Do any online stores have carbon props for 1/8" shafts? I need smaller sizes for my mini hydro. My pocket can afford metal ones and then go and have to buy a balancer and balance and sharpen them.
1/8 Shaft Carbon props

To use threaded Graupner carbon prop just drill out through the thread and plastic, with a 7/64 drill bit.
You can then thread on the prop onto a 1/8" threaded stubb shaft.
Works better if you run a 5-40 tap through it first.
I drill them out by hand on a piece of wood, With a new drill bit it seems to always go true.
