I have tried two different camera’s on my son’s kart. The first was a Sony 8mm but because of its size was akward and got in his way. The second was a Sony DVR but I found that the vibration from the kart had a tendency to turn the device off. The “cadillac” of systems is available at http://www.chasecam.com. I recently purchased one and will testing it on the kart in the next couple of weeks. Regards.
