Nice vid! Did you know that with a little bit of 3M sticky velcro, the mQX stock will easily carry a 17g 808 keychain camera suspended from its battery tray? Flight time and climb rates are a touch reduced but you can still do large loops and flips with it!
Footage vibration/rolling shutter is the next problem, but nothing that a pair of hazard orange/foam earplugs lightly glued together like a velcro sandwich can't fix!
