Narrative:

Reporter delivering unfamiliar aircraft. Initial takeoff on grass taxiway and runway, with no problems. Stopped at pike bluff for fuel. Upon runup and hold short line, aircraft crept into runway area. At the same time a twin was on short final, had to extend over my aircraft to land safely. In an unfamiliar aircraft, perform runups with more room to spare (an initial brake check at ramp was ok) just in case. Another factor was that I did not have correct radio frequency set on ramp, so I never heard the twin's call to final. Also, didn't see them due to high wing aircraft.

Title: DURING ENG RUNUP AT HOLD SHORT LINE, RPTR ACFT CREPT ONTO RWY REQUIRING LNDG ACFT TO LAND OVER THE TOP OF RPTR ACFT. INCORRECT UNICOM FREQ ON RPTR RADIO.

Narrative: RPTR DELIVERING UNFAMILIAR ACFT. INITIAL TKOF ON GRASS TXWY AND RWY, WITH NO PROBS. STOPPED AT PIKE BLUFF FOR FUEL. UPON RUNUP AND HOLD SHORT LINE, ACFT CREPT INTO RWY AREA. AT THE SAME TIME A TWIN WAS ON SHORT FINAL, HAD TO EXTEND OVER MY ACFT TO LAND SAFELY. IN AN UNFAMILIAR ACFT, PERFORM RUNUPS WITH MORE ROOM TO SPARE (AN INITIAL BRAKE CHK AT RAMP WAS OK) JUST IN CASE. ANOTHER FACTOR WAS THAT I DID NOT HAVE CORRECT RADIO FREQ SET ON RAMP, SO I NEVER HEARD THE TWIN'S CALL TO FINAL. ALSO, DIDN'T SEE THEM DUE TO HIGH WING ACFT.
