This is the largest offering in the Champion line, currently flying wing spec motor but also usable for 280 and 300 class miniquads.
The large stator size here is aboslutely insane on this motor. As with the F80, this motor is striking in it's efficiency on 5" and even light weight 6" props, but the taller stator definitely delivers more power to the prop, especially at the heavier loading. On the 6x4 this motor delivers a whopping 1800g of thrust at only 35A sustained current and managed to pull over 2kg on the 6x4.5x3 but at an insane 50A peak and 47A sustained. The motor didn't seem to have any issues handling the current, getting no warmer than any of the smaller motors under 35-40A. On a big rig capable of handling a larger battery and appropriately rate ESC, these motors would provide some insane power. Unforutnately I didn't have any 7" props for testing, but clearly this motor has the torque to handle ligher weight dual blade 7" props no problem based on the 6x4.5x3. Definitely some interesting work here from Cobra.
