Corona DS-561WP BB 10KG Metal Gear Waterproof Digital Servo For RC Models
A part of the review has been auto-translated.
very nice servo's ,they work very good in my boats.
A surprisingly quiet and strong servo. Resolution is typical of Corona digitals with a defined number of steps in the sweep, but for my application as a rudder servo in a large 1.2m long range FPV boat it will work fine. The horns are excellent, being very sturdy and fully up to the torque demands of the 10kg rating. I see no visible seal around the output shaft but the cable entry looks reasonably waterproof. I doubt it would survive submerging for long, and salt water may shorten its life, but I plan to mount it in a way to avoid getting too wet in normal use, as you can't have too much protection. For the price and power it's really a good value servo.
happy with product
As described and expected.
