I did a crazy, stupid thing yesterday. I took off with my P3A & noticed that my Pilot app only showed about 8 Sats. While looking at the Controller I momentarily took my eye off the drone which clipped the branches of a tree some 15ft up . My P3A tumbled to the grassy lawn. I wiped off the grass stains & noticed a couple of niks in one of the Rotor Arms. The props seemed fine but one of them was just touching the arm as it rotated. I guess the arm is slightly bent. I put a little pressure on it to try & stop it touching which successfully worked but the prop rotation is still too near the arm which to me would put the drone out of balance. I did a test flight & all seemed well. It did however seem a bit twitchy which could well have been the slight breeze. However, I am concerned about the prop clearing the arm less than the other three. Any suggestions?
