The aircraft you have pictured has leading edge slats. as Ed stated they are for additional lift in high angle of attack manuevers. The aircraft pictured I am sure has computer controlled slat deployment. Puting control sufaces on the leading edge of the elevator or rudder would be almost impossible with the material used in our hobby. I'm sure that the newer digital servos would have enough power to move them but the structure needed to keep the movable surface in place would be heavy and and hard to build. As randy (rryman) said I like to experiment with all kinds of models and configurations. Some worked and some didnt. The swept forward wing airplane i have does fly nicely, but roll rate is allmost a blurr. When first built it 15 years ago, I didnt have the opption of a computer radio to help with mixing and exponential rates. These features have tamed the beast to a very nice flying aiplane. The germans had swept forward wing jets on the drawing boards at the end of the WWII , but they didnt have the materials needed to keep the wings on the airplane at that time. A forward swept wing wants to rip right off the at the tip. Carbon fiber and titanium extrusions used by the Russians and the US in there respective sweep forward designs have made these aircraft possible today. But they too have to be flown by a pilot that inputs the controls into a computer and the computer moves the control surfaces needed in the correct direction to make the airplane flyable. i have pics of the forward swept wing plane, but this is twins and multis so i'll not post pics of it here unless asked to do so by the group.
