Need to pick up some track sets (five runs actually, three for an LWS and two for an RSO). Two questions; what's the diff in quality between Modelkasten and Friul? Was there any variation in track type used amongst RSO variants?

On closer look from what I can see they all look the same.

There are differences in what you get. The Modelkasten set also includes new corrected drive sprockets and idlers. The Friulmodel set doesn't. There's also this set:

Modelkasten are plastic and Fruil are white metal,if that makes any difference to you. rR--check this out

Thanks guys. 'Scuze my ignorance but do these sets include links for the whole vehicle or just one side?

Hi Barry,
The sets include enough links for both sides as well as extras in case you lose a few, some get broken, etc. This applies to both Friul and Modelkasten.

I like the white metal tracks. They are easy to put together, and add a scale heft to an AFV. That probably doesnt mean much unless you are doing something that needs a sagging track.

Based on what I've read I surmise that the Modelkasten is a bit better detailed but the Friuls are sturdier when built and are more workable as they're not solidly glued. I'm kinda leaning toward the Friuls at the moment. As the LWS is basically a big solid chunk o' resin this would make it the heaviest model I've ever built!
On a somewhat unrelated note (but since we're talkin' tracks).... what's a 'grouser'?

Grouser usually refers to a metal cleat that attaches to the tracks to provide better traction in snow/icy conditions. Usually staggered or spaced out along the track run and not on each link.

Ahh, now I know. Thanks Bill.

...just finished assembling two runs of Modelkasten RSO links for the kit the kind fellow at the LHS sold me out of his stash... so here's my opinion.

Holy moly! Being a bit picky I ended up cleaning up the wee little sprue gates (three per link) on each of the 68 (times two) links per side. As well, there's a wee little pin to hold them together, 68 time two again...'

Found myself wishing I'd got the Fruils! Well, the MK's were less expensive, look great, and will sag very nicely. The Fruils would have been almost twice as expensive, but a W H O L E lot easier to assemble... haven't recovered yet, as I was up till late putting them together.. thought of going to bed but then thought to myself 'just another ten', again and again...

(As well I'd add that I gotthe MK tracks to see how they went together, learn a bit you know? OK so now I know... oof!)

The Fruils on my KV-1 were sooo sweet! HTH
