Flies great, about 6 min racing indoors with 2S 650mah. Outdoor has plenty of power and is silent on 2S.

Better late then never... video on 3S 550mah

few words about the components

1. Frame : that's the only twig frame I could find that takes 20mm stack. rigid and well cut. Added washers to preserve the 3D printed canopy.
2. stack : good stack overall for the price but low quality. its a 16mm mm.
3. ESC : I got a damaged grommet, the esc makes the motors hotter then other ESC.
4. VTX : gets super hot and overheats. Lower quality then expected, to be replaced by the tiny rush tank which is amazing !
5. FC : USB same side as xt30, that's annoying
6. motors : super good except they are too heavy for the build and you can't use all the power available. motors get hot with 4S.
7. camera : fantastic product. highly recommended.

Edit about VTX : I had to replace the antenna, VTX now working fine.
