Super easy to build. I use a 20x20 stack... And as you can see in the pics, the usb port aligned perfectly. I use a XM+ but will switch to a crossfire nano soon. Also the frame is perfectly designed and resistant. Lastly I love the canopy. Really.

With stock BF 4.2 settings, a 700 4S, this thing rips to heaven! And you get the throw thanks to the heavier weight.

Finally these 1404 motors are not the fastest out there. You got almost cinewhoop tyep of control near the lower end of the throttle. But you can push a d push the throttle and they swallow the amps like champs!

Nice flyer
