I find that normally modellers fall into one of two camps.
1) The super tidy, practical to maintain internals, with a gloss varnished, glue stained monster on the outside..
2) The beautiful, museum standard model, with detail to die for, while the electrics have been bundled up with insulating tape, and thrown in from a great distance..
I generalize, just a bit! However, the majority of models seem to fall into one or either camp. It is a referendum majority though!
I think we all improve with experience, given time and the right guidance. My first four or five models suffered from breakdowns, cooked Bobs Boards ( yes, that long ago!!), grubby connections for the electrics, fittings dropping off at every opportunity, and so on..
Then things started to improve, now, with proper design and maintenance ( keeping your batteries topped up being the main thing.) I can charge up, plug in, test the motor, and so far my big SS Ohio tanker has worked every time, without fail. Don't ask me about my U-Boat though!!
