Great servo. Good power and speed. Only complaint it’s noisy compared to reefs. I have never seen a quiet savox servo though lol. Would recommend it.
These are the best servos I’ve ever owned. Incredibly strong and fast. Just put them on my Kyosho MP10 TK12. Super smooth and quiet as well. Worth every penny.
I always have good luck with every savox servo I buy and this one by far is the best of them all
Absolute beast of a servo. Super well made, looks awesome, tons of power, long wires so you can run them how you like. It's worth it. I love it.
Works great in my xmaxx once I set the end points.
Reviewers broadly rate this Savox high-voltage brushless servo highly for strength, speed and torque, with many running it in large trucks, buggies and crawlers. Several praise its build quality and long-term reliability, including one reviewer who reports years of trouble-free use. Noise is the most frequent point of disagreement: some describe it as quiet, while others call it loud or not the quietest option. Reviewers also note fitment issues, including needing to trim a bracket on an X-Maxx and a fitting problem with a chassis adapter on a Mini Maxx. One reviewer reported an O-ring breaking on arrival, and another reported a unit failing out of the box, which was replaced. Several reviews mention the servo running at 6V and 8.4V. Ratings are mostly 5/5, with two 4/5 and one 3/5.
