I'm envisioning that we get quite a few questions regarding remote controlled aircraft - how should we respond to these questions? Are the on topic? Or do we want to keep the site to only life-sized aircraft?
I think they would be on-topic if the question is regulatory in nature, such as "can I fly this here?"
Questions about UAV's would almost certainly be on-topic since they are an important concern for pilots.
Questions about construction or operation of small RC airplanes/helicopters/quadcopters are probably outside the scope of this site since it's unlikely we'll maintain a solid base of experts in that area to answer those questions.
I hope that Lnafziger doesn't mind if I quote their answer to "Are model airplanes on topic here?" (with a score of 9 as of this writing):
The site is about Aviation, and I think that model airplanes fit quite nicely here.
Questions about aerodynamics are virtually identical to larger scale aircraft, as well as regulatory type questions about where they can be flown.
I know a lot of pilots (as well as non-pilots) that fly model airplanes, and it would be great if the model aircraft community joined us here since there is a fair amount of overlap. The portion that is more specific can easily be handled with our tag system (in a way similar to Stack Overflow keeping different languages separate via tags).
I would suggest asking and seeing how it goes.
