Investment in the ancillaries, or ancillaries of ancillaries-vendors of famous companies

Thanks. So grateful.

No, you have not misunderstood. Only issue is, the .coms are not listed.

I am sure Idea Forge or Zen do not buy the propellers, controllers or the motors needed to fly these drones. So, are there any listed companies supplying these parts (atmnirbhar) or they depend on DIJ like Chinese companies?

Of course, my hope is that the thread expands and we get inputs about various sectors or companies. And hopefully, if there is a simpler way of locating such companies.
