Roll on Landing Slams nose to the ground.

[G-Tech]

There are three examples of roll on landing here

On touchdown the nose does not violently fall forward at all, are the pilots yanking back as the wheels hit the ground?

I would say that the devs know this. Getting the nose where you want it is one of the problems the fm has. 
I personally was very disappointed by its performance in the start. It took me a while to get that damn thing to do what I want. 
my one problem is ffb vp force Rhino 

FFB is not implemented yet. Secondly it is more hands on flying in this thing than in the Huey. You can actually do all these things with carefully managements of all controllers. 
I sure grown a lot of respect for the Vietnam pilots flying this thing. 
I come to the conclusion, that it do fly pretty good concidering the lack of very important system. If you disregard the loops and barrel rolls it is capable off now, and concentrate maximum on flying it how it should be. Preferably with high end controllers. You be fine. My guess is this thing going to be very hands off when finnished and almost can be flown with keyboard

Assuming that the center of gravity will be in front of the aft landing gear, it will naturally induce a nose down momentum when hitting the ground if you don't grease the touchdown, so I would assume the pilot might need to be ready to pull the stick back at least some milimeters for a moment.

Keep in mind that the AFCS isn't really fleshed out yet, so any support for ground handling is still missing.

From the TM:

Quote

Two proximity switches are installed, one on each aft landing gear. Each switch is activated when its associated shock strut is compressed during touchdown. The switches improve ground handling by reducing pitch axis gain of the AFCS, by canceling the longitudinal Control Position Transducer (CPT), therefore longitudinal stick input, to the Differential Airspeed Hold (DASH) actuators, and by driving both longitudinal cyclic trim (LCT) actuators to the ground position.

Hi @G-Tech

Can you supply a track file demonstrating what you feel is the wrong behaviour? 

[G-Tech]

I did the best i could reproducing the first landing in the video, with no added input to the stick on touch down.  I just feel like that nose falls and i cant get that nice wheels up landing like a jet can. Maybe there are systems not there yet like above posts said.

Didn't watch the track but tried it myself on the side a bit today. 

I'm not sure there's an issue. The whole maneuver is depending on touchdown speed. I think I touched down with around 60 kts and while lacking the practice (and the DAFCS) to make it look acceptable, I could roll out on aft wheels for some seconds.

We don't really know the supposed speeds for this to achieve and we lack the weight on the wheels affecting the DAFCS.

Sounds good, maximum ground speed for a Chinook doing a running landing is 60 knots.

Good to know, thank you!

[G-Tech]

So Ive tried roll on landings at speeds up to 60 knots, around 20 times. One thing i noticed is that the cyclic is forward quite a bit when touching down , if i center the stick right when wheels down, the nose down effect is much less.

No problem
