Good to test your motor and performance with. Also good to test some test flights, but not for permanent use. I Do not suggest to use permanently as it might chip without noticing and will break while spinning, with the result of injuring someone or the plane.

This is a great prop! I use it on my Electrifly rimfire .80 and it hasnt borken or chipped yet even after i've nosed the plane over. I only had to do some slight balancing. Very good prodcut, i will definitely buy more!
