Kristiansand is a beautiful place, i visited a couple of times on business several years ago.
Good luck with your heli, I'd advise finding a good instructor. I've flown fixed wing for years but have pretty much decided that heli's are impossible to fly. Anyone who says they can fly them is lying and the sightings of RC helis flying are either mass hallucination or trickery with mirrors.
ok.. possibly a little tongue in cheek with some of this, but the advice on finding an instructor is real.
As for power supplies. You will need a very high output power supply if you want to use your Powerlab to it's full extent. Converted computer server redundant power supplies are impossible to beat IMHO. Not only do they offer more power than any other option but they are a fraction of the price of hobby power supplies.
