As you probably already know, the T-50-2 is getting replaced by MT-25 and moved to tier 6. This is how the transition looks in the 8.7 tree

First, let’s have a look at the 8.7 tier 4 light tank T-50

This is how it looks in 8.7 (elite, modules)

At first glance, compared to the 8.6 T-50, following was changed (in elite configuration):

– speed limit nerfed from 60km/h to 52 km/h
– weight increased from 12,68 to 13,95
– turret traverse speed buffed from 45 to 48
好吧,大概看了下T-50的改动:
极速从60砍刀52
重量从12.68增加到13.95
炮塔转速从45增加到48

Until it gets entered to gamemodels3d system, we won’t know more.

The MT-25 is a new tier 6 light tank, unlockable from KV-1S, that continues the line to KV-13. Here (modules, stock, elite):
然后MT-25作为替换t-50-2的产品, 居然要从kv-1s出!!!!!
还没有t-50-2的童鞋你们要赶紧了!!!!

Compared to T-50-2 in top configuration, MT-25 has following changes:
