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 the ESC power
switch. The ESC will beep until you squeeze
the throttle trigger, indicating full throttle. 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.
The rudder control arm should move toward
the front of the boat when right input is
given. Conversely, when left input is given,
the control arm should move toward the back
of the boat.
The ESC will beep until you give full throttle
input. The auto sensing circuitry will
select full throttle position when you hold
full throttle during initial setup. Release
the throttle trigger. With the propeller
free from any objects, give some throttle
input to ensure that the motor is working.
If everything appears to be functioning
correctly, you are ready to run your boat.
Be sure to turn off the receiver switch, then
the transmitter to keep stray signals from
sending the boat out of control.
Note: The ESC has an over-rev limiter that
will not allow you to hold full throttle when
the propeller is not loaded (in the water). To
reset, return the throttle trigger to neutral.
The auto sensing voltage cutoff will also
cut off power to the motor when the ESC
senses that the batteries are nearing
full discharge.
Note: If you are transporting your boat,
make sure you disconnect the battery
from the speed controller and then turn
your radio off until you are ready to run
the boat. Once ready, simply turn the radio
on and plug the battery into the speed
controller, again making sure that the boat
is in neutral.
Ensure the antenna wire 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.
To range check your model, collapse the
transmitter antenna and walk 10 paces
away from the boat. Confirm that you have
control of the boat by actuating the rudder. If
range is acceptable, extend the antenna and
continue with the preparation of your model.
