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
snap rolls while the landing gear is down. The safety switch is turned on and off with the landing gear
SWITCH.
• ON: the safety mechanism is activated when the landing gear SWITCH is in the same position as at the time
this feature is changed to ON. Snap rolls will not be commanded even if the snap roll SWITCH is turned on
with the gear SWITCH in this position. When the landing gear SWITCH is moved to the opposite position,
snap rolls may be commanded.
• OFF: Activate the safety mechanism in the opposite position from the ON function.
• FREE: The safety mechanism is completely turned off. Snaps can be commanded regardless of the gear
SWITCH POSITION.
Note: The location of the safety switch always follows channel 5. If channel 5 is reassigned to switch C,
for example, switch C is now the safety. If channel 5 is null or used as the second aileron servo, the safety
function will not be available.
• Trainer Safety: SNAP-ROLL is automatically disabled when the trainer function is activated.
Goals
Activate SNAP-ROLL. Adjust
elevator travel to 55%,
rudder travel to 120% in the
right/up snap. Activate
SAFE-MODE so snaps can
not be performed when gear
is down.
Adjust rudder travel in the
left/down snap to 105%.
(Note：using negative
percents can change any of
the 4snap directions. For
example. change snap 1to
'down' by changing the
elevator percent to -100%)
Steps
Open SNAP-ROLL.
Activate the function
Adjust the travel as needed.
(Ex: elevator to 55%，rudder
to 120%)
Optional: Activate
SAFE-MOD.(Ex: ON when
Sw E or Sw G is down,
meaning snap function is
deactivate when that switch
is in the down position)
