accelerating, gradually returning the elevator stick to neutral.
The tail will now rise; when the model reaches flying speed
apply gentle but deliberate up-elevator to lift off. Allow the
aeroplane to climb at a steady, fairly shallow angle, taking care
to keep the airspeed up!
From a closely mown grass strip a ground take-off works just
like on a hard strip, but the ground-roll will be longer. If you do
not have access to a take-off strip, a hand-launch works fine.
Caution: if your assistant is an experienced hand-launcher
then you can be confident of success; if not, watch out!
30. Hand-launching
Please don't try unpowered test-glides with this model - the
result is invariably a damaged airframe. The Mentor should
always be hand-launched with the motor running at full-throttle,
and always pointing directly into wind.
Ask an experienced modeller to hand-launch your aircraft for
you: he should run forward for two or three paces, then give the
machine a powerful straight launch, with the wings and
fuselage level. Use the controls to hold the model in a steady,
gentle climb - remember to keep the rate of ascent shallow
and the airspeed high!
Allow the aeroplane to climb to a safe height, then adjust the
trims on the transmitter until it flies in a perfectly straight line
"hands off".
While the model is still at a safe altitude, throttle back and try
out the controls on the glide. Carry out a "dry run" landing
approach at a safe height so that you are prepared for the real
landing when the battery runs flat.
Don't try any tight turns at first, and especially not on the landing
approach at low altitude. It is always better to land safely at
some distance from you, than to force the model back to your
feet and risk a heavy landing.

31. 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.
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 sen-
sible 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.
We - the MULTIPLEX team - hope you have many hours of
pleasure building and flying your new model.
