Gonna record the video and put it up later, I'll use your description (if that's ok of course).

Sure thing

Hey again, I got some new videos up, check out the main post. I added the Split-S (Reverse Immelman), a double loop video, and a video of possible applications for the Immelman. Enjoy!

um,

nice post, the chopper tactics, good stuff... but how does that video show the M95s power? you killed another sniper with it? with what looked like a head shot? I don't get it, that same shot would be easier with an M24?

Thats the whole point retard. Everyone says the M95 sux. It's not accurate enough. BLah blah blah. You just have to know how to use it(point of the video) and its an excellent alternative to the shitty MEC and China snipers.

*AND ITS AN EXCELLENT ALTERNATIVE TO THE SHITTY MEC AND CHINA SNIPERS*.

yeah, it is. UBAR shows that it does same damage as the m24, at *about* the same ROF, and the same accuracy. yeah, the M24 is twice as accurate and just as damaging. reference above. that and it makes your day when you KO a chopper pilot with a sniper rifle. gunner really just doesnt have enough time to realize whats happening most of the time.

Yup I've seen it done before, circling the opponent with your nose centered on him. I need to learn to do that.

Yea, I've actually been working on this, I've seen it before and i know it's not too complicated, just that my strafing technique is a little messy these days. I'll probably get it by tomorrow. I'm also trying to see if I can get a different point of view than inside the chopper to show people that haven't seen it what it looks like, but that's probably not gonna happen soon.

It's actually easier than you probably think. They key is that you are not on full throttle the whole time. It also invovles adjusting your nose's position to the ground. What I mean by that is that in order to keep a circle going that involves your chopper in the air and in one peice, you can not be constantly aiming down at your target. Also, you will have to aim to the left or right of your target, depending on the direction of your spin (the circling).

I will make a short video soon to show you what I am talking about.


But more on topic: some of those moves are not the most advanced, but useful nonetheless. The most I got out of this post was the barrel roll. I can see this move being very useful when trying to outrun a pursuing (sp?) chopper or maybe even dodging a jet. You are still at high speed at the end of the maneuver and the loss of altitude isn't too dramatic. Combined with trees and other environmental obstacles for cover, it could also be a good way to possibly crash your persuer if he is right on your ass.

I will also make a movie about circling and about other useful tricks with throdle..BUT, I  NEED someone to help me with hosting them online...!?!

I'll host them on my server as long as whatever movie you want to put up is like 2-3mb in size. Let me know if you have the files and we'll work something out. The more movies the merrier!

Ok, I'll ablige with the terminology.  Of course, I flew sailplanes, but I think rotor-winged craft use the same...

Aircraft: Stick Left/right; BF2: Mouse/Stick Left/Right; Roll
Aircraft: Stick Fore/Back; BF2: Mouse/Stick Fore/Back; Pitch
Aircraft: Rudder (pedals) Left/Right; BF2: StickTwist/Pedals Left/Right or KB A/D; Yaw

Chopper pilots might call Yaw something else... but unlike in BF2, aircraft turn by rolling.  If you rolled left 45 degrees, you would be turning... you wouldn't have to roll left 90 degrees and pull up, or use rudder.  In fact... most sailplane pilots put yaw strings on the canopy...  as it is an indicator for the only real use of rudder pedals: to keep you pointed straight into the wind (well... the wind relative to the craft, not relative to the ground).  That, and landing in a cross wind, etc.

Oh, finally, there is no such thing as a throttle in a chopper.  It's called the collective... and you either pull it up or push it down (as opposed to the throttles in most aircraft that are pushed forward, or pulled back).

It all has to do with the design of rotary winged aircraft.  The engines and rotor blades spin at a constant RPM, everything is done by changing the pitch of the blades.  When you push your stick forward, the blades have a the lowest pitch (least lift) when sweeping over the nose of the craft, and the most pitch (and most lift) when sweeping over the tail of the craft...  and causes it to pitch forward.  Same goes for moving the stick in any direction... whatever direction you point the stick in, is the direction where the blades will create the least amount of lift...  while making the most in the opposite direction.  Rudder pedals change the pitch in the tail rotor.  The only difference here I would imagine is with twin-rotor craft (such as a Chinook or Sea Knight), where I guess rudder pedals create an effect similar to moving the stick in one direction for the front rotor, and another direction for the back rotor, and moving the stick foreward and backward changes the ratio of lift between the fore and aft rotors.

