Regarding a spare prop for twins, assuming one was counter rotating . . . wouldn't it make sense to buy a Piranha plastic prop hub and then 2 sets of plastic blades, 1 std and one counter rotating set? (Assuming they even make counter rotating blades!)

Hi Ho back on the bus I go.

Got some Cobia today... Stop by the shop tomorrow.
Better stick to what I`m good at and leave science to scientists.
