BK 3.7 has bad RoF in IL-2 game, in real has 160 shot per minute in pratices not 80, as in IL-2 game.

US gun camera film ran at high speed, 4x real for more frames to catch the action.
On playback at regular speed all things happen 4x slower.

What frame rate did German gun cameras use? 1x?

It could be just my impression but the BK 3.7 on the Bf110 fires at a higher rate than the one on the Ju-87G. So might it be that the Bf110 BK 3.7 fires at the correct rate?

real ROF of BK 3.7 is 2.75-3shot per second (via video on top of the page), i did some tests and BK 3.7 on Bf110 has 80 shot per minute, and BK 3.7 on Ju-87G-1 has about 70 shot per minute, I thik that is quite disadvantage for "blueside" becaouse they have not, any other primary antitank wepon, and I dont know why isnt simulated more corectly

Hmm... I made this same report about years ago, no respond, nothing was made. Hopefully it's not too late to fix this in patch 4.09. But think, what if some other weapon, like M2 .50 cal machine gun suddenly had two times lower ROF than it really had? Would that be fixed?

IRL, the BK 3,7 was simply just a FlaK 18 modified for aircraft use and firing either HE (Bf 110) or special tungsten-cored Hartkernmunition high-velocity AP - ammunition (Ju 87).
If someone's thinking "no way such a big weapon could fire that fast":
-The russian NS-37 of approx. similar power and shell size fired 250 rpm
-FlaK 43, an improved AA gun version, fired 250 rpm
-HECK, the game features the HUGE 50 mm MK 214 gun on ME 262A-1/U4, which, fired 160 rpm!!!

Simply 80 rpm -> 160 rpm, and that's it.

http://forums.ubi.com/images/smilies/11.gif to Oleg and team if you fix this. It couldn't be that hard, could it?

Hi

There where 2 versions of the BK 3.7cm.
One based on the FLAK 18 and one based on the FLAK 43.
The later had a higher rate of fire and was used in the Me 110 and the Me 410 after 1.6.1944.the test where positiv and 3 x110 and 2 410 were equiped with this gun.
A Me 410 was send on combat (dont know what target) and was shot down Wrknr 10241.

The 110 and 410 could also be used in the groundpounding role.

The gun (BK3.7) could fire the following rounds
3.7 cm -H- panzergranatpatrone L'spur ohne zerleger (Hartkern Wolfram)
3.7 cm- panzergranate L'spur Ub ohne zerleger (traininground)
3.7 cm -M- panzergranatpatrone ohne zerleger (M stand for mine iow it has a explosive charge)

Ohne zerleger means no selfdestruction



cheers

Sorry but on 45k (at best of times) dialup here so I rarely d/l video.

I don't know the real speed but am interested however it goes.
I did read at CWOS that the one we have should be pointing down and have a seperate gunsight.
Perhaps it would have been better to have a different version of the 110? Oh well!

Hmm ..to me it seems strange they would get the RoF wrong after going through all the work with implementing and researching it for both 110 and stuka.

you have right BUT, mainly change between Flak 18 and BK 3.7(what is based on Flak18) was cutoff, it was lighter then cutoff of Flak18 and it meens that ROF was higher, about 120RPM of real ROF not theroretical. BK which was based on Flak 37mm typ 43, has about 160 RPM real ROF...

Just to give this a bit of bumpage...

1c team need to fix this aircrafts guns.

Stuka G1 is now the most unused airceraft in our I/KG26 hangars since some patches back, something went bad with those Bk'shttp://forums.ubi.com/groupee_common/emoticons/icon_frown.gif

Heres some film of what we should have with IL2 1946 Ju87-G1, Ground & Shipping attack. Ignore sound as its likely to have been added at editing.

Sorry but no tracks or charts just film of Rudel (apparently).
