Hi Walmis,
First of all wanted to say, you've created something to be proud of. This project has lifted the FFB sim world to next level. I have a bit of experience in aviation and sims and it always has been a huge bug bear that cyclic/stick FFB has been the underdog in sim world. Particularly force trim release (and set) option for helicopters. That was actually the reason to start my journey to produce something myself.
Helicopters are relatively easy though; IRL force trim is artifical (hydraulic control operated helicopters); simple clock spring with a clutch to engage/disengage the spring and a trim motor reposition the stick/pedals/collective. No aerodynamic or g-force feedback in controls
I just skimmed through the DIY channel and read some of your documentation. I can see your motors are tightly embedded with the software/drivers and it would be difficult to separate in current design and was kind of expecting this would be difficult but was hoping otherwise. It currently is a well balanced and integrated system.
Next question :D:
What would be the possibility to cascade 2 motors on 1 channel. I see there is a RS-485 connection between the controller and driver board. Any thoughts the driver could drive 2 motors (2 addresses?), using the feedback of 1 motor, i.e. master/slave setup? Feedback/dampening feel would of course needed to be looked at as it is doubled etc
I realize these are not the kind of questions that can be solved over night, but as stated, very keen to see if somehow it would be possible to relatively easy boost the torque. I am just trying to brainstorm here.
You are right that the chonky boys produce quite a bit of torque, but looking at real life, 20nm is only the start!
Sorry, don't want to come across to slag you off, au contrair, but if I look at real life forces (I have done my testing) helicopters require quite a bit more to move through the force trim with 0.6m extension bar. That's why I am so keen to ask these questions.
