I can't tell which this is... I ran the numbers and uhh.... According to wiki the U2's wingspan is 103 (feet) wide so I multiplied that by 12 to convert into inches then divided that number by both 48 and 72 and got 25.75 and 17 (and change), respectively. The box says it has a 20 inch wingspan. Either I'm not doing my math correctly (although I've checked it on models before and it lined up) or the U2 is an oddball size, or the box is full of milarkey. LOL Googling the kit tells me it's 1/48 so I'm going to assume that's correct and the people who made the canopies know what they're doing.

Thank you for the tips on canopies, I found one (Squadron) for a bit over $10 U.S. so if I can't come up with the missing one or find a really good alternative method.. I know where it's at.
