Welcome to the Tornado club (just a few of us!). Have flown both a ducted fan and turbine version of the Master Fly/ITP model. Jet Mart (Ronnie York) here in the US has the molds on this and other Master Fly kits. More than happy to help you out just need specific questions. However, here is some key info that has worked for me and others: move the cg forward by at least 1" to 1 1/2" otherwise it is tail heavy and will tip stall. You can also add washout to the wing tips and put a rudder gyro. Mine is powered by a RAM 1000 with the BVM F-4 bifurcated tail pipe, fits peferct! Air Magic type rotating main gears ( al la F-15). Changed the wing sweep motor/O ring type to a direct drive motor with clutch ( Sears hand held portable drill with clutch). With wing swept you need to add 25% more up elevator (will become tail heavy as cg moves back). Hope this helps.
