Remove the spring and don't use the force trim.

Kinda works, more trees... zHS9nSVjix0

Thanks for clarifying.

Please elaborate :huh:

That's what I want to know as well... Matt says Kamov signed off the sim to train operators so I want to believe the systems are accurate as hell but who knows.

According to Chizh the Hud in the real video is supposed to be an early variant that was refused. The default hud in DCS is a later more modern variant. I use a mod to changes the scales and bird mark too look more like in that video: https://forums.eagle.ru/showpost.php?p=3109972&postcount=46 The upsets in attitude in there in the real video, it's just comes with the system. The kamov is one of the few actual mil sim modules that ED managed to get to us consumers. If a critical system like autopilot behaviour during trimming wasn't accurate it wouldn't have been good enough for pilot training. With practice it's possible to be minimised.

Thanks for posting that, inspired me to do a similar flight right away. :D qckM1S9xOEw

Yeah its the trim button, it makes a click both when you first depress it and then when you release it, there is a tiny sound difference between them. I believe first click in the video is from pressing trim reset button though. Like 90% of the video I'm holding down the trim button to get FD controls behaviour. Normal autopilot is on, no route mode.

Good thing it's fun helicopter to practice in! Try out Holbeach's mountain slalom mission in this thread: https://forums.eagle.ru/showthread.php?t=167089 It's a nice course for practice in any helicopter module with hard turns, elevation changes and low power lines to squeeze under as fast as you can. HYXwfkdSfRQ It totally depends on the helicopters designer but in general in light and early made helicopters you wont find force trim systems and many pilots dislike them in these air frames if they are installed due to interfering with small balancing movements on the cyclic. Bigger and more modern ones do mostly fly with a force trim system on all the time with some type of SAS/autopilot. With a force gradient on the controls they can be designed with a lot more advanced autopilot systems like on the ka-50 that makes hands off flying possible. There are some sim equipment manufacturers do real trim in dedicated heli sim cyclics like this but I have no idea where you can buy or how much it would cost... HjuD-_gSP4A

Crick trimming only works smoothly when re-trimming from a relatively small speed difference. You can't be trimmed for a hover -> push stick forward to accelerate to 200 kph, then trim. The helicopters nose will violently pitch down when you depress the trim button as the autopilot was using 20% back stick to try to get you back to previously trimmed speed (hover) but when you depressed the button that 20% back stick force goes away instantly = nose drops. What you want to do is either hold down the trim button while accelerating/decelerating to whatever speed you want then release it or click the trim button every 10-30 kph you gain/loose to reprogram the autopilot to new speed before it starts using more than a few % of it's authority.

Same issue as reported in these threads: https://forums.eagle.ru/showthread.php?t=168228 https://forums.eagle.ru/showthread.php?t=172774

I use a FFB stick with Simffb with friction & damping effects separated from trim spring forces so it doesn't go limp when depressing trim (what I assume real stick does as well) and I use both methods all the time. Click trimming when flying stable with minor stick deflection and depressing button in transient conditions to prevent over swinging. I don't have that controls indicator on in this video but you can hear the trim button pretty well being depressed mostly. HYXwfkdSfRQ
