I haven't needed the quick change ability really, but it does seem like a PITA. Flimsiness does seem like a consideration for sure, but I guess that could be true in the bigger birds too.That prop attachment method sucks. I remember having experienced changing props on my mini, quite often as it's the drone I learnt flying on (hence, lots of crashes, I even cracked an arm), and there were always issues with balance and flimsyness (even when changing both blades as a package-matched pair too). It also requires a tool and it's not quick-detach capable.
