I found this really cool model of the Tornado made by Thingiverse user TurboRenegade that was free to download, so I resized it to have a 6.25 inch wingspan (Roughly the size of the lego biplane for context) and printed it out. Most of the model is unmodified aside from the resize but I did made the shaft for the propeller myself in tinkercad. I did my best to give it a paint job to match the Sonic Adventure game model, it reminds me a lot of the papercraft Tornado bus since it's made out of plastic I don't need to worry about humidity or accidentally crushing it.
