Pilot of an RV4 maneuvered the aircraft at a high airspeed and then climbed in a 45 degree pitch up attitude shortly after takeoff, at a non tower airport. The pilot reports that the intent of the 45 degree climb attitude was for noise abatement purposes and that aerobatic flight is not clearly defined.

Narrative:
On departure from ccb, I accelerated to 160 mph and pulled up into a 45 degree climb to 3000 ft MSL (1600 ft AGL) to begin a left 270 degree turn to exit the traffic pattern and conform to noise abatement procedures for ccb runway 24 departure. There were no other aircraft in the pattern, landing, or taking off. There was 1 aircraft approaching from the north which never came within 2 mi of my RV4 and then, when I had already exited the pattern and was approximately 2 mi northwest of cable. No danger or conflict existed nor was any evasive action required by any aircraft. There is a question if a 45 degree pull-up constitutes aerobatic flight. I think that more definitive guidelines should be developed to determine what and when constitutes aerobatic flight when noise abatement and other factors are considered. A 45 degree climb as part of a reverse cuban would be aerobatic while a quick climb for terrain and noise abatement would not be.
Original NASA ASRS Text
Title: PLT OF AN RV4 MANEUVERED THE ACFT AT A HIGH AIRSPD AND THEN CLBED IN A 45 DEG PITCH UP ATTITUDE SHORTLY AFTER TKOF, AT A NON TWR ARPT. THE PLT RPTS THAT THE INTENT OF THE 45 DEG CLB ATTITUDE WAS FOR NOISE ABATEMENT PURPOSES AND THAT AEROBATIC FLT IS NOT CLRLY DEFINED.
Narrative: ON DEP FROM CCB, I ACCELERATED TO 160 MPH AND PULLED UP INTO A 45 DEG CLB TO 3000 FT MSL (1600 FT AGL) TO BEGIN A L 270 DEG TURN TO EXIT THE TFC PATTERN AND CONFORM TO NOISE ABATEMENT PROCS FOR CCB RWY 24 DEP. THERE WERE NO OTHER ACFT IN THE PATTERN, LNDG, OR TAKING OFF. THERE WAS 1 ACFT APCHING FROM THE N WHICH NEVER CAME WITHIN 2 MI OF MY RV4 AND THEN, WHEN I HAD ALREADY EXITED THE PATTERN AND WAS APPROX 2 MI NW OF CABLE. NO DANGER OR CONFLICT EXISTED NOR WAS ANY EVASIVE ACTION REQUIRED BY ANY ACFT. THERE IS A QUESTION IF A 45 DEG PULL-UP CONSTITUTES AEROBATIC FLT. I THINK THAT MORE DEFINITIVE GUIDELINES SHOULD BE DEVELOPED TO DETERMINE WHAT AND WHEN CONSTITUTES AEROBATIC FLT WHEN NOISE ABATEMENT AND OTHER FACTORS ARE CONSIDERED. A 45 DEG CLB AS PART OF A REVERSE CUBAN WOULD BE AEROBATIC WHILE A QUICK CLB FOR TERRAIN AND NOISE ABATEMENT WOULD NOT BE.
