great!
You should now be ready to start the spinning!
When you spin the canopy you will notice a slight breeze underneath
as the canopy pushes the air down - this would be the way that
Leonardo thought it would work; the screw-like boring into the air,
pushing the air down, would propel the canopy, and base
- along with the pushing works into the air.
If you want the top structure permanently attached, then remove it
from the main shaft, add a drop of glue to the mast (in the hole) and
replace. If the drive shaft dowel is a bit loose, then place a small bit
of paper on the dowel and push the mast over it, that should
make it snug. Experiment! - if you don't glue the canopy on, you can
make helicopter propellors (from paper or foam core), remove the
top structure and attach them to the spinning shaft and see what
happens!
Fine tune the helicopter by making sure the outer ring is not rubbing
on the platform, by moving the collar up the mast if needed and
adding a bit of glue.
