oldbassard are you going to be flying from wheels or floats or both ? I have been flying only from wheels so far.. I would really like to see the lights reflecting off the water at dusk ..My Buddy has been flying his from both floats and wheels and he says there is no CG changes .. I am going to try mine off the snow this winter ..I love electric in the winter .. there is no cold goo blowing on your hands and the motors start much easier.. You can keep the batteries under your armpit to keep them warm ..
