2. Now press the
CURSOR
will cause the plus or minus sign in front
of the large number to flash on and off.
You can set the direction of revolution
mixing on each side of the half-throttle
position by changing this flashing sign
with the (+) or (–)
Therefore, you'll either set plus or minus
for both sides of the throttle stick's motion
(indicated by the
R/U
the window).
Use the (+) or (–) key to match the mixing
direction to the rotor rotation: (–) gives
right rudder, (+) gives left rudder. Verify
that you get the proper motion of the
R-OF — Rudder Offset
The rudder offset function is used to change the neutral position (offset) of the rudder
when switch E is used to switch to idle-up. This function may be used to automatically change
the trim of a helicopter flying at high speed. A clockwise-rotation rotor helicopter tends to drift
to the right at high speed, so a rudder offset may be applied to yaw the helicopter to the left.
The necessary offset varies with model geometry, so it must be determined by noting
changes at high speed. The rudder offset is affected by both revolution mixing and trim.
Rudder offset is turned on at the same time as idle-up, switched by switch D.

cause the small percent sign in front of the
large number to flash on and off. At this
point you choose the percentage of revo
mixing for both sides of half throttle. You
may set a value of 0% to 100% for each
side by moving the throttle stick in both
directions, one at a time, and changing the
percentage number to suit. Now verify
that the rudder responds both the correct
direction and amount for travel on both
sides with the master control. If you wish
to return the mixing percentage to the
default 50% value, press both the (+) and
(–) keys simultaneously.
