How does this work? I can't find the instructions other comments have mentioned, and nothing I do makes this function as anything but a requestor chest. I cannot get the drones to fly AT ALL, the only thing the requestor port does is summon the swarm of logistics bots that I was trying to avoid to begin with.

thats cause it work using a logistic netwok
if the items you want it the long range delivery drone request depot are in the logistic network then it just works like a 2x2 requestor chest
this is made for like really long distance not around your base

first you place the long range delivery drone depot at the place where the items are made and input them into the long range delivery drone depot and make it so there is always 1 drone

second put long range delivery drone request depot at the place where you want the items delivered and in this depot set what amount of items you want to have delivered

and it should work
