Hi mark
you say the bebop 2 is second hand, do you know it’s history at all?
if not what I would suggest you do a reset, all you have to do is press the power button and when the light stops flashing and is constant hold the button in for 15 seconds then let go, this will take a few minutes and this should rest the drone, there are quite a few videos on you tube on how to do this, hope this helps good luck
