Managed a little faster.... 49.23 mph - http://www.flytrex.com/mission/quadcopter-dji-phantom-fc40-simon-hardman-51504/
Ohary said:I flew in ATTI mode and managed to add about 7 mph. I'm at 57.18 and into 3rd place for FC40. I could easily top 60 as that was my first and only try flying in ATTI. All you need is a 25 or so MPH constant wind to do so. The Phantom will do 40 in calm wind, my only fear is losing the sucker which is pretty easy to do at those speeds, lol.
