The Mavic folding size is great for backpacking, the specs look good on paper. What I don't like, is that for me, I need sometimes to hand catch because the landing is a no go, forget hand catch with mavic,also I often land in grass and the P4 clears it, with the mavic I would be cutting the grass. The RC looks like it's made only for a cell phone, I really like my tablet. I have seen P4's get smacked around and survive very well, not so sure the mavic's folding arm's can take as mutch as a P4. The P4 landing gear could break but they are cheap to buy and easy to replace. I would like a mavic but I would not trade in my P4 for one.
