• Description



The power package.
Programmable S.BUS - Brushless - High Voltage Servo of the 20 mm size, with 210 Ncm the second strongest servo of the Futaba BLS series. Direct operation with 2S LiPo batteries.
With central aluminium housing part for cooling the servomotor. Powerful all-metal gear for converting the moment of force.

Ideal power servo for large model aircraft, TOC machines etc., wherever pure power is required. The gearbox has double ball bearings and is coupled via an indirect drive system to the special potentiometer with 6-fold slider.
A water-protected housing design allows use even under the toughest conditions.
HV version of the NV servo BLS155, successor of the BLS156HV and BLS175HV-SB servo, now with S.BUS2 technology.

Futaba Servos have enjoyed great popularity for years due to their high quality and many innovative solutions. The servo line includes servos for almost every application in model making. Many servos are designed without internal wiring. Futaba servo gearboxes are characterized by unsurpassed precision. In some servos, bell-shaped armature motors are used for powerful, fast and powerful servos. Digital servos with microprocessor technology offer higher holding power, shorter response times and 4 times the pulse rate compared to conventional servos. BLS/Brushless motor technology: no brush wear, 30% shorter reaction time, more resistant to vibration and shock, higher efficiency and higher resolution, same power consumption. S-BUS technology with following advantages: fewer cables, lower weight, lighter weight, easier cable routing, easy parallel connection of servos. S. BUS servos can also be operated at the normal PWM receiver output. HV servos can be operated directly with 2S Lithium batteries in the voltage range of 6... 7.4 volts. Due to the higher voltage, the power consumption is lower with the same servo power.
