That's not consistent with my experience in real life or any of the other helicopters in DCS (including the AH-64) before the patch a couple months ago. The hunting behavior of SCS at 0:26-0:40 is simply not correct. During that time there is zero movement of the collective. I've never heard of PIO yaw in any helicopter, ever. It's not a thing that exists in real life. In fact the heavier a helicopter gets the more impossible it becomes. There is just so much momentum that heavy helicopters have you could never induce such a thing because the tailrotor does not have that much authority relative to the mass to move like that. It's not about "smaller" movements the physics are simply wrong. I repated the flight with the SCAS yaw disabled and the oscillations are gone but the forces are still all wrong. There is a large, unnatural yaw force that turns on and off at 20 knots. If you constantly go between 18 and 20 knots, you can get the helicopter to oscillate if you hit it at the right frequency. This happens regardless of torque setting. There is another unnatural force, smaller, above 27 knots in the other direction.

Appreciate the comments but you are missing some things here: First, note that the green line in the control diagram is SCAS, the white line is my control input. 1. I am generally not doing more than 200fpm changes with the collective. The wild swings later in the video are because of the excessive movements of the tailrotor. At around :07 second I make a "big" input into the collective to increase to 400fpm without pedal input. SCAS makes a large correction and there is no felt yaw (correct behavior). At :12 I stop climbing by reducing collective and apply right peddal. No yaw (correct behavior). At 0:17 I arrest my descent and the incorrect behavior begins. My nose should come right as the helicopter bites into the air and stops descending. There is no yaw (incorrect). At :21 SCAS (without my knowledge) is inputting maximum left yaw while the helicopter is no longer climbing. The helicopter's nose swings to the left. (Incorrect behavior the left pedal should not have that much authority and the helicopter lacks momentum). I stabilize with right pedal. (Correct). At :30 I initiate a slow gentle climb (50fpm) I expect the nose to move left, it moves right because of SCAS (incorrect). At :40 I stop climbing and drop the collective expecting a big movement of the nose to the left. It occurs but is significantly delayed. I should be able to counter the leftward movement of the nose with collective. I cannot and I need big movements in the pedals to stabilize. (Incorrect). I'm also approaching 30 knots and ETL so the pedal movement should be damped from early in the video. It is not. (Incorrect.) At :50 I make another big input collective input. Delayed yaw with the wrong force 2. I'm not chasing the yaw. I've never heard of PIO in the yaw channel with pedals. This behavior is not present on any other DCS helicopter nor in real life. Here is a video of me doing the same thing in the OH-58. This is a lighter helicopter in cold weather. All the behavior here is correct.

I made a quick video on this yaw instability. I am attempting to fly around 20 knots forward as if I'm trying to line up for a rocket shot. I'm am below ETL and flying by hand. I am making slight changes in the collective to navigate above trees and obstacles. Very small changes in the collective cause wild yaw moments. You can see how active my feet and yaw SCAS are during this short video. The oscillations are very difficult to control. There is no wind here.

This video at 1:43 has the only image I've seen of the F-35's signature management system (Vertical Situation Display). It also shows the ground collision avoidance system pulling 18Gs. Also has DAS highlighting IR plum from AA missiles.

It's most noticeable with power changes at low speed. It seems SCAS isn't damping yaw as much as it used to.

I'm getting a bug where George can "see" late activation objects that aren't yet activated.

The hold modes feel a lot better with the latest update. Didn't really notice the other changes too much.

There is a tutorial on the M4 in the training missions list. You need to click on the gun, then switch your mouse mode (Alt+C).

No voice. Only text.

This is much closer to how a real helicopter should feel with stability augmentation. The Apache is extremely tail happy with SCAS on.

I wish we had an AI that just manages the MMS. I really just want to fly, not manage sensors.

The trim ball actually functions unlike the Apache. I find the vibration a good indication of ETL which makes it easier to know when to add or remove power. Tail rotor feels much better than the apache, too.

I just took a flight and this thing right out of the box is flying better than the Apache. That's wild. Especially when it comes to the SCAS. I seem to be doing a lot less fighting the SCAS.

ATFLIR because it looks better.

I'm still downloading but has anyone tested the new flight model changes? Particularly the high AOA and PA mode for carrier landings? https://www.digitalcombatsimulator.com/en/news/newsletters/2e25949d76e12cdc0862b99a0e41f0ca/
