LC79 build

[Member ScaleAddict Scale Off Road Pro★★★★★★]

Hi!

Some time ago, my buddy TheGamer sent me a nice Killerbody LC70 loaded with extras. Not related to this particular event but shout-out to him, one of the few people I can call friend :).

Was happy to get a LC70 but I had nothing in mind for it,besides knowing that wouldn’t be “hardcore”

Risked on these Austar 1.55s and were a pleasant surprise. A 90x24mm tire,super affordable, sidewalls with many details and a soft compound? to top it off, they don’t seem knockoff of a know brand tire(correct me if I’m wrong)

Next, ordered Yota II axles and did a set of narrow 1.55s to allow the wheels being tucked inside the body. Stuck on the idea of rear leafs

Start tinkering with frame rail design and laser cutted these .

more to share soon

Thought a lot on how the front suspension will be and because of the gearbox chosen, the best option was to copy the 1:1 and do radius arms!

The 3D printer was useful to mock up the mounts and even the arms and had those laser cut afterwards. The mounts are 2 pieces of 10×30 steel tubing that shaped to look more like mounts. The bushings are servo rubber bushings. Every modeller has some laying around

Unpainted, they stand out too much, maybe a bit of black would help. The extra “fin” on one of them is to shape for the panhard mount

And because I want a bit of performance on this truck, did this panhard mount out of brass 😛

The gearbox will be the gearbox from the KingKong CA10. Is an affordable gearbox with scale looks and nice features: 18.2:1 ratio, wide steel gears,aluminium motor plate and full bearings. The only bad thing about it is that it’s shape with motor is not builder friendly. Needs a bit of tinkering to make it work on a chassis. It’s the third chassis I put this on

The servo is also in place and the it’s mount doubles as front body mount

All this flex!

This is what I’m aiming for:

Chassis is on hold right. I’m waiting for offset rods to make the steering links

But in the meanwhile, I can make from metal the wheels I’ve 3d printed to mock up the truck:

They were machined on a lathe, drilled on a drill press. There’s a thin hex hub behind and M2.5 scale bolts holding everything. The “hub” is an eBay special that I’ve ordered a set for the Unimog but stands out too much. I think it sits well here

I’m aiming for the stock Toyota steelie, that’s why they will be painted silver

Thanks!

 

Major disappointment

Built the wheels around these hubs although they were 6 holes. Today, while mounting a wheel, the nut went through .Upon closer inspection, hubs are bad designed as the nut tightens against a section that’s only 0.4mm thick and have nothing behind.

Quality hubs wouldn’t have that problem..live and learn, I suppose.

Why didn’t I’ve made my own 5 hole hubs? machining the 12mm hex hole is the most challenging part to do

Change of plan: Design my own hub but for pin. I will machine them out of brass if I have the chance. Did the printed prototypes and lost 6mm on wheel to wheel width!

(By the way, the M3 threads come out pretty good, considering the size..used a tap to clean them though)

Did the hubs in brass. A bit rushed but they seem to work. Still waiting for the set of M3 scale bolts

Thought in replacing the brushed motor for a 17.5t sensored brushless I’ve got laying around. It’s a LRP so it should be good. Tried a 2s and seems that low RPMs are nice and there’s no cogging . The problem was that the motor was so close of the servo that the sensor plug wouldn’t fit…So I’ve returned to the old idea of having the servo next to the motor and did this new mount:

Holds the servo, will hold the front of the body and is also the spacer for the gearbox. I think it looks cleaner

An idea came to mind today and did these bolts between jobs…

 

Video!

These leaf shackles came with 4mm holes in one end(3mm on the other) and no matching hardware. And like the leaf holes are 4mm, thought on these “cheater” bolts that allow some rotation to help when flexing. Don’t know if was made before…

 

Having the rod-ends allowed me to do the steering link. Did this one like some trucks have,altough different to the real LC79s. It should have been BTA with a drag link on the front but lack of space didn’t let me do that. Next is a definitive servo link and move on to how to hold the battery and body

This is the V1 grille my buddy TheGamer printed. The V2 has improvements, I’ll show it when I get it. We live far apart….

How it’s sitting, right now. I’ve improvised a battery mount and already tested it indoors with one of those new ISDT esc70 ESCs…. really excited in how it handles.

 

I’m also working on the 3D printed parts to hold the body at the rear. Speaking of that area, I’ve removed all the fragile hooks and hinges from the rear section, added my own metal ones, covered the holes I’ll not use. Got also rid of the frames for the taillights. I’ll do tailgates on the bumper more on the style we have here in this country

So I’ve made a scaled down version, with an upper section bolting to the stock bed holes and 4 lower parts. There’s M2.5 bolts threaded on the upper section that go through holes on the other parts and then hold with nuts

 

The battery seems to found the definitive place, with this tray that sits on the rails. On the cab, is right under the seats. Planning to print with another filament because this one sucks…

I’m making a cover to mimic the rear sheetmetal of the cab so the battery will be well hidden

This week worked on rock sliders. I don’t want to hit the doors on the rocks. The body came with a set but they’re a bit bland.

First, welded 4mm collars on the rails:

And the rock sliders:

5mm main tube, 4mm outer tube and mounts. The mesh came from a pen holder

Done. You can even clean your boots before stepping in!

Finally could paint the resin grille TheGamer printed for me. Came out great off the printer!

All black and the logo was done with a silver Sharpie…

 

 

 

Tinkering with the mud flaps in TPU to replace the bland stock ones…

[Member ScaleAddict Scale Off Road Pro★★★★★★]

This TPU is the best I’ve had until so when I’ve saw this empty space at the rear window…

…I’ve had to design it’s rubber:

While we are it, also did for the side windows:
