I've also always liked the jumps on the ol' ideal,and now Auto world Dukes of Hazard HO sets.But I like the way the 1/43 cars run and run with little maintenance on the track..So,why not build a combo track with the road course,jump,hill climb and try to get it in a decent size space in 1/43 ? I've just about have the custom made jump completed..We will see how this works out....
