Military drone design

[Anonymous No.2008436]

Hi /diy/,
I want to design mlitary drone for school competition project

Main idea is to strap some rotors to the rpg/law style rocket launcher (prob need to be guided to match milspec) ruskies did sth like that and i want sth similiar
payload to carry is about 20 kgs

Any good radings about designing sth like that?
Need to be custom made, frame should be rocket launcher itself and quite big battery to power stuff

Any good readings about similiar projects?
If i win i could get some money and they might build prototype and test it:)
