first off i want to briefly explain what hit boxes are.
imagine the Attack Chopper is a giant flying box and if you land any sort of projectile explosive (tank shell,RPG, SMAW, SRAW,boat shells) in that box then chopper goes bye bye and it counts as a hit.
what i want to talk discuss is how abnormally big they are compared to BF3.
in BF3, unless you directly hit the chopper your RPG/SMAW/Tank Shell missed. now if you look at my clips there are some where i do actually hit the chopper but then there are others where i should have missed by BF3 standards yet still hit it and got the kill.
there is one clip that was uploaded by PissPawz maybe a week or two ago that really stands out to me. he was on a Naval Strike map playing conquest, the AH was diving and he fired his RPG and got the kill. now, i don't always notice in other peoples clips if the RPG/SMAW/SRAW/whatever made contact or should have missed but in this clip i couldn't not notice it. on my TV, which is 34 inches, the AH was on the bottom left hand side of my screen and the RPG was fired around the middle of my screen. i don't know if the AH hit boxes are just fucked when an AH is diving close to the ground or if it was server side lag/ping issues but man that was nuts. i know in BF3 there was a guy who had a really bad connection so sometimes he would directly hit a chopper and just dust it thus why i mention that.
in a lot of my clips you may notice that i don't always make direct contact with my RPG's i just get lucky enough for them to be within the hit box. i don't know if they have made them bigger or what the exact dimensions are but i hope they decrease it. it is still almost impossible to fly AH's unless you play Air Superiority and i find it quite aggravating. that was one of the most fun vehicles to use in Battlefield.
it isn't so much because you could get a great pilot/gunner team and just shut down and entire server but because the learning curve is so massive. it takes a long time just to get good at flying, taking off/landing/etc, and then maneuvering and then actually killing people and finally putting it all together, not to mention learning how to fly and stay alive on each map presented it's own set of unique challenges. to me, nothing in Battlefield is as rewarding as the culmination of all your AH skill's coming together and having that first game where you and your gunner or you and your pilot shut the server down and knowing you can do it again any time your team needs your backpacking skills.
