Construction
ATR 1 and 2 were both built to test my homemade altimeter, they both had a motor end made from cardboard with plywood fins, the Altimeter bay and nosecone came from previous rockets. ATR-1 came from sKrabble, when that spacked ATR-2 came from Krown Flyer.
Flight History
1) First flight of ATR-1, Launched at BIG EARS, Cambridgeshire on 2nd June 2013 on a G58WH motor to 700ft. It was also the first test flight of my homemade altimeter (SBA-1), rocket spacked as I set too long delay, homemade altimeter survived but rocket non recoverable and commercial RRC2 broken. Most of the flight data up to about 2 sec before Apogee was overwritten but apogee and decent recovered.
2) Rocket rebuilt to same spec and flown as ATR-2 at MRC, Tycross on 9th June 2013 on a G115WT motor to 770ft. It was the second test flight of SBA-1 homemade altimeter, flight successful, full flight data returned, compared with a raven and only 30ft difference.
3) ATR-2, Launched at EARS, Cambridgeshire on 7th July 2013 on a H125CL motor to 2000ft. Third test flight of SBA-1 homemade altimeter, recovery non optimal as parachute did not unfurl. Altimeter bay cracked and homemade altimeter restarted overwriting all flight data. Altitude determined from Raven
4) ATR-2, Launched at Black Knights, Oxhill on 21st July 2013 on a H125CL motor to 1901ft. Forth test flight of SBA-1 homemade altimeter, flight successful, full flight data returned, compared with a raven and only 50ft difference.
5) ATR-2, Launched at IRW, Fairlie Moor on 18th Aug 2013 on a H125CL motor to 1934ft. Fifth test flight of SBA-1 homemade altimeter, flight successful, full flight data returned, compared with a raven and only 36ft difference.
