1day crawler

[Bronco]

[LEFT]today i woke up at 8:00. i was so bored. i watched t.v till 8:30 and went to the shop to start on cleaning the shop. as i was cleaning i came across some old custom axles i had made a long time ago. i set them on the counter and at about 10:00 i had started building my extreme, all preformance, huge, mean, rock eater rig. so the build began,



i had some old alum. i baught for servo mounts. cut it up and bolted the frame together.

next was the 4 link. i had already had them made just not assembled. after that i had to do the shock mounts. since i was wanting this rig a light as possible i made the shock towers out of plexy glass.

2:00

lunch

3:00

back from lunch and started on the tranny mount. im using an e-maxx tranny with titan 540 motors. i mounted 1 side on the frame and then i had to make a mount for the other side(plexyglass). that was done. i gatherd all of my electronics and started mounting them

4:00

after mounting the steering serve esc and the reciever it sas time to clean up. cleande showed my dad and its now 5:20 and theres my 1 day crawler

heres some pics hope you like the beast crawler:-P

You MADE those axles? Totally from raw materials? Cool.
What type of gears are inside?
That turned out pretty good for one days work...

[Bronco]

doh. well the black is a maxx diff. its 98% moded

[DUIdirk]

no drive shafts? Better finish by the end of the day... You may end up wanting a better shock angle, but who knows.

[Reflection]

No offense,but it looks like a days work. You'll need another day to redo the shock mounts,add driveshafts and redo the 4 link geometry so it'll work. Wheres the battery go?

1. the shock mounts work great
2. drive shafts are in (8:42 )
3.whats wrong with the 4 link it works great?!?!?!
4.and the batt goes on the side of the tranny.

1.The shock mounts might work for holding the shocks. It's the location I'm talking about. There is so much angle on the shocks,I'd bet it handles like theres not even shocks on there. Stand them babies up so they actually do something for your truck

2.They are in now

3.The 4 link....it might work for holding the axles in place,thats about it. Just looking at the pictures,I can tell it probly performs as well as a brick does in a wind tunnel Just a rough guess from the pics,it looks like you've got a ton of squat in the rear. That will KILL a shaftie in the rocks.

[Bronco]

oh ok i understand. when i do the shock mounts the shafts will rise. im not worried about them getting hung on the rocks.

[4link4eva]

I agree with raptorman, move the shock mounts that are on the chassis further towards the axles, about 2/3 of the way between the centre of the chassis and the end of it.

[Bronco]

yaaaaaaaaaaaaaa! you guys know it all. i moved the shocks and what a difforence. i made my first test run tonight but i realy need a good batt. all i had was and batt from wally world

Now,study up on link configuration. Redo your links to actually aid traction and weight transfer. THEN,you'll be impressed.

[Bronco]

couldyou give an example?

[Reflection]

Different amounts of vertical separation between the axle and chassis will add or subtract squat or anti squat,but the front and rear are different from one another since the front is backwards. So you gotta use your head and tune it to the rig. EVERY rig will do different things. Theres ALLOT more to it than that though. I could type in this one thread alone till my fingers bleed explaining it all I don't really know EVERYTHING on linked up axles but enough to halfway understand what it's doing and probly make me dangerous . Theres some good threads here about it. Search for "link configuration" "anti squat" "4 link" "roll center" and any other topic that is brought up in those threads. It's not an easy thing to quickly pick up. You gotta sink your ears in it and learn it. Theres ALLOT to it

Theres probly enough info here to help you learn how it works. If you still don't get it.....Go over to Pirate4x4.com and read up on 4 links. Honestly,if you read everything over there about 4 links.....Your eyes WILL be bleeding,no kidding

[ThinkTank]

here is a tech thread on anti squat
Anti Squat and Suspension Tech

[Bronco]

well i read that thread but idk the reason of anti squat. and i also dont know why my 4 link is bad? are you guys trying to say i should have my lower links at an angle?

[RD400]

Anti squat in the rear will "plant" the rear end when you give it throttle. It keeps the suspention from squating and trying to pull the front tires off the ground, pretty helpful when climbing a steep incline. The truck will be more stable and less likely to nose over.

O.K.,first,your not going to understand and learn a linked up suspention reading 1 thread. I've NEVER seen 1 thread anywhere that covers it all. Theres also allot of trial and error. Thats one reason I think some guys just jump on the "stick" bandwagen. It's the easy way out. A 4 link design needs ALLOT more trial and error and tuning to the rig to make it work.

Heres a quick drawing I made in paint thats simular to my current set up.




See the difference in verticle seperation between the uppers and lowers on the front and rear? THAT can play a huge role in your squat/anti squat percentage. THATS why it's good to build in adjustments for your upper,lower or both sets of links on the chassis. You can then fine tune it to react differently.

Take a truck with soft leaf springs and stab the gas....You'll get massive axle wrap. Traction bars can help,but they are a band aid.

Take a truck with a 4 link set up and stab the gas.....Theres zero axle wrap,unless you've got bad joints or link mounts that are flexing under load. A linked up axle should have ZERO axle wrap,period.

Remember truck 1 with leafs? The axle wrapping motion,it's there because the leafs are to soft and they give way. Links won't give,or shouldn't ,but that same wrapping motion is still there. It's transfered through the links into the chassis. Depending on how you have your mounts on the chassis,it'll push up or down on the chassis,hence giving squat or anti squat.

Thats not all there is to it though,theres a ton more that plays into it. Search the terms I gave you in my post above and read into it.

God I love these kinds of threads, real info, not just mouth moving. Great explaination raptorman

I agree.

But you're telling this to guy that took only one day to build a truck.

I'd love to see that anti squirt suspension tech thread keep moving.

Squirt!

[Bronco]

thanks EeePee, 4 1 day its not too bad, btw im a kid tryn to make an ultimate. and yes it is good 2 c an informal thread. tomorow ill make more link mounts. and Ep ur 4 link was my original link idea. but could someone tell me my links are bad?
