@Vaas:
I am currently working on a square rigger (3 masts, 11 square sails, spanker, staysail, 2 x jibs) - I will be starting with three channels (rudder and two winches, one winch is for the foremast and the second for combined main & mizzen)
I am following examples from elsewhere, it seems this setup works for others, hoping it works for me.
With this arrangement it is possible to also include jib control with the foremast winch and spanker control with the aft winch - I am not going to include this for the moment.... I am getting close to a test sail, so will know before long...
There is a good range of budget 2.4 radios at
