Got an fc40 this week and I just wanted to see if what I'm experiencing is typical with the fc40 or just mine. I was flying today in moderate wind. It was pretty ok but as I was lowering it to sub 10ft altitude it was very wobbly and kept moving around maybe 3ft or so which made it hard to hand catch. Is this normal? Also I've noticed that the motors (or one/couple of them), sometimes have high shriek sound.. Like a jet engine. It's not super loud but not used to it with my p3. Can you guys chime in from your FC40 experience?
