My own is going to use a modified recompressive ballast system. Thrust vectoring for yaw, blended stern planes for pitch and roll control ( the batwings on the cabin induce a rather large roll moment in a turn and need to be canceled out to keep control otherwise when she rolls the yaw input turns ibto a pitch moment and down it goes out of control)and the midships planes for depth keeping. I used a ten inch Lee models as a test mule and once you get the static trim dialed in it tracks straight line very nicely due to the batwings on cabin. However they are to far above the CG and meta center to use as control surfaces. I tested them as both pitch and yaw surfaces and they induced a porpising moment when in pitch and a high speed roll when used as yaw surfaces. The sternplane tips are to far out and to small to be effective yaw rudders.
