You will see a selection o' water rockets HD onboard videos. HDDV-MF504A is a very small HD camera with only a weight o' 94gr. Arrr! incl. battery and 8 GB card. O' course, it is a big risk if t' rocket crashes. Ahoy! I payed for this camera about 100 Euro. Blimey! Direkt imported from Japan by internet. Begad!
