Average Thrust: ~200lb
Chamber Pressure: 500PSI
Burn Time: ~26

  • Oh DUH... you said class-N in the description :) But do you have any launch plans?

  • This is primarily a testbed for further research and development, I do plan to have a flight ready adaptation eventually though.

  • great job! are you documenting your work online somewhere? what type of ignition method are you using?!? congrats again:)

  • Thanks, I'm working on putting together a full write up on this project but I'm not sure if it's going to end up online yet. The ignition is a pyrograin ignition system that's mounted near the injector. Thanks again.

  • so this is about an N780. WOW! AWESOME JOB. will it fit in a 4" diameter airframe?

  • @JShifrin186 What was the size of the grain you used for this? single circular port?

  • that would cook a mean steak

  • Thanks a lot for the formula! Curious... what class is your motor & when are you going to fly it?

  • Awesome vid & a beautiful engine! Great work! I'm in the early stages of building a hybrid engine myself, and am having a little trouble with the nozzle design. Specifically the throat diameter. Any suggestions would be greatly appreciated.
