I had problems with the shock towers and bulkheads, but after i replaced those, it was fine. I also didnt like the stock shocks. I didnt get a chance to break any stock a arms, because i replaced them with rpms before i did anything serious. I didnt strip and gears, i guess i replaced all the gears with hop ups before i broke anything. I did have problems with the plastic sliders, so i replaced them with cvds. Of course, the stock cooling head got thrown out for an acncm head.
