Hi john,
There have been a number of articles published on this topic in recent years. Generally they relate more to scale sail but the techniques are equally applicable to pond yachts. Usual discussions revolve around servos – winch or arm, power requirements and, I think of interest to you the sheet runs, the use of internal tubing and play off of linear movement over power and perhaps the use of microswitching as stops or for reversing.
The use of pulleys and achieving large radius bends is generally wise with some means to take up slack (elastic or spring) and stop the lines from fouling internally if rapidly released.
There are also a couple of good cheap books relating to RC sail which include chapters on these topics but not from MB publisher as far as I am aware…..
My own experience leads me to not try and control too much – ie foresails not always necessary, especially jib and foesail seperately although many do it successfully and on a straight forward rig is not too complicated or requiring many RC channels. I keep hearing that a well set up boat shouldn’t need too much intervention – but it is fun to try and improve your capacity to control even if the boat could do better on its own!
Good luck – I have a car boot pond yacht as one of my ‘unfloated’ projects so will be thinking further on this myself.
Regards,
Cap’n Jim.
