Product description

The PBR-12X is ideal for use in any model where space is limited, but where a large number of channels is required. The square arrangement of the servo sockets allows the PBR-12X to fit even in very narrow fuselages, such as those of, F5J- and F3B-gliders.

The integral electronic switch is operated using our MicroSwitch. If there is no space for this, the PBR-12X can be activated simply by plugging in or disconnecting the battery, as it stores the last switched state.
The unit features an integral high-current input with a compact MR30 connector in order to cope reliably with the current drain of twelve servos. An MR30 to MPX adapter is included in the set. 

Any receiver with a bus output can be used as the receiving component. The unit automatically detects the bus system to which it is connected, which means that no set-up work is required apart from setting the fail-safe positions. Two receivers can be connected to form the basis for a redundant receiving system. If the PBR-12X detects lost data packets from the first receiver, they are replaced with the data from the second receiver; there is no loss of data.
