Summary0005758: RPG rocket flies backward.
DescriptionRPG rocket flies backward if launched 30 degrees to the horizon or above.
Wind is not cause of this fly trajectories.
Steps To Reproduce0) Use "[this, 10] call BIS_fnc_traceBullets;" for better view at rocket fly trajectory if needed.
1) Load RPG-7 with exact OG-7V or TBG-7V rocket. Not other types of rockets!
2) Shoot by RPG-7 45 degrees to the horizon.
3) Look at rpg-7 rocket fly trajectory.
4) Look at after some time rocket fly trajectory turn backwards to the RPG-7 man and then hit ground before him in 200-300 meters.
Additional InformationScreenshot show different fly trajectorys of several launches OG-7v rockets.
Right fly trajectories downwind. Left fly trajectories against the wind.

On clear RHS assembly i got the same behavior.

Sorry for off-topic, but it's some nice screenshot, I should say.

Check the bullet cam and you will find that those rockets are falling down with their warhead pointing to the sky. That's because they loses speed, OG-7V has a maximum range of 500m and TBG-7V has a maximum range of about 300m+, and there's no point in a 45 degree firing angle.
P.S. I've checked the parameters in the files, fine and reasonable (since OG-7V doesn't have a motor and TBG-7V & PG-7VR are too heavy for their rocket motor), and the performance of these 2 rockets are kind of realistic.

On site RosOboronExport (Russian defence export):
For TBG-7V: http://roe.ru/pdfs/pdf_2318.pdf [^]
we see: Effective range (depending on the launcher): up to 500m
For ОГ-7В: http://roe.ru/pdfs/pdf_1092.pdf [^]
we see:
Прицельная дальность стрельбы, м:[Effective firing range, m: (not MAX firing range)]
РПГ-7В1 с УП-7В: 700 [There are name of sight type and range 700]

This mean granades TBG-7V and ОГ-7В can fly further in RL then in RHS.

In my test ОГ-7В flew not more then 550 m and then fly backward.
TBG-7V not more then 350 м.
