Thanks for posting very nice video

To answer your edited question , no need of any modification to the tracks or sprockets, they just fitted naturally.

Thank You very much for reply - Yes in the begining I asked, but noticed that You have already wrote that they "fit perfectly". So no additional question was needed .

would the heng long metal track for the kv-1 work on a tamyia js-2

I'm going to try the asiatam metal kv-1 tracks as some is-2 used these.

However a big warning, don't use metal tracks till you have reinforced the front end, mine has started to buckle just using plastic tracks after a couple of days running on grass.

Tamiya JS-2 Builds: I purpose my Tamiya builds as IR fighters and for that use I like to usually run plastic kit tracks when possible. I use the Tamiya KV-1 plastic kit tracks on the red star JS-2 and they run great using the JS-2 drive sprockets, no issues. Tip: For the IR red star JS-2 I left the split hatch off and saved those delicate parts for later shelf queen status.

The hull fronts do use a simple home made aluminium brace and a Sherman metal elevation arm from ETO Armor, the only modifications to this otherwise exceptional, well running model. The other two JS builds run the JS-2 kit tracks and are similar IR builds.



Tamiya KV-1 Builds: The two KV-1 builds required custom one off modifications to become superior IR runners as the stock kit hull build up is a dismal runner.

The first KV-1 without markings runs Impact metal tracks and both KV-1 hulls are Daryl Turner Designed metal braced where it counts with his one off custom spring return idler systems; ETO Armor Black motors; Impact 8T pinion gears and ETO Armor gear reduction units for scale speed.

where is buckling exactly

Around the idler mount on the less supported bit of the chassis tub that sticks forward
