Serwa Combo NEXSPOR 3x BLS4028S / 1x BLS4012T
3x BLS4021S / 1xBLS4012T - Servo Set for helicopter of the 700 – 800 class
The new Nexspor 40mm brushless servo has been tested and optimized to the limit in countless flights by our team for maximum performance and long life.
The servos are characterized by high speed, positioning accuracy and a lot of power. Pleasant is also the operating noise.
The crunching and crackling is a thing of the past in the stand and under load.
The case of the servo is designed to fit in the most popular helicopters. Example for Goblin helicopter you don´t need any require additional shims.
We tested it at Goblin 570-770, Align T-Rex 550-700, Mikado Logo 550-700, Gaui X5-X7, XLPower Specter 700 and Protos 700-800.
