increasing speed and high gyro gain.
- Boost:
Boost is one of the iGyro's "expert functions", and its basic purpose is
to provide better stabilisation for models which are very unresponsive. In
extremely windy conditions this function may also provide a better
corrective effect. The fundamental effect of the iGyro's Boost function
is to produce a brief but very pronounced compensatory action right at
the onset of any external influence.
Boost can also be set differently for the various flight modes.
Caution:
- This function must be used with care, and the setting should only be
increased gradually, since too high a setting will immediately result in the
model oscillating violently.
- As a general rule we only recommend using this function if the "Normal"
and "Heading" modes do not provide the desired level of stabilisation; a
situation which may occur in models with slow control response and
small control surfaces.
5.7. Zero Gyro
You will find the ZERO GYRO function in the first line of the main menu.
This function has two purposes:
a) Calibrating the stick centre position
b) Resetting the control surface travel end-points
This function must be used if you subsequently alter the trims or the servo
travel.
Never select the ZERO GYRO function unless the transmitter sticks are at
centre, and the model is standing motionless, with the engine or motor
stopped.
After selecting the function, move all the sticks once to each end-point; this
action causes the iGyro to detect and save the end-points automatically
once more.
