Heavy Nose

[BBQ]

Of course every time I specifically set out to record this phenomena, I can't reproduce it -- but thought I would ask community at large if anyone else has noticed this behavior:

 

When coming to a hover, I'm obviously pitched up to slow down until I more or less stop forward movement. At this point I've got the trimmer punched in and held, so that I can compensate for wind, etc. -- so end result is I'm hovering manually with zero vector, and then I release the trimmer, then engage hover-mode. That's my modus operandi.

 

Lately though, it seems like 50% of the time (usually when I'm in a hairy situation of course) when I release the trimmer, the nose drops a few degrees and I end up moving forward. This is before I engage the hover-mode. I then pull the nose back up again and attempt another trim. Sometimes it takes up to 10 attempts until finally it will hold the nose where it's supposed to.

 

I started to notice this after the 1.2.5 update, which included "Better support for force feedback", and wonder if it has anything to do with that -- as indeed, I use a Sidewinder 2 with FFB enabled. I've tried to also use simFFB.exe to control FFB, but I get the same "nose-heavy" result most of the time.

 

Anyone else notice this lately?

I can't say I've seen that (using a CH setup here).

Looks like it might be related to this new FFB problem introduced with 1.2.6.

I'm seeing this too.

I can only fly with FFB off in 1.2.6

Here's some more evidence:

BBQ, I see and experience exactly the same as your vid. Do you think this is how the trimmer has been modeled or is this something that needs fixing?

[toby23]

My nose drops more than that and it leads to loss of control.

BBQ could you please watch this track and see if its the trim problem is the same as yours.

I'm using a G940 and I'm having such a hard time to fly level like I used to.

The slightest touch on the stick sends the helicopter into a 10-20 degree dive.

It wasn't like this before.

I tried using Sim FFB with DCS FFB off but Sim FFB lost control after a few minutes.

It works for about 30 sconds then stops.

I've not seen this (MSFFB2 user), but something sure seems iffy about FF in late versions. Troubleshooting semi-random stuff like this can't be easy.

 

Toby23: When using simFFB you'll need DCS FF to be on, otherwise you'll get the traditional need-to-center-stick-mode of trim if I'm not mistaken.

[BBQ]

AFAIK you are supposed to set force feedback ON in DCS while using simFFB.

I'll give it a try this evening --

Hey guys -- Im convinced that my issue is caused by my Sidewinder 2 -- and not the sim. It has to do with releasing pressure from the stick, taking my hand off of it essentially, which is causing this problem.

So you're not :joystick: enough :). Great find! Cover those pesky LED's...

Yup, put a piece of tape over the photosite, and end of story.

BBQ, I thought my G940 was bust too but if I switch off FFB it works fine, no drop.

Plus it works as expected in all other sims including DCS modules.
