Yes, very sense.
Although the T-129 is a good platform, she has insurmountable flaws. First of all, there is no room left in the body of the helicopter to upgrade the avionics. Secondly, the 20 mm automatic cannon looks makeshift.
As the third, the ammunition strip is very delicate and very sensitive. The automatic cannon will not work as a result of any shrapnel injury in this strip. Additionally, this sensitivity makes loading ammunition difficult.
The body of the T-629 is almost ready. There will be no delay.
