The very first paper model kit I ever developed was at the request of user GEEDUBBYA on the paper model forum at Zealot.com. He had found a 3D model of the Airtractor by Ronnie Olsthorn, obtained permission to use it as the base for a paper model, and then started looking for someone to create the paper model kit. If you’re interested you can read all about it, or just scroll on down and download the model.
For my first effort it turned out very well and I’m quite pleased with it. Pictured below is the 1/48 scale version. It’s also available in 1/72, and soon I hope to release a tiny (1/200) version, just because I can. The textures on this model are low resolution, but if there are enough requests to motivate me I’ll redo them and make a new version.
