I've been putting in some packs on the Avantquads Leggero 5" and the Emax 2306 2750kv motors since my initial review. I'm even more impressed with the Leggero. For the Emax, I think my initial impressions were right.
The exact quad I am flying is the Bind-n-Fly with Returner R3 motors. This quad put in a 14.1 second time on MultiGP UTT1 with me at the sticks. With a competent pilot, it'd be faster ;-)
