HI Sergey,
I meant multi boxes not powerboxes, the reason being that the door servos are facing each other and thus one of the pair always needs to be reversed, so a y lead cannot be used
OK, in these case you can use programmable servos and just reverse some of them, ore use Futaba MSA-10 SX Synchronizer, it’s can synchronize 2 servos for each site, totally 4
