Default LC79 build

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 10x30 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

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

This is awesome.

There's so much cool here, from that super clean transfer case crossmember, to the unique build of the radius arms, and those custom front brackets attaching them to the housing. Keep up the great work. Thanks for sharing.

This reminds me of the golden days of RCC, when all the good stuff had to be made from scratch.

Thanks guys, much appreciated!



Replying to Meatmonkey, I started building as soon as I bought my first RC truck, out of necessity. "There's nothing like this on the market,I'll have to do it" . Or if it exists, I can't afford it



RC's are, to some extent, a reflexion of the owner so every RC of mine has to have something unique so building or modifying is just what makes me confortable. Yes, love to see other guys building stuff but now,the trend seems to be waves of projects as the brands release new models. Somehow, I think that's related to people moving from forums to Facebook/Instagram



Sorry about the rant




Back to the usual program:




Finished all the outer halves and painted them silver to look like factory steelies. Was challenged to do the valve stems as a joke but was something I didn't consider before and went for it. Nothing fancy, just M1 bolts with painted tips

Thanks. Means a lot. I think that a builder just needs motivation and patience. I don't consider myself particularly skilled






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)

I've been eyeing those tires, too; might need to grab some now.

Thanks! the tires are impressive for the price.




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

Thanks!




Thought in replacing the brushed motor for a 17.5t sensored brushless I've have 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 printed mount:











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

The offset rod-ends to finish the steering have arrived!!!!! I'll try to make the links tomorrow

In the meanwhile, saw real LCs with a different grille and copied them to 3D print in resin...Already printed the V1 and looks amazing. This photo is the V2 with cosmetic improvements

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....
