J. Teaching the Cyclic pitch Geometry
CAUTIoN: Do not touch any stick on your transmitter when entering menu
point (J). This will cause unwanted flight behavior.
1. Move the rotor blades so that they are parallel to the tail boom.
2. Attach a pitch gauge to a rotor blade. The swashplate should be in the neutral
position and the blade should have 0° of pitch. If the swashplate is not
neutral with 0° of blade pitch, repeat menu point (G) before proceeding.
3. Move the aileron stick left or right until the pitch gauge has exactly 6° of
cyclic pitch.
ImpoRTANT: The Status LED should still be Blue at 6° of cyclic pitch. If the
Status LED is Red, Purple or Off, you must mechanically adjust the helicopter.
You can use:
A.) Shorter servo horns
B.) Shorter linkage balls on the inner swashplate ring or
C.) Longer blade grip linkage levers
4. If the pitch gauge has more than 6° of cyclic pitch, move the aileron stick in
the opposite direction until the pitch gauge is at 6°.
5. Release the aileron stick and press the setup button once.
K. Adjusting the Collective pitch Range
CAUTIoN: Do not use any pitch curves in your transmitter while adjusting
the Collective Pitch Range. Doing so will result in unwanted flight behavior.
1. Move the pitch stick all the way up (full positive pitch) and stay there.
2. Increase or decrease the maximum amount of positive pitch using the rudder
stick.
3. When you have achieved the desired maximum pitch angle, move the pitch
stick all the way down (full negative pitch).
4. Increase or decrease the maximum amount of negative pitch using the rudder
stick.
CAUTIoN: Make sure the blade pitch angle is moving in the correct
direction. Incorrect blade pitch angle can result in erratic flight behavior. If
the blade pitch is moving in the wrong direction, reverse the pitch channel in your
transmitter.
Push the setup button to save the selection and move to menu point (L).
