Reviews (25)
Includes 25 reviews aggregated from around the web.
There are few reviews for this servo on the web. A German forum member ran one for 30 minutes carrying a 500 g hammer and saw no issues, and a video tester says both the DS3218 and DS3225 did well in testing and can be recommended. The line is described as hugely popular with scale crawler builders because of price and waterproofing.
