Select Switch Designation

SAFE

Select technology can be easily assigned to any open switch

(two or three position) on the transmitter. With this new feature, you

now have the ﬂexibility to switch SAFE On and Off while in ﬂight.

IMPORTANT: Before assigning your desired switch, ensure that the

travel for that channel is set at 100% in both direction.

Assigning a switch

1. Bind the aircraft correctly to activate SAFE Select. 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 ﬁve times (one 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 if desired.
