Lipos,brushless motor systems,2.4 radios,way better plastics.So why are the local tracks,running track layouts from 30 years ago.Have not seen a single rhythm section where you must checkup as not to over jump and then floor it to make the next section.How about off angle jumps with off angle landings.Or any jump that requires a tap of the brakes in the air .I have just gotten accustom to supercross style tracks.Last time I went to topgear other than trying to set a really fast lap time ,track had no challenges to overcome,no learning to be done other than car setup.I like topgear would like to see more difficulty from the track layouts.Rc cars have come a really long way in the last couple of years,should not our tracks do the same.What do you think.
