Checking the Radio System
CAuTION: Always keep all body parts, hair
and dangling or loose items away from the propeller
and fin, as these could become entangled.
NOTICE: Always power on the transmitter before
powering on the ESC. Always power off the ESC
before powering off the transmitter. Never transport
the boat with the battery connected to the ESC.
1. Turn the transmitter throttle and steering trim knobs
to the 10 o’clock position.
2. Power on the transmitter.
3. Connect a fully charged battery to the ESC.
4. Power on the ESC and the boat will beep 5 times.
5. Ensure the rudder moves to the left when
the steering wheel is turned left.
6. Pull the throttle to full, then return the throttle to
neutral, ensuring the propeller turns counterclockwise.
Brushless boats have an over-rev limit that will not allow
you to hold full throttle when the propeller is not loaded
(out of the water).
If the over-rev limiter becomes engaged, rearm
the ESC by returning the throttle trigger to neutral.
The auto-sensing voltage cutoff will also engage when
the ESC detects low battery charge. If this occurs,
release the throttle and recharge the boat batteries.

failsafe
In the unlikely event that the radio link is lost during use,
the receiver will drive the servos to their preprogrammed
failsafe positions (normally no throttle and straight
steering). If the receiver is powered on before powering
on the transmitter, the receiver will enter failsafe mode,
driving the servos to their preset failsafe positions. When
the transmitter is powered on, normal control is resumed.
Failsafe servo positions are set during binding.
