Narrative:

I was instructing from the back seat of a tandem scat tailwheel aircraft (citabria - 7ECA, 180 hp). We were doing wheels lndgs to a full stop, then going again on the 6000 ft runway. The C172SP (with 180 hp engine) was following us very closely on several circuits. Aircraft Y, in turn, was followed by a second C172SP. We announced and made a stop-and-go landing on runway 16. While we were stopped on the runway, north of taxiway D, C172SP (aircraft Y) landed behind us and announced he was holding short. As we were north of taxiway D, there was less than 3000 ft of runway behind us, so I estimate that aircraft Y came within 1000 ft of our stop position on the runway. In retrospect, it was a bad assumption on my part to assume that aircraft Y, who was flying aggressively on our tail, would execute a go around to provide safe separation. A 360 degree turn in the air or a touch-and-go on our part could have prevented the incursion on our position by aircraft Y, who was being reckless. Aircraft Y was using his 180 hp engine to out climb and out run our citabria. If throttled back to 2000 FPM, his speed would have matched ours. While we were the lead airplane in the sequence and had the right-of-way to the runway, defensive flying would have been appropriate to avoid aircraft Y.

Title: A C172SP LANDED BEHIND A 7ECA STOPPED ON THE RWY PERFORMING STOP-AND-GO FOR TRAINING AT GKY, AN UNCTLED ARPT.

Narrative: I WAS INSTRUCTING FROM THE BACK SEAT OF A TANDEM SCAT TAILWHEEL ACFT (CITABRIA - 7ECA, 180 HP). WE WERE DOING WHEELS LNDGS TO A FULL STOP, THEN GOING AGAIN ON THE 6000 FT RWY. THE C172SP (WITH 180 HP ENG) WAS FOLLOWING US VERY CLOSELY ON SEVERAL CIRCUITS. ACFT Y, IN TURN, WAS FOLLOWED BY A SECOND C172SP. WE ANNOUNCED AND MADE A STOP-AND-GO LNDG ON RWY 16. WHILE WE WERE STOPPED ON THE RWY, N OF TXWY D, C172SP (ACFT Y) LANDED BEHIND US AND ANNOUNCED HE WAS HOLDING SHORT. AS WE WERE N OF TXWY D, THERE WAS LESS THAN 3000 FT OF RWY BEHIND US, SO I ESTIMATE THAT ACFT Y CAME WITHIN 1000 FT OF OUR STOP POS ON THE RWY. IN RETROSPECT, IT WAS A BAD ASSUMPTION ON MY PART TO ASSUME THAT ACFT Y, WHO WAS FLYING AGGRESSIVELY ON OUR TAIL, WOULD EXECUTE A GAR TO PROVIDE SAFE SEPARATION. A 360 DEG TURN IN THE AIR OR A TOUCH-AND-GO ON OUR PART COULD HAVE PREVENTED THE INCURSION ON OUR POS BY ACFT Y, WHO WAS BEING RECKLESS. ACFT Y WAS USING HIS 180 HP ENG TO OUT CLB AND OUT RUN OUR CITABRIA. IF THROTTLED BACK TO 2000 FPM, HIS SPD WOULD HAVE MATCHED OURS. WHILE WE WERE THE LEAD AIRPLANE IN THE SEQUENCE AND HAD THE RIGHT-OF-WAY TO THE RWY, DEFENSIVE FLYING WOULD HAVE BEEN APPROPRIATE TO AVOID ACFT Y.
