SPEED 280 to 300 Size Brushless Motors

280 Size Brushless Motors

22mm diameter - smaller than a brushed SPEED 280. A 280 motor is 1.5 oz. Mini AC is 1.7 oz. But Mini AC's behave like 480's! They are more efficient than 480's and they put out 480 size power with less current flow than 480's. For 10 to 30 oz. airplanes. 48mm long, 2.3mm shaft. Will mount anywhere a SPEED 400 or 480 was mounted and will fit SPEED 400 gearboxes. Has the same mounting bolt pattern and shaft size as a SPEED 400. Carbon outer case. Use 18 amp Jeti Brushless Motor Controller 18-3P.
