Leonardo's secret weapons used during his time

Right here in Brisbane at present is an exhibition on the inventions of Leonardo DaVinci- so WI at some point during his lifetime, some rich nobleman decided to become his patron to have 1 or more of these inventions (such as the tank or helicopter) actually developed & used ?

Allot of the weapons as drawn simple wont work espeicially the helicopter it wont get of the ground. The tank will only work on flat ground and it will be tricky reloading those canons in such a confined space.
