ok, i confess i bought one for my 3 yr old son to play with in the bath.....when he was younger, from a UK seller by the way
thats the only place they work !- in the bath or in the sink !- i would never risk it in open water outdoors...it will be tears before bedtime if you do... they ship water easily,
the freeboard is minimal, the prop and motor is also tiny and speed is not tantilizing ! god forbid you ever encountered a current in the water or a ripple, never mind a wave.....- but the biggest problem is the radio !- it just said 27mhz....... and it seems it pretty much used all of it !
range was about 10 feet at best,
good fun for kids i paid about £5 for it all in- it lasted about 6 months
they charge from the tiny transmitter and run for about 1 to 2 minutes on each charge
