that's great to hear! like I said, even if bearings can't happen things like POM (polyoxymethylene) bushing or bearings might be a good choice too. they're a little lower maintenance and a little cheaper i believe, while still providing benefits over just plastic-on-plastic contact. Walterson's is using them on their T-72 for many of the reasons I've already enumerated, apparently.

one other thing - has there ever been any consideration to seeing if y'all could get more appropriate sounds on the electronics used? While the 6.0 electronics (and especially Haya's choice of controller) give great drivability, it always does strike me as silly to hear T-90 or Leo 2 sounds come from the Chieftain (and eventually Centurion), even if the sounds are high quality. as the Haya lineup expands though, maybe you could find a way to package your own set of four sounds? Chieftain/Centurion/some other model/yet another model? Always been curious about that. Seems like it'd be pricey, but at the same time the sounds seem like they're stored generically in some part of the overall board assembly (so I hope), rather than packaged on-die in the controller MCU itself. some part of me has wanted to investigate if there's any way to reflash the memory onboard somehow, for this reason.

regardless, i do appreciate the openness to feedback and the willingness to take on suggestions from the community. i work in AAA gaming for a franchise that is constantly drowned in feedback, much of which we try to act on, but also understand that for those outside the industry (and in this case, I'm the industry outsider) it's far too easy to conjure up wishlist items that just aren't feasible for various engineering reasons. sometimes though, it's just fun to dream
