Hi guys, I am happy to report that my P3S is flying well once again with the prop below that I got from Amazon. I wasn't certain they would be actual DJI props as I could not find any on the DJI website. They look and feel the same as those that came with my drone, but most importantly the auto lift off works like previously and it responds to stick commands as expected. I learned a lot from your help. The first thing I will do is down load and save a successful flight record for future reference.Thanks guys. I am in search of appropriate P3 replacement blades. I flew it again yesterday and it was slightly easier to control. Perhaps simply because I am unfortunately becoming more used to the flight problems. There is no longer a wobble (I ran the IMU multiple times) it continues to drift down and backwards. I am keeping my fingers crossed that it is a 3rd party prop issue. Stephen
Happy drone piloting,
Stephen
