I have my tello for 8 months now and it worked fine all the time. I didn't use it in the last 3 months and wanted to fly it again. When i took off, the motors went to full power and stayed on full power. My drone chrashed into the ceiling and fell back down. A reset of my drone didn't work. Drone was up to date. Never had this before, does anybody now why this happened and how to fix this?
