The new Hacker A20 Series motors are the latest design using outrunner technology. Specifically engineered for high power and high efficiency using the proprietary components of the finest quality.

• Outrunner design uses no gearbow for lower weight
• 5-7 time nore torque than direct drive inside runner
• High torque means large propeller for more trust
• Rotating can/endbel provide excellent cooling
• Better cooling means very long flights with LiPoly cells
• Versatile mounting options (front or back mounting)

A20-S- Developed for 4-8 oz. Indoor Slowflyers and Indoor Aerobatic models with 2 cell LiPoly batteries. The 12 pole “Outrunner” type design creates MASSIVE TORQUE, therefore larger direct drive props can be used without the need for a gearbox. This motor features Oversize bearings, Curved Neo-magnets, and High efficiency stator design. These motors produce the most power at lower current consumption than other popular Outrunner designs!. Included are 2 prop adapters, plywood and aluminum motor mounts, screws and 2 spare shafts. The motor uses a standard 3mm output shaft.
