Hacker E3-49 Brushless Motor

These motors combine 3-time FAI F5D World Champion Hacker’s precision engineering with E-flite’s recognized reliability. New Hacker E-Series Brushless Motors are a unique blend of high performance and competitive price, braced by Hacker’s state-of-the-art 2-pole slotted stator design, which produces high levels of torque and rpm at lower current draws.

Features:

• Precision engineered in Germany by proven World Champions
• Excellent Motor for small airplanes between 10 oz 18 oz (280 g 510 g) and 3D models between 12 oz 15 oz (340 g 425 g)
• Combines ultra-high power and super-efficient design
• State-of-the-art 2-pole slotted stator design for high power output
• Robust all-metal construction featuring high-grade alloys throughout
• Machined heat sink fins and ventilation holes on each end bell provide excellent heat dissipation at high levels of power for maximum reliability
• Multiple mounting hole spacing to fit into most GWS and E-flite? gearboxes 14 mm and 17 mm spacing
• Ideal for park flyers, miniature helis and the Mini-T
• Two mounting hole spacing options
