Hi, I have a question. I know the z12 Race (not team) motor is made by SH. Is it a good motor to replace my stock GXR-15 in a fw-05? in my LHS the dealer said it has the same perfomance as the gxr-15. is this true? I'm planning on buying this since I dont have the money for the more expensive "team" motor and to train myself with .12 motors...
