Hills

I really want to do Spa in Belgium,it's one my all time favorite tracks to race, but it Requires some hills, so I started experimenting and came up with this, so far

0 to 10 inches in 84 inches, which it good, I still need another 84 inches at 10 inches tall, then make that right turn you see, then Descend. Spa will need a hillside to do it right, so maybe a Landscaped hill will do the trick, we shall see
