Thanks for the info, The unbalanced prop is probally the reason the stock gear box and motor didn't last. I did some more research and read the reviews (excellent reviews). I think I will get the 450BL. I like to stay around 400 size motor and the specs on this will allow a 20 amp ESC (I already have (3)BL 20-25amp ESC) and this will keep the price down when I swap out motors.

Next I think I will swap between the 450 and the Himaxx 2816-0890 to see the difference between them in the same plane. The specs are close to the same.
