  Custom build 8x4 MAN TGX 26.540 support vehicle. Scale 1:14.

I need a support vehicle alongside the crane, and the Scania was not perfect for that job. As a result, the Scania was sold, which made an opening in the garage. The MAN was born!
As usual "standard" was not an option, so I went into custom construction-mode. An extra axle, extended length, custom rack with stuff behind the cab, complete rework of the sides and panels, and various small things here and there... the list is long!

Color: Deep blue metallic: Tamiya TS19. (My favorite!)    Light grey: RAL 7012

  My MAN was born like this. An everyday healthy, standard, 3 axle Tamiya MAN TGX Euro 5.

Take a good look. This will be the last "standard" you'll see for a while!
The Euro 5 version was impossible to get in Denmark, so I had to import it myself.

  First the original frame was used to copy the holes to a new set of frame rails, only 100mm longer.
This allowed me to add another steered axle. I wanted a four axle truck.

It was to be driven on two axles, and steered on the other two. A so-called 8x4.

  One thing went with the other, and soon after I had a finished chassis with custom rear end, servo mounts for the steering- and gear servo that go in the very front, and mounts for the second steering servo half way down. The fifth wheel will also be servo operated, and the servo will go right next to the second steering servo.

  The servo operated trailer coupling is mounted using an M6 nut, and bolted to the chassis via an aluminum bracket.

  The original side panels was cut, and split. Some go in front of the second axle, and the rest of the side panel goes behind the axle.
Here it serves as the door to a cabinet! (I'll get back to that..)
A similar construction can be found on the other side.

  The finished rear end. A lit license plate holder goes in the middle of the bumper.
The rear end is not quite there yet.. there is too many visible nuts and bolts.

I do want this truck to look more raw than the Scania, but this is too much..

  Problem solved!
And a couple of air connectors and 'electrical plugs' was added to the rear end plating.

  My trusted assistant!
Emily loves to play in my little workshop, and one day she got hold of some nuts and bolts.

  Note the helical brass gears! (Standard is regular gears made in nylon)

-and again I omitted the two springs in either end of the gear selector. I want my servo to control the position without anything interfering.

  The front axles were altered too. The area marked in red was filed down, so the axle could turn sharper.
It really does good for the turning radius!

  More and more components piled up as work went along, and I soon ran out of space.
It's amazing how much space these things take up, until they are put together...

  First, real big custom sup project: The rack with stuff behind the cab.

First: A strong frame in 3mm plastic..

  ... and then a tank in the bottom, as always.
The tank might look a little big, but it will hold the battery, so I could not do much about it..

  A shelf will sit over the tank, and I needed to figure out a few things and odd ends to go there.
I made four air tanks from 20mm diameter electrical tube to begin with..

  What is a heavy hauler without a cooler?
Screen door aluminum netting, a plastic structure, some foam within, and you're done!

  There is actually a fan inside the fan housing, completing the mock-up.

  A holder for the fire extinguisher, wheel stoppers, and air lines fixture in the middle.

  The upper center was used for a cabinet, here shown with the doors open.

  The bar across on top will hold orange rotary lights, work lights and two flashing warning lights.

  There is a space between the cab and the rack anyway, and I need somewhere to put some of the electronics.
This extra compartment will between the rack and the cab. It will be glued to the rack front side after painting.
Smokestacks will go on either side..

  The front can be removed, giving access to electronics within.

  Done!
Only details missing are the air hoses.. they will come asap.

Working lights: Rotary lights, two flashers, and two high-power flood lights.

  The cooler..

  The rear towards the cab.

  The utility enclosure open:
Right now only the wires for the lights are here.
The receiver and a few other components will go here later.

  Close-up for details.

  Note the small cabinet in the middle...

  It opens, of cause.
A few basic tools will go here later.

  Air tanks. The 'air lines' are actually electrical wire.

When you have a lot of "go", you need a lot of "wow!" Hence four large tanks.
In reality these are made from electrical tube, diameter 22mm.

  The huge fuel tank can hold my battery!
Easy access to the battery without having to turn the truck over.

