Need a little help with getting the C2 to operate properly on my bike. I'm a pretty aggressive rider and a typical ride has a lot of bumps and sharp turns...it's a pretty harsh ride on my sportbike. No matter where I mount the C2 on the bike or on my helmet, the recording will quit. I start the C2 on the internal battery and it records fine but the second I hit the throttle, recording ends and C2 will power off. I get a small file on the microSD card of only a few minutes. Is this normal? Are there settings to help with this? Of all my cameras, the C2 has the best picture and I'm hoping I can use it so any advice would be great! Thanks.
