I recently bought a used Solo, #3. My pre-purchase test was getting satellites and arming without props. Good enough. My first flight was a new experience. Solo armed and as soon as it lifted started spinning. I was so 'surprised by the antics it took me a moment to gather my thoughts. By then it had flipped and was scooting around on my concrete driveway and broke props. Eventually the motors cut off. I did level cal and compass cal. Second flight in backyard -- grass. Did the spinning on liftoff, but I was ready and landed upright. Came to this site and found the same problem in a thread. Solution was to reset parameters to factory. Seems some character defining parameter was incorrect causing the spin. Third flight -- level and smooth. Lesson: Don't fly a 'strange' drone off your concrete driveway.
I need to learn how to analyze logs. I work around all kinds of high tech machining equipment, but haven't done a deep dive into the Solo.
