I think the thing that would limit scaling down would be the valve. A
stainless 1/4" ball valve is about a pound without an actuator. With an
off-the-shelf pneumatic actuator it could be 5 lbs.

What's the smallest practical Hydrogen Peroxide monopropellant

Would it be possible to simplify and scale down a Hydrogen Peroxide
rocket so that it could be fabricated easily using off the shelf materials?
What would be the hardest parts to accomplish?
I realize that tiny Hydrogen Peroxide rockets have been used for
spacecraft thrusters, but that's not necessarily enough power to take
off from the ground.
I also realize that Hydrogen Peroxide in concentrations greater than
35% will be more difficult to obtain and not cheap. The smaller the
rocket, the less the fuel cost could be.
What challenges could be expected for something like this?
Have other people worked on similar projects?
Thank you!
