between me and my father we have around 30k worth of rc cars and boats. carbonfibre 1/5 scale onroad race cars with 23cc komatsu petrol engines fully worked in the usa running 4 wheel hydrolic disc brakes with xdrilled and slotted rotors, 1/4 scale sprint cars and 1/5 1/4 scale boats 100mph. my fathers more into the boats but I finished 18th in the femca world champs held at morebank nsw in the onroad car about 2 years ago. in 2005 I was leading the club championships untill u did my back in and havnt competed seriously since then, after the old man had a stroke last year the cars dont get much use now but he can drive the boats with one hand as the perallisus has only been limited to one side. so year im into rc cars 4 sure
