Hello

I and many pilots experienced that the Lavochkin series (we tested La 5 Fn and La7) with droptanks fly as the same as without it. And it wasn't like this before, bit annoying...

"...fly the same as without it." What does that mean? Speed? Turn time? Acceleration time?

I could test it... but I don't feel quite like it http://forums.ubi.com/groupee_common/emoticons/icon_razz.gif

hmm, take a bombs and try La5FN with FULL ELEVATOR. No stall, if you are careful.

That doesn't mean anything...and its not what the original posted said either.

I thing it does. The La5 is plane with limited stall possibility. The same problem was with some US plane in 1st version of PF - but it was solved.


and its not what the original posted said either.

sorry.

Lazy buggers. It takes less time to test than to make a forum post.

La-5FN top speed at sea level.

No tanks: 577km/h
with 2 70l tanks: 565km/h

It makes a difference. Your mother is ashamed of you, Maggi.

I Have no idea what game do you play

BTW, do you think I post topics like this becasue of some other reason? (And they are 80l tanks..http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif )

My problem is that there is no speed reduction after dropping the fuel tanks there should be draggy remains of the hardpoints.

-fuel tanks on
-dropped fuel tanks
-default armament

So logically would be to conclude that Lavochkin has also that different speeds and not the same in all three cases.

That is why I wrote that I don't feel quite like testing it http://forums.ubi.com/groupee_common/emoticons/icon_razz.gif http://forums.ubi.com/groupee_common/emoticons/icon_redface.gif.

But I'll test with & w/o tanks.

OK results are as following;
-with tanks 572km/h
-with tanks then after releasing them 590km/h
-default 590km/h

...and IMO that is not incorrect due to fact that LA-5FN visually looks the same with released tanks and on default armament.
Apparently it has those fuel racks all the time.
Some ac must "l0ad" those racks specially for mounting a drop tank... such ac are 109s for example. So that rack is making additional drag (compared to "clean" version).
Logical consequence to this is reduced speed.

I'll test P-47D27 with 2x500lb l0aded... when I release them, my speed must match the speed of default armed P-47D27 because it has those racks all the time.
I'll come back in a few minutes http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif .

OK here it is...
Apparently P-47D27 2x500lb l0adout gives teh P-47 one additional rack, mid fuselage one! http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif
Hm. Definitely a surplus.
But the funny part is... 47 suffers only 1km/h speed penalty due to that fact!
If we disregard that (surely we can) P-47 has the same speed with 500lbers (after release) in comparison to the clean, default armed P-47.
That verifies my thought about this issue... if there is nothing visual added on ac, it shouldn't suffer any speed reduction after the l0ad0ut release.

We need some details about the wing construction on the la series to find out which modification is done for fuel tanks . There must be pumps and controls lines and fuel lines in the wing and an hardpoint where the amount of fuel can be put on without breaking off or deforming the wing.Additional the fuel lines must deliver fuel at the rate the engine burns it so pump dimension is defined . Most likely the small ammount of extra fuel is for the reason that the wing does not support higher loadings.

For the p47 series just to compare fw losses 7 km/h with etc 501 the newer bombrack with 3 km/h wasnt introduced in il2 series. So might be possible that the p47 has already a streamlined bombrack using 3 km/h but we should really ask some p47 experts about it .

I don't know how you play. But I do know you don't test, and you like to write unsupported rubbish here. You've got some nerve.

Sorry Gents, my tests were online, with chasing A5 1.65
There were such no difference at the red bar, at sea level...maybe the real speed was different, but it was very intresting how could La5FN cathc the Fw with fuel tanks. The test was on Kiev map...
sorry about english

Maybe the La-5FN started with more speed than the FW190 or was slightly higher...or the pilot in the La-5FN trimmed his plane better than the FW190 guy. In situations such as those there are many more variables than if you actually do the straight out speed testing in a more controlled manner.

Then we don't have to have all these silly questions and we can get right down to business and see if there really is an issue or not. I'm all for reporting bugs and performance issues to Oleg...I have many times myself http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Your English is quite understandable. Nothing to apologise for http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Strictly speaking, LA-5FN with tanks can not catch vanilla FW-190A5 on deck let alone FW-190A5-1,65AtA.

Trouble is... if their top speeds are close, winner is the guy who can fly his ac more straight-lineish.
But of course, even more important is the overheat and all those little stuff... like who had more energy/speed at the start of the chase.

IceFire nailed the head of the prob.
