The model also has 2 props (1:6 gearing). All motors are como / pile gearing.
To change jib from port tack to starboard tack:
Move sail gimble on transmitter half way to left. This activates "D" limit switch (starboard motor) which releases starboard jib sheet. Allow a couple of seconds (this is to not put stain between the port and starboard motors), then move the gimble all the way left, this will then activate limit switch "B" (port motor), which will pull port sheet jib in and around schrouds/masts/other jibs/staysails. Limit switch #2 will stop travel of starboard jib sheet and limit switch #4 will stop travel of port jib sheet. The position of where limit switches 1 & 2 and 3 & 4 is determined by how much the sail is required to be hauled in or let out. The reverse for port tack and limit swich "C" (port motor) is first activated and limit switch "A" is activated. Limit switches 3 and 1 will stop the travel on this tack. If a "run" is required, just move gimple to half-way, left or right, to activate limit switches "C" or "D" depending on which tack you are on. To simplify things, if you want sails on the port side of the boat (starboard tack), move gimble to left, and vice-versa forsails on starboard side (port tack).
