Simple mechanical DIY "trim" for helos

[SirFlounder]

Heya everyone.

 

Flying helos with simulated "trim" is something I have never got used to, It just feels wrong. I prefer flying with dead-stick (like R44 with hydraulics) if no options.

To solve this, I created a test solution to my old rig below with some 3d printing, 4 steel bars and some neodymium magnets:

Long story short, amount of magnets define the resistance/clutch while lubricated steel bars slide on top of each other. Having two "dampers" pointing to corners of the pedestal reduces the uneven resistance, which is the common problem with e.g. Virpil and VKB bases/clutches. After ~1 month testing, works like a charm.

If You want to replace the constant resistance with AFCS  (like in Sikorsky helos), replace the magnets with 12v electromagnets (take power from one USB) and create one switch to Your cyclic that cuts the circuit. Tadaa, button trim. This is what I am building to my main rig currently.

 

Really odd first post

I hope this gives ideas to others. Fly safe.
