Hi Haddock,
Like Francis, as an Aircraft Modeller, I too could say the blades look a tad heavy, but remember it is 'Your' model and you portray it as best you can in such a small scale.
Your skills at 1/350 could knock our efforts at 1/72, 1/48, 1/32 into a cocked hat...!
An excellent model Sir,
Now, what's next on the 'Haddock Slipway'.
Cheers,
Bigkev
