I suspect you are addressing the right audience? I suspect their risk assessment is based upon the fact RC aircraft have been around for decades, drones more recent, there must be "very significant numbers" of both out in the community, and so far no mid airs. Not saying it can't happen, but there is a lot of air up there and despite the cowboys and kids with RC models and drones, a bingle hasn't happened.
Against a sub 2kg drone I'd back an aircraft every single time!
