The PowerBox Royal Spektrum 12K represents the newest generation of a power control unit with integrated Spektrum 12 channel DSM2 receiver technology. With this newly developed product consumers will have a powerful Dual-Power-Control system for their valuable model airplane along with the security of Spektrum's DSM 2.4GHz technology. This allows not only the extra safety advantage of coupling two on board flight battery-packs, but the most robust RF link in the industry.

The PowerBox Royal Spektrum 12K is housed in an elegant, high-quality injection moulded case. The capacity of the linear regulated voltage for the servos has been substantially increased in order to cope with the latest current-hungry servos. The voltage for the servos can also be selected by the pilot himself: either 5.9 Volts or - if the electronic design of the servos permits - 7.0 Volts. The 7.0 Volt supply also features linear stabilization to ensure that the servos run perfectly synchronously.

The unit's comprehensive adjustment facilities for three control channels are particularly important with F3A-X class model aircraft, as they often feature multiple servos coupled to each control surface. The ultra-precise electronic servo adjustment available with the PowerBox Royal Spektrum 12K enables them to exploit their full potential power and transit speed; at the same time they also draw considerably less current than servos adjusted by mechanical means.

Flight-relevant data can also be read out on the backlit LCD screen after the model has landed.
