How to build a simple hybrid rocket engine

This is a video showing how i built my first hybrid engine, it runs off of polyethelene and oxygen. If you have any questions please post!

can you scale this up and make it propel a model rocket?

i want to make a liquid fueled engine i have all the machines and tools but do i need supercooled or compressed liquid oxigen?

@soverato3 You can scale the idea but not the parts. If your going to have a small liquid engine you really don't need to cool it, you just cant run it for a long time and you will probably have to build in some type of heatsink to dissipate some of the heat. You don't need liquid oxygen for a liquid fueled engine you can use gas, the only reason they use it on real rockets is because you can carry much more than gaseous. If I were you I would do a lot more research before building.

How would you attach this to a hobby rocket? Could You make a Video Pls?

[jrbpyro101]

@TheJMAN12365 This particular engine isn't made for model rockets, there just simply is not enough power. I will eventually get some videos up on larger homemade engines but other hobbies have taken priority.

hey man good video but do your self a favor and learn the "iron pipe size "nominal measurements so folks ask for the right stuff at the store. 1/2 id ,5/8 od threaded pipe and fittings is 1/2 inch I.P.S ,just a plumbers input

but other than that great work

@jonasreinoso1 Anything's possible my friend. :)

can you make a video on how to make a parachute unit so it doesnt smash to pieces

Where could I get o2 or nos?

@M4DJE ok.. i want to make a 2stage giant rocket with a liquid fueled engine as second stage. i was thinking of using liquid oxigen and liquid butane or propane but if you think rc car fuel (25%nitro?) will work better... ill give it a try! :D thnx for the info i will let you know when i have tested it :D the engine is nearly done

so testing can start soon =) its a V-2 based engine but scaled down to +- 50kg thrust (hopefully haha)

cheers :D

@soverato3 u can also use rc nitro car gaseline/diesel but becareful its highly flamebale

if u use this type of liquid make sure evrything is closed tightly but anyway u can make on more ways a great

rocket engine this methode is very easy but very dangerous i wouldnt choose it if i were u
