27. Test-flying
Longitudinal dihedral = 0°; this is defined by the model itself.
Centre of Gravity:
Start by setting the CG within the stated range. Now to the
fine-tuning: fly straight and level at half-throttle, then roll
inverted. If you have to apply a lot of "down" to maintain
level flight, the model is nose-heavy, and you need to move
the CG back. If the machine tends to climb when inverted,
the CG is too far rearward. The CG is correct when you
need to apply just slight down-elevator for inverted level flight.
Correcting the tracking:
First the static balancing: hold the model by the spinner and
rudder; it should balance in the normal flight attitude. If one
wing is heavy (swings down), add ballast to the lighter tip.
During the next flight apply just enough throttle for the model
to remain airborne, and trim it for normal flight. Now fly the
model inverted and check its tracking. Add ballast if
necessary after the model has landed.
Sidethrust:
Place the model in straight and level flight, allow it to fly past
you at full-throttle, then pull up into a vertical climb. In a
vertical climb the model should show no tendency to fall
away to either side. If it veers to the left, add more right
sidethrust, and vice versa. However, please note that any
wind will also tend to push the aeroplane off course.
Downthrust:
Place the model in straight and level flight, and allow it to fly
past you at full-throttle, so that you view the model from the
side. Now pull up into a vertical climb. The model should
continue to climb vertically, with no tendency to tip forward
or over onto its back. If not, adjust the downthrust to correct
the fault.
After making these corrections you may find it necessary to
repeat the procedure for fine-tuning the model's Centre of
Gravity.

Aileron differential
Fly three of four rolls to the right at half-throttle; if the model
ends up veering off to the right, the differential needs to be
increased. If it veers to the left, the differential is already too
great, and needs to be reduced.
28. Gilding the lily - applying the decals
The kit is supplied with a multi-colour decal sheet. Cut out
the individual name placards and emblems and apply them
to the model in the positions shown in the kit box illustration,
or in an alternative arrangement which you find pleasing.
29. Safety
Safety is the First Commandment when flying any model
aircraft. Third party insurance should be considered a basic
essential. If you join a model club suitable cover will usually
be available through the organisation. It is your personal
responsibility to ensure that your insurance is adequate (i.e.
that its cover includes powered model aircraft).
Make it your job to keep your models and your radio control
system in perfect order at all times. Check the correct
charging procedure for the batteries you are using. Make
use of all sensible safety systems and precautions which
are advised for your system. An excellent source of practical
accessories is the MULTIPLEX main catalogue, as our
products are designed and manufactured exclusively by
practising modellers for other practising modellers.
Always fly with a responsible attitude. You may think that
flying low over other people's heads is proof of your piloting
skill; others know better: the real expert does not need to
prove himself in such childish ways. Let other pilots know
that this is what you think too. Always fly in such a way that
you do not endanger yourself or others. Bear in mind that
even the best RC system in the world is subject to outside
interference. No matter how many years of accident-free
flying you have under your belt, you have no idea what will
happen in the next minute.
All of us in the MULTIPLEX team hope you have many hours
of pleasure building and flying your new model.
