Cheers mate, yeah I know what you mean about thread spools they almost look like them already... but ultimately the task is to follow the reference as close as possible so I can't take those kinds of artistic liberties.

Just sorted the rotor blades out... to me they look a bit too long now but when I look back at my previous renders they did look short before. Ho hum. :/

Worked a tiny bit on the wheels but not happy with them so I'll play a bit further with them when I've placed the new support beam. I'll do another render later when I'm officially 'done'.
