2 Rigging the Razor BAT Wing
Step 7: Correct Use of the BAT Wing
After diving both the Primary and Backup wings should be drained of any water
that is inside and partially inflated to dry.
Both Primary and Backup wings can be drained of water in exactly the same way
air is vented from them although it is easier if you orally inflate them a little first
so that you can force any water out under pressure.
