I travel with p4 4 batteries wind surfer, a 4in1 charger car charger (which is about 3x standard charger size) extra props, filter and sd card box and it all fits in an aftermarket turtle shell backpack which fits airplane carryon
With a mavic it would be lighter and smaller pack for sure, but it wouldn.t be like in the videos where everyone only ever shows the mavic and the controller no assessories and they show it kind of hanging out of their large pants pocket.
The implication in the review videos is it is like 10x smaller than p4, but i reckon in reality when packed with equivalent gear to have the same capabilities/flight times it won.t be anything like that
I.m also fascinated by the controller battery life. For those of us who fly 4+ batteries it is quite handy that the p4 controller has so much power i never have to worry about the controller or my tablet running out of battery.
The mavic controller is so small i doubt it has enough power to last many flights and keep a phone/tablet charged. We will have to wait till real users get it and review it rather than celebrity reviewers who have been specially selected to know about this one
