Ask yourself this one simple question are you willing able to spend 30-60 hours just building the kit this doesn't include an extra 5-10 hours to get you to the point where you know how to fly just well enough to be dangerous. Nor does it include what ever time it takes you to write up your report and what ever else your teacher requires for your project.

Maybe you could pick two or three airplanes that had a significant role in the early days of flight during the 20 century. You could build a plastic model of each and describe what made that plane special.

I don't mean to burst your bubble but I don't see you being able to finish your project even if the deadline is extended.
