INSTRUCTOR PLT WITH TRAINEE IN A PIPER PA 28 HAD NMAC WITH A MODEL PLANE OPERATING WITHIN THE 7G0 UNCTLED TFC PATTERN AT 550 FT AGL. NO EVASIVE ACTION WAS TAKEN BY THE RPTR DUE TO LACK OF TIME.

Narrative

MODEL ACFT OPERATING OUT OF A NEARBY COUNTY PARK WERE OBSERVED NEARBY AND WITHIN THE TFC PATTERN FOR 7G0. RC MODELS ARE HIGH PERFORMANCE AND CLB AND MANEUVER MORE AGILY THAN FULL SIZE LIGHT ACFT. DEPARTING RWY 10 WE WERE NEAR MODEL ACFT ON SEVERAL OCCASIONS WHILE DOING PRACTICE LNDGS; WE EXTENDED UPWIND SO THAT XWIND LEGS WERE E OF THE MODEL FIELD; WHICH IS SITUATED WITHIN THE TFC PATTERN FOR RWY 10 AT 7G0. SOON THEREAFTER WE DISCONTINUED TRAINING AND RETURNED TO BASE. SITUATING AN RC MODEL FIELD SO CLOSE AN ACCIDENT OPPORTUNITY. WITH MODELS OPERATING AT 1200 MSL (500+ AGL) IT WILL ONLY BE A MATTER OF TIME UNTIL A MID-AIR OCCURS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE MONROE COUNTY PARK SVC OPERATES THE 7G0 ARPT WHICH IS ONE HALF MILE E/N E OF THE MODEL ACFT FAC. THE MODEL ACFT OP IS ALSO WITHIN THE COUNTY PARK. THEREFORE; THE ARPT MGMNT WOULD HAVE FULL AUTHORITY OF PERMITTING AND LIMITING THE MODEL ACFT ACTIVITIES. HE ALSO BELIEVES THAT THERE HAVE BEEN OTHER COMPLAINTS FROM LOCAL PLTS. RPTR HAS VISITED THE MODEL ACFT OPERATING SITE AND DISCUSSED THE POTENTIAL DANGER WITH SOME MODEL OPERATORS. THEY ADVISED HIM THAT THEY HAVE NO MEANS TO KNOW THE ALTITUDE AT WHICH THEIR ACFT GO TO DURING AEROBATICS AND THEREFORE; THE MODELS TO EASILY GO UP TO 1000 FT AGL. THE PARK SVC HAS A 400 FOOT LIMIT; BUT IS OBVIOUSLY NOT ENFORCED. HE FURTHER STATED THAT THE ACFT CAN BE IN CONFLICT WITH THE MODEL ACFT AT A MUCH LOWER ALTITUDE SINCE THE LOCATION OF THE MODEL ACTIVITY IS RIGHT UNDER THE NORMAL XWIND TURN AFTER TKOF FROM RWY 10. THEREFORE; THE LOCATION IS IN CONFLICT WITH THE FULL SCALE ACFT TFC PATTERN AT THE 7G0 ARPT.
