Here is an image of the new black anodized chassis for the inline hexapod 3 walkers. The parts are in, just need to pack them up. Give us a couple days. 
Jim, might i say that looks monumentally badass? 
i love the little bumper things at the front, remind me of a Quad or Off road Vehicle
EDIT>>>
A bot post (below) makes me think of something, what if you were to makea rover of this length? with the bumper type things and made with aluminum? i think that might be pretty cool 
Very cool.
Are you doing the tri-track base in aluminum as well? I’d buy that.
I like the slight stretch to the chassis, as opposed to the previous Lexan one. I’m in the process of re-working my Hex-2, and had a bit of a clearance issue between the vertical servo mount and the front of the first hatch in the top deck (almost, but not quite, enough room for what I was trying to do). It all worked out in the end, but I had to get a bit creative.
How does the weight of the stretched aluminum chassis compare with the lexan one, and the SES-based design with an electronics carrier or two?
Simply the best designed products. 8)
I look at the crappy crawlers (Crust Crawlers) and want to puke. Those things are insanely expensive and really junky looking.
Crustcrawlers should not be compared to LM Hexapods, cause LM hexapods would kick butt! 
Sigh, so many walkers, so little time!
Yes, for the main chassis, but the Lexan is a good material for the track assemblies, as the tracks do come into contact with the panels. If they were 0.06" aluminum I can see wear being a problem, but for 0.125" lexan there is no worries of the panels wearing a groove into the tracks.
The current Lexan H2 chassis (HBK-02) has the pivot points spaced 7.0" across and 5.375" lengthwise. The Lexan version for the H3 went through two revisions. The current Lexan H3 inline chassis (HBK-03) is spaced 5.75" across, and 6.0" lengthwise. The aluminum one is 6.25" across, and 6.0" lengthwise.
Here is a comparison of the HBK-02 and an SES-based version. The aluminum one is 12.78 ounces. So there is a slight increase in weight.
That comparison was quite useful. I’d like to see a comparison of all the round chassis, aluminum vs. Lexan and SES plate vs. tubes, etc.

Ok, the lexan and aluminum HBKR panels are compared in this thread. lynxmotion.net/viewtopic.php?p=22348#22348
The tubing chassis info is found in example 5 here. Sorry for the goose chase, but I need to get on to other responsibilities.

Unfortunately I don’t have a real comparison of the assembled items.
Build078 was useful, I hadn’t seen it before.
Thanks,

Hmmm … I definitely would prefer the panels in aluminum. Could you make it work if you gave the track more clearance?
The panel really just needs to hold the sprockets together.
I think you could get away with having just one panel (the inner) if the inner panel was aluminum. That seems to be how a lot of folks are building their custom tracked vehicles. Tanks don’t have an outer panel.
Just some ideas…
