E-Flite Park 450 Brushless Outrunner Motor (890 kV)

This is the E-Flite Park 450 Brushless 890Kv Outrunner Motor.  This motor is ideal for 3D models weighing 15-25 oz, or scale parkflyers weighing 20-30 oz.  This motor is very quiet, and efficient.  It offers a large amount of torque, and weighs in at just 2.5 ounces (72g).  This small outrunner has great power and makes an excellent sport motor for the E-Flite Mini Edge and Mini Funtana size 3D park flyers, and for scale park flyers like the P-47.  If you are looking to upgrade from a 370 or 400 motor, this is the way to go!
