The #3703 is a mechanically proportional sail control unit that simultaneously adjusts the main and jib sails. It sets your sails in relation to the control stick on your transmitter. This eliminates the old “bumping” method of setting sails. Sold in kit form, this sail control unit is recommended for sailboats over 36" long, with sail area over 700 sq. in. Batteries not included.
