This is a spacecraft/plane I made from knex, called the phantom. It has a robot arm which is very manoeuvrable (using ball joints), an internal sloped runway and two rotating cannons.
I am posting this because it has good aesthetics, is sturdy and robust, and is simple, so many people can build it. Also, I think it would be cool to see more planes and rockets on this weapon-infested site.
This is a deliberately simple plane, so it will be very easy to mod. On the last step, I will show you a larger six-engined variant, although it is uglier, skinnier and rather cumbersome. This model is much more refined and shaped better. Feel free to post a photo of your model below, It would be cool to see this in original or full metallic colours!
Lastly, would people like to see more of this kind of stuff? (i.e not guns)