My truck will share battery with other vehicles, so I bet this will come in handy!

  Instrument board, incl various modifications.
Note the little indicators right in front of the steering wheel and down to the right. It's small SMD LED's, and includes 2 x green for turn signals, 1 x blue for high beam, 2 x red and 1 x orange warning lights for 'Work light on', 'Rotary light on' and 'Flash on'. I also included a CB radio and a Cola.

The MAN dashboard came with a shelf for stuff, unlike the Scania where I had to built it all. Thumbs up, Tamiya!

  The seats got seatbelts.. it's the law here in Denmark..

  The finished chassis!

  Chassis painted, and ready for final assembly.

The grey is the same grey as I use for the crane: RAL 7012

  Making the push-pull that will go on the front, while waiting for the summer to arrive, so temp will be high enough to paint the cab.
The push-pull is made in 2mm brass, cut on a CNC, and silver soldered together.
The pin is actually an M4 screw, thread removed, and a handle soldered into the slot.

  The puch-pull is bolted to the aluminum bracket with the eight little M2 brass bolts.
The black sticker hides the holes etc.

  FINALLY warm enough for painting!

The colors I went with are:
Deep metallic blue: Tamiya TS19 on top of a light spray of light grey (Tamiya TS32)
The light grey on the chassis, equipment rack and stuff are RAL 7012, same as I used for the crane.

  Detailing with flat black around windows and such..

  Getting ready to fit the small top lights right above the sun visor.

The two horns are an add-on.

  Inside the roof.
Small warm white LED's shine into the top lights like shown.
Also in the picture: The fittings and wires for the rotary light bar.

  I bought the ready-to-use light assemblies from Veroma (item no. 191552) cause I didn't see any reason to fool around with individual LED's this time.
I can highly recommend these modules!  There's even a turning LED for the side fender...

Lights will be demonstrated later.

  Each side have four orange lights, spread out evenly.
Here are the two on either side of the cabinet... not on..

  As above, but turned on!

The black stuff is construction silicone from Bauhaus. It ensures a secure, but yet removable, fit... and also that no false light shine all over the place.

  I went with ready-to-use light modules for the rear as well. (Veroma, item no. 191550)

  Rear light fitted!
Normally I make my own rear light fixtures, but this time I went with the original. They look fine, and I have a crane waiting for me so time is limited.
The bumper, and the structure on the end of the chassis with the two air connectors, and the towing hook is all 100% custom.
The license plate holder has little white lights fitted.. of cause.
Lights will be demonstrated later.

  Now it's time to connect all the wires. Receiver, 2 x PS4a (4 channel on-off RC switch), twin-steer module, and the flash controller will go into the small cabinet between the cab and the equipment rack. Regulator (Servonaut M20+), sound module (Servonaut SMX) and speaker goes into the cab.

In this picture: The cab is only put in place for a short while, so I could get an idea of the space available for electronics.
The antenna on the side of the roof is an add-on.

  Speaker mounted inside the cab, all other electronics in also place, and all lights connected!

  My flash controller.

It has two channels, A and B. Each channel can drive up to four LED's, and it is possible to select if the channels should flash, or just show a steady, alternating light. I go with the flashing option, four flashes in channel A, then four flashes in channel B... and all over.

  Cover in place over the receiver, 2 x rc switch PS4a, twin steer controller, and the flash controller.

The Servonaut SMX sound module and the Servonaut M20+ regulator are both tied to the cab floor. A few pieces of hard foam ensures that no false light will escape the cab, AND gives the two expensive modules a shock-free home.

  Oh.. forgot a piece of deck plating at the rear end!

  Better make it as well.
A steel ruler and a sharp knife, and a few blocks of alu to bend and shape the deck plate over.

  A last moment idea: Side markings at the very rear.

The black stuff is silicone. I traps false light, and is soft enough that you can cut it out and replace the LED, if something happens.

  Done!!!!!!!!!!!!!!!!

The latest 8x4 custom vehicle leaves the garage after a six month build.
(One month wasted waiting for warmer weather..)

