Have you tried contacting Backcountry Cubs?

No,I havnt.I think Backcountry Cubs wouldnt sell blueprints to me because the blueprints maybe core secrets of them and even I bought the fuselage of theirs.Or its maybe very expensieve for I just purchuse the drawing.
For the industrial system is different,China run in metric system,the specification of pipe,aluminum,steel is different.I have to reform or restructure the drawing in order to can buy suitable materials.And the mechanical strength of wings.fuselage have to calibrate.
I thought they would have reverse-engineered a cub decades ago.
Nice machine but you need a thinner grinding wheel for coping the tubes. The roller for the belt sander would have to coincide with the tube sizes. Mostly 3/4, 5/8, 1/2 & 7/8".

I was also wondering how much american money for the machine you have pictured?
The dvd that i linked to that you can buy here is a 2 seat version without leading edge slats.
