For the servos we found for the sail servo and 10Kg servo was enough power to pull in the sails when needed. The rudder servo we used was an Emax ES3054 which is plenty power enough.

Just got home from the maiden voyage and I'm so impressed! You have designed a spectacular boat in the RS850, excellent acceleration and super speed.

This is the upcoming RS850 design. It has some very unique experimental features. A very long keel with a lighter bulb. A twin mast stayless rig. A stern hung rudder. So far test sailing, she is performing very nicely.
