d) Adjusting the rotor blade pitch using the control dials on the transmitter
The flight characteristics of the helicopter are greatly determined by the speed of the rotor head and the angle of attack
of the two rotor blades. The transmitter is equipped with two controls (ill. 1a, pos. 5, 6) to allow you to adjust the
helicopter to your own personal flying and control preferences.
Pitch limiter
If you push the control stick for the pitch function slowly
upwards (see ill. 1a, pos. 7), the swashplate will be slowly
lowered. This increases the angle of attack of the rotor
blades and increases the lift.
If you now leave the control stick in the top position, you
can use the pitch limiter (see ill. 1, pos. 5) to precisely
determine how far the swashplate should be lowered.
If you turn the limiter all the way anticlockwise, the
swashplate will not be lowered. If you turn it all the way
clockwise, the swashplate will be lowered to the maximum.
The pitch limit for the bottom position of the control stick is
set accordingly. If you push the control stick for the pitch
function slowly downwards (see ill. 1a, pos. 7), the
swashplate will be slowly raised. This decreases the ang-
le of attack of the rotor blades and increases the negative
lift.
If you now leave the control stick in the bottom position,
you can use the pitch limiter (see ill. 1, pos. 6) to precisely
determine how far the swashplate should be raised.
If you turn the limiter all the way anticlockwise, the
swashplate will not be raised. If you turn it all the way
clockwise, the swashplate will be raised to the maximum.
The two controls (ill. 1a, pos. 5, 6) will only be activated when the micro switch (ill. 1c, pos. 11) is in the
"ON" position. When the micro switch is in the lower position, the two controls (ill. 1a, pos. 5, 6) are
deactivated to prevent unintentional changes during operation.
