It's not pretty, or light, but it's fast. Not just full throttle punch-out fast, but fast around the track. Yes the motors are way too heavy for the skinny floss arms, but I've got spares. Yes the motors pull 160 amps at full throttle, but if you can manage the throttle, the efficiency isn't bad. On the bench they make 700g of thrust while only pulling 13.3 amps with cyclone 5046, which is pretty amazing actually.

Betaflight 3.2's dynamic filter is amazing. If you haven't tried it, you should. I am able to remove all the notch filters on most of my quads when I update to 3.2 rc4. The feel in air is great, and paired with the top mount battery, this is quickly becoming my favorite race quad.
