Hi Gaijin.

Im at work now, so I cant weigh the boat.
The batt 1500 kokam 3s pack weighs 105g, so I can insert plenty of ballast.

The motor was quite warm, but nothing to worry about. The esc and battery was hardly noticable warm.
So it cant be using that many amps. But I did not run the pack down. Only sailed for 4-5 minutes below 1/2 throttle.
