Hi Netleyned,
We have several model yachts that are dual control, radio or vane steering and have the radio system, including rudder and sailwinch servos mounted in the main deck hatch with all the lines running above deck. We sail with the Vintage Model Yacht Group in Sidney Park in Cleethorpes on the last Sunday morning each month. We should be at the next meeting on 26th Sept from about 10:00 - 12:00 am. We will bring along a 36R that is set up that way and you are welcome to come along and have a look and if you wish, take photos of the installation.
