  • 【Excellent Quality Workmanship】:The 7KG Micro Digital Servo made with excellent Plastic Shell material (lightweight and fast heat dissipation) and high-precision Full Metal Gear (more durable and prevent tooth sweeping) with Hard Anodizing, combined with Dual Ball Bearings, has a longer service life.
  • 【High Performance Digital Standard】:The 7KG Mini Digital Servo with Extra Large Torque can achieve Low Noise, Good Stability, Small Vibration, Smooth Operation, Excellent Linearity, Precision Control, Fast Response.
  • 【Widely Use 】:The Mini Digital Servo is suitable for remote control vehicles such as Crawlers, Buggy, RC Car, Boat,RC Aircraft,RC Helicopters, On-Road,Off-Road,RC Drones,Toys,etc.Especially this servo is most suitable for micro control fields such as aircraft models, drones, toys, intelligent switches, etc.
  • 【Electronic Protection】:The 7KG Servo will undergo current reduction and power outage treatment when the locked rotor time and current exceed the preset values, preventing blockage and burning. A solid hardware foundation combined with more advanced software allows the servo to provide high torque output while significantly reducing the probability of damage to the servo under high loads.
  • 【Note】:In the frequency range of 500~2500us, the maximum controllable angle of the servo can be accurately achieved at 180 degrees, and the servo can achieve a control angle of 90 degrees under the control of a transmitter.

This NEEBRC 7KG servo is definitely a step (or two) up from the usual budget servos I've been using. In a package the same size as my SG90s, this little unit puts out roughly 5x the torque, has zero detectable backlash, and an apparent dead zone of no more than 0.4 degrees. The metal gearing really shows in its reliable strength and positioning accuracy, and while it is slightly louder than a plastic gearbox, it's negligible - nowhere near objectionable. Speed is not this servo's strong point, but it's no slouch; it takes about a second to swing through a 180 degree arc (which seems to be about half what was advertised, but my measurements were unscientific), though if that's the tradeoff for the power delivered in this small package, I'm all for it. If nothing else, that reduced speed helps to reduce the jerk on connected components. I haven't attempted to max out the torque on this, but it's been easily handling lesser loads with only modest warmth in the gearbox.In the end, this seems to be a very capable and compact servo. It's definitely on the spendy end (~24 USD at the time of this review), when compared to similarly spec'ed products, so I'd recommend some comparative shopping to ensure the value proposition meets your needs.
