INSTRUCTION MANUAL

Locate the center horizontal fuse and both wing
panels. As you will notice both wings have different
sized domes where they connect to the fuse. Make
sure to match them to the appropriate sized dome
cut-out on the fuse.
Take your rear horizontal fuse and coat the area
where the wing will meet it with accelerator. This
will help to ensure a strong bond.
Locate all of your hinged surfaces. Place them in a
folded position with the seam facing the inside of the
fold and place weights on top of them for 30-60 min.
This will free up the hinge and allow the surface to
move freely.
Major components laid out flat on table

Once the slot is located ensure that you open up
the slot completely. There are still remnants of foam
keeping the wings together that will need to be cut
away in order to fit the wing spar. See below for the
open slot.
Place the front portion of the wing together with the
front portion of the horizontal fuse and allow to dry.
Now you have completed one side of the wing
attachment. Follow the
previous steps for the other
wing.
Locate your balsa wing spar, also locate the pre-cut slot
for the wing spar.

On the top side of the wing use medium CA to fill in
any void you may have missed when gluing on the
bottom.
Use thin CA to glue the spar into place on the
bottom of the airplane. You can also use
medium
CA for this but ensure you get glue on both sides of
the spar in the slot. Be careful not to glue your wing
to the table
Test fit the wood spar in the wing slot .Ensure that the spar fits completely down in the slot and
the wing stays flush with the table.

Add a bead of medium CA to the tail end of your horizontal fuse.Join the two together on a flat surface and allow a
straight and tight bond between the
two surfaces.
Take your accelerator and spray it on the horizontal stabilizer.Now locate the horizontal tail section. You will notice
like the wing it has a dome on one side that
corresponds with an indention on the horizontal fuse to
ensure proper alignment.

If needed afterward spray a small amount of accelerator on the CA.
Locate the bottom vertical fuse piece.
Once you have the servo arm centered you can power
down the servo and rotate the arm out of the way like
you see above. Then on a flat surface press the servo
into its slot. Use
medium CA to glue the servo into
place making sure it is flush to the table.
*Make sure the servo lead is coming out on this side
of the fuse as pictured above.
Next we will mount your Futaba PS-10 Servo for
elevator. Before we glue this in place please take the
longest single sided arm and power the servo up and
center the arm. This
will help the setup process.
Once located dry fit the fuse in the the horizontal fuse
check to make sure the nose mates with the
assembled portion of the fuse. Minor fitting may be
required.

On the bottom fuse piece spray accelerator so that
you can make a instant bond when gluing.
Now that your aileron servo is glued, grab your
bottom vertical fuse piece and lets prepare to
glue it in place.
Slide servo completely in slot and glue in with
medium CA. Make sure the servo lead is
routed back
towards the bottom of the plane which in the photo
above is the visible side.
*Take note of where the lead is when performing this
step.
Now find your aileron servo, and test fit in the correct slot,
as shown below
Skyleaf ST Manual

Now with your fuse weighed down to a table,
attach the stiffener and spray with accelerator.
Now the the bottom fuse is attached lets grab one of
our 45 stiffeners. You want to put CA on the 45 angled
part of this piece . This piece helps keep the fuse
straight.
Join the two pieces together ensuring the nose is
square.
Take your medium CA and liberally apply a bead all
the way down the horizontal fuse piece.
Next we will setup the ailerons. First we want to
locate the aileron differential arm along with he two
control horns.
Skyleaf ST Manual
Page 8 of 21

Use medium CA to glue the servo arm to the
differential arm. You can wrap this with sewing
string/alternatives to add extra strength or you can
also take a small servo screw and screw the aileron
horn and servo horn together to ensure the servo
arm is locked
straight.
Next up you will need to locate the two aileron
pushrods, heat shrink and the ball link ends for the
pushrods.
Press the horn into the slot and you can apply
accelerator. You will repeat this step on both ailerons.
Next apply medium CA to the horn.
Test fit the horns in their slots. If needed you can
trim the foam to open up the slots some.
In the package with your aileron servo locate the long
double sided arm. This is how you
will connect the
servo arm to the differential arm.
Skyleaf ST Manual

Now take one pushrod and press the ball link into
the control horn. The angle matches perfectly if you
insert the ball link from the outer wing tip towards
the fuse.
Next locate the micro ez link connectors. This will
consist of the metal base piece,
center screw, and black backing plate. This will
be mounted to the outer most hole of the
differential arm.
Next cut a small piece of heat shrink and slide it down
the pushrod and over the base of the ball link, shrink
this. This adds extra protection against the ball link
breaking free from
the pushrod.
The ball link ends have a small groove molded into them.
This is the side you will glue to the pushrod.
Using medium CA is easier on this step but thin
also works well.
*be sure to sand the rod ends so that there is a rough surface for
the CA to bond to.
Repeat the above steps for both pushrods until you have two complete sets.
Skyleaf ST Manual

Repeat the previous steps for both sides. You can
clip/cut any excess carbon left past the
micro ez link
connector.
*Make sure to be careful when cutting carbon rod as
fine particulate can become airborne Locate you PS-10 servo for rudder. Slide into the
rudder servo slot and make sure the
servo leads
come out on the same side as your other servos.
Using medium CA to glue the servo into place.
With the servo powered and the aileron flush with the
horizontal fuse tighten the screw on the micro ez link.
Once you have one pushrod connected to the control horn, power up your
aileron servo and center it. Then attach your servo arm and differential arm
to the servo.Ensure the the differential arm is angled forward towards the
nose of the aircraft.

Apply CA on the 45 pieces of this stiffener just like the first one.
Line up the top fuse and press it into place making
sure its perfectly square and flush with the nose.
Spray the fuse with accelerator so that upon making contact the bond is
quick and strong,
Put a bead of medium CA all the way down your top fuse as you begin
prepping it to join to the assembled fuse.
Once glued into place power up the servo and make
sure that it is centered and mount the
bigger single
side arm.
Locate the second 45 stiffener.

Locate your pushrod guides in the kit.
Next cut a small piece of heat shrink and slide it down
the pushrod and over the base of
the ball link, shrink
this. This adds extra protection against the ball link
breaking free from the pushrod.
Repeat the above steps for both pushrods until you
have a pushrod for rudder and
elevator.
Next up locate both your rudder and elevator
pushrod. (These are both the same length)along with
two ball link ends.
The ball link ends have a small groove molded into
them. This is the side you will glue to
the pushrod.
Using medium CA is easier on this step but thin can
also work. Be sure to sand the rod so that there is
good adhesion.
.
Attach a micro ez link connector to both rudder and elevator
servos
You will clip 12 of them off the small holder they are
connected to
