Some more pics!

Absolutely fantastic bird! We're really getting into Modern Air Combat with this classic! And it's always nice to fly a Boeing aircraft: you can figure out the avionics without even bothering to consult the manual. Great, great work Razbam!

Great news from Wags! Enjoying the whole range of products!

Could be very slightly and very momentary here but in that same flight I flew this average speed all along , also on moments that I slightly climbed, in all cases the speed was around the same number. And thus really higher than with the L-39C.

And anyway both fly like a charm, for me the L-39 honestly tops my list, together with Viggen and P-51D!

60% fuel. Very strange: I swapped the L-39C for the L-39ZA and I immediately had better speed 389 kts ???? I see that my AOA is slightly flatter.

Under these conditions (15°C instead of 20°C, lower flight - about 1200 ft) I get about 335-342 kn Still far from a record!

That explains a lot, yes I did most of my testing at 6000 ft; I'll check out flying lower!

Thanks for looking into this Yo-Yo. My best results after a couple of minutes of flight at 106 RPM: About 315 knots / 583 kph

Yes strange indeed! I must be doing something wrong since 1/ no one reports a similar issue and 2/ there is unanimity here you can reach higher speeds! So let's not worry about this; I enjoy to fly the L-39; of course I do not know the real thing but imho the flight model is so extremely well done, it is just simply a dream to fly! What I like most is when you land and take-off you seem to actually "feel" the runway! ED did magic with this kit!

I always refer to knots! As said I struggled, when flying level, to go faster than about 270-290 knots (of course even the slightest dive increases speed substantially). I did some further testing and it seems related to my X-55 stick & rudder settings on one of my PC's. When I fly the same test mission (just flying level essentially) on another PC with a CH stick, I on average reached about 30 knots more!!! I'm trying to figure out what causes this for my X-55 stick.

Do you remember, a trackball was for a very short time a hype on PC. I even bought one, to soon discover it is absolutely not the most ergonomic input device. For one thing, the translation of of curved movement to a linear one makes it a little difficult to learn. Also, you lack force feedback to use it with precision. I can fully understand it is long forgotten in the PC world, and am a little surprised to see it show up in multi million dollar ships!

Yes! I can already say that it seems related to the mission files (I always use missions I made and then modify again and again, so some are quite old mission files). When I just start in a brand new mission in the ME, I now could fly 350 knots level at about 7000 feet, no wind, 60% fuel, no payload. So that is way better as what I have in the missions I was flying. But anyway there seems a wide consensus her that it is not a genral problem and that I am the only one facing this presumed issue. So I'll dig deeper and when I can pinpoint what it exactly is I'll report back!

Strange, no I'm not flying with airbrakes and/or gear down :) I just struggle to get over 270 knots in level flight. I fly without payload and about half a tank. Something must be wrong in my config, I'll try to sort it out.

I always refer to knots. And to be clear: there is no way I can reach 400 knots in level flight with the L-39. But I understand that this is also the case in real life.

Thanks Svtony; if the performance matches the real thing than that is fine with me! Indeed the L-39 engine hasn't much thrust. And I repeat it was just an inquiry out of curiosity, since I absolutely love to fly the DCS L-39. It is an absolute marvel!

Strange that I cannot get these speeds. But I am reassured that for you guys everything seems fine, so I have to check what is going on (on the two different PC's I tested it!)

Yes I also suspected trimming so I tried two things: - trimming to see if I could optimize speed: NO EFFECT - reset trim since it might have been optimal for take-off, not for level flight: NO EFFECT

The L-39 is an absolute jewel and a joy to fly! But I have one question: I struggle to reach a speed of more than 260-270 knots in level flight, as well at low, medium or high altitude. It is only when diving that I can get something like 310 knots or so. (with 50% fuel, no weapons) This seems to me too slow. One private owner of an L-39 claims on Youtube about 500 mph, which might be exaggerated. But given the fact that the L-39 is used in A2A adversary roles and as an aerial cinematography platform, I would think you cannot do this with the low top speed of DCS. In DCS, I can definitely do better with a Mustang, Spit or BF-109. Do you guys also get this low top speed? And do you think it is realistic?

Yes there is no problem to land the F-5E, even if you do not use brakes or chutes it doesn't need the whole runway. I keep having issues with the NWS though, even while simply taxiiing. It seems like Ican only do one turn, then it becomes unsteerable.

I posted a track in this thread https://forums.eagle.ru/showpost.php?p=3272973&postcount=10 In my case I think the problems are related to the nose wheel steering, that seems completely erratic. - and oh yes I checked the bindings.

In my view it is the nose wheel steering that doesn't work. Here a track where it just becomes unsteerable while taxiing for take-off. FT Test F-5E steering.trk

I wonder whether it is related to the problems we experience when braking after landing.

I do have the same issue, over and over again. Make a perfect landing, decelerate and suddenly, the plane veers of to port. In my view this is not a modelled, but a scripted thing. Very bizarre and unnatural. I tried all the rudder and brake setting adjustments mentioned, but to no avail.
