Notes
Requires a m3x10mm screw to attach the servo horn to the output shaft. Use of a shorter screw can cause failure and will void your warranty. Circuit board is conformal coated for vibration and element protection.

Reviews (5)
Includes 5 reviews aggregated from around the web.
There are few reviews for this servo on the web. Nitro racers recommend it as a good balance of speed and torque that is strong, fast and has an aluminum case, and one says it is a no-brainer for some builds. One owner burned out the motor through their own mistake.
