Suchacz Posted May 6, 2013 Share Posted May 6, 2013 Isn't the current force trim sound too quiet? For me it's hardly audible. IMHO that click-clack sound should be louder... :huh: Per aspera ad astra!

heloguy Posted May 6, 2013 Share Posted May 6, 2013 It shouldn't be as loud as the Shark's. I'm pretty sure the UH-1 force trim is about the same as that in a B206, which I've flown, and you couldn't even hear it. From what I understand, the force trim system being so loud in the Shark is one of its unique attributes. i9 12900k @ 4.9ghz, 32gb RAM Nvidia RTX 3090 Windows 11 x64 Pimax Crystal VP Force Rhino w/RS F16GRH, Virpil TCS Rotor Plus AH-64 Collective, BRD F1 Pedals, WH Throttle, FSSB R3 w/WH Grip, PointCTRL v2 Link to comment Share on other sites More sharing options...
Suchacz Posted May 6, 2013 Author Share Posted May 6, 2013 Ok, thx. It was only my notion based on flying BS and watching Mi-8 videos, where this sound is nearly as loud as a gunshot :D But I didn't find any video with this sound in Huey. Per aspera ad astra!

manne Posted May 6, 2013 Share Posted May 6, 2013 Regarding Force Trim, what does it do? I don't mean the trim button, but the actual force trim switch which can be set to on/off? Does it enable/disable the actual trim functionality? Or is it something else? Link to comment Share on other sites More sharing options...
Suchacz Posted May 6, 2013 Author Share Posted May 6, 2013 Does it enable/disable the actual trim functionality? Exactly. It is disabling that system, those electromagnets or whatever is there :smilewink: IMHO this is not far from the real thing Per aspera ad astra!

manne Posted May 6, 2013 Share Posted May 6, 2013 Ok. And why would a real pilot use it? In emergency situations or to "reset" the trim? Like, why not just simply don't trim the aircraft in the first place while leaving the force trim on? Or is the activation of the system some kind of trade off...? ah well, it doesnt really matter, I understand the functionality now, just curious :) Link to comment Share on other sites More sharing options...
Suchacz Posted May 6, 2013 Author Share Posted May 6, 2013 IMHO it depends on personal preferences. Somebody likes to fly with the trim, somebody don't... Per aspera ad astra!

Robert1983NL Posted May 6, 2013 Share Posted May 6, 2013 Haha, there's no way you could hear a button's click in a helicopter. It surprises me people say you can apparantly hear it in the Ka-50. Russian old fashioned technology I guess. Force trim is used to trim out the forces that are working on the cyclic. Pressing and releasing the force trim holds the cyclic in the current position, so you don't have to push or pull the cyclic anymore. If you don't use the force trim, you're gonna get a sore wrist after not too long :) Link to comment Share on other sites More sharing options...
Suchacz Posted May 6, 2013 Author Share Posted May 6, 2013 Oh c'mon, don't play smarta§§. Of course I know very well what force trim is. I was talking about a loudness of this sound in Huey, because I know from my personal experience that the trim-mechanism sound in Mi-8 is pretty loud and well noticable in all that cabin noise from the engines and rotor.

Robert1983NL Posted May 6, 2013 Share Posted May 6, 2013 I'm not playing a smarta$$. Someone asked the question, I answered it. :) I've got 12 hours on the Huey, I can't remember hearing a clicking noise from pressing the force trim. Link to comment Share on other sites More sharing options...
AlphaOneSix Posted May 6, 2013 Share Posted May 6, 2013 Sorry, my misunderstanding. Russian helicopters have a relay that controls the force trim. Relays on Russian helicopters are...well..archaic is not the right word...more like...heavy duty. Maybe they were designed to be EMP-proof, who knows. At any rate, they are very loud when they energize/deenergize. And the relay for the force trim, at least on Mi-8/17 series and apparently the Ka-50 as well, is located in the cockpit area. It may stand to reason that people who are not familiar with actual helicopters may think that what happens in one just transfers to another. At least that's my assumption.

Focha Posted May 6, 2013 Share Posted May 6, 2013 In AS365, with engines running you can barely hear it. Although if you are paying attention to it, you can identify the sound. After engines shutdown or before engine start you can hear it perfectly fine "click-clack". :D ASUS N552VX | i7-6700HQ @ 2.59GHz | 16 GB DDR3 | NVIDIA GF GTX 950M 4 Gb | 250 Gb SSD | 1 Tb HD SATA II Backup | TIR4 | Microsoft S.
