Mi-24- The new engine noises are a good change, they sound good the one issue I find is that the sounds at a too faint at a distance at 200m in especially in comparison to the MELB mod, you can't hear it at all when my PC's volume is <50%
I prefer the new YAK sounds, the sounds matches up with the gun and there's a seamless loop in noise, but again i feel that the gun is way too quiet in both the interior and exterior, it gets drained out by any sounds around it
US Choppers- The FFAR sounds are great, i love them (especially from the interior), i don't believe that the same sound should be used in the hellfires and sidewinders. AH-1z's new sound is on the whole pretty good, its distinctive so you can tell what it is from inside a building. The gun sounds are pretty good aswell, good sound quality and loudness. I dont think it should apply to both the AH-1z and 64 since they're two different gun systems
Lastly the Uh-60s sound, i dont know if its just me but i prefer the old sound, theres nothing wrong with the new one, i just prefer the old.
M136 new sound the best change to the sounds, something satisfying of that sudden poomh of the rocket
And lastly the M4, its great, the guns sound less like a pistol, i think they need a little work, the guns should sound more heavy like the AK
