Hi William
I have had a quick eyeball of this model on Ebay and it looks a good model – price is a bit steep I think – but, everything is expensive these days.
To me the rudder has been 'flipped' round and that makes it look a bit close and in the wrong place and with regard to the prop shaft angles, they seem pretty close to the original on the real 'I am' boats. I think on the life sized ones I think they are around 13 degrees which look about right on this model.
The original boat also had 3 shafts and this one looks as though she is only twin, and I do think it wouldn't be too difficult if you wanted to add an extra shaft and reposition new rudders – 3 off. It does look a very well made model though.
Just my thoughts:
Aye
John
