Have gone for it with the radio control- - employing a Robbe F14 plus an extra 8 channel module with decoder. So far extra controls are : each monitor (scratch built using brass pipe & sheet) left & right (using Robbe pulley set to give me 270 degrees travel), two Irvine water pumps, (real car) hooter, winch (using gearbox from Maplins) and movement for jib and search light.
I sail at Brentwood in Essex - where you can still run IC boats.
