JR - JRPSNXB8921 - NXB8921 Brushless High Torque XBus Servo
Ask any competition IMAC flyer or serious giant scale 3D enthusiast what their servo of choice is, and youll undoubtedly hear â€œJR of courseâ€. This isnt by accident- JR servos like the legendary 8411, 8711, 8911, and recently introduced NX Series â€œSmart Servos 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 servos that are destined to be the next legendary number in giant scale performance servos, the new NXB8921 and NXB8925 Brushless Smart Servos.
Both the new NXB8921 and NXB8925 feature highly efficient and powerful brushless motors, and updated firmware for optimized performance and efficiency, as well as a new robust all CNC Machined aluminum cases, and of course all metal gear trains for the ultimate in durability.
Add to all this a plethora of programmability to customize and fine tune each individual servo to its specific location on the model via JRs innovative XBus DMSS Serial Bus system, and well, the new NXB8921 and NXB8925 might just be JRs smartest Smart Servos of all…
Not using XBus- fear not. The new NXB8921 and NXB8925 also features JRs unique automatic output detection, so it can be used in standard configuration with either conventional (PWM) or XBus installations for ease and flexibility with virtually any brand of equipment.
If youre looking to take the performance of your model to unprecedented heights, take a look at the new NXB8921 and NXB8925 servos from JR and feel the difference these new JR NX Smart Servos can provide.

KST X20-2208 High Voltage Brushless Servo
The X20-2208 is a high voltage, high torque, high end burshless cyclic servo from KST.
The all new X20 servos (X20-2208, X20-1035) are mainly designed for competition level 3D helicopters (550-800 size) and will provide ultimate performance and best value without any doubt.
Equipped with an all new CNC aluminum case, the X20 servos are not only much more visually stunning and elegant than ever before, but also brutally durable and stable. The grooves on the case provide better cooling in the extreme conditions.
The utilization of the high-end Namiki brushless motor ensures the ultimate in performance with lightning fast speed and undefeatable torque. The X20-1035 (for tail) can deliver 0.07sec/60° and 25Kg.cm when operated under 8.4V, meanwhile the X20-2208 (for cyclic) perform as 0.03sec/60° and 12.00Kg.cm. Besides the smooth performing and low-noise operation guarantee excellent control experience.
Unlike any other servo, the X20 generates no counter EMF in any working condition thanks to the all-new design IC board. From now, your flybarless system and receiver will not be interfered anymore.
Every X20 servo comes with a creative metal servo arm. This servo arm allows for continuous fine adjustments of the angle just by loosing one screw. And it can protect the servo gears during a crash.
The X20 series are the best servos KST ever made. With them you will experience the ultimate in every respect.
