4.5 Stealthy but very fragile coling1953 | 07/03/2012 | See all coling1953's reviews (1) This boat performs reasonably well but does not match the write ups or the hype. Battery life is about 10 minutes on a full charge and it nips along fairly briskly. Mine has never turned as sharply as some of the videos suggest. The main problem is the very fragile hull, it is made of eggshell thin plastic which literally shatters on the mildest of impacts, I have had to repair mine twice so far with superglue and P38 bodyfiller then spray it up. If you are serious about getting into R/C boats this will give you a cheap taste, but you are best advised to save your money and buy a better boat as this is not much more than a toy.
