Condition; Multirotor Functions - RadioLink AT9S PRO Manual

5.3.14 CONDITION

Revo., curves for idle-ups are often v-shaped to provide proper
rudder input with negative pitch and increased throttle during
inverted flight. (Rudder is needed to counter the reaction whenever
there is increased torque. In inverted flight, throttle stick below half
has increased throttle and negative pitch, therefore increasing
torque and rotating the helicopter unless the revo. mix is also
increasing appropriately.)
Additional flight conditions are available specifically for helicopters. These additional flight conditions contain
different throttle curves, collective pitch curves, revo. mixing, and trims (except IDLE-3) to make the
helicopter perform certain maneuvers more easily. Lastly, the gyro and dual rate functions may be set to
provide separate rates per condition selected, including one for each idle-up.
Additional idle-ups may be used to maximize the helicopter's flight characteristics in certain types of flight
(i.e. fast forward motion, backward) or maneuvers (loops, rolls, stall turns), or even the same maneuver but
changing from heading-hold/AVCS gyro mode to normal gyro mode. The AT9 provides 3 idle-ups to allow
the modeler 3 additional setups along with the normal flight condition. (Note that IDL3 does not include
governor settings.)
Adjustability:
• SWITCH G (AT9) or E (AT9) is programmed for normal (NORM), idle-up 1 (IDLE-UP1), and idle-up 2
(IDLE-UP2) curves, adjustable in CONDITION SELECT (IDLE-UP1/2, IDLE-UP3 items).
(IDLE-UP1/2 3-position type switch only, IDL3 2-position type switch only)
• Activated with the throttle curve for that condition in THR-CURVE.
• Curves are adjusted to maintain constant RPM even when the collective pitch is negative (inverted). Note
that REVO mixing has one curve for idle-ups 1 and 2 and a second curve just for idle-up3.
•Gyro settings may be set separately for each idle-up.
• Governor settings may be set up to follow Normal/Idle1/Idle2, but do not offer a setting to adjust for each of
the 5 conditions like gyro.
• Activating OFFSET makes the TRIM LEVERS adjust the trim separately in each of the idle-up conditions.
MULTIROTOR menu is the most differ between AT9S Pro and the other brand transmitter. The menu makes it
easier to fly multi-copters. The basic function menu is same like ACRO, GLID and HELI, please find the detail
in the former chapters.
Now let's start the basic setting, take a quad copter for example:

Part 6. MULTIROTOR FUNCTIONS
Steps
Install all servos switched, receivers, etc. per your model's instructions. Turn on
the transmitter then receiver; adjust all linkages so surfaces are nearly
centered. Mechanically adjust all linkages as close as possible to proper control
throws. Check servo direction. Make notes now of what you will need to change
during programming .
