Keel and Rudder Tube
Assembly
1. Insert the Keel Tube from hull
top and reach the hull bottom then
epoxy the two End Caps in
place. There are three big end
caps and one small end cap.
The small one for the bottom hull.
Note: end caps are working as
waterproof and epoxy will help to
fill the gap between cap and
tube. Keel Tube might need to
trim the length , to keep it level
with the deck. However, do not
leave any excess epoxy on the
inside the tube as it will be difficult
to insert the keel shaft if there is
any hardened epoxy inside.
Note: You may need to sand
contact area A of the hull if tube
is higher than the deck.
2. Using the same way to install
Rudder Tube and the other
two end caps in place then allow
the epoxy to cure.

from the inside of the hull then
secure Winch Line Guide A and B
together on the deck. Do the
same procedure for the other winch
line guide assembly.
2. Trial fit the keel in place,trim the
contact area if necessary. Make
sure the keel fit into the hull
properly. Secure the keel shaft with
M4 Locknut by using the
furnished 4 way wrench. The keel
can make it inconvenient when
moving the hull around during
assembly.
3. Please use care when placing
the hull on stand as the stabilizer
will contact the Al. Stand B, it will
need slightly to rotate the hull and
let stabilizer go through the display
stand.
4. Install Rudder in place by
securing the Steering Arm and
Collar with 3x5mm Screw .
In this step you will need to connect
the Pushrod by threading the
Z-bend end to steering arm first
then thread the other end to the hull
so you can secure the arm with
collar inside to the rudder shaft as
illustration. Note: the pushrod and
rudder should perpendicular to the
steering arm.

1. Thread a Metal Clevis on the
pushrod. Attach the clevis to the
servo arm. Adjust the clevis so that
the servo arm and rudder steering
arm are at ninety-degree angle to
the pushrod when servo is in neutral
position. Attach the rudder cover
decal on the rudder cover
then drill (5/64”)2mm hole for
antenna to go through. Thread
antenna and attach the cover in
place.
2. Epoxy the Mast Mount in place.
Make sure there is no epoxy inside
the mast mount A as the Mast will
install in later. Epoxy the keel in
bottom slot and whole mast mount
is recommended if user would
enhance the performance, however,
the weakness is the keel can not be
removed.
3. Thread one end of the Jib Sail
Control String to the servo drum.
Make a Figure Eight knot in the
drum. Turn on the radio and make
sure the control stick is full down
then wind the string for two turns in
the drum then place the drum on the
winch servo.
4. Tie a Bowline knot to the Swivel
on the other end of the control
string. Keep the string about 1/8”
(3mm) out of the front winch line
guide. Note: The less turns of string
in the drum the less chance for
string to be out of the groove.
5. Do the same procedure on the
Main Sail Control String but keep
the string about 1-5/8”(40mm) out of
the rear winch line guide.
6. Do the sail adjustment in page
21, after you satisfied with the
adjustment then secure the drum
with the screw comes with the
servo. Next secure the Winch Servo
Cover with two Standoff and
3x25mm Wood Screw . You will
need to trim a notch for the string to
go.

Attaching the Rigging
Snaps
1. Attach the main mast assembly
to the main mast mount.
2. Snap on all the mast rigging
swivels to the chain plates as
shown.
3. Adjust the string adjusters so
main mast can stand up.
4. Attach jib boom swivel to the bow
chain plate. Adjust the jib sail
adjuster at the top so mast is
vertical.
5. Attach the main sail and jib sail
control lines to the main boom and
jib boom respectively.
6. Snap on the swivel of backstay
string to the stern chain plate.
Adjust the string adjuster. Do not
adjust the string too tight as head
crane might be too low to contact
the sail.
7. Trim the number decal then
refer to color box and apply on the
sheet.

Adjustment
1. Sail Adjustment
A. When the sail winch transmitter
control stick is in the full “down”
position, the sail winch servo drum
should rotate and the sail control
lines are tight. Jib sail and main sail
now are at about 0-degree. If not,
you may adjust the string length.
B. With winch drum is in the “full up”
position, open the main boom to a
deflection of about 80-degree.
C. It will be necessary to readjust
the “full down” setting again, as both
of these adjustments are effected by
one another. The goal is to reach the
best compromise possible.
D. Normally use the trim on transmit-
ter will help the adjustment. If use a
quality radio which has end position
adjustment function then it will be
much easier to adjust sail angle.
E. If user use other servo then the
control throw might vary. In this
situation, user will have to change
the position of the Chain Plate on
Main Boom and the Slider on Jib
Boom. Drill 1/16” holes at the
desired position then use furnished
2x8mm wood screw to secure the
slider and the chain plate.
2.Rudder Adjustment:
Make sure that the rudder deflects
30-degree in each direction. If it
does not, move the clevis closer to
the center of the servo arm.

Before sailing your ETNZ for the
first time, take note of the
following:
A. Using clear tape, seal the radio
hatch cover after turning on
your radio to prevent water from
entering the hatch.
B. Make sure that your transmitter
antenna is extended completely.
Make sure that the receiver
antenna is completely uncoiled
(either inside or outside the hull).
C. Always turn the transmitter on
before the receiver, likewise,
turn the receiver off before the
transmitter.
D. Check that each sail, line, snap,
and fitting is properly installed
and adjusted.
CAUTION:
Periodically check all knots if loose
and the inside of the hull to make
sure that there is no excessive
accumulation of water.

Suggest to test the boat in light
wind. ETNZ has scale sail which is
much bigger than the normal 1M
racing yacht, stronger wind will
bend the boat very much, properly
control the angle of main sail and
operate the yacht in light wind
is recommended.

1. If your boat carries weather helm,
incline the mast a bit forward.
2. If your boat carries lee helm, incline
the master a bit backward.
• Refer to the explanation of weather
helm and lee helm below
Tuning Your ETNZ for Proper Operation
Straighten any left or
right leaning of master
Straighten any forward or
backward inclination of master

Maintaining an optimum sail profile is
important for both speed and control.
You may need to make some finer
adjustments to your tuning to obtain the
sail profile you want. The sail profiles

Weather Helm and Lee Helm
With the Rudder in line with the Keel, if the boat tends
to turn windward, it is said that the boat carries
weather helm. If it tends to turn leeward, it is said that
it carries lee helm. The situation in which the boat
shows neither tendency is called balanced helm. In
general, a boat carrying a slight weather helm is better
in performance than one carrying lee helm or having
balanced helm. Therefore, after adjusting the boat to
balanced helm re-adjust it so that it carries slight
weather helm.
Starboard Tack and Port Tack
The right side of the boat is called starboard and the left
side of boat s called port. When the yacht sails with the
wind cross the starboard and the mainsail is on the port
side, it is said that the boat is on a starboard tack. When
it sails with the wind cross the port and with the mainsail
on the starboard, it is said that boat is on a port tack.
You can sail on a starboard or port tack when sailing
close-hauled (i.e. windward), wind abeam (i.e. leeward).

* Sail your ETNZ only in still bodies of water. Never
sail your boat in running water such as streams or
rivers, as it is easy to lose control of your boat.
* Do not sail ETNZ in very heavy winds.
* If you will be operating your ETNZ in the same area
as other R/C craft, be sure that you are all on different
frequencies to help avoid any mishaps.
