So the prop guards seem like a great idea, but they're a PITA to install and remove if you want to store the Phantom in a reasonably sized case. Has anyone found a solution? I was thinking replacing the standard bolt with a standoff (like the one pictured) would let you attach and detach them in a single step without having to switch bolts. The only concern is the base profile of the standoff may not match the countersinking. Any thoughts?
