Very nice landing:thumbup:, however you were too slow on approach below minimum speeds. Here is a diagram from a RL manual (also ingame manual states the same speeds), higher speeds make it a lot easier:smilewink::

The real L-39 has very sensitive elevator at high speeds, it is even not recommended to use the trim above 700 km/h IAS as it can cause very abrupt response of the aircraft. So if you pull stick to 50% at such high speed abruptly to achieve some Gs you are in for trouble. In real life however, forces acting on the elevator won't allow you to jerk the stick like at home.

:thumbup:

You don't use the "Ublock" button at all. This button is used only for ground tests of the cannon and PK-3 to check its electrical circuits and in real life it is strictly forbidden to use it in flight. This button removes all blocking mechanisms when held depressed (WoW, Speed, AoA).

I am also curious about it.

This might be a correct behavior. Because when flaps are extended to landing position a special servo compensator moves the left elevator trim tab down. So at first there is a pitch down moment from the landing flaps and after servo compensator moves the trim tab down putting the elevator in its previous position. The FFB stick does the same, it also first moves slightly forwards with pitch down flaps moment and then slightly backwards compensating it. Because non-FFB stick does not move this causes the plane to pitch up. Hope it is understandable. This is also described in RL manual and with FFB stick the plane behaves this way. I have a G-940 and it replicates this RL behavior - at first there is slight pitch down (stick goes forward) after compensator kicks in and the trim tab moves and stick goes back and the plane remains neutral in moments. I would moreover add that the left trim tab is animated and you can see it moving down when you extend flaps to the third position effectively moving the elevator up - you can see it in ctrl+enter view. When I disable FFB the plane indeed pitches up, because the servo compensator moves the elevator up.

Yep, it does not work. Once you save it or start a mission those options are removed.

The muzzle is oriented downwards to compensate for pitch-down moment when firing the gun. The whole front part is called compensator and is designed to create upward rotational moment and it is possible to adjust it. I don't know however how well it works in real life.

It works this way in real bird, however it decreases engine N1 (HPC) speed not up to 42% but up to flight idle. Minimum ground idle is 56%+-1.5% N1 and flight idle can be higher as it increases with altitude according to original technical manuals.

:thumbup:

Certainly not :) Good luck approaching at 160 km/h below stall speed :) The yellow mark shows the speed for rotation during take-off. Approach speed is around 250 km/h (full flaps+gear down), flare at 200-210 km/h, touch-down at around 180 km/h.

I completely agree that you will never get the same level of control using a digital input like an analogue. However even when you use digital input, it does not work like no brake (0) - brake (100). When you press the digital brake it takes some 2 seconds to go from 0 - 100. So if you briefly tap the digital control you can simulate light press on the analogue brake and it goes to around 20%, if you hold the digital brake longer it simulates full push. I can steer the simulated L-39 this way absolutely precisely without any problems probably it is even more comfortable for me than having it mapped on a toe brake. Having it mapped on an analogue toe brake differs much more from real life than having it mapped on a digital button on the stick, as far as my RL experience goes.

On a standard Su-25A you cannot even combine S-13 and S-8. You can fire them, but they have different ballistics and the WCS can be programmed only for one rocket ballistics. So you could theoretically fire both of them but the S-13 or S-8 would fall not where the piper aims. Unless you fire them in Setka mode. Other problem is that also pulse generator can be configured only for single rocket type (B-8 needs 20 pulses, B-13 only 5 pulses). Of course newer upgrades are more capable in this, but Su-25Ks from the eighties had this limitation. The same goes for bombs, you never combine FAB-500 FAB-250 FAB-100, because the WCS can have only one bomb ballistics programmed.

Of course you can hang all pylons and the aircraft will fly with them, I was just trying to show what are the common loadouts used in RL operations. I have several friends who worked at Su-25s when our airforce operated them and have asked them about operational loadouts. I also have manuals and there are also some nice books for example from A. Mladenov about Su-25A and its operational use. You don't want to be heavy and draggy in combat, if you want to increase firepower you increase the number of aircraft participating in a mission. You can also review current videos from Syria, where the loadouts are usually very light.

Sorry, but these are not operational loadouts - actually quite far from it. It is rather a diagram of what can be maximally hanged and combined on the aircraft, moreover combining A/T/TM with some really theoretical loadouts. For example R-60 missiles are very rarely used on Su-25A.

:thumbup:, great approach - I just want to advise you that you cannot combine two different rocket types for one aircraft, there is a limitation of the ballistic computer and also pulse generation settings/hard-point settings. The same applies to bombs. You can however combine bombs/rockets, but it is not used much in practice. From what I've read and talked to RL pilots, the most common operational loadouts were (1980-2000): 2/4xS-8+drop tanks, 4xFAB-250/4xRBK-250+drop tanks, or 2xS-25/4xS-24 + drop tanks, 16xFAB-100+drop tanks.

this has also helped me

I am amazed by the rough stick work during take-off and landing in the last video.

Lino, I also thought so - but it is not the case, the beam is the same when the aircraft is in the air. Look here please for situation before landing, the landing light does not help at all (55 metres above the ground): http://forums.eagle.ru/showthread.php?t=153027

Well, also your screenshots show that it makes no sense to use the landing light in this implementation as the landing beam is not only narrower but even a bit shorter than the taxi light.

Autopilot in Su-25T does not work correctly when SL pressure is different than standard 760 - which it nearly always is when using dynamic weather. I've tried to report it several times, but it gets overlooked, try to look here for explanation: http://forums.eagle.ru/showthread.php?t=150622

I am still stuck at 100-200 Kb/s, reverted to HTTP update.

I've already seen it in another Su-25 take-off video and thought it was just some oddity, but now it seems like some procedure. It is strange, because doing something like this in the sim would probably crash the aircraft and the flight manual also does not mention something like, do one stick whirlwind once airborne :joystick:

After some 5 hours on a 100 Mbit optic link, I am still only at 661 MB, now downloading only at 100 kb/s with only 38 peers while uploading at 1-2Mb/s, I think I won't be able to update today :(

It seems that the landing light in my L-39C has narrower beam, however it is as long as taxi lights. Landing light should have much longer beam. The problem is illustrated in following screenshots: Taxi light, wide light beam: Landing narrow light beam is too short:
