Hi there, hope for some Q500 users even it's an old one 
my Q500 was stored in the case upright for several month, since then it has a real strange behavior: It lifts, starts jumping up and down. Gaining some height ends in a nose direction drift. Command "back" doesn't show any result. Right and left commands result in strange movements diagonally, but extreme slow and sometimes it does simply nothing.... Had some minor hits in between, new props are installed. Acceleration sensor and compass tried to be teached again. At the moment I've no trust into the 1800grams monster up in the air! Is here anybody experienced knowing possible root causes? Otherwise there is no really future for the q500, what would be a pity.
