Bit more info from Haya ltd today. Latest update from Andrew on the proposed new system. Schematic of functions. Also asked about customisation, seems the answer for that is a no as the system stands at present

as it’s a self contained system with a single sound set. So no computer connection or dip switch to customise settings.
However Andrew has said this is only a beta test unit and he will be talking directly to the manufacturer about possibly upgrading the battle system and making it customisable for weight classes and adding a correct sound set for his next tank. Will keep you informed as information reaches us.
