Powering On the Controller
This wiring - with the wire loop uncut - assumes hat the R/C radio will be powered by the
AX3500 controller. Other wiring options are described in “R/C Operation” on page 69 of
the User’s Manual.
Important Warning
Do not connect a battery to the radio when the wire loop is uncut. The RC battery
voltage will flow directly into the controller and cause permanent damage if its volt-
age is higher than 5.5V.
Powering On the Controller
Important reminder:
There is no On-Off switch on the controller. You must insert a switch
on the controller’s power tab as described in section“Connecting to the Batteries and
Motors” on page 13.
To power the controller, center the joystick and trims on the R/C transmitter. Then turn on
the switch that you have placed on the Battery Power wire or on the Power Control wire.
If the R/C transmitter and/or receiver is powered off, the display on the controller will alter-
nate the letters spelling “no ctrl” to indicate that it is On but is not receiving a control sig-
nal.
