What are the differences of the mod 'Transport Drones' versus the mod 'Logistic Carts / Transport Drones' from here: https://mods.factorio.com/mod/logicarts3 ?

Does the 'Transport Drones' mod also offer 1x1 supply/requesting stations? They seem bigger (2x2)? Do you have to set waypoints for 'Transport Drones' or how do they find their way? Do the 'Transport Drones' see all the asphalt floor as potential ways?! Isn't there a huge UPS drop when you do a lot of pathfinding all the time?

(May look a bit funny since I am myself listed as author of the linked 'Logistic Cars' mod, but I only fixed something there and reuploaded it. So am I am really curious about the differences.)

The logicarts you need to program manually, the transport drones are more like logistic bots, and its much more efficient.
Pathfinding is quick because they only walk on the road tiles

Ok, thanks for the explanation :-) Sounds very cool! How to build the roads for 'Transport Drones'? Min x width? Max dimension of the road network? Which floor tile is recognized as road? How to build the roads so that it best suited for the drones?

And one more question: After installing the "Transport Drones" mod I got a lot of useless recipes in my FNEI now for example: 1x Transport Drone + 5000x Methane gas = 65.000 small alien artificact. Can be produced in suppy/request/buffer depot. Why are those recipes relevant?

This is determined by the nature of MOD. Supply/request/buffer is actually a factory. You can disable the formula of supply/request/buffer in FNEI settings.

Can you disable those recipes for FNEI by default?

This needs to be set by yourself. I am not a MOD author.

Sorry. I meant the mod author of course. Thus Klonan.
