Keel Time ;)

Hey guys
As some of you may know i have been making a model rc boat at school during my lunch break. We are almost at a stage where the hull is finished. I want to decide on a keel that i can use and make which will suit the yacht best.
The main problem is the limited depth of keel to just 30cm from the deck. This is on a 2kg boat with 70cm length and 2000cm^2 of sail.
The freeboard of the boat is about 6cm so this leaves 20-24cm for me to play with for the keel.
The balast can be upto 55% of the total weight so thats 1.1kg

What kind of keel would you guys recomend. A normal single fin or something more elaborate I like the sound of the V keel but unsure how easy it would be to manufacture on a scale this small.

Is it possible to buy wing shaped tubing that i could bend to shape perhaps?

I used to do a bit of RC 1meter class and alot of the home build projects used bulb keels.
