Your welcome guys. I just figure it's best to be informed and spread the word so everyone can get these setup in a timely manner.

I don't have pics of my build yet since i haven't really had time to start on it. But RcBro is right. Looks like you still have a proto version. One the production version that I have, the upper link moount portions of the chassis go straight up on the sides and they don't come in towards the trans on the top. It did not come with any spreader bars, but it did come with 2 braces that run length wise between the two "link towers."

If I have time I'll try to at least take some pics of the included pieces and a nice side shot of the chassis plates so you can see the difference.

HBRC · 06-05-2009, 04:49 PM

hmmm, no mention when I bought it that it was not the production version...

sent DNA an email...

edit---

DNA is awesome. already got a reply, and they'll send new chassis plates!

As promised, some pics of the kit and the revised side plate design with braces.

So these are in production now or still in proto testing stage?

Well after what I've heard from both Don @ DNA and Robbie @RCHQ, via email, these are the production version.

HBRC · 06-07-2009, 12:24 PM

I got mine from RCHQ, and got a preproduction version. If you order from them, call and verify what you're getting...

Mine also came with 4 bent links, not 8. DNA is taking care of me though, so I'm happy. (still not clear on how many, or which were intended to be included. I've heard 4 bent links come with it, for uppers, but no lowers...preproduction chassis isn't supposed to be for sale, but RCHQ has them pictured, and shipping...) I used the bent links for lowers, as they fit the profile of the chassis perfect. I don't wanna bend my own delrin links, or use straight links and have them below the chassis. the included links got me at exactly 12.5, with my custom top links.

and by the way, I ran mine yesterday for the first time, and it does extremely well! It's not too different than my typical droop for driving style, but does have some 'unique' characteristics. Oh, and the eritex dig fits awesome, and keeps it super light. I gotta take a bit of weight out of my front wheels and see how light i can go and keep the droop effective.

Update...here's a few pics from this evening. That's right...it's 11PM on a Sunday night and I'm still at it to make sure new stuff is coming your way

This revision is finally addressing all of the issues I felt needed to be addressed to make this thing as good as it can be. Here's a list of what changed.

New upper braces keep the axles from folding under the truck on falls preventing the snapping issue
Side plates have been beefed up around the lower link hole to further prevent breakage
Upper link mounting location has changed to move the chassis sides out of the gear area
More upper link mounting holes (which were very needed to aid in adjusting geometry depending on how heavy you run your rig and where you COG falls)
New chassis design/upper braces remove the need for a stiffener between the plates allowing more/smoother articulation (still optional to help cut articulation down if desired). This makes it so the lower links/torsion rods can attach a little further out on the axles without losing necessary articulation thus eliminating axle sway
GC with Rovers is set at a hair over 2-5/8" with NWT reach up front and squat out back

On to the pics

That is one sick looking roller you've got there!!!! To bad it's gonna get all scratched up:-( Nice pics too.

bigflex · 06-08-2009, 06:53 AM

good color combo!;) I thought it was gonna sit closer to 3" GC with tall tires?

Thanks guy, no on the GC. Testing showed that the added height made the geometry not work correctly. I actually brought the height back down a little from the last revision of the chassis to fix some of the geometry loss. Keep in mind I'm running short foams in the rear so I'm losing an extra 1/8" or so there.

gotcha. I guess it wouldn't be that bad. I am just so used to running my CFX at 3" GC with panthers. Just have to change my driving a little. No big deal.

Looks great Bro,sounds like you been doing alot of testing

I'll post a vid this evening.

Available in our store and heading to other dealers/distributors this week and from now on

Here's a short vid, still working on pulling together more vids from the vid files taken recently.

Nice!

Looking forward to getting one put together.

kineteks · 06-10-2009, 10:28 AM

Don, I noticed that the link mounting points have moved around a bit during development of this chassis. I'm trying to finish mine up, it's the "production" version it seems although I got it before it was released officially. The lower torsion arms were mounted completely inboard of the Axial axle mount in the last iteration of the prototype but I see the production release images have the torsion arm back inside the axle mount. Which set-up is a good place to start?
Also, the top links at the front axle were on top of the axle link/battery/servo plate (good for BTA steering clearance) but the latest glamor shots have them underneath. Is that the currently preferred set-up or can they still mount up top? Top mounted puts the ball-links in bind on any of the lower mounting points at the chassis and would get worse as the suspension compresses, so that's a reason to move them under the plate, space for the drag-link gets pretty tight though. Any suggestions?

billet works · 06-10-2009, 10:45 AM

This new version was designed to work best with the torsion rods back between the link mounts on the axle instead of inboard. The vid uses that same setup. You still have plenty of flex but less axle sway with it now.

Without lowering the servo mount (by modding the axle case - cut the risers flush with the top of the pumpkin) I like it setup under the plates. Drag link is tight but if you run your bolts up from the bottom there is no clearance issue if you use a long servo horn. If you decide to run them on top you can just space them up slightly or use the bend in the links to get you over the mount.
