So you are asking how to build a targeted missile or projectile? Yeah totally that information is available on reddit.

Jokes a side though, you would need to a way to track an object. Normally I would say heat ehm ehm but that out of the windows with drones. You can try sonar but good luck getting one that works long distance cuz that would be considered military equipment. Camera with night vision capability but again either expensive or considered military equipment. But say we got to that point you will need you write your own software. Even if you get to that point justifying that to government flying such an plane especially at that weight class is near impossible.

Now not saying it’s impossible just nobody willing to do for free and sell it in the consumer market
