We've already recognized that there's an obvious overlap between aviation and "drones" (we have to remember that drone.SE is still defining what's on-topic for them or not):
- Can I discuss drones and UAVs in aviation stack exchange?
- Are questions about hobby-grade drones on-topic in general?
- Are remote controlled aircraft on-topic?
I suppose the key question is, is it a big overlap or not? For reference, as of right now (2020-04-21) we have 217 questions tagged unmanned-aerial-vehicle out of 18,369 total on aviation.SE.
Here are some questions that I think we need to discuss, there are certainly more:
- Most fundamentally, should we support drones.SE or not? That may seem like an odd or even hostile question, but there is an overlap, new stack proposals are fragile, and people's time is limited. Our support - or lack of it - could make a difference to whether drones.SE becomes permanent or not. Do we want it to be permanent? Would we be glad to send UAS questions to another site, or would we rather have them here?
- Assuming we do support drones.SE, what sort of questions do we send there vs. keep here? When we get a question that's clearly only about unmanned aviation, do we close it and direct the OP to drones.SE?
- What about those existing 217 questions? Do we close them, edit them to link to drones.SE, do nothing, or something else?
- How do we handle questions that have a necessary overlap between manned and unmanned aviation? Our top-voted UAS question has a deliberate overlap, for example. Do we need to define this more sharply and update our help pages?
- How do we engage the drones.SE community? Just glancing at their users, I don't see much overlap with our community. That may actually be a good thing because it suggests two distinct audiences for two distinct purposes.
Interestingly, I can't immediately see a question on the drones.SE meta site about how they view aviation.SE and the overlap in scope.
