I had a problem with my P40 Robarts .I used my own money and federal expressed them back with a very nice note explaning what was wrong . The gear had a manufactured defect that another modeler verfied .
My note indicated a very nice "please " in a rush would like to enter a local stane off scale event . Gave them the dates , withen 4 weeks ect .
They never called , emailed or even cursed at me . IN week 4 I became "lets just say angry "and I recieved my gear the next week .

It was then that i decided to always buy century unless , there was another option for rotating gear .Please remember I spent my money to ship back there problem .
