I had the P3A before and recently bought the P3P. The professional i bought was second hand. It was used and the guy said it had about 10 flights on it. Anyways. The quad is flawless. Except one tiny problem. The Gimbal has the plastic pieces on all four corners inside the white squishy things. (Sorry for the poor terminology haha). Ive heard that theyre not suppose to be in all four corners, just two because it helps the gimbal be more free like its suppose to be. Do you guys think I should take off two of them? I don't know his reasoning for putting them on all four? Thanks!
