Default Rocket Motor rebuild

A motor a I built a couple of years ago. Spins an APC 12X4.7 SF power by a 3S Thunder Power 910 mAh pack thru a no name 20A ESC. Makes about 42oz static thrust. The Sbach it's mounted to weighs in at about 20oz and run 6 min at least. I replaced the stock magnets with N50M's from engineering. The stronger magnets lower the Kv, that and terminating it in Star results in a few turns of big wire lowering the resistance considerably. Anyone know of an OEM 2215 that can spin a 12X4.7 SF on 3S...efficiently? The motor was bought on sale for $11.50 and the magnets cost about $15.00 with shipping.
