Hello comrades, today I decided to post this quick build, a 12.8 cm FlaK 40. I'm not an expert in anti-aircraft weapons, so it's pretty basic. I tried to install a realistic cartridge ejection system on it, but after several tries, it didn't work. I could. I hope I can edit some codes for autopointing in the future, but for now it has a movement with speed and semi-realistic angle (I suppressed the right angle a bit).

Some details of this simple construction.
I built a recoil system, although after adjusting it, sometimes I could miss (at maximum angle), and the barrel will fly out.
Edit the time of the projectile so that it explodes at 3 and a half seconds, I think that the projectile reaches a functional ceiling of attack.
It shoots 20 rounds per minute approx. I was adjusting it to make it similar to the original.
The structure is not affected by the recoil of the guns, even if it is strong.
The original model used a 128mm caliber, but this one a little more.
Greetings comrades!
