Confirmed, exact same behavior observed, under same circumstances : MP, after getting shot down, respawns without changing slot : some joystick control mapping are temporary lost, like the aiming station slew axis and observe button

There's definitely more impact on the tail rotor available power since we witness loss of tail rotor authority while keeping the chopper more or less in a hover ("more or less" due to the chaotic rotation of the bird ), don't you think?

I have a serious suspiscion your Hind is overweighted. If you fly custom missions from the editor, check out you are not near max weight. It's very easy to want to put max payload thinking you need that, while not removing corresponding fuel weight and keep max fuel. Under these circumstances, the Hind will very often behave like you describe. Hot weather, high altitude, and most importantly, higly loaded, you will need to ask for too much just to do basics. These circumstances can happen. A good way to get around these lack of power issues is to take maximum advantage of ETL and only do running, long distance take-off and landing, plane-style. Russian prefer wheeled choppers for this reason, amongst others. Vertical take-off and landing are not mandatory in a chopper, they put you in an unstable, high power profile that you should try to avoid if you can. And little tip to anticipate a possible loss of tail rotor authority : keep an eye on the rotor blades pitch indicator (bottom left if I'm not mistaken). Above 10, you are entering the danger zone, keep your speed and avoid sudden collective change (this should be a rule of you in a heavy chopper anyway, no sudden movement). At 12-13, you are garanteed to have power issues, unless flying fast. Last thing about the "no sudden movement" rule, in a heavy chopper like Hind or HIP with very large, 5 blades rotor, the inertia is real, and the gear-shaft system will struggle quite a bit to keep the RPM of the rotor constant when you suddenly ask for a rotor blade pitch change (thus a change in friction, thus a change in force needed to rotate the rotor). This will transition temporarily the chopper into a bad situation where the system tries to counter the loss of RPM by asking more and more power , reducing what is available to the tail rotor, just to keep up the pace of the change in friction. Avoid this by anticipating all your collective movements and force you to move it slowly. vsTerminus has made a great Mi8 video that shows this (amongst the ton of excellent content he has done on DCS choppers) and shows how to train to stay within proper collective change margins. With the ease to overweigth the bird, many little bad habits can easily lead to what you witness.

Which is kind of equivalent to a 9% dead zone, as the game will deactivate yaw AP as soon as the rudder is off center

As far as I've understood, springless pedals do not work that well with DCS implementation of Yaw SAS , if I'm not mistaken the Yaw channel activates when there's no pedal input, which is detected in DCS when the pedals are centered. So the Yaw channel would be off most of the time with springless pedals. I need to test that theory EDIT : I just tested, indeed the rudder needs to be centered for the Yaw channel to activate

Transmitting on radio is emitting. Spamming radio commands while having your radio on a Freq X will point nearby ADF receivers tuned on this frequency toward the emmitter, AFAIK.

Purely from a semantic point of view, it's LTA when you cannot order enough power to your tail rotor for it to do its job properly (you can't have Authority over your tail rotor anymore), and LTE when you can push enough power to the tail rotor, but conditions make its work useless (Tail rotor lost its Effectiveness). Most if not all of what we witness with DCS Hind is LTA

It's pretty simple to see in-game : get near 14 main rotor pitch and watch your tail rotor not having enough power anymore to counteract main rotor, as much of the power is diverted to maintaining main rotor pitch. It happens consistently, at all altitude, and actually all weight. It's not the result of interaction between main rotor airflow and tail rotor, nor interaction with wind, which are all listed as the causes of LTE in all documents listed above, it's more systematic than that. It's simply a lack of remaining power for the tail-rotor. ED said they were looking into LTE but it was higly complex to model and would require quite some dev power. I'd guess if they had it done, they would have said it. In the meantime, personally, I lighten my Hind so that I never need to go beyond 13 pitch for normal operations, and I only ever pass that limit when in forward speed enough to have forward airflow that keeps my Hind in check (usually when a high dose of lead and/or missile is flying toward me)

If this is all that is needed, then it's not LTE

Lose weight. More often than not, you don't need that much fuel

I'd like to see a confirmation about this, tbh, from ED

Did we even have confirmation that LTE has been implemented?

Did you try to activate the Rudder Trimmer option in the Special Tabs settings for the Hind ? It also trims the rudder on pressing the trim button on the stick, which means you can recenter your rudder once you have trimmed your hind for your flight regime. That avoids too extreme rudder position and leg tension

Overcharged hind + sudden right rudder correction during a hover in conditions already demanding max power (high temp, OGE hover, high alt, etc...) can probably lead to a temporary loss of generator

Wow! Funny I have the complete opposite impression : I find the Hip easier to land, mainly due to the largest wheel placement, making it more stable on ground. OTOH the Hind is to me the most stable chopper in forward flight BY FAR compared to all others. It's plane-like stable, allowing us to make very close formation flying, for example.

Isn't it what Rongor said? "Whenever your rpm gets too low, you can trade in speed for an increase of rpm by pulling the stick back gently (flaring)."

Not quite sure, isn't only one active at any moment, depending on wind conditions?

If you notice, when switching ON the Gyro 1, the upper left ADI gets activated, when switching Gyro 2, the (tinier) lower right ADI gets activated, which resemble a backup ADI to me, hence my guess

Awwww. "Pedal force trim" ? What is this sorcery? Now I'm completely lost in all these trims / AP

I guess it selects which of both gyros (main & backup) is used as a source for the various AP and nav systems

The Yaw "trim" is kind of misunderstood and it explains the behavior seen in your video and against which you struggle. You'll notice that on ED missions, quick missions, etc.... that Yaw Channel is not selected. The Yaw channel is not a trim, it's linked to the gyros and, the moment it is pressed, it will apply yaw so that the nose keeps pointing in the azimuth it was when you pressed it. So imagine you press the Yaw channel ON button while facing north, then turn right eastward. The Yaw channel will apply left Yaw to try to push the nose of the aircraft back north. It's working the same way as the Yaw channel in the Ka50, actually, if I'm not mistaken. I basically don't use this channel. It should be usefull during a missile run, for example, you align on target, activate Yaw AP, and don't have to bother with the rudder anymore to keep your nose right on your target azimuth.

I also added their dampener addon, which adds to the stiffness when spring is removed, the thing may be too responsive without spring and without dampener

Yaw AP was off, I purposefully do not activate the yaw channel But I also removed the spring from my MFGs so my rudder is not auto centering. I'll try to center the rudder and check the virtual input window

Beware, these are purely my interpretations it could be something else entirely.
