Hello there codifman. I am sorry for the trouble this has caused. With regards to the 30066 error message. Can you please try to perform these troubleshooting steps to see if the issue will be solved:
1. If the in-app flight tutorial is used, exit the tutorial and try again.
2. Try to take off the aircraft in an area where the GPS signal is strong. Please ensure that the propellers are all in normal condition.
3. When the GPS signal is strong, please calibrate the IMU of the said drone.
