I have been flying using the Wizard for a few days and I am quite pleased with its performance. Today while flying I stopped to change the drone battery and did not turn off the Wizard. When I turned back on the drone it took off on its own after boot up. It stayed close to the ground and flew slowly and ran into a piece of lawn furniture breaking two props. I could not control the drone with the Wizard. After reading all the instructions again I found nothing that indicated which order to use when powering up the Wizard and the drone. This is the only time that there has been a problem. I have since tried to replicate what happen and learned that powering up the drone first seems to be the answer. Any other users had this problem?
