Prop speed
My Droidworx AD6 with gimbal, Canon camera, FPV, etc. comes in at 10.5 lbs. At a hover the props sound noisy, as if it's chopping the air. Just a little more throttle and when starting to climb it gets very quiet and smooth. Currently using APC SlowFlyer 12 x 3.8. Do I need to go with a smaller prop and/or lower pitch so the RPM increases to get it smooth at a hover? What about prop stiffness, these are pretty flexible. It just sounds like it's working itself to death when hovering. Maybe a better brand of prop? Thanks.
Otherwise, it's flying great and we're getting some great photos.
