RC planes have a strip down on the north east corner of 72nd and Indiana. As far as drones, I would check with park service but anything near the Wind site and jeffco airport are considered federal airspace. Unfortunately, drone operators have gotten a reputation of "irresponsible operation" in a lot of the nation. Flying around fire fighting efforts and search and rescue operations. Double check with your county Sheriff's office for more information before risking substantial fines.
I don't know for certain, yet not far from the Wind power plant I often see RC planes being flown. It is illegal around the power plant at least.
