  • did you make that engine from the thermite used in the Sparkler fireworks?

  • Sparkies get their spark from Ti sponge which continues to burn white hot after exiting outside the motor chamber.

  • Hey guys, I make rockets too and as I gradually work my way up in size I need to know how to classify or name my motors. This video says it's a "M" motor. How do I find out what my motors are? Is there a formula? Can you make it past size "Z"? Your help would be very appreciated!

  • Go to tripoli (dot) org/tmt/motor_classes (dot) shtml

    Note for every letter increase is a doubling of power.

    How do you not know this formula if you're making motors? It's a most basic knowledge to get things correct. You may wish to do some more research to keep safe.

  • where do you get these kind of engines?

  • Jerry has spent many years perfecting his motors, it's EX, built by the flier.

  • @HarrisonsChannel they only make up 2 P. Anything above that is experimental. If you are an 8th grader like me and you launch anything high power(Some G's and up) you get good props for college choices

  • Awesome video

  • @VooDooRocketry I completely agree. It's not too hard to learn! There are plenty of great resources out there. Have fun and fly safe!

  • @skinnywhop87 they dont use thermite there is similar reactions though

  • @HarrisonsChannel Yes, you can go past Z, it starts over adding "A" first. Space Shuttle Boosters are AC I believe.

  • Whatever

  • nice launc h. i love the slowmo

  • yes, once you go past z, it starts over at aa, bb,cc.... I am currently on ccc
