A Mod of Mining Drones that makes the following changes:

- Removed Iron Stick as a Crafting Requirement
- Changed Plate and Gear amounts for both recipes
- Crafting a Mining Drone now creates 5 drones instead of 1
- Increased Stack Size to 100 from 20 for Mining Drones
- Research is now required to unlock the Mining Drones

I highly recommend removing any Drones and Drone Buildings if you already have Mining Drones installed, saving your game, and then doing the switch, or you might end up with a couple hundred wandering Drones. They're fine in your inventory or a chest, but if you switch with them in world it does break the game a little.

If it's already too late, https://mods.factorio.com/mod/big-pink-eraser can be used to clean up the mess.
