Build Thread Axial SCX24 - Project Doomsday

Sucks that so many issues have come up.

Sucks that so many issues have come up.

It's no biggie man. I am actually kinda happy to add some nicer stuff to it. I was gonna just toss a body and radio in it, but it's slowly turning into a pretty mean little kit. But even with all the bad parts, the axles, chassis, links, and driveshafts are almost worth the price of these chassis kits I think.

But yeah, it would probably be a lot better in the end to just build it from parts. The only thing is the links and driveshafts in decent quality might be hard to source. But those at least appear to be just fine on this, aside from, I believe, the rear-most driveshaft looks to be about 5mm shorter than it should be. But there is enough engagement on the spline I think.

Two steps forward and one step back. I'll get her done eventually

Grabbed a Super 8 front axle from LGRP. It will give it +16mm track width to better match the extended rear axles.

I still need to grab a new skid and rear upper link mounts, but I ran out of funds. All the sales just drained me this year.

I think I want to try these adjustable mounts from RampCrab because the mid and rear axles could actually stand to be rotated back a little to get the pinion angles correct.

And I'll be grabbing an Injora skid to mount the Treal transmission to.

Badass!

This is something different. Not seen anyone build a 6x6 mini crawler before. Looks awesome!

 

[Lucifur10]

I guess I should start working on mine now. Ps I have an extra one if anyone wants a deal!

 

[WickedFog]

Grabbed some goodies for this one. This should be nearly everything needed for this build except a few odds and ends. Still need to grab a couple sets of simulated lockout hubs because they just look cool.

Funds are depleted. Next up, two sets of these.

Before you say anything @Doom!, I'm not complaining. Just pointing things out so folks who are interested in buying this Gawdforsaken kit see the problems I'm facing. But the Doomsday curse has struck yet again on this build. It just never ends.

Anyway, the Treal crossmember arrived today. It was beautiful for a minute. True to form with this build, and as @Littlemotor said to me, it is just cursed with problems. The holes in the chassis didn't line up with the holes in the crossmember. So here we go again.

The locating pins on the crossmember didn't allow the upper link screws to go in. The holes in the chassis are off by about 1/2 of the hole. Hard to see, but here.

Now if you guys remember the MB24 build, the front axle servo mount is proprietary to Meus Racing. Only Meus servo mounts fit it. And since Meus is the only people I see making these 6x6 links and parts for sale individually, and their stuff looks exactly like this, I think this is a Meus kit. Remember the rear axle shock mount bolt on that build snapping? Yup. I think this is made by them.

Anyway, the quick fix was to file off the locating pins on my brand new, very pricey, very purdy Treal crossmember

But it worked, and you'll never see it from the Farmer City race track on a galloping mule, so I just don't give a rat's patootie anymore. It will look fine. Maybe some day I'll deanodize and polish everything. Doubtful

 

[WickedFog]

Oh, and the freaking wheels got backordered

And the tires I ordered are way too small in diameter to look right. But I kinda thought they might, and I may just use them on Mr. Crawly or Carnage. I just like the look of them

Reminds me of the ol’ full-size Buckshot Mudder! That’s awesome! Hopefully they’ll work on somethin’ else like ya said.. Shame about the curse that just keeps on cursin’..

Yeah, our Carnage build likes small diameter tires. These mud tires are actually 4mm bigger diameter, so I think they'll look good on it. I need to get longer front links to get the front axle out a little farther for them to clear the body.

How did I miss this? Whatcha got?

 

[Lucifur10]

I have an extra chassis. Ali sent two.

Oh yeah. Duh. Forgot about that. Well post it up. I'm sure somebody will buy it. It can't be as bad as this one

 

[Doom!]

Sucks that at every step you have had an issue.

I considered renaming it problem child. But I just can't do that. Not only because you gave it to me, but by the time he grows up he won't have any problems.

 

[WickedFog]

Pulled the rear axles to install the trusses that just arrived. The chassis got upset and tried to Imperial Walker it's butt out of here. I went to set it down and it did this on me

Now where did I put my snowspeeder? And where is Dak when I need him? Oh wait. He's dead.

I replaced all the bearing holder down screws with black oxide buttonheads. But I noticed after doing this the axles were a bit hard to rotate. Backed the screws off a half turn and bingo. Smooth as buttah.

 

[WickedFog]

My first Rampcrab parts, and they look great. Came with black oxide STEEL buttonheads too. Way to go Rampcrab

Axles were void of grease.

Fixed

Trusses installed. These have a narrower mount than the ones that came on it, which will give the upper links more triangulation, which should also help articulation.

 

[WickedFog]

Well, the Rampcrab trusses won't work with the upper slider on them. So back to the drawing board, or just use the lower portion with the single hole location. That's what I'm gonna do.

But doing that, the mid axle is not only rotated so the pinion is angled down, but the passenger side upper link hits the motor before the shock is fully compressed. So I am just going to 3d print some upper links to get the axle rotated properly and put a bend in them so they clear the motor. Then I will at least have a template if I decide to make my own metal links later on.

Another problem was one of the lower link mount holes on the middle axle wass stripped, so I had to source some longer screws and M1.4 nuts to attach the lower links. Problem solved.

Will get the links printed and post up some pics tomorrow.

 

[WickedFog]

Chassis rails have been reverse engineered. I should be starting on the body mounts sometime today after I create a few more simple parts (crossmembers) and create the assembly. Pain set in and I had to stop here. I can only get about 20 minutes on it before I have to take a break

 

[WickedFog]

Forgot to add this here. Chassy assy is done and I just got the chassis put back together. Although I didn't use the carbon plates between the rails. I used 3 of the aluminum standoffs instead. The battery will mount in front of the motor on the angle of the chassis rails after I design a plate to go there. The Rx will be mounted on some wings/nerf bars on the side of the chassis opposite the motor.

I ordered 8 Injora Mud Paw tires, which are a couple millimeter smaller diameter than the tires currently on this chassis. I really want some 60mm tires, which should leave a 4mm gap between the rears. But nothing in that size is what I want. Still looking. But these Mud Paw's will do for now.
