Ask any competition or 3D Heli pilot what their servo of choice is, and you'll undoubtedly hear "JR of course". This isn't by accident- JR servos like the legendary 2700G and 8900G have provided the perfect blend of brute strength and precision, with unmatched reliability for decades.
In keeping with this tradition, JR has just released their next servo that is destined to be their next legend in helicopter tail servos, the new NXB89G Ultra Speed Brushless Tail Smart ServoTM.
Based on the legendary 8900G, the NXB89G in addition to its highly efficient and powerful brushless motor, features updated firmware, optimized for performance and efficiency, as well as a CNC Machined aluminum heat sink center case for the ultimate in durability. Add to that a plethora of programmability to customize and fine tune each individual servo to its specific location on the model via JR's innovative XBus DMSS Serial Bus system, and well, the NXB89G might just be JR's best tail servo of all.
