Dora guns mounted in Jello?

[GRUNHERZ]

Typical.

Well, I dunno....

I just saved the D9 image of the cannons, and the A8 image of the cannons then pasted the A8 image into the D9 image so I could see both planes side by side.

You are definately on target with the distance from the planes.... but I don't think that the Dora sits much higher on the ground than the A8. In fact I'm almost positive they have the same landing gear structure.

Anyways, when I pasted the A8 next to the D9 I found out something peculiar... that being the D9 shot gives you a view as if you were watching the plane in level flight from directly in front of it. In other words, it's facing directly at your point of view, and you can't see the rear fuselage structure at all.

BUT in the case of the A8, you CAN see the tail and a bit behind the canopy sitting behind the plane.

What does this mean? In the D9 photo you are firing almost directly at the screen, in the A8 photo you are firing much lower.

Hence, as stated before, this gives you a percieved vast difference in dispersion.

Don't believe me? If I could find a place to host the A8 pasted into the D9 photo I would... but geoshitties doesn't let you link images to be viewed unless it's linked from a homepage in their site, and MSN communities is a lost cause.

Someone else want to host it? Hell you can do it on your own... just make sure you line up the top of the chat bar.

I just ran some tests myself, and I have to say that it looks like Pongo is correct.

Just slight variations in altitude result in tremendous apparent differences that are not actually there.

To run this test properly the aircraft would need to be positioned so that the viewer can be placed at a fixed location.  E.g. the aircraft is at the end of a run way and the viewer is positioned on the surface of a hill.  Even this test will still be subject to the vagaries of the upward angle that the parked aircraft imparts to its guns, e.g. a parked P-38 will fire at a much flatter trajectory than will a parked P-51.

This is why I never test anything. I still say something is screwy, but there's not really anyway to prove it unless I get a terrain with a vertical wall and a range finder.

[AKSeaWulfe]

Raub, are you saying that what I'm seeing I never should of brought up?

What good is a test if it's inaccurate? Believe me, I would scrutinize my own stuff to make sure I didn't make a booboo somewhere.

You can clearly see more of the aft section of the 190A8 than the D9, which in turn says that the test is false because that means the angles aren't correct from the aircraft to the viewpoint.

SeaWulfe, why don't you pull the stick out of your ass. Why are you guys so defensive? Why does everything always have to be about you? You and your buddie DejaVu have some sort of persecution complex, thinking that everything is directed towards you. Get over yourself.

I was trying to say that I never run tests, because I can never come up with definitive answers. I couldn't figure out how to do it without any variables. That was the best I could come up with.

Seawulfe - you and Deja need to start a new club.

Call it "the we are mad club."

Or better yet, "the are mad, and we didn't read the posts before we starting acting imperious club"

2x in the past 2 days I have seen one of you try and squeak raub out for agreeing with you.


That said:

I thought about what was posted, and I think you have a point, but I find the screens odd.  Here's why:

The dora has a longer tail section.  Given the same height in landing gear, this would make the angle between the ground and the gun flight path smaller than on the A8.  This is simple geometry.  Then I checked a book, and the A8, at 3.96m, is actually noted to be taller than the Dora at 3.36m, which would increase this effect even more.

This would make the dora shoot further under the camera, and decrease the impression of dispersion, while the A8 would be shooting more directly at the camera and enhancing the effect.

In these screenshots, the exact opposite is happening, which is very odd.  You could factor in the angle of the ground, except that the camera view is based on the aircraft in relation to itself - not in relation to the ground...

So...

I'd say we need to test some more.

Perhaps some films of the two aircraft in level flight firing their guns, which could then be paused and viewed from different angles are in order.

[Pongo]

Kratzer.
You might as well ask.
Why would someone make a mistake?
The end of the shadow is visible under the D9 but not the A8. As the nose of the D9 is longer(tail length would seem irellevent to me) It would seem more likely that the end of the shadow would be more visible under the a8.
Its easy guys. take a long external  rear view of both planes in the TA and blaze away. The rounds never leave the bounds of the original dispertion of the weapons on the AC. If they did it would only be at over twice convergance. So the real puzzle is why is that screen shot wrong.
I could only make the spread look like that by approaching the boresight of the weapons. So I looked again and thats what the poster did as well.

I did test this by making a film and viewing it from different angles.

Refuting your dispertion claim does not mean that the dora does not shoot low though. I dont notice that it does but I adjust my head position in every ac.

My point exactly.

As to why the length of the tail section of the fuselage matters, it is because it places the tail wheel further from the front wheels, which decreases the angle from the ground of the fuselage overall.

A surefire way to do this test is to use the F5 view angle and zoom in or out so you can get what you need. Then just use the view keys to pick a viewing angle and have at it. I'll check this later tonight or tomorrow and post pics. If someone else wants to back me up with this by doing the same thing, by all means do so. It sure beats trying to figure out a .0000071 degree pitch change in pics.

F3 view -> zoom out fully, press and hold 2 on the keypad, then fire away. A-5, A-8, F-8 and D-9 all look the same to me.

Another way to test it is from the inside.  Set convergence of both planes to the same distance, preferably the longest distance possible.  Then fire the weapons of one aircraft, and from the cockpit view physically mark the boundary of the bullet/cannon groupings on your screen.  Next, do the same with the other aircraft, and observe if the grouping stays within the other aircraft's boundaries.

I didn't see much difference with those..

but those lasers in P-51...
does those things disperse at all?

 Hey... I have a question? This whole thing is based on the "pixels" your seeing. How do we know that the graphics you see in game actually even relate to whats happening in the data? I havent played for long but it seems the eye candy doesent really need to always relate to the actual data/guts of the game....?

batdog

P.S. The test seemed okay to me. Its certianly not perfect as in taken from the perfect angle each time but it gives you a general sight of what is happening it seems. This seems to go with peoples personal experience with the plane as well?

try shooting some level flying plane next time from 400 yards so that convergence meets at the target.
you will see hit spires all over.
