It seems that the vast majority of 'Hornby's best ever models' are kettles - and I've nothing against that at all - there are some wonderful models.
I feel more mention should be made to some of the fantastic 'Modern Image' locomotives they make / have made as well.
Opening main line of OP #1: "Which of Hornby's RTR 00 models is best?"
Here's a vote for my Class 50, D421 - what an absolutely incredible model - Hoover in real life, super-smooth rocket as a model ... REALLY!!
It's always been so smooth and quiet, I hadn't realised a little more attention had been required.
One of those pesky buffer ladders was annoying me - wrong angle and a bit wobbly ... fixed now.
I decided a little clean and 'general lube all over' including the motor and shafts was required ...
What was a super smooth, not totally silent, fast-ish locomotive has become near-silent, smoother again and ... WOW ... it must run nearly as fast as my Super Detail HST - which is VERY fast ... if I really push it, which isn't necessary, and is frankly a tad dangerous!!
What a superb model - here's to the Hornby Hoovers!!
Yes, I love the opening doors and rotating fan as well ... I know many have misgivings, but each to his / her own.
