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)
Step 1: Misc. Parts
Step 2: Fuselage
If you have any complaints about following this step, please feel free to keep them to yourself.
Step 3: Rear
If you can't see an image note on every picture of this step, it's bugged. Refresh the page.
Step 4: Wings
Build two of these (obviously). All panel pieces can be replaced by either a white snowflake piece (for the square one) or a yellow/grey five tooth (for the triangular ones)
Step 5: Final Assembly
Step 6: Finishing Note
So now you've made it, why not photograph your model? Modding is strongly encouraged, I deliberately tried to keep the frills low, to stop it looking too vulgar, and perhaps to encourage people to have a go, so better features and cooler looks could be achieved!
Here's a picture of a 6 engined variant. It has a skinnier body, no robot arm, two missile launchers at the back and an array of cannons along the fuselage. It lacks a robot arm, and the two extra engines have been removed. The engines can be slid off as they are connected to purple connectors. They clip back on just in front of the missile launchers (the two black triangular panels that are raised higher than the other engines. The fuselage cannons are the ball joint connectors on the blue rods. The second picture is the model from this instructable so you can compare the two.
Finally, why not build a hanger? I made 3 very small versions of this (twin engined), and made a storage tower for them. It was part of a huge moon colony I made, check it out here!
