Note: Refer to the radio instructions for
specific information on transmitter setup.
Adjust both the Throttle and Steering trims to
the center position.
Turn on the transmitter, then connect the
battery to the ESC. It may be necessary
to adjust the throttle trim knob to stop the
propeller from turning while the throttle
trigger is in the neutral position.
Adjust the rudder trim knob so that the
rudder is centered prior to operation. You
may adjust this control to make the boat run
straight during operation.
Ensure the antenna is properly placed through
the antenna tube. It may be necessary to
slightly pull the antenna tube out to make
certain the radio range is sufficient.
