here you go

The axle is outfitted with the D-link, Axial lockouts/straight axles, Axial ud 43/13 gears and Highland Crawler no slop lockers.

[helhedded]

Here are a few pics of it all mocked up for link measurements. Shane did a hell of a job doing this by hand. With this configuration the front of the skid is at 2 7/8" and the rear of the skid is at 3.5" and the clearance at the links 3.75".












I still need some driveshafts, but this gives you the idea of how much more it will weigh in the end with everything on it. I can still lose weight in other places by running stock tranny gears or running a smaller motor, but I'll worry about that stuff later.

Looks good, put together!

Looks great, but mockup your rear driveshaft when you get it. Hope it's not too exposed.

[ROLANDROCKSHOP]

CLEAN!
nice,awesome job...you running a bec on that?

[jeepcj578]

Looks good

Very slick Ashton, the CF hand job is fantastic, Shane did a nice job. The belly clearance is in that sweet zone any more and you'll probably raise your COG without adding some low weight, it will still side hill really well. It looks like it's going to be very light rig, you can add low weight from here and still be light as a feather.

I should be a beast man.

Why have the front IC located out over the rear axle. Won't that make the truck floppy and torque twisty when using reverse?

What's IC ?

Thanks, Norm. I think it will end up right around 5lbs, but building a super light truck was not my goal. I just wanted to get weight out of the upper part of the truck. There are a few areas that I can and probably will tweak such as running a big bores upside down, all plastic tranny gears or even a smaller motor. The uppers will be TI and the lowers will be SS.

I'm not sure what you are talking about. I'm guessing that you might be referring to the upper link mounting points at the rear axle?

i dont wanna know

btw looks like PLENTY of room for a BTA setup so jump on that sir. who made that junk ass drag link on there anyways?

The short paragraph on wiki does a much better job than I can hope to.

Gotcha. No I am not worried about it at the moment, but I do have a few other 4-link options (that mount the links closer in line to where the lowers mount) if this one will cause any issues. In order to keep the pinion out of the rocks with the use of the current 4 link the axle as to be clocked that far.

Thanks for the link!

now here's one that I pulled up this afternoon

Got it....
Assuming this works for a front suspension logic as compared to a rear suspension logic.

The Instant Center and Center Of Gravity are related to each other. Where the IC is in relation to the COG effects squat/anti-squat. And caster would effect the location of IC.

So depending on where the COG for this rig is, will determine if the IC being out past the rear axle will help or hurt the suspension action/handling. And that hinges on what you want your squat/anti-squat setup to be on a crawler.

Plus, your only talking about reverse situations.

Helhedded will need to find COG first to see if your question is right/wrong.

Exactly, that's how my rig lost weight to I was mostly trying to lose high weight in those areas you mentioned. Made me smile when I read your response.

Five pounds is disgustingly light for a shafty, now you can add that nasty low cheating weight now.

Rootar your a dirty old man, but I see where my wording was pretty fawked up sorry Shane.

hahaha im not old! hell i dont even turn 23 for another month.

ashy, where are the BTA pics you should have that done by now!

bust my chops.

[helhedded]

While I'm waiting on parts I started messing with the electronics and their placement. I'll be using a de-cased Holmes Hobbies BRX-L ESC paired up with a Castle BEC.





This is the direction that I'm headed in.

[Duuuuuuuude]

You ought to polish those dull parts to match the blingy wheels.
