Jayko, excellent model, I voted for it. Great to see that we have another Technic builder here as well.
Is the turntable on the motor a part of the mechanism, or just as an aesthetic component?
The turn table is actually ran directly from the motor, it then turns a 8 tooth gear which is attached to a 40 tooth gear, which finally turns another 8 tooth gear. Its a 7:1 ratio multiplied by a 5:1 ratio.
@CC I would have to say the hardest part was the underside redesign. I was using water bottles as flotation, until I learned that they were prohibited by the rules... So I had to cram and find a way to fit those boats on. Another problem was the strength of the round pannels, they were really flimsy. I added bracing, and ended out with a fairly sturdy model!
