Construction manual
-
Place a pad on your workbench to protect the surface of your model
- Then you can start with the removal of the wings. In the example
shown here, KST – X10 are installed on the flaps and on the inner
ailerons. KST - HS08A are used on the outer ailerons. Prepare the servo
frames and grind them thoroughly at the bottom and on the side edges.
This is the only way to ensure a proper adhesive bond.
- Next, they glue a frame made of crepe tape around the servo shafts.
This is for protection and is needed to mark the exact positions of the
servo frames.
- The edges of the servo bay can be slightly reduced. Original have this
6mm width. If you shorten this to half, it makes it easier to install the
servo frames
- The recesses for the rudder horns are already prepared as standard.
These are used for orientation and the position of the servo frame is
marked. With the help of a geotriangle, a line (90 degrees to the hinge) is
drawn
In the outer ailerons, the rudder horns come to the bottom (classic
linkage) and there the position can be transmitted directly
-
-
On the flaps and the inner ailerons, the rudder horns come to the top
(crossover linkage) and there the position must first be transferred from
the top to the bottom.
To do this, as explained above, they draw a line at a 90-degree angle to
the hinge. Starting from the recess for the rowing horn.
- They draw this line to the end bar and then transfer the position to the
lower shell
From this point, in 90 degrees to the hinge, you can then draw the
required lines
- Next, roughen the surface in the servo shaft and then all adhesive
surfaces (servo bay and servo frame) are degreased
In the next step, the servo frames are prepared for gluing.
There are 2 possibilities: Either they wet the servos with release wax or
they wrap them in cling film. If this is not done carefully, you will not get
the servos removed later because they are firmly glued.
- Now all servos are screwed into their frames.
Important: With servo arm, fork head and a linkage (the length of the
linkage does not matter here)
The rear crossbar on the X10 can be omitted. The servo is fixed at 3
points (2 screws + the counter bearing) and this is sufficient
- Now the 6 servo frames can be glued in. For this they either use Uhu
Endfest or you mix a mumble of 24h resin with cotton flakes and some
thixotropic agent.
If your glue is ready, wet the places in the servo bay and the servo
frames with the glue with a brush. Place the servo frames in the desired
position and align it cleanly with the help of the previously drawn lines.
- After everything is in it, the position is checked again and the whole
thing is weighed down a little.
For this you can use small cups with 100g - 200g lead in each
- Once the whole thing has hardened, the ribs of the counter bearings
are glued to the lower shell.
For this again use an adhesive or mummy. It is important that this must
be touched very toughly, it must no longer flow. Pull the glue into a small
syringe. This makes it easy to bring the adhesive to the desired position.
- It is important here that no glue comes to the ball bearing
- When everything has hardened, the installation of the rowing horns
continues
Before the rudder horns can be positioned, the prefabricated cut-outs
must be reworked a little
- With the flaps and the inner ailerons, the opening is extended towards the
hinge so that you can continue with the rudder horn to get the pivot point
further towards the hinge
- If all cutouts are adjusted so far that the rudder horns can be glued in
then the rudder horns are ground and degreased. The cut-outs in the
oars should also be made dust-free and grease-free. This is the only way
to create a proper bonding.
- Start with the outer ailerons
Put some glue in the opening for you rowing horns and brush the rowing
horns a little with it.
After you have positioned the rudder horns, it is best to mount a pole.
You should prepare this beforehand. The exact length does not matter
because it only serves to align the rowing horn cleanly
- After the rudder horns are fixed to the outer ailerons (glue hardened),
the same procedure continues on the inner ailerons and the flaps
- With the flaps you should grind away a little bit of the plastic of the
frame because otherwise this is in the way of the linkage.
- As soon as the rudder horns are firm, they manufacture the appropriate
linkages for all linkages in the area, so that the desired deflections can be
achieved
- Next, the electrical connection between the hull and the surface is
created.
The whole thing is firmly installed on the fuselage and floats in the
surfaces.
wings - male MPX
fuselage - female MPX
Since 3 servos per area are to be connected and the connector has 6
poles, the conductors (red) are soldered together on 2 pins.
The location on the fuselage is marked and then transferred to the root
rib of the wings
- Then the whole thing is separated and adjusted with a file until the plug sits
sucking in the opening
- Before the plug is glued in, the exact position is transferred to the root
rib.
Apply some crepe tape to the root rib. At the position where later the
counterpart of the plug should sit
- Now draw the section with a pen
- Then they make a generous cut-out around the marked spot on the root rib.
The plug connection on the surface side will be floating, so the cut-out should
be made large enough.
- As a next step, the cables are prepared for the surfaces and cut to the
correct length
- If the cables are all prepared, the MPX connectors are soldered. If you
have the opportunity, you can then pour the whole thing cleanly.
To protect the cables, it makes sense to pour in a fabric hose
- That the cables will not rattle later in the surface, before pulling in the
cables, small foam pieces attached. These can be fixed to the cable with
a drop of second glue.
- For the connection between cable set and servo you can choose
between 2 variants. Solder directly or crimp connectors.
If you decide on a plug connection, it is important to secure it with a
good tape
- As a last step, the servo covers are now adjusted and attached
Now you can start the servo installation on the elevator. The intended
servo is a KST – X10 or X10 Mini. The whole thing is installed with a servo
frame without counter bearing. The procedure is the same as for
installation of the area servos.
- You have to create the cutout for the rowing horn yourself at the
elevator. When the cut-out is made and the rowing horn is prepared, it
can be glued in directly
- It is also important that the rudder horn is neatly glued between the
two bowls
- Now you can start installing the SR frame. This only needs to be
adjusted minimally and can then be glued in directly.
- Please sand the two GRP parts for fixing the rudder before gluing them
in. Check whether the steel provided for this purpose fits into the holes.
If necessary, they shall adjust them.
- The two cut-outs in the rudder pant, which are intended for the GRP
parts, are created somewhat undersized. Fit these as far as the GRP part
sit tightly in it.
Now the SR can sit and be aligned for the first time. Once you have done
this, carefully remove the rod that fixes the SR and remove the SR again.
Since the two GRP parts sit very tightly in the bridge, they remain in
place.Nun fixieren sie diese mit einem kleinen Tropfen Sekundenkleber.
Then the rudder is reassembled and checked whether everything really
still sits exactly as it should be. If this is confirmed, the rudder is
dismantled again and the parts are properly glued.
- Next, the electrical connection between the fuselage and the horizontal
stabilizer is established. In the example shown here, 4-pin connectors
from multiplex are used. Prepare the plugs and solder the required
cables.
Draw the desired location on the tail unit and create a cut-out for the
connector.
- Transfer the position of the connector to the tail carrier and create a
cut-out there as well. Before gluing the counterpart to the fuselage,
please check whether the position really fits and whether the function of
the plug is given.
- After that, they can continue at the rudder. This is followed by gluing in
the rudder horns. With the help of crepe tape, the position can be
marked.
- Now the opening for the ruderhorn can be made. Feel your way
forward bit by bit until the supplied rudder horn finds its place. Then it
can be glued in
- Now you can let the servo board try it out
Before you finally glue in the servo board, it is best to build the model
completely and place all components approximately in their position.
This is important to check how they will get there later with the focus.
- Prepare your fuselage board so that it fits your components to be
installed. In the Diana shown here, the fuselage board was painted black
for optical reasons.
- Once you have determined the exact position of the hull board, you can
finally glue it in. After this has hardened, you can attach the ropes of the
rudder linkage and lay all cables cleanly in the hull. The last works now
relate to the balancing of the center of gravity and the setting of the
settings.
