Up to a certain S/N Eucopter kept the "old" LACU panel where it can be hard to see.
But within the last couple of years they have switched to a new LACU panel where the buttons both have longer physical travel which makes it easier to see - and as Hidden Agenda writes - most of them have lights.
To make it more interesting almost all the buttons have switched places aswell - which makes it quite challenging if you fly one of each...
