it diminishes when moved in the opposite direction.
This provides a fast and straightforward method of
adjusting gyro effect even in flight – e. g. to suit chang-
ing weather conditions – or to test-fly optimal settings.
Furthermore, the range of the gyro’s effect within trans-
mitter control travel in both directions can be restricted
by software.
In this context, be sure to comply with the
instructions accompanying the gyro,
otherwise there is a risk the helicopter will
be impossible to y.
On the
mc-16 HoTT transmitter the obvious choice
as transmitter control for the gyro is one of the two
sliders on the centre console, or alternatively to install
one of the optional INC/DEC buttons on the mc-16
HoTT transmitter, as fitted to the mc-20 HoTT trans-
mitter as standard. These buttons are virtually ideal for
this type of task, since – in contrast to a position-related
proportional control – their current position is automati-
cally stored, and is therefore reproducible at any time,
even after you change models:

Adjusting the gyro sensor
To achieve the maximum possible level of stabilization
for the helicopter with the gyro along the vertical axis,
observe the following:
• The controls should have as little friction and “play”
as possible.
• There should be no “spring” in the control linkage.
• Use a strong and – in particular – a fast servo.
When the gyro sensor detects a model rotation, the
faster its response – a corresponding corrective change
to tail rotor thrust – takes effect, the further the gyro
gain adjuster can be moved without causing the tail
of the model to start oscillating, and the better the
model’s stability about its vertical axis. If the response
is slower, there is a risk that the model’s tail will start to
oscillate even at low gyro gain settings. Here, further
reductions to gyro gain will need to be made – either by
using the default value under “Gyro” or the associated
transmitter control – to eliminate the oscillation.
If the model is flying forward at high speed or hovering
in a powerful headwind, the net result of the stabilizing
effect of the vertical fin combined with the gyro may
also lead to an overreaction that once again manifests
itself through tail oscillation. To achieve optimum gyro
stabilization under all conditions, make use of the op-
tion to adapt gyro effect with one of the transmitter’s
proportional controls.
