Canadian Navy Grumman CP 121 Tracker

A friend of mine asked if I could make a Grumman Tracker for his father who was a former crew cheif. I can't see why I wouldn't be able to do something up for him. The Canadian Forces has a Tracker on display at the Shearwater Air Museum. That is great news for this build since the museum is a 15 minute walk from my house, I can see the actual airplane I am trying to recreate.

I found a pretty good diagram at https://ingeniumcanada.org/

1. I first cut out multiple layers of Coroplast® that I will stack to make the fuselage. Wider areas of the aircraft will get more layers
2. At first I thought the folding wings would be a problem. By turning the sheet slightly one swipe of the knife makes the perfect folding wing
3. The layers of the fuselage together making the basic shape

4. The engine / landing gear combination was tricky. There are so many different angles and shapes to combine. I had no choice but to make it in multiple pieces.
5. There they are assembled. There is a notch cut out to fit around the wing. I filled in the gaps by using the glue gun like a 3D printer. Adding multiple layers until it is the shape I need
6. Fuselage, wing (with light), horizontal stabilizers, engines and landing gear are all together. It is time for some assembly
