LCYCowboy Posted February 5, 2017 Share Posted February 5, 2017 I am lucky enough to have the full Komodo Sim Huey kit, and the cyclic is hydraulic damped free moving without any centre spring. In the Mi-8 options there are several trim options, and I have chosen the non FFB, no centre spring one. My question is, what does the trim button now do. As far as I understand it, in the real helicopter, your move the cyclic (pushing against forces) and pressing the trim button removes those forces so that the stich position stays where it is, but there is no longer a force to push against. On the sim rig, the cyclic moves to a position, but as it has no force feedback, there are no forces acting against it, and removing your hand from the stick, just leaves it there. So what happens when I now press the trim button? I am a bit confused (easily done) :huh: Link to comment Share on other sites More sharing options...
Holton181 Posted February 5, 2017 Share Posted February 5, 2017 If I have understood it correctly, the "no FFB, no centering spring" is for when you have a very well balanced joystick/controler so you can leave it at whatever position you like and it will stay at that position without FFB. It's unfortunately not very well documented, there exist a thread (don't remember where) that shows how some of the developers modified a joystick with weights and friction to achieve this stay-in-place-without-FFB behavior. I believe the default trim optio would be the best for you (press when changing attitude, release when settled, return joystick/controler to center rather fast). I have that for my PFT Lynx.

LCYCowboy Posted February 5, 2017 Author Share Posted February 5, 2017 Cyclic Trim button My cyclic is balanced and stays in place when you let go. It has no centre position. So what is the point of pressing the trim button when the joystick already stays in place? Link to comment Share on other sites More sharing options...
Cibit Posted February 5, 2017 Share Posted February 5, 2017 If you dont need trim then don't use it. The trim in game is designed for generic joysticks with spring centring. Your lucky enough to not have to use it. I went from stiff warthog to 15cm extension and the big spring removed so was like your setup in that regard. It makes for much smoother flying and I never found any difference when changing the settings from trim to no trim and no ffb options i5 8600k@5.2Ghz, Asus Prime A Z370, 32Gb DDR4 3000, GTX1080 SC, Oculus Rift CV1, Modded TM Warthog Modded X52 Collective, Jetseat, W10 Pro 64 [sIGPIC][/sIGPIC] Adding JTAC Guide //My Vid's//229th AHB Link to comment Share on other sites More sharing options...

Just a correction, IRL, you push trim release, move the cyclic (without to push against forces) then release the button. Your stick will stay in position.

LCYCowboy Posted February 5, 2017 Author Share Posted February 5, 2017 Thanks for all the replies. I just couldn't work out why the developers had put in an option for non-ffb no-spring when it doesn't do anything. It makes a noise in the cockpit, so I suppose it is a placebo. I might use that button as the engineer/autopilot reset instead Link to comment Share on other sites More sharing options...
Holton181 Posted February 5, 2017 Share Posted February 5, 2017 I don't fly this bird or the Huey much, and don't use the autopilot yet, but for the KA-50 you need to have the helicopter trimmed before applying autopilot, hence use the button. I assume that's valid for the Mi-8 to?

Weta43 Posted February 6, 2017 Share Posted February 6, 2017 Yes, Trimming does set the desired heading pitch & altitude for the AP channels, not just release the forces on the cyclic. Cheers. Link to comment Share on other sites More sharing options...
AlphaOneSix Posted February 6, 2017 Share Posted February 6, 2017 On the Mi-8? It shouldn't. The pitch and roll channels just try to hold the current pitch and roll attitude. Trim button has no effect on that, or at least it shouldn't. On the Mi-8, the trim button only removes the trim spring force for the cyclic and pedals.
