Steel,

Like ALPHA says, the suspension arms are still offset, this one being a righty. They are however not in opposing direction like we have described before, and you can see that the road wheels are slightly offset between left side and right side.

ALPHA,

This is the new Leo II metal chassis. I recognized the torsion bar suspension (i.e. rods, rather than plates like Tamiya). I just had a look at mine now and lo and behold, the left and right road wheels does offset each other. Now because they are using rods rather than long planks, they can be pretty tight together since the twisting motion is all containing within the rod itself.

Now I am worry that this is a design compromise. Is this also true on the Tamiya Leo II chassis or even the Heng Long Leo chassis ?

Who makes this Chassis Michael? I like the adjustment mount with the Grub nuts...looks super easy to tune...hope they come out with something like this for the M1 :D

Added note...Rods are more realistic to flat leaf....but I did make the change out on my Taigen PIII hull...made a world of difference ;)

The Tiger and King Tiger are the ones that are in opposite directions that I'm 100% sure of, not sure if any others are or not.

A brand NEW chassis that has just come out is hardly an AH HA gotcha moment.

It's neat looking but as stated they're offset.

Ooops. Sorry ALPHA, this is NOT the new Leo metal chassis that I just received from Carson. The video is dated 2013. I think DKLM version is a lower quality copy of this version. The torsion bar on mine is not adjustable. Also the back plate is a complete replacement of the Heng Long one and this is not that case for the chassis in the video.

Other than that everything still stands........ :-)

Aw Shucks there Michael....had me wishing there would be one for the M1....that adjustment system is pretty sweet...I like the idea of tuning the chassis from the top instead of the side like most models have...you need a bunch of patience to do those ...and on the Taigen it's almost impossible ..even if you have the correct tools

Dated 2013 but it's still for a "new" tank. WWII is old tanks, I'd say anything from 1980ish I'd label as new. New in comparison to WWII tanks.

Regardless of when it was released its still cool looking even if the arms are offset some just for the adjustments you're all talking about.

Looks like a direct copy of the Tamiya leo 2 but in metal. That used rods not plates.

Thanks. That makes me feel much better. And I thought it was only the cheap copies that has to do the offset.

That is a Tamiya Leopard 2 Hull. AFV do an metal strengthening kit for the original plastic tub.

If you watch the video closely you can see the plastic tub is still there, and the AFV metal kit fits inside of it to reduce lower hull flex.
I didn't pay attention to the text at the top. Looked that it myself when I built mine but just seemed an expensive and not needed. The tank is plenty stiff enough already.

Are those what Tamiya uses for retaining the rods? Like I mentioned .,,those things are pretty sweet...and if they are Tamiya...maybe a retro fit to Taigens is possible....Too bad the M1 isn't offset...would make the tank even better ;)
