The Hacker A30 series motors are designed for larger park flyers, 3D aerobatic, and scale models from 24oz to 60oz and utliize 2 to 4 series lipoly batteries. The 14 pole "outrunner" type design creates massive torque, therefore larger direct drive props can be used without the need for a gearbox. These motors feature oversized bearings, curved neo-magnets, and high-efficiency stator design. The A30 motors produce the most power at lower current consumption than other popular outrunner designs.
