Troubleshooting Guide
Problem
Possible Cause
Solution
Boat will not respond
to throttle but responds
to other controls
Throttle channel is reversed
Reverse throttle channel on transmitter
Extra noise or extra
vibration
Damaged propeller, shaft or motor
Replace damaged parts
Propeller is out of balance
Balance or replace propeller
Reduced runtime or
boat underpowered
Boat battery charge is low
Completely recharge battery
Boat battery is damaged
Replace boat battery and follow battery instructions
Blocking or friction on shaft or propeller
Disassemble, lubricate and correctly align parts
Boat conditions may be too cold
Make sure the battery is warm (above 10º C [50º F])
before use
Battery capacity may be too low for
conditions
Replace battery or use a larger capacity battery
Drive dog is too near the stuffing tube
Loosen drive shaft side of the motor coupling and
move drive shaft small amount back
Too little lubrication on drive shaft
Fully lubricate drive shaft
Vegetation or other obstacles block
the rudder or propeller
Remove vegetation or obstacles from rudder or
propeller
Boat will not Bind
(during binding) to
transmitter
Transmitter is too near boat during
binding process
Move powered transmitter a few feet from boat,
disconnect and reconnect battery to boat
Boat or transmitter is too close to large
metal object, wireless source or another
transmitter
Move the boat and transmitter to another location
and attempt binding again
Another compatible transmitter is
powered on within range of the receiver
Power off all compatible transmitters
except the one you are trying to bind
Boat battery/Transmitter battery charge
is too low
Replace/recharge batteries
ESC switch is off
Power on ESC switch
Boat will not connect
(after binding) to
transmitter
Transmitter is too near boat during
connecting process
Move powered transmitter a few feet from boat,
disconnect and reconnect battery to boat
Boat or transmitter is too close to large
metal object, wireless source or
another transmitter
Move boat or transmitter to another location and
attempt to connect again
Boat battery/transmitter battery charge
is too low
Replace/recharge batteries
ESC switch is off

Boat tends to dive in the
water or takes on water
The boat hull is not completely closed
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
Trim tabs are angled incorrectly
Angle each trim tab up a small amount to lift the bow
or down a small amount to lower the bow
Boat tends to turn one
direction
Rudder or rudder trim is not centered
Repair rudder or adjust rudder and rudder trim for
straight running when control is at neutral
Vertical fins are angled incorrectly

when control is at neutral
Rudder does not move
Rudder, linkage or servo damage
Replace or repair damaged parts and adjust controls
Steering servo wire is damaged or
connections are loose
Do a check of steering servo wires and connections,
connect or replace as needed
Transmitter is not bound correctly
Re-bind
BEC (Battery Elimination Circuit) of the
ESC is damaged
Replace ESC
ESC switch is off
Power on ESC switch
Controls reversed
Transmitter settings are reversed
Do the Control Direction Test and adjust controls on
transmitter appropriately
Motor overheats
Blocked water cooler tubes
Clean or replace water tubes
Motor power pulses
then motor loses power
Weather conditions might be too cold
Postpone until weather is warmer
