That's difficult to say without more testing, since I hadn't designed them for this, initially. It would be easy enough to make the range the size of this settlement, but larger than that would require testing specific materials and techniques to develop.

[Once Kaveh has collected all the canisters, the butterflies still work just fine, and flutter around much more stably.]

These ones you have here were made to be as simple as possible in their functions, since they're meant to be easy to use. For something like you're asking, I'd want to take a little more time making them, to ensure the precision of it. I'm guessing this is a gift for someone?

[...Now that he's thinking of it, it wouldn't be the worst idea to make something like this for him and Alhaitham, either...]
