Well there has been a lot of discussion about onboard video cameras. I was lucky enough to get my hands on two of the top end ones. The Go Pro Hero HD and the Vholdr Contour HD. So Ive decided to do a little testing between the two.
GoPro Hero HD
1080p @ 30fps
960p @ 30fps
720p @ 60fps
Built in mic
SD Card upto 32gig
Waterproof housing included
VholdR Contour HD
720p @ 30fps
480p @ 30fps
Built in mic
MicroSD Card upto 16gig
Lipo ~3hr Record time
Metal casing / water resistant
Things to make note of:
1) ContourHD sit lower, not affecting handling of smaller cars as much
2) GoPro films in 720p @ 60fps which is great for fast footage, though VholdR offers a ContourHD1080p version, we did not have that model available for testing.
3) GoPro includes a water proof housing
4) VholdR has a laser system for adjusting the angle of the lens, which makes mounting options almost infinite
5) VholdR has included software which allows for contrast / brightness to be adjusted as well as recoding bitrate.
Overall I think the VholdR is better for r/c just by the way it mounts. The case is durable, and its low profile mounting options prevents roll overs, which seem to be more prone with the gopro, though not show in the video...
Test footage is uncompressed footage from both cameras directly uploaded to YouTube. VholdR does provide their own uploading site, with the same features as YouTube which is pretty nice, but for this test i chose to use YouTube to keep things constant...
Here is the test footage, watch them in 720p for best results...
