Estes Leo Space Train Flying Model Rocket Kit: $29.72 $25.10 at NewEgg. This model rocket (which reminds us of the X-1 Experimental Spaceplane DARPA) will let you fly up to 300 feet.

Estes has launched its latest model rocket, the DARC-1 and not only is it the latest addition to the space corps line but it is the most challenging to build yet.

As with a traditional kit, both the nosecone and fins are plastic. Except here they’ve been 3D printed in either PLA or PETG depending on their proximity to he hot and fiery area of the rocket.

It's a pretty simple design---you can build it yourself or buy a kit. Here is a fancy homemade version of a water bottle rocket launcher (in slow motion). OK, here is one more water bottle rocket.
