The inverted cross position function sets the point at which low-side pitch is
crossed when switching between forward and inverted. It is commonly set to a value
of 30%.

Revolution mixing is used to mix pitch
→
rudder to suppress the torque reaction
generated by changes in the pitch and speed of the main rotor. The mixing ratio can
be set by a five-point curve.
Three are three kinds of revolution mixing: normal (NORM), idle-up 1 (IDL1),
and idle-up 2 (IDL2). Only basic NORM revolution mixing is displayed in the Basic
Menu, but all the revolution curves are visible in the Advance Menu. If you program
the normal curve in the Basic Menu, the same curve is automatically reflected in the
REVOLU NORM menu within the Advance Menu, and vice versa.
The REVOLU functions for the IDL1 and IDL2 curves will not operate until the
OFST-1 and OFST-2 functions are activated.
These two functions set the mixing rate so that the fuselage direction is straight
ahead during high-speed flight. You can set either a curve or offset position to
match the helicopter’s tendencies. You may also program in reverse rudder mixing
for 3D flight.
