we got approx 12-13" wet,soft snow here at moment. Neither floats or ski carrys a plane on top for take-off, or ok landing. But nice day to try out a glide by the Yokosuka. Approx 1150g total weight with a 2700mA battery, retracts, GPS stabilizer controll, eg. approx 150 more with the floats on. Glided nice, and easy setup CG control, i belived it could be needed more forward weight, but no. Then the battery get a perfect placement.
Some "taxi" tryout into garage was done. It got great power... but see need of steering on the tailwheel, for better direction control.
