How to make angry peds carry other melee weapons

[PL Hunter Blaze 0]

Well I wanna find out where I can edit what melee weapons peds will use when pissed off, when you hit their car. So far I figured how to make them use the original skateboard:

Like i want them to use katanas and chainsaws.

 

 

Also the planes that fly around, like rustler, and cropduster, I want others to fly around. The andromeda flies over Las Venturas and Los Santos, buti want it to spawn low like the other ones. So like I wanna make shamals, at400s, choppers, etc, fly too. I checked the main.scm and external, but I might have missed them. Any ideas?
