Look at the launchers angle. In red is marked the "correct" trajectory, in blue the actual trajectory clearly visible with the white smoke trail.
Germans used Revi sight to aim and fire these rockets cause they had same trajectory as Mk108 shells, and no matter the convergence cause in real world there was no way to change Mk108 convergence due the mounting characteristics of the gun.

punt !:)

interesting find mandoble. i might actually be able to hit somethin with em if they fly like a mk108:)
-
At a Range of 3,280 feet these shells had a vertical deviation of 25 feet and a horizontal deviation of 130 feet
It seems the propulsion used by these rockets kept them in a "tense" trajectory up to more than 1000 yards.
They had an initial speed of only 1050 ft/sec, slightly less than Mk108 shells, but they kept accelerating after the launch.
The detonation of the 90lb warhead was lethal for targets inside 30 yards range.

Same thing with all planes, dive 90 degrees at near stall speed, hard rudder to a side so your nose is almost 45 degrees to a side... fire rockerts..
they fly straight down.
Or better yet, up with rockets, have someone shoot you up so your tail or 1 wing rips out , as you spin down fire rockets.. they go in the vector of the plane, not where the rocket rails are pointing.
-
Even more, the Wgr launchers were jettisioned after firing, while we keep them onboard :(
-
Good one Mandoble, :)
-
Nice find! Allso, nice info on the jetison, I had no idea of that :)
-
Can fix this at the same time as 109 flaps maybe? ;)
-
Actually, perhaps this is not just for the FW rockets... I have noticed somethings with the rockets in general, which I have been meaning to report to HTC. For example, when I get my tail blown off and face upwards and fire my rockets, the rockets go down, not up. I've seen this with the Jug and the Hellcat.

I just want to say, good job Mandoble. :) THIS is the way you bring problems to light. You'll be far more likely to affect some changes this way, and best of all, it is not a whine, you are presenting some facts.

Rockets will not fly the way they are pointed, Best way to view it is look what happens to a dart when you throw it side ways, it keeps going the direction it was moving, not the direction the point is headed. Most of the vel of a rocket is initialy do to the airplane, just like a bomb drop.
The fins on the rocket will force the tail to be inline with it's vel vector. Hence the rocket will stablize on the intial flight path of the plane.
I would be interested to see what happens when you fire rockets from a real stationary plane like the screen shot.
Not sure that they would have enof vel to be stablize after leving the rail, and in real life I would expect them to head in all sorts of directions.

One other thing the smoke trail does not show the path of the rocket. The rocket left the plane the same direction of the red line.
Do to gravity it created a balistic arc. The smoke trail is a sample point of that arc, and then a straight line back to the plane. Hence the rocket actualy flew above and then back down to the blue line.

Hitech, if u look at the real thing installed in a 190, u will notice two interesting points:
1 - The tubes are vertically angled up.
2 - The tubes are horizontally slightly angled towards the nose of the plane.
These points are well modeled in your 3D 109 and 190.
Why the first and second points if the rockets are going to follow the flight path of the plane instead the launcher tube path?
The INITIAL speed of the rocket was 1260 km/h (not maximum speed) and vectored up by the angled tube. IMO, no matter the speed of the plane (for low and medium speeds), the angle of the tube will be mandatory in the rocket proyectile.
I've read something about a maximum speed to fire these rockets, but dont remember that data. Probably, above that speed the effect u described with the dart may be slightly present.
About firing these rockets from a stationary launcher, well, these same rockets were mainly used this way by the ground forces at ranges farther than 7 km. Do you find an initial muzzle vel of 1260 Km/h enough to stabilize?

If so, the rockets should be seen at least for a second from the cockpit in a level flight launch. In my case, no matter how many times I try to fire them, no way to see them nor the trails from the cockpit sight.

hmmm just took these offline.
not sure what to think. Suppose cant really compare rockets.
-
and this one...
-
Also double checked, at the moment the tube launch angle is not taken into account, it's been on our to do list for a while. Right now all tubes are pointed the same direction as the plane.

Who's?

Sincerely, very good news hitech.
-
In AH Bf-109G6 loses the Wrg-rocket launching tubes when they are fired, rest of the planes equipped with them have them stay on after the launch. As Mandoble said launching tubes had so called "emergency jettison-function". So they could be jettisoned if the plane faced immediate danger from escort fighters. The tubes were reusable, so of course pilot tried to bring them back to base whenever possible.
-
why is it that when a moss loses its wing, you can't fire the rockets, but when say a p51 loses its wing, you can still fire them??
-
I hit a p51 around 1.5+k in a HO once, but be damned if I can hit a lance from 800meters with one, fire and god knows where the damn things go.

your forgetting the R4M.....the rockets fired in 24's off of 262 wings.......blows the hell out of BUFF formations.....proxy warhead
