Nice thing about the vacuum forming is once you make a jig, it is easy to make molds. I wouldn't bother with this Gunship as it looks so excellent, there is no distraction. For cockpit canopies, it can be a big difference, depending on the model. The clear bubble canopies are a classic example of a need for vacuum forming, though I have seen people do creative tings. Chiawatkom makes a mold out of epoxy ( the positive side) and just heats the plastic sheet near an open flame and pulls the sheet over the plug it's all over in about 1 second, just using his thumbs!!
