A few weeks ago I was flying and it seemed like the Phantom was tilted to one side when hovering. I thought it was just my eyes playing tricks on me but today when I installed my new prop guards it looks like both props on the left side are about .25 inch higher than the right side. I'm assuming this isn't normal. I can't really figure out what caused this, it's strange that both on one side are raised up higher. The shell was replaced by DJI back in January, maybe something wasn't installed correctly? It's been flying ok, maybe a little unstable.
