Hs-129 Gunsight
 
Is there a guide/tips available on how to use the gunsight in the new plane? :)

I have no idea what each of the angled "cursors" represent or how to use them.

EDIT - if anyone had a document stating some engine boost and rpm settings for cruise, combat, etc I would be thankful as well. :)

I've found some Hs-129 manuals on this site.

They seem to contain the info that I want, but I don't understand German (and the Gothic font in the first one is unreadable :) )

You have to register to download, but there are interesting images included - it's worth a look.

If anyone could translate the first one at least, I'd be grateful :D

angled cursor?

convergence 700-1000m for 3.7/7.5

That's what I use already for those big guns :)

Here are the "cursors" on the left side of the gunsight. Because they are only on the 1942 version, and not the one with the elephant-gun, I think they are an aid for bomb dropping, but I can't figure out how they're used.

According to the German manual you linked it's an aiming aid for level bombing depending on your flight altitude.

1st line: 10m above ground
2nd line: 50m above ground
3rd line: 100m above ground
4th line: 200m above ground

At what speed?

This is unfortunately not said in the manual, but the aiming device was at least modeled with correct angles, stated in that manual too.

So I am curious if you can find out (I never seriously tried).
It should theoretically work better with 6DoF, as then you can perfectly line up your PoV with the plates. But fixed PoV should work also good enough.

1st line: 10m above ground ...

Thats interesting.

I think we have the same interest;) Why would one have a angle for 10 meters, when bombs apparently cannot be dropped less than 20 meters mmm...

I just drop the bombs on guess, and that usually works just fine, especially with columns of vehicles, as soon as the first vehicle passes under my nose at about 50 meters height, the AB-23 will do it's job very good.

Easy solution ;)
Minimum height for Zünder 25 (Fuse 25) was 10m (horizontal)
