SAFE
Select Technology
When ying in SAFE Select mode the aircraft will return to level ight any time the
aileron and elevator controls are at neutral. Applying aileron or elevator control will
cause the airplane to bank, climb or dive, and the amount the stick is moved will
determine the attitude the airplane ies. Holding full control will push the aircraft to
the pre-determined pitch and roll limits, but it will not go past those angles.
When ying with SAFE Select it is normal to hold the control stick de ected with
moderate aileron input when ying through a turn. To y smoothly with SAFE Select
avoid making frequent control changes and don't attempt to correct for minor
Differences Between SAFE and AS3X Modes

Select Switch Designation
®
SAFE
Select technology can be assigned to any open switch (2 or 3 position)
controlling a channel (5–9) on your transmitter. Once assigned to a switch, SAFE
select ON gives you the exibility to choose SAFE technology or AS3X mode while
in ight. If the aircraft is bound with SAFE select OFF, the aircraft will be in AS3X
mode exclusively.
IMPORTANT: Before assigning your desired switch, ensure that the travel for that
channel is set at 100% in both directions and the aileron, elevator, rudder and
throttle are all on high rate with the travel at 100%.
CAUTION: Keep all body parts well clear of the rotor and keep the aircraft
securely restrained in case of accidental throttle activation.
TIP: SAFE Select is assignable on any unused channels 5–9. See your
transmitter manual for more information about assigning a switch to a channel.
TIP: Use your radio channel monitor to con rm that the four primary channels
are showing 100% travel while assigning the switch.
TIP: Use the channel monitor to make sure the switch you are assigning for SAFE
Select is active and driving a channel between 5-9 and that it is traveling 100% in
each direction.
TIP: Make sure your four primary channels are not reversed if you are having
trouble assigning a SAFE Select switch.

deviations. With SAFE Select, holding deliberate control inputs will command the
aircraft to y at a speci c angle and the model will make all corrections to maintain
that ight attitude.
Return the elevator and aileron controls to neutral before switching from SAFE
Select mode to AS3X mode. If you do not neutralize controls when switching into
AS3X mode, the control inputs used for SAFE Select mode will be excessive for
AS3X mode and the aircraft will react immediately.

Assigning a Switch
1. Bind the aircraft to choose SAFE Select ON. This will allow the system to be
assigned to a switch.
2. Hold both transmitter sticks to the inside bottom corners and toggle the
desired switch 5 times (1 toggle = full up and down) to assign that switch.
The control surfaces of the aircraft will move, indicating the switch has been
selected.
Repeat the process to assign a different switch or to deactivate the current switch
if desired.
