Waterproofing The CYS S2220 Servo


My Losi Nightcrawler Project, dubbed the Crawling Dragon, was in full swing, and I needed a waterproof servo! CYS's servos are all waterproof, but I decided to go a step further!

CYS was an obvious choice for me when looking for a powerful servo for the Losi NightCrawler build. With almost 250oz of power at 7.4Volts (using a BEC), the CYS-S2220 is a true beast. Titanium gears are used for reliability. The servo in its stock form is already waterproof, which is a great feature to have on crawlers. However, I wanted to double down on the waterproof job to make sure if my baby took a deep dive, it would come out unscathed! Check out my video below to see how I did it!
