What do people think of this kickup T foil rudder setup?

The system is very simple. The T-foil is attached to the bottom of the main rudder blade, and is allowed to pivot freely. Referring to the sectioned plot below, the T-foil is also attached to the rudder box via a line that runs through the rudder blade. When the rudder blade is in the vertical deployed position the line pulls the T-foil tight against the bottom of the rudder blade holding it in a horizontal sailing position. When the rudder blade is released to swing to the horizontal position the T-foil is also automatically released.

Although this is currently shown on a Dotan stock (as this is what I use) it can be retrofitted to any existing kickup rudder system.
