1972 Sikorsky CH-53 GS - wip #2 - the work in palstic and wiring
First I opened the holes to get the external tank mountings fitted
First sight of the hull
Every possible lid will be opened
By thinning the plastics at the rear, I opened the compartment rooms
Then cutting throug the thin areas
Done
Building the "shelfs" of the electrical stuff rooms 😄
The hinges for the lids
The lid is mounted
Also the door is put in place
The steps and lids
Starting with the stingers (or how they are called) / frames of the sides
Fitting to the hull
On bulk for the lift side, one for the right sight. Each frame part is custom built because the hull wents smaller at the rear
The inner frames around the rear opening is not that good.
Sanding it down
Gluing small frames into the hull
Ecery frame is numbered for the correct location. So I'm still knowing, where to lay my hands on and where I have to put more details to.
The first frames are test fitting. Like it.
Building the tool box and a propper wall between the cockpit and cargo area
the horizontal beams / frames are in place
Whoho! A whale sceleton 😄. So far it is not glued in place because I'm not done yet. A lot of more details will be added.
The same procedure on the right side
First view from the cockpit into the cargo bay
Still not glued in place
So the frames on the sides are done. Now moving to the rear area.
Still numbered the frames
Nearly done with the big box above the upper flap
The upper flap mounted to test fitting the parts / frames / box
Looks good so far
Now it's time to do the upper frames and heating tubes
The whole frames in place for another test fitting
🙂
Yep. This is how I wanted it
The electrical compartments are done too.
Drilling the first holes for the lights of the cargo area. Starting with the easier part.
Another openings to prepare for the wiring and switches. For example the left fuel tank thing with main gear
Starting wiring
The first try with those wires were a failure. They were to thick and not that flexible.
Between the brain storming for the wiring I painted the interior in the proper color.
Put the painted parts in place.
This is my plan for the wiring. The thing is, that the hull is to pieces (like all aircraft model kits as far as I know) but the lamps have to work together. One switch e.g. has to light up the position lights left, right and in the rear (following light). So I had to think over switches and connectors to put the circuits together, which have to work together. The other thing was to keep in mind, that I want to use 9V power. So I need some resistances
Drawing the wires into the shell.
Then adding more colors for the details.
Another lines (fuel lines e.g.) of the helicopter installed
The electrical things of the cargo area in the bay underneath the cockpit.
First peek
First lights
The other led / smd led are in place.
Following light, loading light, cargo area lights
Searchlights, landing lights, cockpit lights - not finally installed. Just testing the circuits
Another look under the helicopter and it's lights
Using a mold to do a copy of the cockpit consoles of the Academy kit
With the over head console it is much better.
The wiring is almost done
The wiring to the rear includes the following light, this res stroboscpe light on the top and the loading l
The wiring for the position lights and a switch for different circuits
This thing will be able to give the power to the main rotor blades. The lamps are called "formation lights"
Now it's possible to rotate the main rotor head 360 degrees and more 😄 Three connections: two power lines one ground line
The rotate thing mounted in place and already wired
tiny holes for the cables to the main rotor blade tips.
This is the SMD LED for the main rotor blade tip
First curcuit is done (three SMD LED each circuit)
Mounting all main rotor blades. Another test.
The platina for the anti collision lights (this red stroboscope flashers)
Planning to lightening the dash board
Overlayed the photo etched part by Eduard.
Two SMD LED are in place. The connector is installed to. As a reflector I used BMF
I printed the decals onto transparent foil to get the instruments transparent
Building the third seat for the board mechanic guy
Put it on the seat frame
And it is able to swing it out 90 degrees.
The hydraulic cylinder for the cargo ramp
Reflectors for the landing ligts and searchlights
...in place
Another lightning test
😄 sweet
Building some benches
Benches installed
Opening the intake of the APP
Also opening the exhaust for the heating system
Drilling some handles onto the dog house
Adding another handles and little doors for the foot steps
One problem of the Revell kit is, that the landing gears are made in the position of flight - they are to high. So I shortened them
Drilling holes for a plastic / styrene axle to keep the nose gear stearable
done. The main gear
The main gear is shortened too. The left one how it is in the box, the right on in right hight when the CH-53 sits on the ground.
See the different?
Opening the exhaust vor the APP
Above in the picture how it was
Mounted in place
Opening other holes for "fresh air" to the cockpit (cold or to the heating)
And there was a bulb for the external fueling system. The German CH-53 doesn't have those system so I had to remove the bulb on the lower glass.

Inserting two grilles
The cockpit has it's consoles and seat belts (Eduard)
This step is also at the original helicopter for reaching the turbines. Why not using for the switches?
Drilling 112 holes
Drawing the lines, where rivets ave to be added
Some antennas were broken in the kit
Well. Make them both better 😉
Stupid as I am, I opened the cockpit windows after the hull was together and ready to paint.
The frames for the cockpit windows
Rebuilt the whiper arms and blades including a washing tube
At least I buolt some ground equipment for the base. One of it will include a 9V block battery to support the lights without any connection to high voltage.

Afterwards I'd like to upload the pictures of the wip. This part is everything up to the the preparation of the painting.
