Fun boat! This thing is a blast to run on a small lake and it throws an impressive rooster tail. Buy grease for shaft...it needs it every 3rd run if using it hard. It does not leak! The shaft sucks water, so seal the electronics and servo connections... For the money it is super fast and durable.
My son loves it. The thing really rips, turns very well, and is much faster than I expected. Battery life is relatively short at 8-10 minutes, but this seems to be the norm with RC boats. Maybe a battery with bigger ampere hours would help. The boat does require some maintenance, but not an overwhelmingly amount. The interior has stayed mostly dry and the self-righting function works well. Very good range on the controller and the boat leaves some battery reserve so you can limp the boat back into shore when drained.
