All small rotocopters only get about 10 minutes per charge. My cheap and tiny Ladybird gets about 8 mins. They charge quickly though.

  I was thinking removable battery so you could have a couple spares and keep flying while another is charging, but now I'm thinking you might actually want that downtime while the fixed battery recharges, so the motors can cool down a bit.

    And to replace the broken pieces.
