@superduperguy *Latest version of the python library

Thank you for the reply Michael. I have tested the quality of the batteries, and most of them appear to be good. I have checked the motor orientation on the drone and ensured that they are correct.One thing that is curious to me is that using the Petrone app we were able to make the drone fly stably for a single run. However in subsequent runs it no longer properly executed movement commands. Changing the battery on the drone did not help. We are using the latest version of the Codrone library found on Github.

Hello, my name is Parsa and I am a student in grade 12. For the past semester in school, my group mates and I have been working on using the FPV module and computer vision to guide the drone through our school. In the last couple of weeks we have ran into several issues with the movement commands. An example would be that if we use the command "drone.takeoff()", the drone will move upwards and then sway to random directions. After basic calibration did not work, we tried to correct the issue using trim values, but we find that the values we have to correct for varies for the battery that we use. We have also tried changing motors on the drone, but this has not helped the drone fly more stably.

A response would be greatly appreciated.
