I'm not sure an HC-05 is such a good idea for a rc boat<...>
I was wondering about that myself but figured reality would come to roost if the boat was in anything bigger than a home swimming pool... or the bathtub! How nerdy would it be to have an RC boat controlled by a water resistant iPhone 6 in your hottub? (Probably be crown-sourced tomorrow!)
