The Cobra Transport helicopter, unofficially code named "Cicada". This toy only existed in the comic books but I loved it as a kid. The model was a real challenge because it was shown in about 8 or so comic book panels but the design is not the same from picture to picture. And, not every angle is shown so I had to improvise parts of it due to lack of information. In any event I’m happy with the results.
The file was created roughly full scale (there was never a toy for this) it is optimized for printing at 25%. Unless you stay in that range your print may have too much or too little detail.
My finished model weighs 25 grams so it cost me about 53 cents for the material to print it.
This model has quite a bit of support material to remove after printing due to the overall shape of the helicopter. Removing support material is not fun but neither is gluing delicate wings and things together.
Special note there is an alternate rotor assembly should you not be able to fit the one-piece design on your print bed. I test printed both of them but I would use the one-piece if you can manage it.

Much respect and gratitude to past and present members of our Armed Forces, you are the “Real American Heroes”. Your sacrifice allows people like me to live in peace, freedom and make silly little toys like these.
