Graupner,COMPACT Control 50 OPTO/BRAKE,2885

COMPACT Control 50 OPTO/BRAKE Graupner 2885 A new series of brushless speed controllers. An excellent choice for use with the new GRAUPNER COMPACT motors. However, these controllers are also suitable for use with conventional brushless electric motors such as ULTRA Sensorless, CARBON 70 and EVO one 50 high-performance types. Performance features of COMPACT-CONTROL brushless speed controllers:
Plug & Play prepared for GRAUPNER/JR radio control systems and GRAUPNER COMPACT high-performance motors.
High-capacity BEC system* to power the receiving system. With Auto Cut-Off safety power-off circuit.
Ready-programmed EMF brake (BRAKE) for electric gliders with folding propellers.
Ultra-simple programming for other forms of model such as electric power aircraft and model boats.
Outstanding performance figures. The stated nominal current, printed very clearly on the controller´s label, may safely be exceeded briefly without the system shutting down.
Ultra-responsive start-up and control characteristics; ideal for aerobatic and show-fly moels.
