acoustic tones. At the same time, the timer in the
transmitter's display will start counting down and
every 5 seconds a two-frequency tone will sound.

This choice primarily infl uences the maximum
number of control channels which can be attached to
the DSC (direct servo control) socket, and thus also
available to a fl ight simulator or teacher/pupil system.
By selecting "PPM10" this will be control channels
1 … 5, for "PPM16" channels 1 … 8, for "PPM18"
channels 1 … 9 and for "PPM24" channels 1 … 12.

Autorotation
Autorotation is that state of descending fl ight in
which the pitch of main rotor blades are set such that
the rotor's speed matches the natural forces of air
fl owing through, like a windmill. This built-up energy
can be used for "recovery" lift to brake a descent by
appropriate blade pitch adjustment.
Autorotation is a means by which real and model
helicopters are able to land safely in emergency
situations, e.g. in the event of a motor failure. However,
the prerequisite for this is a well-trained pilot familiar
with the helicopter's characteristics. Quick reaction and
good perceptiveness are necessary because the rotor's
inertia can only be used once to generate recovery lift.

Range test
The built-in range test reduces transmission power
to an extent that a functional test can be carried out
even within a distance of less than 100 m.
Perform a range test on the Graupner HoTT system
according to the following instructions. If necessary,
have someone assist you in carrying out the range test.
