It is a very fun little boat. Mine floats fine with a 400 Feigao brushless, Hacker 40 amp esc and ten 2/3A 1400mah batteries. Although I am taking out two of the cells, its a little over powered. (Understatement of the year) lol The next thing I need to do is either find or have someone make some micro trim/turn fins to help keep it under control.
