you are the one that can understand we are talking about a bolt break , a blade dislocate , fuel leak and..... when something become old it more likely to find fault and stop working and has nothing to do wit how advance it is .
you yourself asked for it
hail new Iranian transport helicopter
AH-1J
hail Iran new Transport helicopter Toofan
hail Iran new transport helicopter Shahed-216
hail Iran bell-214 with no ground attack capability
Looks really good is that built from the ground up or heavily upgraded but either way does look good
