do you have any challenges right now? I don't see scaling issues different from the average hardware-enabled company. I'm usually scared of hardware because stuff can break without my fault (I want to alwasy have stuff break because I messed something up, not because some bad weather destroyed 30% of my drones), but I imagine in your case the highest focus would be on tracking defective drones' location (you need to store their positions, and all kinds of stats like battery), need a fast-track to repairing/replacing them etc. after a while their batteries deteriorate (you can basically track how fast batteries discharge and you'll have a graph for each drone and need to decide a threshold where you're intervening to swap the batteries)

I'm not an expert on drones, but I imagine you'll have a backend of some sort. if you need teammates, we can talk