Now to the collective.  It changes the pitch of the rotors throughout their entire path.  Pull up on the collective, and they all pitch up, push down on the collective and they all pitch down (or pitch less up... I don't know that bottoming the collective on any chopper will create negative lift).  Now... the collective is actually linked to the thottle, but only so much that the engine RPMs are not effected.  If you pulled full up on the collective without any throttle adjustment, the increased drag of the blades would slow the rotors/engines.  Also, the collective adjusts the tail rotor as well, to compensate for the increase/decrease in torque.

Also... did you know that a chopper can land after an engine failure?  You need either speed or altitude when it happens (so you can't make a controlled landing if your engine failed hovering at 50 ft)...  for the chopper that I saw a pilot do this on Discovery Wings, you needed something like 200ft, or 200kts, I think.  Basically, you bottom the collective (to preserve the momentum of the rotors), and pitch down (to preserve forward momentum).  Then when you're close to the landing spot, flare (pull up, nose above the horizon), and pull up on the collective...  the combination slows your forward momentum, and provides lift to stop you from hitting the ground too hard.

Finally... it may help you to practice and video if you go to multiplayer, then create a LAN game.  No AI bots to fire at you, although you do see the "The game will start when X more players join."  Also, you can select 64-player maps.

Actually circle strafing is really easy with the mouse.

Well, I should preface this by saying that I learned how to fly on Desert Combat, which is a MUCH harder, more unforgiving control system, so I found BF2 controls very easy by comparison to what I learned on. Like driving an automatic after learning on a manual.

But here is my run-down on how to circle strafe. Rather than just explain how it is done I thought I would write it as "How do I teach myself to circle strafe?"

(Firstly, teach yourself high up. This is true of any kind of flying skills. Learn it high up, and when you have mastered it, then and only then do you lower it down and find your limits.)

Get yourself into a steady hover, and then bank left and right. Use just a slight movement of the mouse to do this. Move it until you tilt around 15 degrees in the direction you want to strafe, and hold it at that angle while you move, then tilt it back to level when you're done. The effect is that you slide sideways in the air.
I have my mouse sensitivity for helicopters turned up so that small movements are all I need and so I can jerk the craft around quickly when I need to. Moving the mouse left and right by small degrees without anything else is the equivalent of strafing left and right with A and D keys on the ground.

Now you do the same thing again, but this time, as you strafe, you want to kick the tail around. Press the A or D key, use the opposite one to the direction you are strafing. So if you are strafing LEFT, you are pressing the D key to turn RIGHT.
The key to controlling it is in applying even thrust to maintain altitude, and keeping the mouse movements smooth so that your circle is even, giving your gunner a stable firing platform. When you get good at it, you won't have to do complete circles. For example, strafe around the back of a set of buildings, then apply full power and spin the helicopter around and then drop it down again to put yourself on the opposite side quickly.

Bah...  CH-53's can loop... and that's one of the largest transport hilos ever built (I know it has the largest main rotor... but that's the only record I'm sure on).  Not crazy... just unconventional.

how do u get fraps to record your files at smaller sizes? i mean fuck, i try to record stuff and the file sizes are like 150 gb's. how do i get them to like 20-25 gbs for like 30 seconds of recording?

^^^easy. i can show but fraps records huge ass file sizes. i want to know how to get 30 seconds with at the most a file size of like 25-30 mb's. when i record, fraps records like 150 gb's file sizes for just a 30 second clip.

No, what GotMex meant is the proof of .50cal rounds flying pretty straight, not drop quickly as everyone has stated before. Even I was convinced it was hard to hit a distant target. Now I see I was mistaken. Thanks GotMex for the undeniable proof

Uhh... basic physics, anyone? All bullets drop at the same rate. In fact, EVERYTHING drops at the same rate. It doesn't matter what their mass is, they are all acted upon by the same gravitational force. Read on if you don't believe me.
