my dolphin stops after about 30 secs. Like you, curiosity got the best of me. I opened it up and tested all the motors. They seem to work fine. So I think it is the circuit board that sends out wrong signals. Is there any way to get new circuit board?
Thanks,
ADMIN REPLY: The circuit board cannot be purchased separately however you could try an electronics repair shop for a diagnosis
