Micro Crawler

[VKTechnic]

I recently got myself 4 of these tires, so I figured that it was time to try my hand at a small rock crawler. I decided that it would be drive-by-wire (no battery on board) so that I could build to the scale of the tires.

Of course, there's no build without some failure, so here's the first prototype, which failed because of slipping steering pulleys.

This issue was fixed in the next prototype by removing the belt altogether, but it had another issue -- not enough front axle clearance. I also didn't particularly like the way the rear links were set up, nor did I like the way the L-Motor was sitting.

Third time's a charm, or so the saying goes. This time, I went to a lateral MOA (Motor On Axle) setup, and I moved the steering rack up 2 studs. This allowed me to still have a supported steering rack without it being too low to the ground.

Now the question I am here to ask of you all is...what should the body be for this crawler? (Or should I leave it as a bare chassis?)

A mini 'BOSS' of course! Neat job, it looks to have good articulation

I think the chassis is a little too long for a BOSS, but I might give it a shot!

Hmm...maybe interchangeable bodies is a good idea...

[Trawler Man]

Look good, man. I like the idea of a mini crawler!

If you can pull it off in terms of scale and available parts, i think a Generation 1 ('66-'77) or 2 ('78-'79) Ford Bronco would be awesome.

I see you put some "headlights" on your GT-R. Looks good.

Indeed I have. They block the steering though, so I had to make them removable. Will post details on the GT-R thread later today.

goood job ))

[Doc_Brown]

Sweet man! Yes you should make a mini boss!

[VKTechnic]

Honey I shrunk my BOSS! (and painted it yellow)

Is it only me that sees an empty little rectangle and no image? :/

Probably just you. Try this.

Great job Victor!

Thanks! Your little boss is really awesome!

Experimented with some photo editing, so here's another teaser.

im just a bit tired of seeing the Boss everywhere but it's cool anyway ^^

I'm going to make another body for it that can be swapped with the BOSS.

[Technyk32231]

Will there be instructions or more detailed photos, at least for the chassis?

Same here.

Would love to see something cool, in terms of body. 1969-1972 Chevy K5 Blazer, maybe?

[Junpei]

Yeah, well who isn't? I don't even want it anymore.. Sorry for the late comment, but that's a nice crawler. How about something model team style, maybe like this:

Is it too big?

[VKTechnic]

Finishing up the project. Got 3 bodies built (Yellow BOSS from before and two new ones...). Filmed the video already, now going through editing.

Body #2: Gray BOSS

Body #3: Bronco-inspired truck.

Love the second body, too much BOSS going around so you have extension cables going to a battery box?

If switches count as extension cables, then yes. My cables are all used up on my GT-R.

[Kronos]

Really like the red Bronco. Nice job.

[Trawler Man]

Great work, love the red Bronco.
