Heli-Specific Basic Menu Functions - RadioLink AT9S PRO Manual

Set up throttle curve for
normal. (Usually changes will
not need to be made prior to
first flight.）
Set up collective pitch curve
for normal as base of -4,
center of +5,end of +8 to +10
degrees of blade pitch for
aerobatics.2 (If just learning
to fly, ask your instructor.)
Set up REVO. Mixing for
normal. (For heading-hold
gyros, inhibit REVO.)
Confirm gyro direction.

Learn how to operate
HOVERING PITCH and
HOVERING THROTTLE
Be sure to follow your model's instructions for preflight checks, blade tracking, ect. Never assume a set of
blades are properly balanced and will track without checking.
Check receiver battery voltage! Always check voltage with a voltmeter prior to each and every engine
start.(Never assume being plugged in all night means your radio gear is ready to fly).Insufficient charge,
binding servo linkages ,and other problems can result in a dangerous crash with the possibility of injury to
yourself, others and property.
Confirm the swashplate is level at 0 travel. Adjust arms if needed.
Apply full collective and check that the swashplate remained level and there is no binding. Repeat for full
cyclic pitch and roll. If not, adjust as needed to correct in END POINT :
Important note: prior to setting up throttle hold, idle-ups, offsets, etc, be sure to get your normal
condition operating properly.
Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and
having completed all range checks, etc, gradually apply throttle until the helicopter becomes "light on the
skids." Adjust trims as needed to correct for any roll, pitch, or yaw tendencies. If the tail "wags," the gyro
gain is too high. Decrease gyro gain.
1. Periodically move the throttle stick to full and back down to ensure proper servo settings.
2. It is critical that dials A and C be centered when the pitch and throttle curves are setup.

5.2 HELI-SPECIFIC BASIC MENU FUNCTIONS

MODEL TYPE: This function of the PARAMETER submenu is used to select the type of model programming
Open the THR-CURV/NOR
function. Adjust if needed.
Close the function.
Open the PIT-CURV/NOR
function.
Adjust each point to desired
Curve.（Ex: first Point:8%）
Close the function.
Open the REVO./NOR
function.
Adjust to your desired
starting point.
(Ex: 10%.)
With radio on, move helicopter's tail to the right by hand.
Close the function.
The gyro should give right rudder input (leading edge of the tail rotor
blades move left).
If the gyro gives the opposite input, reverse direction on the gyro unit
itself.
Steps
Notice at half throttle,
the VR(B) dial adjusts
the throttle separately
from the pitch. VR(A)
adjusts the pitch
separately from the
throttle.
