Hi Roger,
Welcome to Paddleducks....
My model of the PT Lingdale is still only about 1/3 built due to moving home down to sunny North Yorkshire.... I do hope to make some more progress with it soon.
I wouldn't consider it to be a beginners model - Though that really depends on your basic skills! The paddlewheels are a work of art, but you do need to have some metalworking experience to assemble them as there is a fair amount of fine soldering involved. And as it isn't a full kit, you need to make various bits and pieces yourself from the drawings that are supplied with the hull....
It's certainly possible to make a steam powered model, but I'll be using electric as my preferred method of powering it.
Regards
Eddy
