You will see a selection of water rockets HD onboard videos. HDDV-MF504A is a very small HD camera with only a weight of 94gr. incl. battery and 8 GB card. Of course, it is a big risk if the rocket crashes. I payed for this camera about 100 Euro. Direkt imported from Japan by internet. If you want, visit my homepage swisswaterrocket.piczo.com
