Hello! My name is Micah, and I would like to thank you for visiting my project! I'm a big fan of aviation, I remember the first time I flew and what a thrill it was, and since then I've been what you call an "aviation buff." I was very excited when Lego first introduced the City Airport series, but as I soon noticed a critical piece of airport equipment was missing: the airport tug, or at least a decent representation of one. Through a lot of research and playing around with ideas, I finally came up with a design I liked and this is what I came up with. The tug is compatible with sets 3182, 7894 and 7893 with very minor modification to the wheels.
Once again I'd like to thank you for visiting my project! And I hope that if you like what you see you'll support me and spread the word about my project! Also, if you feel that I could add/remove something to make this even better, please feel free to drop a comment!
P.S. Apologies for the poor image quality.
