water or takes on water
Boat tends to turn
one direction
Rudder does not move
Controls reversed
Motor overheats
Motor power pulses
then motor loses power
Boat blows over upon
acceleration
12
Possible Cause
Boat battery charge is low
Boat battery is damaged
Blocking or friction on shaft or propeller
Boat conditions may be too cold
Battery capacity may be too low for conditions
Drive dog is too near the stuffing tube
Too little lubrication on drive shaft
Vegetation or other obstacles block rudder or
propeller
Motor couplers are loose
Transmitter is too near boat during binding pro-
cess
Boat or transmitter is too close to large metal
object, wireless source or another transmitter
Another compatible transmitter is powered on
within range of the receiver
Boat battery/Transmitter battery charge too low
ESC switch is off
Transmitter is too near boat during connecting
process
Boat or transmitter is too close to large metal
object, wireless source or another transmitter
Boat battery/transmitter battery charge is too
low
ESC switch is off
The boat hull is not completely closed
Center of gravity is too far forward
Rudder or rudder trim is not centered
ESC may require full throttle range calibration
Rudder, linkage or servo damage
Steering servo wire is damaged or
connections are loose
Transmitter is not bound correctly
BEC (Battery Elimination Circuit) of the ESC is
damaged
ESC switch is off
Transmitter settings are reversed
Blocked water cooler tubes
ESC uses default soft Low Voltage Cutoff (LVC)
Weather conditions might be too cold
Battery is old, worn out or damaged
Batteries are too far back in the battery tray
Struts have too much positive angle, causing the
nose of the boat to lift and blow over
Water conditions are too choppy or windy
Solution
Completely recharge battery
Replace boat battery and follow battery instructions
Disassemble, lubricate and correctly align parts
Make sure the battery is warm (above 10º C [50º F])
before use
Replace battery or use a larger capacity battery
Loosen drive shaft side of the motor coupling and move
drive shaft small amount back
Fully lubricate drive shaft
Remove vegetation or obstacles from rudder or propeller
Tighten motor couplers and ensure the coupler is free of
lubrication
Move powered transmitter a few feet from boat,
disconnect and reconnect battery to boat
Move the boat and transmitter to another location and
attempt binding again
Power off all compatible transmitters except the one you
are trying to bind
Replace/recharge batteries
Power on ESC switch
Move powered transmitter a few feet from boat,
disconnect and reconnect battery to boat
Move boat or transmitter to another location and attempt
to connect again
Replace/recharge batteries
Power on ESC switch
Dry out the boat and ensure the hatch is fully closed on
the hull before returning the boat to the water
Move batteries back in the hull
Repair rudder or adjust rudder and rudder trim for
straight running when control is at neutral
Calibrate the ESC
Replace or repair damaged parts and adjust controls
Do a check of steering servo wires and connections,
connect or replace as needed
Re-bind
Replace ESC
Power on ESC switch
Do the Control Direction Test and adjust controls on
transmitter appropriately
Clean or replace water tubes
Recharge or replace boat battery
Postpone until weather is warmer
Replace battery
Move the batteries forward to adjust the boat's center
of gravity
Adjust a more neutral or negative strut angle
Adjust the struts downward to drive the bow of the boat
down or move the batteries further forward for better
weight distribution
