Snap Rolls (Acro) - RadioLink AT9S Pro Instruction Manual

surfaces.
• Elevators acting also as ailerons for extreme stunt flying or more realistic jet flying (optional).
• Redundancy, for example in case of a servo failure or mid-air collision.
Adjustability:
• CH2 and CH8 only. (With programmable mixing, could utilize CH5 as the 2nd elevator servo.
THROTTLE-NEEDLE uses CH8 and cannot be active simultaneously).
• Direction of each servo's travel may be reversed in REVERSE or the set percentages may be reversed here.
• Elevator travels independently adjustable (both directions and percent).
•Optional action as ailerons (defaults to 50% response). This response cannot be activated/ deactivated in
flight. Setting AIL1 and 2 to 0 disables this feature.
Note: if you want this, but on/off with a switch, set AIL1 and 2 to 0 here, and use 2 mixes. AIL-to-AUX2
(link/trim off, assign a switch), get aileron action from the elevator servos when the assigned switch is on.
The AILEVATOR mixing function uses one servo on each of the two elevators, and combines the elevator
function with the aileron function (unless aileron travel is set to 0). For aileron effect, the elevators are raised
and lowered opposite of one another in conjunction with the ailerons.'
Once AILEVATOR is activated, unless you zero out the aileron figures (see below), any time you move your
ailerons or any programming moves your ailerons (i.e. RUDDER-AILERON mixing), the radio automatically
commands both elevator servos to also operate as ailerons. To deactivate this action, simply set the 2 aileron
travel settings to 0 in the AILEVATOR function. This way the elevators will work only as elevators.
Goals
Activate twin
elevator servos.
Deactivate the

–as-ailerons
portion of this
function.
Note: depending
upon your model's
geometry, may
need to reverse
one servo or set a
negative
percentage here.

3.1.8 Snap Rolls (ACRO)

This function allows you to execute snap rolls by flipping a switch,
providing the same input every time. It also removes the need to
change dual rates on the 3 channels prior to performing a snap, as
SNAP-ROLL always takes the servos to the same position,
regardless of dual rates, inputs held during the snap, etc.
Note: Every MULTIROTOR snaps differently due to its C.G.,
control throws, moments, etc. Some models snap without aileron;
Steps
Open the AILEVATOR
Activate the function.
Optional: adjust up/down travel
when operating as ailerons. (Ex:0)
Optional: adjust total elevator travel
of each servo. (Ex: right servo
elevator travel to 98%,left to 96%)
