Yesterday afternoon I experienced my first minor crash. It was a stupid mistake which I won't make again. To make a long story short, I was flying too close to some pine trees, without prop guards, and flying backwards so that the controls were reversed. I got distracted by my young kids arguing which broke my concentration. The next thing I knew my P3A hit some small pine tree branches about 8 feet up and tumbled to the ground landing on pine needles / tall grass. The only damaged I immediately found was that two of the plastic anti-drop pins from the gimbal were missing. When I got home I inspected the entire P3A for damage, replaced the two missing anti-drop pins, replaced all four props (as a precaution), cleaned the P3A with mild cleaner, calibrated the gimbal, calibrated the IMU, and calibrated the compass. Upon boot up I did not see any errors, etc. I did a short 2 minute flight and didn't see any issues. Other than the above diagnostics / repairs is there any thing else I should do prior to making another normal flight? Any advise would be appreciated.
