You sort of have to watch these guys, because sometimes they get overstocks and sell things at really good prices.
Yeah, and they charge 75$ for shipping alone (to where I am). No good prices for me there. I’d rather make my own controls, 3D printing is capable of producing parts with tight tolerances, the buttons are most definitely doable, though a bit fiddly to design.
The people at OpenHornet state that hats in the Hornet, at least, have a tactile click. If that’s not the case, then the “joystick as hat” solution from Simchair would probably work best. I could add 3D-printed guides, to prevent diagonal movement and constrain the travel. An analog solution has another advantage: it uses up two analog pins on an Arduino, versus four for a genuine hat. Granted, it there are less analog pins overall than digital ones, but this allows you to cram more digital buttons in.
