Corsair

thingiverse

This is an F4U-1D Corsair that I designed for my design and engineering class, modeled after its real-life counterpart. The wings fold up just like they do on the actual plane. My model is close to 72nd scale but isn't exactly that size because printing the front part was tricky - it had to be made as large as possible within the class's size limits. I recommend attaching the propeller blades as late in the process as you can to avoid breaking them, and I used copper wire for the hinges to act as a pin.
