If you don’t know what I mean with Z-003, check out the Z-001, maybe then you know what I’m talking about.

Anyways, I’m not having much ideas how the next Zeta plane could look like. But you could build concepts, or describe them.
They should resemble the old Planes, but a bit different. For example, an bigger version, or andvanced landing gear or engines.

Also, when my Z-002 is finished Publishing, (which I will say in the comments if it happens) look at it, since it’s basically an better version of the Z-001, maybe follow some of the new features it has, and add them to your concept.

When everyone is done, I will try to build the best concept.

Btw, I will say when it’s closed.

I’m exited for your concepts!
