So far I'm really impressed with this frame. Simple, elegant and durable, although it's a little tight on space inside for a freestyle frame - just enough room to fit my usual set of components - a Helio Spring FC with a 4-in-1 ESC, TBS Unify Pro HV, and Crossfire Nano receiver. It feels really balanced and has a nice CG - similar to a Chameleon or Rooster, but with better separation bewtween the front and rear props, as its arm geometry is not as "squished" as some other freestyle frames - while still managing to keep props out of the HD video. Relatively easy to build, although you do need to manage your stack height if using a 4-in1 ESC. Wide arms and relatively low deck height means it's probably better suited to individual ESCs on the arms with an FC with a builti in PDB, but still workable for a 4-in-1.
