Clanker's Hulksta

[Postclanker]

So as I mentioned, got my gears and axles straight this morning. Conveniently forgot how these axles and maintenance are a bit of a pain...
During the week I tried to use the axles off the Mantis....the links on the rear just would not work, I banged my head for days trying to figure out why. My only resolve is I have VP metal uppers on the Mantis axle...only difference I see. A fellow crawler reminded me of the different geometry. it had affected the rear shock and link length....well the mantis had no rear shock and it's own unique rear links, so I never noticed. Long story short....had to fix the purchased rear gear issue....did that. Got to try the internally limited 90 mm BigBore. Shocks measure 83 mm eye2eye.

This is what that looks like

Looks a little better, lower, .....maybe could stand a little lower?
Springs are too soft. Need to stare at it for awhile I think. Found
Another set of Egressors....I will try the cut down mod on one set.

I think I'm back on track.....been a nasty week for me
Thanks for checking it out

Looking a lot better... I wouldn't change the springs... when "at rest" do the BB shocks suck down at all? And is the wheelbase closer to spec now?

Yes they do but just a little. Like I think they should. But When I push down they don't return to that point though, maybe half way. I used a 40wt oil, didn't have any 50, all 4 shocks act the same, no bias there at all. I laid the rear down to the last hole and did not use the wedge piece as that moved the hole back 3 spots and raised the rear up a little. After starring at it for a while I think I want to try the wedge.
I have to remind myself that I haven't tightened anything down yet either
Wheel base is 12-3/8"....nice :mrgreen:

Another option that i was just reminded of is you can adjust the limit rod too (the wire going through above the pivot point) by moving it to the middle hole.

 

[Postclanker]

Wouldn't you want as much travel there as possible? And that would only limit the "Hulksta" shocks anyway wouldn't it?

Amazing chassis Dan "thumbsup"

What do you think of a brace between the two rear shocks? I don't think it would hurt the geometry and might add a bit of strength there....just thinking out loud.

 

[Curcal]

That would limit your squat when you dig. Youd "bottom out" on the cross brace.

The steel rod is the limiter for the feature, by changing into one of the 3 holes it offers height options.. You may need to do a little clearancing for the shocks on the bonnet though.

I dont have bracing in the rear between the shocks because i wanted it open so upper links can travel nicely there for guys that need it... strength is no issue with 4mm of carbon on each side ;-)

 

[Postclanker]

Ya, I looked at that again...it's fairly stout back there.
As far as the front brace, you would think you'd want as much travel as possible right?

I hooked up the shock mounts in the rear and that made it sit up a bit, but I like it better, also puts the shock angle a bit straighter or square to the chassis, not such an angle from the axle top to the side of the chassis if you will.
The straighter the better??? Or does the angled shock act the same? Doesn't seem that way to my uneducated mechanical mind. :mrgreen:

 

[Curcal]

Post pics of what you got going. I dont necessarily understand.

 

[Postclanker]

I tore it down last night....

if you can imagine the shock not attached to the chassis, but attached to the top of the axle....without any spacers on the top...the shock will make about a 50* angle to attach to the chassis....if I use enough spacers on the top mount to straighten out the angle closer to 90* then there's a fair amount of spacer on the top of the shock to the side of the chassis. I've always spaced it out on the top on my scalers to close to straight up instead of angled...wondered if this is the way to go with a pro chassis. I think it works better if closer to straight.

hope that's not too confusing...I'll try a small sketch tonight...can't do it from work.

 

[Curcal]

Most everyone spaces their shock away from their chassis. The reason i have found most do this (including me) is to prevent binding at the rod ends. The shock definitely wont work correctly if binding. I'm unsure if you'd be able to measure the difference in functionality between an angled shock versus straight up and down. Remember the shock already lays back towards the center of the rig anyway.

 

[Hulksta]

Yep as Curcal pointed, you want them not to bind and some rigs will bind if they are leaning in too much.. also i like to have them spaced away from the chassis, i find the rig more settled and predictable... On the rear i run the sliders, up front i had a 10mm spacer.

Just Throwing these out there

They came in the mail yesterday

 

[Stuck]

Bling Bling
Those are some sweet axles you got there Clanker. Are those going on the Riddler ?

 

[Postclanker]

We are certainly contemplating that at the moment. Some differences with this and the XR axles...still wrapping my head around them. always wanted a set...reading up on them now.

 

[Hulksta]

Those axles with the Riddler is a winning combo "thumbsup"

 

[FLOKI-81]

you will need the dlux loaded dize weights with those very very very cool axels..
you get almost 200g inside each front wheel and around 50g in each rear wheel..
the weight so low and so far out is a great combo..
Makes a extreme stabil crawler.

 

[Postclanker]

I really like them a lot....I have the front weights, but not the rear, was looking at that on DeLux's site....
Was also looking to see how you mount the servo mount to the axle. In pics I see it looks like it's been screwed into the axle tubes...is this correct???? Seems like a good way to screw that up if so...or am I missing something?

They came to me already assembled...and it appears that's how they are delivered from Eric...but the front axle seems tight...wondered if this is normal?

I've ordered some new links from the man "Mr Links"

I also cut down one of the Egressor shocks :mrgreen: seems to be acceptable length....although it seems that these new axles have a wider link/shock mount location than the XR axles do...which means more angle to the shock...we'll see.
Always a challenge this hobby...gotta love it "thumbsup"

Thanks for all the help "thumbsup"

 

[Curcal]

The link mounts dont look like theyve been drilled or tapped. Put everything together before you drill and tap those. Leave servo mount for the very last.

If your interested in more pointers i can help just not right now. Send me a pm.
