Cheers mate, I decided as these are both space and atmosphere fighters they didn't really need tail fins or indeed even traditional control surfaces...they use processes called Circulation Control and Fluidic Thrust Vectoring (FTV) which are actually very real, but currently experimental ways of controlling modern aircraft.
Jets of air along the back edge of the wing change how air flows over the it. This can be used to induce the air flowing over the wing to flow around the back edge of the wing instead of simply flowing past. This produces more lift. By turning off and on jets strategically placed along the trailing edges of the wings, the pitch and roll can be controlled.
I have modeled my own version of this onto the engine cowlings just above the wings using part of the Hurricane Bolter assembly.
Fluidic Thrust Vectoring
Most next-generation fighter aircraft have, or will incorporate, some form of vectored thrust, enabling the pilot to control the direction of thrust from the engine. This greatly increases maneuverability and control of the aircraft, however, conventional vectored thrust technologies require a lot of complicated moving parts at the business end of a jet engine. FTV simplifies things by deflecting the thrust of the jet engine by injecting a higher pressure jet of air along the nozzle wall. This secondary jet deflects the thrust of the engine.
I didn't have to actually model anything for this, however, as a bonus GW nicely modeled what look like thrust vector vanes onto the eflux nozzles of the engines.
On my model these are actually going to act in a couple of capacities. As air-brakes (I envision them all opening like the petals of a flower) but also as control surfaces controlled by the machine spirit to stabilise the fighter in atmospheric conditions. The machine spirit will also independently control thrust from each engine to help control yaw, similar to the way the real life B2 Spirit Stealth Bomber is thought to do.
I am hoping to get on and finish up the second one of these fighters I am currently building and documenting for a tutorial. Life has been getting on the way lately so I need to make an effort.
