tail rotor drive system.
I am old school, keep it simple, keep it light and if it aint broke don't fix it
unless the fix improves it.
My questions are comparing to the 3 belt system:

1- has the current drive shaft and 2 gearboxes made the helicopter safer?
2- is the drive shaft and gearboxes more prone to mechanical issues?
3- Is the drive shaft & gearboxes lighter than the 3 belt system?
4- has the drive shaft and gearboxes made the helicopter cheaper?

- what issues have there been with the 3 belt system?

Does anyone know what happened with an emergency landing apparently due to the tail rotor belts slipping , a dusty environment and RW's pilot Darren as the pilot?
