hi there
yes I have four of the 'older version' of these
so, what I will say, they are as good as - if not better - than what there is on the market at the moment. I have fitted them in paddle tug 'Forceful' 'HMS Norfolk' and one to be fitted in my present build which I am busy doing - and I am very happy with them. It's a case of what suits you. If you put them in , I personally think you will be very pleased with them - just remember to follow the instructions
I only wish he did the kit build version again.
As you look at the picture of the internals of HMS Norfolk, you will see - on the right hand side a little box with red labels on it. This is the old mixer unit.
