What type of power source is recommended for best results?

Will this servo work in salt-laden conditions?

The S5801 is water resistant and copes with damp conditions, but it is sensible to rinse and dry after exposure to salt to prevent corrosion over time.

What should I check before fitting to my yacht?

Confirm drum diameter and available space, check radio travel settings for 2 to 6 revolutions, and test endpoints on the bench before installing to avoid overdriving the drum.
