I'd like to see more purple stains on the launch pads.

No, a catalyst is not required. But the ability to use a catalyst is
what redeems some of the hassles of dealing with a monopropellant.

Is a catalyst strictly required for peroxide biprop engines? I wouldand
think that the decomposition reaction would self sustain after
ignition, but I don't have any experience with peroxide.

For a flight weight vehicle, its hard to build light weight LOX tanks,
pressurizedthe valves for LOX are a continuous problem with
small valves.
Also if you factor in the price of Helium I think that peroxide
hydrocarbonwith Air or N2 is lower cost than LOX.
The Lox is almost free, the Helium not so much....
Also no hardstart issues, it just lights....
the O:F is ~ 7:1 and the O is the coolant for Regen, small Lox
Lox.regen motors are hard and need film cooling,
with Persoxide I'm runing a 100lb regen aluminum motor with no cooling
issues (so far)
You do have cat pack issues...
You can get you oxidizer and store it for log periods... not so with
rocket
I like peroxide....

Where there some details somewhere? Yeah, I think Paul had a better
source for peroxide than Armadillo seems like a lot of Armadillos work
was done with lower concentrations at least on the bigger motors.
Peroxide/gasoline or kero would seem to benefit from jet engine
technology. Basically treat it like a jet ingesting a lot of water. I
wonder if an annular combustion chamber can be made to withstand the
heat?
That would be reinventing the wheel right now which I'm wanting to
avoid.

What I see so far is a lot of unstable motors with asymmetrical
issues.
Check out Paul Breed's peroxide/gasoline engine that flew on one of
"lander challenge" vehicles: that seemed to be a smooth-running unit
(though well under the 1000 lbf. you contemplate here).
