Checking the Steering Operation
With your Motor Lifeboat and transmitter
on, move the steering stick to the right
to make the rudders move to the right to
incur a right turn. Conversely, when left
input is given, the rudders will move to
the left.
It may be necessary to adjust the
Steering Trim so the rudders are centered
prior to operation. You may also need to
fine-tune the steering trim to make sure
the boat runs straight during operation.
This can only be accomplished when
operating the boat in the water and is
detailed in a following section.
After you have completed checking your
radio system, turn the Motor Lifeboat
receiver off FIRST by sliding the switch to
the “OFF” position. After the model has
been turned off, turn off the transmitter.
Turning off the transmitter first may allow
the radio to accept stray signals and the
boat may run out of control.
If you find the steering or throttle
operates backwards as described,
you may need to actuate the servo
reversing switch.
Note: If you are transporting
your Motor Lifeboat, make sure
you disconnect the batteries from
the speed controller and then
turn your radio off until you are
ready to run the boat. Once ready,
simply plug the batteries into the
speed controller, turn the radio on
and make sure that the boat is in
neutral.
Range Testing
Collapse the transmitter antenna and
move the rudder controls. Walk away
from the boat and confirm that you have
control at least 20 yards away.
