This is a sailing Yawl base on the yacht Argyll. The hull is 41" long with a full keel. There is a single drum winch servo that controls all the sails. in the static display mode she has 2 head sails as per the real boat. When rigged for radio control sailing the 2 head sails are replaced for a single head sail. The radio control equipment is an older Spektrum D6 with a Spektrum receiver. The hull is an epoxy construction and was given to me by a club member an that was down-sizing. The sailing rig was all made by myself. (8/10)
