Controller Range Test
Before deploying the boat, test the controller
range by powering up, confirming operation,
and then walking away from the boat while an
observer at the boat confirms continuous
contact. Be sure to check onboard antenna
connections and to fully extend the handheld
controller antenna.
Other Tips
Before deploying in fast rivers or dangerous
situations, thoroughly familiarize yourself with
the way the boat responds to the controls.
When the boat is outbound, it will respond to
control signals much as expected. When
inbound (heading towards the handheld unit)
the same control signals create an opposite
response. During inbound transit, it will help to
leave the settings unchanged and to hold your
attention constantly on the boat.
Without sufficient practice, the usual first
response in an emergency inbound maneuver is
likely to be opposite the desired direction.
Make small changes with the throttle and
steering controls. They are sensitive and gentle
operation is all that’s needed to make the boat
respond.
To prolong the life of the motors and propulsion
system, accelerate slowly and gently. The
rudder servo consumes a lot of power;
minimizing rudder use will extend the power
endurance.
Power Up Process & Deployment
Caution:
Follow the correct power-up process
to avoid mishaps. Always activate the handheld
controller first. Activating the on-board power
switches with the handheld controller turned off
could instantly activate the rudders and props to
pre-set speeds. This is potentially dangerous.
Step 1.
Before powering the boat, confirm that
the handheld controller/wireless helm is turned
on, the props are clear, no one is standing near
the boat, and that the control sticks are in
neutral.
Step 2.
Turn on the on-board power switches.
Note the two switches on the lid of the
electronics box in Figure 2: Main Power and
Auxiliary Power switch (forward).
The main
power switch does not have to be on for the auxiliary
switch to provide power to the auxiliary port.
Step 3.
Before launching the boat, test forward
and reverse propeller operation to ensure
correct function. Move the rudder control (left
joystick) back and forth to make sure that the
rudder is working and that it doesn’t bind at
either lock. When ready to deploy, we
recommend backing the boat away from the
shore to minimize the potential for prop
damage.
Installing the ADCP
With the ADCP looking downward and sitting
on its cap, install the ¼-20 x 3”mounting studs:
insert the studs from above and install a lock
washer and standard nut on the bottom, leaving
no more thread than necessary protruding from
the bottom of the nut. (see Figure 4). Install a
hex nut from the top, using wrenches to snug
both nuts against the instrument flange. This
will leave about ¾” of thread protruding
upwards to pass through the instrument
mounting plate and receive the wing nuts and
lock washers.
Attach the mounting plate to the instrument,
and place instrument with mounting plate
attached into the well on the Q-Boat. Adjust for
height with standoffs if needed and secure the
mounting plate to the boat. Connect the
instrument cable to the ADCP and internally to
the modem.
