    What a frame! Clearly a lot of thought went in to the design of this frame and maximising usable space while still protecting components.
    I mainly build micros, 2 to 3″ and have been searching forever for a *quality* 3″ freestyle frame. The closest I found was by another awesome company, but the alumi frame just left no room for parts.
    The 2 or 3 (if you go 16mm O_O ) stack setup is genius, even large 4 in 1’s like an ORI32 fit with ease leaving room for a real VTX and a split. I can imagine small ESCs would fit on the arms as well.
    The carbon is super high quality and the 4mm main plate inspires confidence, I have not encountered a micro with this sort of crazy stiffness.
    I say micro… It is a chunky lil guy though, my build came to 218g (without battery). I was expecting it to be a little sluggish but was surprised at just how nimble it is, while having a sense of inertia most of my 3″ quads miss which is perfect for freestyle floopin.
    1507 motors and RotorX RX3044T props are giving me around 4 min on an 850Mah 4s and on a similar Mah 3s it still has enough punch for some fun flying. (Gotta use all your batteries right?)

    Sweet freestyle tank frame! Love it!

    Oh yeah, and shout outs as well to Botgrinder for the heads up! posted on 4/20/2018 ;P

    Built like a tank handles like a Ferrari . Most recent crash I impacted nose first full throttle pinwheeled 50yds across pavement and all I had to do was unplug replug and fly away . I wish I had HD footage but my split looses the last 30sec after a heavy crash . Wish we could get this in a 5 or 6mm 5”
