J Teaching the cyclic pitch geometry
At this setup point J, you have to tell the MICROBEAST the available cyclic pitch range.
First don‘t touch any stick on your transmitter when entering setup menu point J. Orientate one of
the rotor blades so that it is parallel to the tail boom (Fig. 28). Then attach a pitch gauge to this rotor
blade. The swashplate should be in the neutral position and the blades should have 0 degrees of pitch,
otherwise repeat the swashplate servo centering at setup menu point G.
Now move the aileron stick until the rotor blade has an exact 6 degrees of cyclic pitch and then release
the stick ( Fig. 29). If you moved the swashplate too far you can steer the stick to the opposite direction
and reduce the pitch. Also by moving the tail stick to one direction you can delete the adjustment and
reset the swashplate back to 0 degrees.
The direction you choose is not important, what is important is that you keep the position steady on 6°
when you save and leave this menu step. It is not enough to go to 6° and then move back before saving
and leaving.
When reaching 6 degrees, the Status-LED should light blue. This indicates that your helicopter‘s
rotor head geometry is perfect for the use with a ybarless system. Otherwise, if the Status-LED‘s color
is red or purple or even if the Status-LED is o, this indicates that your helicopter‘s geometry is not
optimal for ybarless usage. Correct this by using shorter servo horns, shorter linkage balls on the inner
swashplatering or longer blade grip link levers.
Push the button to save the conguration and to proceed to setup menu point K.
Note: This menu item will not be left automatically after 4 minutes, so you have plenty of time to adjust
the mechanical setup.
Always set the cyclic pitch to 6 degrees! This setup does not aect the maximum rotation
rate of the helicopter but is only there to show the MICROBEAST the actual mechanical cyclic
geometry. A wrong adjustment at this step may be extremely detrimental to the performance of
the MICROBEAST. The blue color of the Status-LED is secondary and just for information.
