Not too hard to make, as it turns out!
Take one Hotspur glider kit. Now throw away that canopy that appears to be a small model greenhouse...
Then cut off the rear fuselage, approx 1cm after the back door, and find a circular piece to block off the hole. Scoop out a slot for the wings on the top rear of the fuselage at this point.
Now we can cut out a slot for the nose gear / gun bay. This is where the cannon shares space with a vertically retracting nose gear. Any twin wheel 1/72 nose gear will do, along with any 1/35, or 28mm scale autocannon.
Now to gather parts for the engines. We'll need the Y - shaped part from the top of a 1/24th scale Pegasus engine, then, to the ends of that, we'll attach two 1/72 F-100 engine exhausts, and place the fan blade pieces in the exhausts. The whole lot sits upon the two halves of an Airfix Mig-21 tailfin.
The jump thrusters are a cut down droptank half, fitted with two small nozzles, and glued in place behind the nose gear.
To create the undercarriage, we'll cut the kit wings at about 1.5 cm out from the wing roots - we glue together the stub wing roots, and put them in place where the wings normally go. Now we need the u/c from an Airfix Mosquito, and attach it to the A - frame sections from an Airfix Lunar Module. Glue the kit elevators to the front facing side of the A - frames - these will become the canards when the u / c swings up into the flight position! Now fill in the holes in the ends of the stub wings with plastic card, and attach the u/c to these. Just need some wheels - F-14 ones should do just fine...
Glue the remains of the wings together to form one mainplane, and attach it to the slot at the fuselage rear. Now pin the engines to the top of the wings, and cut/find a fin to sit in front of the engines. Now attach your choice of wingtip / underwing pylons.
All you have to do is heat smash a new canopy now - before you fit it though, you must place a decent amount of weight in the nose, to offset the extreme aft placement of the wings and engines!
Simples!!
