For all aircraft models that have been brought up to the new standard (so far: F5D, F11F, Gladiator, Marauder, Draken & F-18) there are cockpit kits available. But how to create transparent canopies for them, that actually look good, without too much difficulty involving smelting shaping and whatever. Here is a brief instruction on how I create clear canopies with transparent foil.
Choosing the right foil is very important: It should be see-through enough, easy enought to bend yet strong enough to stay stiff where it matters. It should not ript too easy but also not be too thick. I suggest testing a number of foils. Often foils around packaging from whatever products will work really well.
