New Chassis Design
It's time for me to bring my crawler into 2013 instead of 2008. While I love my SWX chassis the skid plate is way to long for me and being I can't drop over a 100 bucks on a new villain or sudu chassis I've decided to try my hand a designing my own. The picture is a rough design I conjured up using my SWX for base measurements for the shock mounting the only difference is the skid plate on my design should be 1" shorter and and around 1/2 in wider to get the spur gear back inside the twin vertical plates. I'll have to make longer lower and upper links for the rear of my rig but the front should remain the same. (I hope) Please feel free to put your 2 cents in I'll take all the help I can get. http://img.tapatalk.com/d/13/06/27/myryga5u.jpg

Nice idea on the tire patch. I bet it would work equally well on the outside of the tire too.

This is my DiY chassis I've been working on please check out these pics and let me know what you think, good, bad or other wise I'd like to hear your opinions.
SPECS
Chassis material is .093 polycarbonate
Stiffeners are 1/8 aluminum
Skid plate is super slippery UHMW(ultra high molecular weight)

It's hard to tell but they are 1/8 of an inch taller and narrower. Unfortunately with all the hardware and the 625 slw they weigh in at the same weight of 5.6 oz

Re: 5.10 The old school shafty

Well, since your asking for opinions: Polycarbonate and UHMWPE are both known to be strong but flexy. The aluminum beams might help, but as they're attached with only a single screw each end, that limits how much stiffness they could add.

Now I don't know that a flexy chassis is bad. Torsion rigs rely on it. But it seems most people brag about how stiff they've made their chassis.

If you decide to stiffen yours, Hobbyking has a pretty good price on 1mm and 1.5mm woven carbon fiber sheet. I've found it to be better quality than some cheap sheets I bought off EBAY.

You might also want to add aluminum crossbraces where you bolt your side beams on.

As for the UHMW Skid plate I hope it will be solid enough being it such a small piece, but you are right it's definitely not as stiff as delrin. After I have tested this design and tweaked it to my liking I plan to make another chassis out of aluminum. Thanks for the imput:thumbup:

Re: 5.10 The old school shafty

In case you don't know...delrin isn't considered stiff either. For delrin skids, they usually make them pretty thick which makes for stiff. For chassis materials, stiff = aluminum, carbon fiber, maybe G10.

Sneek peak of the DiY chassis progress. It's really stiff and suspension geometry is very promising. A little more tweaking and ill be on to the final product.

Re: 5.10 The old school shafty

Looks good man. Keep tuning that thing and we're going to have to find some bigger rocks!
Unshaved Sedona's in the rear for added weight?? Good idea.... haha
I can see you have your braking issue taken care of. There's no way you could have gotten some of these pictures with that worn out goat.

I have body envy! Rock envy as well! Lol!!!!

That's a unique body ya got, what is it?
I haven't comped at Sam lewis Yet but it looks like I have to get there! I'm only a couple hours away in Williamsport.

EPA comps at Sam lewis. I was just talking with crackhead bout rausch creek in a few weeks, on the 17th. Tho sporty might be Fri night. Maybe make it over to join in. Class 2, 2.2p, an a scale poker/dash run(run what ya bring style) even ur sporty is legal for that..

So winner123 what did you think of crackheads mini? I personally think it's bad ass. He has a ton of work into it and it crawls amazing.

I would go pick it up for sure, just for the fact that its diff an looks good doin it!

As for that poor neglected mini work of art, with NO build thread, its pretty bad A$$! Wanting to see it crawl. My eyes needs some video at least!

I'm hoping you guys can make it to a comp... we run 1.9, class 1, an(other then rain last time) 2.2s Fri night.. camping or hotel, then comp Sat.. at rausch with the 1:1 guys wheeling beside us..

Im definitely interested in the comp but not sure my rig is ready to go up against sudu's and villian's. I've been waiting to run into the epa boys out at sam lewis just to see how mine compares to there rigs. Im wanting to widen my front axle but I just spent 100 bucks on VP knuckles and lock outs and chubs.

I'm going to get that body but since you like it so much id like for you to have it if you want it.

Winner123 does the xr mod have any benefit than better steering like does it make a noticeable difference on side hilling?

No worries, no sudo or villain chassis to worry bout.. the worst you have to worry bout is Bwd sss-rs. ;) unless turbofest is there. Then add a turbotech to that..

I'm set with a couple bodies now, but get it. Something like that could go over big for a bargaining chip for someone that just Can't not have it. :thumbup:

As for the XR steering.. mucho benefits! Steering(duh) an reaching for ledges or getting ur tire over a rock an turning the wheel into it for more bite, the list goes on an on... the width adds to stability an keeps you planted, not only on sidehills but helps everywhere. IMO, its a huge win win all around.

Thanks for the info that makes it easier to stomach the 100 dollar loss on the VP 8° set I just recently purchased. But 8 have been contiplateting getting the smooth tubes and just running the 8° knuckles I have cause to be quite honest it's a lot better steering than a stock setup but I just cant use there full potential without going wider caise they bind up in my shocks enough to stop my rig from moving. Pluse another benefit im looking forward to is the xr universals cause the axial CVD's seem to lock up and cause the rig to buck at full lock. How much more than 45° of steering do you get out of the Xr mod? I can get at least 45° out of the setup I have know if I was to use the xr universals.
