Why didnt you build an accurate version of the 1961 Monza?
An accurate 1961 Monza would be an incredibly difficult project not because of the banking and the crossover, but because of the graphics. Papys Monza is very graphically complex, and makes extensive use of large and complex three-dimensional objects (3dos) to achieve realism. An accurate and realistic banked Monza would have to be even more complex. Given the current tools available, the 3dos required are way beyond the capabilities of the average track builder.
