yeah that wouldnt work, otherwise helicopters would have already done it...

putting a pole into water thats flowing rapidly attatched to a 2000 dollar machine that weights as much as your monitor is a bad idea...

most all the nicer ones have Go Pro mounts, and some have the screens built into the controllers that come in the RTF's, expensive tho.... you crash that thing in a river, you just lost a minimum 1500... some of them are upwards of 8-10 grand....
