BTW, this is my only my 2nd plane. See this old plane (http://www.planetminecraft.com/project/massive-airplane/) to realize how much I've gotten better at building.

Here are my options.

Problem 1: either
a) remove the watermark and get a stampede of Russian sites copying my project, using my project even though their right to use it can be revoked
b) keep it and explore it yourself

Anyways, I learned my lesson about Russian sites. They never have a report button and without the watermark they copy it the SECOND it becomes popular. And if anyone copies this, the download will be taken down by me, including this project itself.

Problem 2: either
a) redo the whole plane and fail in school
b) keep the current plane
c) Constantly uplate the planes with new features and more realistic shapes and proportions (like I do now)

You can expect more realistic wings, wing base, bigger stabilizers and a bigger tail in a few months. This plane is big and updating everything takes a lot of work.
