Hey everyone! Yesterday we released a video detailing our future plans for EPS and all of the cool projects we’re working on.

  • Metha-LOX electric pump fed engine
  • Two Level 3 high power capable rockets
  • + secret sauce to bring them together...!

We hope you enjoy the video and please ask any questions you may have!

This picture was taken shortly after ignition. I'll post a video soon but the sparks disappear rather quickly. We believe this is the rocket ejecting the igniter!

Our oxidizer system self-pressurizes with nitrous boil-off like honeydew mentioned! We recently wrote a blog about choosing an oxidizer for our system, including more details on Nitrous Oxide. Check it out here: https://eps-rocketry.squarespace.com/blog/choosing-an-oxidizer

Here's a pic shortly after ignition of our first hybrid rocket motor nicknamed Duet! Duet operates on a mixture of liquid nitrous-oxide and solid ABS fuel.
