I’m using these motor on various small EPP flying wings (i.e., HEE Wing, Scythe, Sky Shadow) for speed flying, and the performance is excellent. The motors run cool and throttle response is smooth and linear. For excitement, use a 4S 1300 75C battery, 50A Flycolor Francy 50A ESC, and an APC 5.7x3 Sport Prop. Get ready for serious speed.
Excellent quality, very good power, and at this price, you can't do better. Shipped the the same day. USPS caused the only issue and delivered slowly.
