Instead of valves, why not use NOS transfer pump operates which uses a standard air pressure tank for operating power. My main question is why don't you use a standard NOS tank like those used in race cars for your rocket instead of building your own tank, remove the valve on those race tanks then remove tube that angles to tank bottom, put valve back on then those tanks will operate upside down. They make carbon fiber version of those race tanks. Then you can have race tanks filled before launch and load rocket with tank when ready to launch.
That could be an option, but I am pretty sure the racing NOS tanks are not 6 meters long... In the end when we do our space shot rocket that is how long our tank needs to be. So we are practicing all the things we have to do to make that possible. But a very good idea to reduce complexity indeed!
I'd say now it would have been easier with high test peroxide and an electric turbo-pump. Call me an idiot but I even would have tried it with steam or hot water under pressure. ((I always thought of mixing magnesium particles under the paraffin))
Well, just opening valves to make everything work is actually pretty easy. Electric turbo-pumps come with a lot of baggage and cost... But, pumps are usually much more efficient than pressure fed systems like ours. Could be a future evolution of our systems.
Your content is super underrated! Fantastic work! You deserve more attention and subscribers

When next amateur rocketry news?
When I finish my thesis... It is due next week so this is why the videos have been a little less lately.
