Congratulations!
You have just acquired the model submarine "Galathée", it is a crewed exploration submersible. We hope that this model will give ou as
much pleasure to build than to sail.
Design features:
Length: 540 mm
Width: 118 mm Height: 157 mm
Weight: 4 kg
Materials: PVC and PS
Autonom : Approximatel 2 hours
Operating mode of the Galathée submarine:
The Galathée submarine is a static diving model. To dive a gear pump fill a ballast tank inside the dr hull. The air in the ballast tank is
compressed b the water.
ools necessary:
Side Cutter
Mini Drill (Dremel or similar)
Set of files of various sections (round, punts and square)
Sanding paper grain 240, 400, 600
Soldering iron (min 25 watt)
Set of Screwdriver
Set of grips
Products necessary:
CA glue
Silicone sealant
Mastic pol ester
Paint ( ellow or other)
Recommendation concerning the radio order:
4 Channel R/C s stems
3 servos (standard size, ball bearings is preferable)
1 electronic speed controller 10 Amps (minimum)
his model is not appropriate to the children of less than 14 years!
Before beginning the assembl of our model, checks all parts, read the instruction carefull beforehand.
Remove each parts from the plastic sheets onl when ou use it for the assembl of the model (the best wa is to mark the corresponding part
number on it).
Caution: For reasons of safety the battery of the submarine need to be charged only when the dry hull is open.
Paint
You can choose the colour of the model.
The most important issue is to prepare the hull properl for painting (use mastic pol ester to mask the enclosures).
The surface of the hull must be sanded.

Use Scotch tape to fix the parts of the after h droplanes for the depth
control, C14 and C15
Locate the position of the after h droplanes.
Use a square to align C14 parts, glue it on the part A4 and on the shaft. Drill two holes diameter 6mm on the marks (stamps for linkages) of
the A4 part
Proceed in the same wa with the C16 parts After gluing ou can remove the scotch tape.

Glue the part C18 on C14.
Glue the part E6 (stick) in the housing of the diving planes C15. Put the shaft sealing (Simmering) in the boring of 11mm of D1. The
more flat face is inside the model hull. Do not glue the shaft sealing
ring.

Strongl insert the shaft sealing ring. Insert and glue the aluminium tube (water in/outlet tube) for the water
pump.
Cut the two discs E1 Together parts, quadrilobe rings, screw and E1 Disc
Check that borings are perfectl clean, insert the two quadrilobe rings.
(there is no direction for the quadrilobe rings)

Put threaded rods with the nuts and steel washer Tighten the nuts. Do not tighten nuts excessivel !
Check that all the parts are well in contact and that the unit is well of
square.
Glue (CA glue) b infiltration all the parts of the structure
Put the parts C9 and C10, do not glue it now! Insert the back of the hull on the frame, check and adjust all the parts.

Use CA glue on parts C2, D1, C1, C9 and C10 to tighten the whole. Solder the spark suppression filter on the speed 500 (suppressor
capacitors).
Mount the speed 500 with screws BTR M3 and steel washer, the gears
needs to works free.
Sand each parts of the ballast where ou put the glue.
Cut a piece of plastic strip (use the strip of 10x2mm on the kit) to the
dimension of the ballast, drill a hole with diameter 5mm.
Glue it in the low ballast. Attention! The low ballast have no border.

Insert the low ballast in the frame, check the height. Make a mark on the low ballast.
Mark the position for the water scoop tube (18mm from the edge, drill
a hole with the diameter 5.5mm. (low ballast)
Put the low ballast in the frame, attention with the orientation of the
hole (see picture). Glue the low ballast to the frame with CA glue.
Use silicone sealant to glue the water scoop tube (brass) in the ballast. Use silicone sealant inside and outside.

Cut a piece of silicone tubing for the water pickup tube.
Don’t forget to make a bias cut of the tube to permit a complete
draining of the ballast
Let dr the silicone sealant 24 hours before gluing the high part of the
ballast.
Put CA glue around the high ballast, including the small border. Insert rapidl the high part on the low part.
Set both servos for the rudder and diving plane . Drill a hole of 3mm on a servo arm.
10mm

Assembl of the roller for closing off water lines. Cut and sand the servo arm of the roller.
Set the BTR screw M5 with its spacer (brass tube F23), two steel
washers and its nut. Do not tighten the screw. Glue the two C11 parts
on the housing.
Install the silicone tube in the ballast outlet. Put a hose clip (see
picture).
Set the servo arm to the neutral position and tighten the screws. Drill four holes on the part C12 diameter 1.5mm. Use the holes of the
micro-switches

Fasten the two micro-switches with the screws 2.2x6.5 Fasten the micro-switch unit to the frame (holes are predrill) with two
screws 2.9x9.5
Bend the thin plate of the micro-switches slightl so that the electrical
contact is made when the servo arm moves on the right or on the left.
Adjust the spacer to the roller .Check the blocking valve b blowing
in the hose connection.
Fold with 90° the positive connector of the pump. Solder the spark suppression filter on the pump (suppressor
capacitors).

Put the spacer for the pump parts C13. Fasten the pump with two BTR M4, steel washer and nuts. Install the
hose connection from the ballast without forgetting the hose clip.
Install the hose connection to the water in/outlet tube.
Put the connector Cable to the pump (see electric diagram). For the connection of the micro-switches see the electric diagram.
Put the R/C receiver and the electronic speed controller on the

the side of the rod of 195mm, make the same on the rod of 175mm.
Glue the brass tubes ( ou can braze it).
Sand the ends of the brass tubes. You need to have onl 3 mm of
thickness for the quadrilobe ring.
Insert the two control rods on the quadrilobe bushing . Use the
195mm rod for the diving planes .
40 mm

Connect the servos to the linkages with the clevis. The rods must be
bent so that the linkages can move freel .
Use the rod for the alignment and mark the middle of the turbine.
Drill a hole of 2 mm in the alignment of its axis of rotation. Cut the mini ball link b leaving 5mm of length of threading.
Drill a hole of 2mm in the ball link socket . Place the mini ball link on the turbine. Fasten it with the nuts. Glue
the nuts with CA glue. Use clevis to connect the dive plane on the rod
(see picture).

You can now test your submarine for any leaks.
Start b connecting our radio after having checked that all the trims are with the neutral.
Check the direction of rotation of the propeller (Attention! not to destro the shaft sealing, limit to the minimum the starting of the engine when
the submarine is out of water)
Mount the tight tube, fasten the cap nuts after having inserted a steel washer, do not over tighten the nuts!
Now the submarine can be put into water for test.
Hollow the two holes of A1 so that there does not remain an more
matter at the interior.
Cut a piece of plastic strip (use the strip of 10x2mm on the kit) and
glue it with CA glue around the tube in the alignment of D3, proceed
in the same wa to the back of the tube.

Glue A1 on D3 (put the glue onl on the interior of A1 see picture). Cut in the lead sheet a strip of 90mm and 4 strips of 30mm.
Cut the lead strips in the middle. But don’t cut one strip of 30mm. B helping ou with the internal structure draw a line on each side of
the G1 tube (see picture).
Glue two pieces of plastic strip (use the strip of 10x2mm on the kit)
in the medium of the line b leaving spaces for evacuation of air,
proceed in the same wa on the other side.
Adjust and glue to 25mm of the two ends of the tube, two half lengths
of lead on each side. You need to curve the lead strip.
