Just wanted to share my next project, as well as look for any advice. I was able to acquire an OH-6 cyclic grip, and want to modify it according to some H-60 pictures I've seen in some walkaround websites. Here's the original grip:

What I would like to do is the following:

In all, I see 25 total buttons.

My plan is to make this Warthog compatible, so I already see a problem with the number of buttons. If I can substitute some of the buttons for all eight ways of a POV switch, then I'm good, as the button total will be 17. If not, then I'm stuck with 21 desired, and 19 available, unless I'm mistaken about the max button count available through shift register.

So far, with buttons, I would like to replace the ICS/Radio rocker (I'm sure it's old)with a like switch, but will test it to see if it actually works with a meter. The rest of the buttons, I also plan to replace with what's in the pics. I need to take some measurements to see how big the switch bodies need to be (as well as how big the tail piece needs to be), but I'm definitely open to suggestions on where to find such switches. The biggest hurdles I see are adding the second trigger (mainly due to the modifications required), and adding the rocker switch for force trim release (ringfinger switch on the left side as pictured).

Also, what is the best way to PCB this beast? I do have a Warthog grip with a VKB adapter that I never use, but I'd rather just save that, and get something new and separate.

I'm also aware that just wiring the switches to a BBI-32 or something of the like might be the only option, but I'd like to save the USB port on my computer. It's not out of the question, but if I can make it Warthog (Shift register) pure, that would be ideal.

Thanks for looking, and any suggestions.

POV HAT has 4 physical switches - diagonals are "virtual", created by firmware when two near buttons, eg. N + NE is pressed simultaneously.

Then you have 23 physical connections for buttons in Warthog Shift Register*, plus four "virtual" buttons (diagonals).

For use this four "virtual" buttons you need make a diode net isolating then.

* You need place a Shift Register PCB inside you heli grip.

Thanks Sokol, understood. Sounds like it would be easier just to sacrifice two buttons and keep it at 23.

There should be plenty of room in the top for the PCB, depending on switch size, and PCB size. Do you think going the route of trying to get a grip from Thrustmaster would be easiest to get most of what I need?

It’s actually going on a CLS-E base by Brunner.

Try get parts - HAT's, Shift Register PCB from Thrustmaster - some have success, others no.

Or get an used Warthog, Cougar for use their HAT's - you can 3D print different caps for then, and Shift Register PCB.

Or use ALPS RKJXL 5 way switches as HAT's and 3D print caps - Debolestis (ED forum) have various models in their Shapeways store.

He can furnish the needed Shift Register PCB, as well Rel4y (ED forum).

Yeah, I spoke with Mole over at ED forums through PM, and he recommended the same thing as far as contacting Thrustmaster. I guess it would be cheaper to even go with the used Warthog, since Otto switches are so expensive.

With the ALPS RKJXL 5 Way switches how hard would it be to wire them up so all switches work using shift register? It would be the three total, so 15 buttons between the 3 HATs.