  It drives really, really well. The upgrade brass gears are more quiet than the standard nylon ones, and running is smooth thanks to the special motor (Truckpuller III, 12V.).

Other custom parts:
Extra front axle, side panels divided and reused as cabinets, and radio antenna.

  Custom parts:
Push-pull, flash under the wind shield, stuff inside the cab..

  Custom parts:
The entire rear end, equipment rack behind the cab, servo operated 5th wheel ("saddle") and rear tow hook.

  Close-up of the equipment rack.

  Yes, the license plate is not yet fittet. I need to drop by the motor vehicle office and get a set of plates...

  The hatch opens and reveals the servo for the rear tow hook.

  The hatch opens and reveals the 5th wheel ("saddle") servo, and the steering servo for the second front axle.

  The side opens, and reveals the on/off plus volume button.
(And a thermometer so I can monitor the ambient temperature.)

  The "fuel tank" opens, and reveals the 'fuel': The LiPO battery! (11,1 V, 5000mAh)

  The other side opens, and reveals a tool cabinet.. the very basic tools.

  Closeup for details.

The red bar is a tow bar, which fits both the front push-pull and the rear tow hook.

  Custom parts:
The sunroof are a real, clear plastic sheet with genuine sun filter on the lower side!

The cab is more alive when there's a little light within, also during the day.

  ALL tires are upgrade parts. Rear: Fulda Crossforce. Front: Fulda Ecocontrol.
Also note the custom hub caps on all rims.

Lead pellets are placed inside the four, inside rear tires for added traction.

  Custom parts:
The lower step board is stainless steel.

  All custom!
Note the little dots close to the middle of the red and white top: That is the rear facing flashers.
They, the rotaty lights and the work lights, work 100%.

  Note the deck plating between the rack and the cab. It's nice to have when accessing the engine area.

  Custom parts:
Dice, paper, iPhone, CB radio, Coca Cola.

The cab is lit, of cause (Not in this picture)

  Custom parts:
The push-pull!
The base plate is bolted to the frame, so it can be used without any problems. See how in the early stage of the build (above).
The pin is a M4 brass bolt with the thread removed, with a handle soldered into the screw driver grove.

  Overall view.

  Custom parts:
Twin air horn!

  Overall view.

  Closeup. I could have done more, and made more funny details, but I wanted to keep it faily simple and yet unique.

  The rotaty lights sits on two spacers, so the light bar is horizontal.
You often see these bolted directly on to the roof, which is not horizontal.

The black markings "robse.dk" are from www.rc3d.dk

  Light test!!!!!

First, there were nothing...

  ... then there was light!

Cab light, to be exact!   Four warm white LED's.

  Plus parking light..

  Plus low beam (same lights, but at higher intensity)..

  Plus high beam..

  Plus fog light..

The light modules also have turning light (not "curve light"), and I plan to come back to this later with a controller.

  Plus rotary light and flashers..

  Plus side markings.

-and I completely forgot about the turning signals! The MAN has one turning signal in each front head light, and one on each front fender, right in front of the front wheel.

  Same rutine from the rear:

  Parking light incl. license plate light..

  Plus low beam (same lights, but at higher intensity)..

  Plus turning signals (note the green light on the dashboard!)..

The dashboard:
There are two green ("turn signals"), one blue ("high beam"), two red ("work light" and "rotary light") and one orange ("flashers") SMD LED's, about the size of a "."  -all connected to the corresponding outside lights. They really adds life to the cab!

  Plus work lights and side markings..

  Plus brake- and reversing lights, rotary and flashers.

-and thats it! I'm done.. well don'ish.., some smaller details might pop up, they usually do..

  Details added: Air connectors to the (air) lines.

  Detail added: Now I can assist someone quickly, as this chain can go into the tow hook both back and front.

 

Detail added: License plates! Very realistic looking, crisp clear text, high quality, reflective background!

I got these from Fechtner-Modellbau.de item no 7129.
Note that he has license plates for many different countries!


  Details added: License plates added to both front and back.
NOW I can use the roads without upsetting the local PD :-)
