I think I found a great camera for taking onboard pics and vid. Check it out http://www.kodak.com/eknec/PageQuerier.jhtml?pq-locale=en_US&pq-path=12417
If you think the quality is good here online, you wouldn't believe how good it looks when it comes straight off of the camera!
It was pretty cloudy and kind of foggy this morning and we all know how digital cameras handle low light... this one did well with it.
I was able to cruise around at half speed with my Super Cub (lipo and 10x6DD prop, otherwise completely stock) Loops were easy as well. I believe that this camera weighs about 5.5ounces with the card and lipo installed.
