Here's mine, still very much under construction, but now operational.
She's approx 1/24th scale, and has a 12v 3700a/h battery pack, 12v 385 motor, mini servo for the rudder and an ACTion Condor esc, and Planet5 2.4gHz radio.
The "load of hay bales" is in fact a block of foam, covered in a section of a bin bag liner, and roped down for sailing.
