I live in the U.K. I bought a Go Pro Motorsports Hero video camera direct from Go Pro. I told them everything about my racing car and they showed me a link to their camera being used on a single seat racing car. It works OK and records up to 50 minutes when used in the house or garden, or when mounted to the dashboard of our road car. When I mount it to the rollbar of my single seat racing car, using the Go Pro rollbar mounting, I get this problem. The camera starts recording but stops after a few seconds. The longest clip I have got is about 30 seconds. When it stops, the red light remains on continuously. Neither the record button or the on/off button do anything when pressed. To turn the light off I have to remove a battery. The memory card then contains one clip. Most times, that file is 0 bytes and unplayable. A couple of times, the file has been 30 seconds long and playable. I have tried encasing the camera in aluminium foil to see if there is an interference problem with the engine, but that makes no difference. We run a transponder for lap timing, like everyone else in the U.K. Disconnecting this makes no difference to the camera function. I have Emailed Go Pro, asking for help. But they do not reply.
