It's a printed taillight with a real piece of stoplight inside


And this:

You guys don't imagine for how long I've waited for that extra bit of patience to fit the weatherstripping in the windows and then, the wipers



first 3 are done

The henglong gearboxes are not up to the task.I'm already on the second set.

Working on new system using these gearboxes:



Ordered a 30:1 to test

Thought of machining the structure but 3d printing could do the job



First of all, I'll not say that this was my original creation

There's a german shop( https://www.modellspiegel.com/) who created and sells these gearboxes for 1/16 tanks:



I had several ideas for the new drivetrain and the chosen was heavily influenced by this layout above

But I the time, I'm not in condition of forking out all that money and also like to do things myself as much as possible


To the build,this is where it sits now:





Need to do a test trial to see if the ratio it's good or not, and then order the other gearbox

First trial of the setup on 3s. It's so good when things work at first try. Unfortunately, the gearbox it's too fast(33:1,actually), I've already ordered a slower one. The only bad thing was that the bores on the gears are a bit off center, that's why it sounds that way

Now with slower gearboxes(56:1),everything assembled, even correcting the pinion bores that were off-center(the reason of the noise in the last video)

there it is,assembled and working. Just need a cover to reduce some noise and prevent that some LED wires don't get caught on the gears. The electronics are not in place because I'm about to take everything out to paint the hull





There's some video.Sorry about the background but I can't go to the woods right now

My goal of closing off the drivetrain it's closer to finish.Needed something on top to keep away dirt and sand




And a small rubber lip on the cover to keep sand and dirt away




First idea was a standard cover but started to mess with the 3d printer and decided to do a more elaborate clear cover to see the gears working(might sound like a joke but many non-rc people who see this truck don't understand how this truck moves or why it needs 2 motors...)

Now a small detail that it's almost invisible but wanted to do it anyway

Each road wheel arm has a piece atached to the hull where the axle pivots


So printed 8 of these:





OD paint to cover it all



These were meant to be bolted on but will try with glue only, for now

The M548 often came with the winch to load cargo,mainly ammo




I thought mine would look more complete with it so...3D printed the I-beam and the winch:




It's held in place with small zip-ties:







It has a chain, only needs a hook or a D-ring

Dollhouse stuff:

Thought that the operator needed some goggles for his helmet. The first idea was to scratchbuild everything but my Dremel broke so I've copied the goggles' frame from a real army model and 3d printed it.The lens are from a bit of clear package plastic and the strap is a strip of bicycle inner tube













And a set of binoculars to spot other fellow truckers














The binoculars are printed, the strap is a strip of rubber and for the lenses, I put a drop of green threadlock in place(designed those parts like small cups)

Final details:


One is a set of tags and labels, like this one:



Through social media,came to know a soldier who works on the base where all our M548s are. He gladly helped by taking photos of their tags and labels that I've remake in vector to allow proper resizing. Then they were professionally printed and all the text is clear!







The other one came to mind a couple days ago. The seat cushions I've had were fine. Cloth with foam inside, just don't look very scale

So, took some modelling clay, did a mold to have a uniform thickness , the texture was made pressing cloth to the clay and the stitching was with a spatula. Roughed them up a bit and the next day, applied Tamiya XF-62

Life's full of sacrifices like take a new truck to a beach to see how it handles:

Took the chance of letting the M548 out and visit the beach
