Yes,this Rafale kits is originally designed for duct fan and "she" is very suitable for the 12 to 14 lb turbine,like super Bee,P-60,PST 600,etc.The parts you should to change are that you don't
need to insert the inlet duct and the space are great for larger fuel tank(because it is near the C.G)(about 2 litter in my Rafale).Another changed part is the dural wall exhausted steel pipe.Of course,you need stronger retract gear (can load the 8 to 10 kg weight) with brake;Perhaps you should built your wings with thicker glass covering.Trust me,she fly better with turbine than duct fan!
