Being new to my P3P a buddy flying got a white screen on the tablet, couldn't see anything. He dead sticked it and let it hover out of our sight. Punched return to home and it worked absolutely perfectly. I called my dealer and it took a few seconds walking me threw it to find out my buddy had accidently rolled the right side exposure knob and just over exposed the video or whited it out, nothing damaged or malfunctioned, just rookie pilot error. Man am I really glad I bought mine from a local dealer and tech support is just a call away, I am going to buy them all lunch.
