After not using the drone for 2 months, I encountered two problems.

1.        P3P will not execute initial lift-off by advancing throttle.  Will only lift-off using slider.
2.        With card inserted, any attempt to take a photo cause “Empty Card” message to display.

P3P worked just fine 2 months ago.  

Any thoughts?

Just tested this AM.  Seems to work except for "Weak Image Transmission Signal" ??
