My Nangee is full of gadgets, it has fully operational nav lights, Cat engine sound, working fire monitors (one more still to fit!!), ships horn sounds, exhaust smoke generator (JJC), and working radar scanner. It still carries about 6 ounces of lead ballast and it is powered by two 3.5AmpHr 12 volt batteries. Its a great hull to work with, at the moment I am considering converting it to twin motors, presently it is single screw with steerable kort nozzle.(70mm). Twins would have to be 60mm. I am presently working out how to make a working towing winch. got to get rid of that ballast, it is a waste!!!
