers: the machine should now
hang with the tail boom horizontal. Any corrections required
can generally be achieved by re-positioning the flight battery. If
not, add nose or tail ballast as required.
g. After every five to ten hours of flying check the washers 118,
and replace them if they show signs of wear.
5. Range-checking
Before you carry out a range-check it is essential to remove
the rotor blades from the blade holders; this minimises the
risk of injuring someone or damaging property if interference
occurs during the check, causing the motor to burst into life
unexpectedly. We recommend that you place the model on a
table for range-checking; leaving the model on the ground could
result in false readings.
