JX Servo CLS-5830HV Standard Digital Servo, High-Speed, Mega-Torque,Waterproof

Awsome servos!!I did have issues with 6v but once I installed it on my Kraton using 8.2v it cam alive and no jittering.I have Proline Rock rage tires which are huge and this servo handles them as if it didn't have tires on.I really like this servo,especially since it's water proof.I highly recommend this servo!

Worked great for a week. Not in the rock. Servo gave up after about a hour in the rocks. Stripped out a gear or some thing on my scx10 with 2.2 venom switch backs.

No longer works! Was lightning quick and torquey for a few runs! Much needed upgrade for tracks with 180 turns. Update: after 4 runs with the servo, it has failed, won't turn, constantly changes the trim settings on its own. Has become unusable.

So far so good. Easy to mount. Will see how long it lasts with my Jumbo Mudder tires !!
