RE: What prop if not APC
The weight of the APC prop is not an issue --
TheAPC is one of the least expensive props which hold shape while revvingup down
pick the right blade size and the engine will rev quickly
Just because a prop is light -doesn't make it a good 3 D prop.
There is a new clone of the Mejzlic now available in Czech Republic -extremely light - if tthat really is what you feel necessary
I think it is MZ
anyway two letters.
extremely light -look exactly like Mejzlic
