Transmitter Setup (BNF Basic)

IMPORTANT: After you set up your model, always rebind the transmitter and
receiver to set the desired failsafe positions.
The GEAR Channel (CH 5) controls the retractable landing gear. If you are using a 6
channel transmitter, The FLAP Channel (CH 6) can be used to toggle SAFE Select.
With the values listed below it will turn SAFE on for half and full flap positions and
AS3X will be on for no flaps position.
To use the flap channel for the SAFE Select switch the values must be set to
+100 and -100 and the speed set to 0 temporarily to assign the safe switch in the
flap system menu. Then change the flap systems values back to the listing in the
TX setup. See the SAFE Select Switch Designation section of this manual to assign
the switch for SAFE Select.
Dual Rates
Attempt your first flights in low rate. For landings, use high rate elevator.
NOTICE: To ensure AS3X technology functions properly, do not lower rate values
below 50%. If less control deflection is desired, manually adjust the position of
the pushrods on the servo arm
NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting Guide
for more information.
Exponential
After first flights, you may adjust expo in your transmitter.
