How do you balance the new self tightening props

[Ronaldtrotter]

The new Phantom has self locking/tightening props. How do you use the balance tools to balance these props.

you need to get a bolt or such with a long shank, with correct threads (not sure of size) and use DuBro large prop method, see vid at 11:30.

or another method, but use the threaded motor top.
