The flying Bulls BA 105 Helicopter performed the most amazing Aerobatics. It has a fixed rota position (most helicopters have a moveable rota for control yaw, pitch amd momentum), and this design means they can do a full loop and be completely upside down. If a helicopter didn’t have a tail rota then it would spin out of control due to giroscopic motion.

Here are a few more aircraft from the Farnborough International Airshow. I look forward to when I can develop and upload some from my camera. These were all shot on my Huawei P10 mobile phone. Click on any photo to see a full size image.
