Offset; Delay - RadioLink AT9S PRO Manual

5.3.7 OFFSET

Optional separate trims in addition to those for the normal condition. This
function is used to automatically change the trim of a helicopter, for example,
when transitioned from hover to flying at high speed. A clockwise-rotation
rotor helicopter tends to drift to the right at high speed, so an aileron offset
may be applied to offset the helicopter to the left.
The necessary elevator offset varies with model geometry, so it must be
determined by noting collective pitch changes at high speed. The rudder
offset is affected by both revo. mixing and trim lever movement while in the
offset function.
Adjustability:
• Complete switch assign ability, plus a CONDITION option that creates/ switches between individual trims for
each of the idle-ups.
• When OFFSET is active (its switch is on), moving the TRIM LEVERS adjust the stored offset, not the trims in
the normal condition.
•When OFFSET is inactive (its switch is off), the OFFSET and any trim adjustments to it have no effect (model
obeys the trim settings of the currently-active flight condition.)
• When OFFSET is inhibited, trim adjustments made in any flight condition affect all flight conditions.
• Rapid jumps caused by large offsets can be slowed using the DELAY function.
• During OFFSET operation, the aileron, elevator, and rudder travels are displayed on each trim display in the
Startup screen.
Note: Remember, offsets and revo mixes are not recommended when using heading-hold/AVCS gyros
because they conflict with the automatic corrections to trim and torque that AVCS provides.
Goals
Set up separate
trims for each of
the three idle-up
conditions.
Adjust the idle-up
2 rudder trim to
correct for torque at
high speeds.

5.3.8 DELAY:

The Delay function provides a smooth transition between the trim positions whenever OFFSET, REVO,
MIXING, or THROTTLE HOLD functions are turned on and off.
Steps
Open the OFFSET function.
Activate the function.
Change switch setting to
Cond .
Select IDL2 .
Adjust trim settings as
needed. (Ex:rudder to +8% .)
Close menus and confirm
slowed transitions.
