SPIN pro 300 Opto, Electronic Speed Controller (850300)

The SPIN pro 300 Opto, Electronic Speed Controller (850300) controllers are successors of the former brushless series SPIN controller family. The new line with the attribute PRO offers in comparison with the predecessors increased adjustment possibilities like automatic motor timing, directly in volts practicable shut-off voltage adjustments, tuning of start-up properties for different motor types as well as new possibilities of mode activation for setting up autorotation of helicopters.

OPTO controllers have galvanically separated input (signal from receiver) from power accumulators, therefore it's necessary to use independent supply for receiver and servos (4-5 NiXX or 2-3 LiXX with linear voltage regulator, such as MAX BEC).



SPIN OPTO controllers are provided with two JR connectors. Connector on longer three-line cable with black ending is to be linked to the receiver. Connector on shorter three-line cable with red ending is intended for communication with JETI BOX; for programming or data reading connect it into slot marked imp. + - on JETI BOX SPIN controllers have extended for telemetry, compatible with DUPLEX.
