Cheers! But I thought it had 'XH162' written all over it?
Nice model to build - realy just fell together like it was meant to be.
Take one Airfix Mig 21, and assemble the fuselage as normal, the nose from an Airfix Mosquito, the missiles from an F101 Voodoo, the glove pylons from an F14, a small round drum shape, and whatever suitably sized rotor blades from whatever toy helicopter you can find (mine has folding blades - bonus!)
Then trim down the wingtips to the outer fences, use one of the pylons to mount the drop tank over the engine bay, then fit SNEB rocket pods to the wingtips. Place a spare afterburner on the exhaust, then cut the Mosquito nose to fit snugly onto the spine of the Mig, and cut a hole to fit the drum shape into. Then glue the base of the rotor hub to the top of the drum shape, and slot it into the Mosquito nose. Job done!
