why don't you use an external retaining ring? You correctly used an internal retaining ring for the nozzle... You should use an external one for the tube. Installation is faster, easier, and won't scratch metal!😁
Yeah, I've thought about using an external retaining ring, but I think there are some good reasons to go with the spiral ring. It's meant to be permanent, so you only have to install it once on the casing and then forget it. Also, it's lower profile; I'm not sure the retaining ring would fit into most motor retainers. Finally, the spiral rings are the industry standard for this type of setup so there's a lot of experience behind using them.
I haven't tried it yet, but would like to some time. It seems like all of the ground support equipment would be a big investment, and we don't have anybody at the launches I go to doing it so it would be quite a learning curve. Maybe I'll do one eventually.
Why your testing video about rocket engine test is a little, also use different oxidizer, i have Urea Nitrate at home and want to use that as a oxidizer than ferric oxide (Fe2O3) but i does not know how to use it and what's the presentage to making a rocket engine, and can i just dry mixing the substance than melt it?
Hey that's me! Thanks for the update. Super informative as always!
Where do you get these rockets and cases? Seems like a cool hobby.
These cases I machine on a lathe, but you can buy similar cases at lokiresearch.com or at binderdesign.com/store/Fisher-Research.html
Where did you get this thrust ring?

have you tried making a hybrid rocket ( a medium sized one ) that seems to be all the trend now. TQ

@@MinuteRockets All the best .There is a German university that has attempted it .Good luck.

What is the materials for the motor
Mostly aluminum. The nozzle is stainless steel.
You can see the full build in this playlist: ruclips.net/p/PLiGX5Ym4VS5hjKwN8SVjDV7LSlACWIpVO
Are Arduino install in this rocket
I havne't done an Arduino. I usually fly commercially available altimeters.
