Which connector type is commonly used with this servo?

Many hobbyists use a standard Tamiya or equivalent connector on NiCd packs for reliable fit, but check your receiver and power setup before wiring.

Can I install this in a small radio yacht?

Yes, the compact L46 x W25 x H46mm size and 83g weight make the S5801 suitable for many small to mid-size yachts, provided you have space for a 42mm drum.

Any tips for prolonging the servo life?

Regularly flush with fresh water after salt exposure, lubricate moving parts lightly if needed, and avoid overloading the drum to prevent gear wear.
