j) Pitch/Tail Mixer „REVO MIX"
The larger the angle of attack of the rotor blades, the larger the counter-torque that acts on the fuselage. In practice,
this means that any change to the pitch control stick will cause a rotary movement of the fuselage around the vertical
axis (main rotor shaft).
For modern model helicopters such as the „HCP80", however, high-quality gyro systems that control this effect in-
dependently and thus render the pitch/tail mixer superfluous are installed. If the mixer is still activated, there may be
malfunctions. For this reason, check the mixer for whether all values are set to „0".
Proceed as follows to check the pitch/tail mixer:
• Call the function settings menu.
• Select the menu item „REVO MIX" with the buttons „UP" or
„DOWN".
• Activate the menu item with the button „SELECT".
The display shows the setting values for the flight conditions
„NOR" and „IDLE". All displayed setting values should be set
to „0".
• Push the button „SELECT" to call specific setting values
when required.
• Pushing the buttons „INC (+)" or „DEC (-)" permits changing
the mixing value or setting the value to „0" with the button
„CLEAR".
• The setting is saved automatically.
• Push the buttons „UP" and „DOWN" at the same time to re-
turn to the overview of the function setting menu.
