Evidently there's a contest at Arrma factory tables , who ever uses the most lock tight wins !! I evidently have some clowns victory trophy subject , compleatly destroyed both front stub axlels getting the pin set screws out , in fact never got them out , stuff went all the way through the back end of the axels , tried heet and everything not a budget at all , very costly and very stupid , but hey ! I got a beanie on the way !
