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.

3.3.9 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;
others snap on elevator alone. Most models snap most precisely
with a combination of all 3 surfaces. Additionally, rate of speed and acceleration when using the snap switch
will affect how the model snaps. For information using gyros with airplanes for cleaner precision maneuvers,
such as snaps and spins without over rotation.
Adjustability:
• Travel: Adjust the amount of elevator, aileron and rudder travel automatically applied.
• Range: -120 to +120 on all 3 channels. Default is 100% of range of all 3 channels.
• Directions: Up to 4 separate snaps is fully adjustable regarding travels and direction on each of the 3
channels.
Note: for simplicity, the radio refers to snaps that use "UP" or positive elevator as "U" or "UP" snaps. This is
more commonly referred to as a positive or inside snap. "D" or "DOWN" snaps are more commonly referred to
as negative or outside snaps.
• R/U = Right positive R/D = Right negative L/U = Left positive L/D = Left negative snap roll.
• Assignment of the 2 switches (DIR-SW1/2) to change snap directions is fully adjustable and optional. If you
wish to have only one snap, leave the switches as NULL. (If assigned, SW1=up/down, SW2=left/right)
• Safety Switch (SAFE-MOD): a safety may be set up on your landing gear SWITCH, preventing accidental
