Quys, have you noticed some of the innovative new servos Strike models is bringing in? They have a 4+ turn sail-winch servo that is the size of a standard servo (probably less than 1/2 the size of a Hitec Sail Winch, and more turns) with O-ring water resisting design. pretty close to the price of the much larger Hitec. Sweet!
And, a really tiny microservo with unique mounting possibilities.
Cheers,
