Testing your Boat in the Water
1. Carefully place the boat in the water.
2. Operate the boat at slow speeds near the shoreline.
Avoid objects in the water at all times.
3. Once you are comfortable operating the boat at
slow speeds, it is safe to operate the boat farther
from the shore.
Tip:
If you are using too much steering trim on your
transmitter to make the boat drive straight, return
the trim to neutral and mechanically center the rudder.
To do this, carefully bend the linkage a small amount.
4. When the boat is moving forward, ensure water flows
out of the coolant outlet on the boat. If water does
not flow out of this outlet, remove any blockage from
the rear inlet and coolant system or the motor may
overheat.
5. Bring the boat back to shore when you notice
the boat starting to lose speed.
6. Power off the ESC and disconnect the battery pack.
7. Allow the motor, ESC and battery pack to cool before
charging the batteries or operating the boat again.
NOTICE:
Do not turn off the transmitter first
or the receiver may pick up stray signals and
run out of control.
Boating Tips
Avoid boating near other watercraft, stationary objects,
waves, wakes and other rapidly moving water, wildlife,
floating debris or overhanging trees. You should also be
careful to avoid boating in areas where there are many
people, such as swimming areas, park waterways or
fishing areas. Consult local laws and ordinances before
choosing a location to pilot your boat.
Maximum speeds are only achieved when the water
conditions are smooth and there is little wind. A sharp
turn, wind or waves can turn over a boat when it is
moving quickly. Always pilot your boat for the wind and
water conditions so that the boat does not turn over.
When running your boat for the first time, we
recommend calm wind and water conditions so that
you can learn how the boat responds to your control.
When making turns, decrease the throttle to reduce the
probability of flipping the boat over.
Never operate your boat in less than 3 inches (8 cm) of
water.
NOTICE:
When running at full speed in choppy
waters, the prop may exit and re-enter the water
repeatedly and very quickly, subjecting the propeller
to some stress. Frequent stress may damage
the propeller.
CAuTION:
Do not operate this product in vinyl-
covered or inflatable pools. Sharp components
may cause damage to these materials.
CAuTION:
Never retrieve your boat from
the water in extreme temperatures, turbulence
or without supervision.
Motor Care
Seat the motor brushes by driving smoothly on calm
waters during use of the first battery charge.
Avoid potential overheating conditions, such as blockage
in the cooling tubes, driving against heavy resistance or
debris in the drive system.
