Back History:
in 1918, the German Army flying corps, was looking for a new aircraft to train aircrews so they could learn to fly fighters much faster. once again it was Fokker to the rescue, When Anthony Fokker designed and build the D.VII fighter, he also designed an adaption of the fighter for 2-seat training. although the Germans prefered the C.I derivative of the D.VII, it wasnt a dual control aircraft.
the British were already operating such an aircraft at the time, the Avro 504, so allied pilots were trained much better then the Germans. so the trainer version of the D.VII, designated SD.VII, was more then welcome. Fokker build 100 Dual control SD.VII's for Germany. when the armistice was signed a few months later, Fokker lost all its rights to build aircraft, at least for germany. after the war, Fokker resumed operations in the Netherlands. the first post-war SD.VII were sold to the newly formed LVA (Luchtvaartafdeling = Dutch army aviation department). Yugolavia became the first foreign customer for the SD.VII, the Royal Yugoslav Air Force placed an order for 20 aircraft, later 18 captured german D.VII were converted SD.VII's. these served with the RYAF from 1919 to 1931.
the model:
the aircraft will be build from 2 1/72 Revell Fokker D.VII kits, i just sawed the 2 fuselages to salvage the needed cockpit sections. the conversion is quite simple, and thats a good thing about the old WW1 aircraft designs cause of the box like fuselages.
for markings, im gonna do it up in Yugoslav markings.
here are a couple of pics if the work being done



and here is how she would undergo for 2-seat conversion
