Too little lubrication on drive shaft
Vegetation or other obstacles block the rudder
or propeller
Transmitter is too near boat during binding
process
Boat or transmitter is too close to large metal
object, wireless source or another transmitter

Center of gravity is too far forward
Trim tabs are angled incorrectly
Rudder or rudder trim is not centered
Vertical fins are angled incorrectly
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

ESC uses default soft Low Voltage Cutoff
(LVC)
Weather conditions might be too cold
Battery is old, worn out or damaged
Solution
Reverse throttle channel on transmitter
Replace damaged parts
Balance or replace propeller
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
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
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

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
Angle each trim tab up a small amount to lift the
bow or down a small amount to lower the bow
Repair rudder or adjust rudder and rudder trim for straight
running when control is at neutral
Adjust the right or left fin angle for straight
running when control is at neutral
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
Perform the Control Direction Test and adjust controls on
