SAVÖX SV-1257MG+ Servo

Description
The SV-1257MG+ is a fast midi servo which is very well suited for use as a tail servo in helicopters up to 550 class. Of course it can also be used in RC cars. Use as a throttle servo for nitro helicopters is another option. The new + version of the well-known SV-1257MG+ servo differs slightly from its predecessor both visually and technically. A soft start which moves the servo slowly into the start position when switched on and the Sanwa SSR mode characterize the + version.
The technical data of the servo leaves nothing to be desired: 0.07/0.055 sec/60 degrees and 4/4.5 kg*cm at 7.4/8.4 volts
Control frequency up to 333Hz, center pulse 1520us
Like all HV servos from Savöx, the SV-1257MG+ can of course be operated with up to 8.4V!
