Kinda rule of thumb: double the weight you want to carry and size components accordingly. Figure 18" minimum, not including prop disc outside structure profile. Bigger is more stable, but with gyros size could be redundant.

I have a couple motors that would support 10 lbs thrust, but not 100% duty cycle so you want to gang (correct word?) a couple more to reduce the motor heat load, but that significantly increases battery size, even more if you need to loiter longer than 10 minutes. Figure maybe 400 watt hours of battery, need to know motor draw to spec design better. Obviously more motors, more thrust, more complexity but more stable and bigger payload.

There's a couple trick questions thrown out there on the spotlight: 120k lumens is ok but what is the emitting device? Leds? 120 k lumens is about what one of my filament foglamps do each and the viewing specs are about the same. Not even hardly the brightest flashlight.

Oh and while I am thinking about it: AFAIK, there is no requirement for a red rotating beacon on a quad (even with 6 motors) strobes, and red, green, white position lights, yes. So if there's a red flashing light in the picture, it's an airplane.

I just did a search for duckduckgo.com/?q=largest+handheld+flashlight&ia=web. I saw figures of 100, 120 and 200 thousand and picked the middle number.

The 'World's Brightest Flashlight' Is No Joke: IMALENT SR32 Review
Jan 8, 2024The IMALENT SR32 weighs almost 5 pounds, has a shoulder strap, and can blast 120,000 lumens of light more than 2,000 m. This is the world's brightest flashlight, at least for now.

edit: The situation in New Jersey reminds me of the London Blitz or the Battle of Los Angleles. Instead of counter-drones or fancy auto-tracking ground units, an anarchistic neighborhood with a half dozen flashlights could triangulate anything in the sky, giving clearer identification, size and altitude information.

I'm assuming AI is required to track smaller drones to differentiate them from birds. If it hovers, or changes direction quickly, or does other things not consistent with bird movement, put a blip on the screen.

The birds with the FAA approved running lights?

Simpler than that: hobby radio now has a feedback function to tbe transmitter: about 1/10th watt. Won't work for inertial computer guidance stand alone, but 50 - 100 watts focused will fubar the controls of hobby equipment and the neighborhood web stuff. Destroys the signal to noise ratio.

Computer self guided does require GPS, so a transmission in that band fubars the GPS. Even some harmonic will suffice

Really experienced with having my hobby stuff shot down by random radio interference , not even in the same band.

I've been complaining about that for over a decade now with regard to highway diesel. They reduced the energy content, reduced the lubricity of the fuel so that lubricants must be added back to protect the fuel system, and made fuel cost more; for what? Acid rain isn't a problem here. I don't know a single person, who knows a person, who knows a person, that died of acid rain.

Then geniuses do the same thing to ships that burn their fuel away from everyone and everything, for what; to make global temperatures increase?

Maybe someone will invent a jet that runs on the discarded sulfur/oil mixture at high altitudes to introduce the particulates back into the air.

en.wikipedia.org/wiki/Stratospheric_aerosol_injection#Materials

Various forms of sulfur were proposed as the injected substance, as this is in part how volcanic eruptions cool the planet.[6] Precursor gases such as sulfur dioxide and hydrogen sulfide have been considered... Materials such as photophoretic particles, metal oxides (as in Welsbach seeding, and titanium dioxide), and diamond are also under consideration.

My understanding is informed by Erich von Däniken. The proper particulate matter is Gold. But the people who have cornered the supply are too attached to it to give it up.

Do solar sails work in only 1 direction? I assume so, otherwise we could have a reflective and absorptive substance that can maintain its orbit around the Earth.

I've been listening to Joe podcasts and went through the Triggernometry guys, Elon, and now Brian Cox. Brian quoted Bezos as saying "I want to zone Earth residential".

I just can't get into the news of the day, and specifically drones. Time will either reveal that mystery or it won't. What have we learned about China balloons other than they were made in China?

Here's my fundamental disagreement with the anti-humanists- that their argument is that Earth is best when humanity is least capable/willing to impact it. As a humanist, I find the earth is "best" (a human only concept) when we impact it to server our needs and desires.
