Hello
I am about to begin a build for the 1/35 Zvezda BT-5.
Are there any aftermarket tracks for it? Also, Bronco, Massterclub and Friul make tracks for the BT-7. Could these tracks be used on a BT-5?
Thanks everyone for your help.

If the aftermarket tracks are intended for the Tamiya BT-7 Model 1935, they should work, as that version used the original BT tracks, which had plates that were nearly square. The later BT-7 Model 1937 variant used the shorter-pitch track, which had a different drive wheel (technically, it wasn't a drive sprocket, as it had cogs, not teeth). This link has a photo which shows rthe difference:

The Zvezda hull is a little long, but it can be shortened with little fuss, as it is assembled from flat plates.

Thanks Gerald!
