Hi there I'm new to site. I'm just getting back into rc cars again and I bought the cool looking subaru brat. But I'm kind of regretting buying this model as I'm having major problems with the front uprights. They keep separating and th wheels fall off. I've bought two sets already and I've got a third ready to put on. I was just wondering it there was an upgraded part or a single piece part to replace it with. As this problem is getting me annoyed now. Please see picture this is the same on both sides happened at the same time both fell off and it rolled to a stop.... Any ides would be excellent thanks in advance.....
