Hi Alan,
The Norden is a great kit and offers some chances for creativity as well. The boat, built as per the plans, has a lot more nets etc. which look great. I wanted that Nordic working boat look and it was east to achieve.
The 1060 is a great ESC, I use those a lot in my boats. The main difference, other than the price, is that the 1080 offers a lot more configuration options via a programming card, which is great for rock crawler but not really required for boats.
I run my Norden on a 7.4 volt 2S lipo pack, 1500mAh but I have had to manage the power via the esc as unchecked it almost makes the boat plane. I think a 7.2 or even a 6 volt nimh battery would be more than adequate. This is not a power hungry boat and I can run pretty much all morning on the 1500 mAh pack and still have power left over.
Hope that helps
Carl
