    OMG OMG OMG Im in love – my first 3″ build and have loved building this – such a simple but awesome idea to be able to do a dual stack – comes together so nice.I got this for mid to long range adventure flights, can get 6-7 mins on 1500 4s Did my first maiden tonight – THANKS BILL – love it (and thanks Botgrinder – if it wasnt for his vid id have missed it. search for it on the tube of you in about an hour 😉

    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”

    Just built and shipped a 3AF for Zoroe not FPV. Test flew it for before shipping and just wow. I’ve never had a 3″ float like this one. Just punch and float. Thanks to BQE for hooking me and Zoroe up with the frame for the video. Now I just need to get one for myself.
    Parts used for the Build:
    BQE 3AF
    Diatone Succex 20×20 stack 35amp esc & F4 with VTX up to 200
    Hobbymate 1505+ 4500kv (really nice motors)
    Caddx EOS 2

    This is/was my go to 3” learned to fly with it. I have Lumiere Lux Stack, hglrc flame 1407 motors, and Mach3 VTX with Gemfan 3052’s. It is super durable and fly’s great! Highly recommend if your wanting a bullet proof 3”
