Overview
Power HD Storm S50 Standard Brushless 50kg 8.4V Metal Geared Servo.
Note
Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience brown-outs where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver smoothing the current delivery. However, in some cases, you may need to install an external BEC.

Verified buyerBest servo I've ever owned! I would highly recommend this servo to anyone that is sick & tired of busting cheap servos. Very strong & very quick. Very impressive even running on 6.0v. I have all my servos running on 7.4v now so it is even better. Super quiet being brushless & very smooth not jittery at all.
