Narrative:

Departing runway 10 from centennial airport, with a southeast-erly departure, I advised the private applicant to alter course to the right, in compliance with the FAA approved noise abatement procedure. We were climbing to an altitude of 7300 ft MSL before leveling off. At approximately 7000 ft MSL, at the intersection of the 2 roads (lincoln av and jorden rd) I noticed what appeared to be aircraft close to our same altitude, and what I estimated from the size, 2 mi. I pointed out the aircraft to the applicant, and advised a slight turn to the left, en route to the local practice area. Within seconds, the other aircraft maneuvered into what appeared to be a chandelle. I then noticed that the other aircraft was a remote control aircraft. Because of the size of the aircraft, I interpreted the perception to be at a distance of 2 mi. The aircraft was actually only about 200 yds, and in the chandelle maneuver, was now on a collision course with our aircraft. It appeared that the operator was now aware that our aircraft were closing in, and now dove his aircraft to avoid our aircraft. However his aircraft was about 40 ft above ours, and ahead, when he began the dive--and upon passing our aircraft, missed by approximately 15', over the cockpit, diving straight at our aircraft. I took the controls from the applicant and dove our aircraft, while banking to the right about 35 degrees. Altitude lost was about 150 ft. The flight then proceeded west/O incident.

Title: SMA TRAINER ACFT HAS NMAC WITH REMOTE CONTROL MODEL ACFT WITHIN 2 MILES OF CONTROLLED ARPT.

Narrative: DEPARTING RWY 10 FROM CENTENNIAL ARPT, WITH A SE-ERLY DEP, I ADVISED THE PVT APPLICANT TO ALTER COURSE TO THE RIGHT, IN COMPLIANCE WITH THE FAA APPROVED NOISE ABATEMENT PROC. WE WERE CLBING TO AN ALT OF 7300 FT MSL BEFORE LEVELING OFF. AT APPROX 7000 FT MSL, AT THE INTXN OF THE 2 ROADS (LINCOLN AV AND JORDEN RD) I NOTICED WHAT APPEARED TO BE ACFT CLOSE TO OUR SAME ALT, AND WHAT I ESTIMATED FROM THE SIZE, 2 MI. I POINTED OUT THE ACFT TO THE APPLICANT, AND ADVISED A SLIGHT TURN TO THE LEFT, ENRTE TO THE LCL PRACTICE AREA. WITHIN SECS, THE OTHER ACFT MANEUVERED INTO WHAT APPEARED TO BE A CHANDELLE. I THEN NOTICED THAT THE OTHER ACFT WAS A REMOTE CTL ACFT. BECAUSE OF THE SIZE OF THE ACFT, I INTERPRETED THE PERCEPTION TO BE AT A DISTANCE OF 2 MI. THE ACFT WAS ACTUALLY ONLY ABOUT 200 YDS, AND IN THE CHANDELLE MANEUVER, WAS NOW ON A COLLISION COURSE WITH OUR ACFT. IT APPEARED THAT THE OPERATOR WAS NOW AWARE THAT OUR ACFT WERE CLOSING IN, AND NOW DOVE HIS ACFT TO AVOID OUR ACFT. HOWEVER HIS ACFT WAS ABOUT 40 FT ABOVE OURS, AND AHEAD, WHEN HE BEGAN THE DIVE--AND UPON PASSING OUR ACFT, MISSED BY APPROX 15', OVER THE COCKPIT, DIVING STRAIGHT AT OUR ACFT. I TOOK THE CONTROLS FROM THE APPLICANT AND DOVE OUR ACFT, WHILE BANKING TO THE RIGHT ABOUT 35 DEGS. ALT LOST WAS ABOUT 150 FT. THE FLT THEN PROCEEDED W/O INCIDENT.
