Flaps on KARO footy and over-powering the a rigg

We had a few days of good wind here in Maribor, SLO.
The wind on the pond in the city park was gusting up to some 10-12knots and shifty.
the trimm, the pivot point of the jib was set 4cm forward.

a crappy clip:

It seems like the vertical down force created by the sails is quite big in relation to the available volume in the hull. The boat gets pushed down upwind.
Obviously a solution for the next evolution of the karo is more volume, but i have also tried flaps below:

The flaps are at an angle which would be considered stupid with normal boats but at footy speed, or at such low renolds numbers it seems to be the most effective, and by eye it doesnt hurt the speed at all!

The flaps help to keep the bow up when over-powered upwind and reduce submarining downwind.
I noticed that leeway was increased with flaps. That was because the flow separated of the flaps and the hull, and then reatached at the end of the first half of the hull.
The midle third of the hull is the part where the chine provides the most "grip" upwind, so i cut the last 3 cms of the flaps, so the flow would separate earlier(from the flaps), and reattach on the hull after the first third so the whole middle third is immersed.

the cut flaps

Below is the clip of sailing with flaps, if the flaps do any good will be confirmed when i get another chance to put both KAROs in the water.
