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 aircraft 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 on using gyros with
airplanes for cleaner precision maneuvers, such as snaps and spins without over rotation, see p. 74.
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.

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.

• Assignment of the 2 switches (

• Caution: it is critical that you remember if you assigned switches to select the three additional snaps.

•Both of these may come as a great surprise and risk crashing if you are unprepared.
• 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
: activates 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 nulled 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.
