Blackhawk helicopter?

Question

what is the difference between the two different stabilizers that the blackhawks use as 1 is rectangular and the other is rectangular with one side coming to a point like a triangle

Answer 1

its helps it move fast and stablize wen in a dive

Answer 2

to my knowledge, the blackhawk only uses one type of stab

the point like a triangle you saw might've been created because the stab was at full down defection (or up)
