I got rid of the spring and centre detent on my combat pro's and never looked back, I just go by the string (or gauge) to make sure the helicopter is in balance. Although when I build proper toque pedals they will just have a damper to provide slight resistance to movement just as it should be.

Cheers Frag.

Dear Molevitch,
fantastic work! I've read everything here twice! One question has remained: Will the trimmer also work momentarily? Meaning: recenter by a single short push of the trim button?

Greetings,

Viktor

Okey, this is what I have found in the manual:

Quote:
При необходимости летчик может снять усилия с
ручки управления и педалей путем нажатия кнопки
триммеров, расположенной на ручке продольно-по-
перечного управления вертолетом. При нажатии
кнопки происходит растормаживание электромаг-
нитных тормозов ЗМТ-2М, поводки которых связа-
ны со штоками пружинных механизмов, и усилия с
ручки управления и педалей снимаются практиче-
ски мгновенно.
The last sentence basically says that, once the trim button is pushed, the force is "removed" instantly. So I guess, pressing the the trim button and releasing it right away should also instantly give you a new "center spring" position.

Molevitch, does that work with your setup? Maybe you could make a video of that?
Once again - fantastic project! I'm already thinking about something similar.

Hi Viktor,

Thanks for the kind words. I am currently working out how to make a video with 3 or more simultaneous views, including one of the actual stick and collective in use. In fact, I have now worked out how to do that, so will soon be making the actual video.

The trimmer button releases the magnets so the stick goes loose. I have to centre it manually, there is no spring to bring it back to centre. I use the red diamond instrument indicator to check for true centre and keep it on most of the time.

So without pressing the trimmer the cyclic is in a fixed position, held by the force of the springs in the force gradients. I can make miniscule adjustments by pushing the stick against the springs resistance. But I can press the trim button and keep it pressed and simply move the stick all over as I please. Or I can do a momentary press to trim and release.

This means that I can actually set the cyclic trim, set the collective brake, and hover, hands free. I can make a cruise turn, hands free. I can have fine control in the hover, once trimmed and move back, forwards, sideways, turn etc, all with hardly moving from the hover spot. Great for slingloading, embarking, disembarking troops etc. But also when set up as a gunship, I can hover and snipe! I am trying to see if I can land hands free! Only as a proof of concept of course.

So yes, in answer to your question, it does do what it says in the manual.

Now, I must get that video made! Oh, please give me some rep!

Thanks Hannibal,

I too cannot wait for the Mi-24, don't mind which version really. I do hope that the multicrew system really comes together this year!

Though it is not completed yet, thanks to you, I was able to produce collectives so far.
Thank you very much.

WOW, that's amazing! Great looking result. How are you damping the collective axis?

Will you do the cyclic as well?

I look forward to seeing the next stage.
