RE: Propeller storage and carrier?
I keep mine bolted to the side of my flight box, kind of like what mild Bill posted. I drilled (2) 1/4" holes in the front of my box, just above the drawer and I hold them on with 2 spare 1/4"-20 nylon wing bolts and "wing nuts". When I'm headed to or from the field, I just turn the props a bit so they block the drawer and snug up the wing nuts. That keeps my drawer from shaking open while the flight box is in the bed of my truck.
