an ultralight :-) the buildweight is 30g
its pretty minimalistic, it works great - not that much needed for good performance. low rpm rotor authority is a new world compared to a 50g quad on 1103 motors.

it has super inexpensive electronics, the design of the electronics seems mostly the one from fishpepper.de. the electronics are branded by vivafpv and theres tbs written on it. reasking them about pinout, they provided wrong informations... they hasnt an idea about the product xD strange
anyway it works decent :-) i love how this buidl performs :-)

currently in use with betaflight 4,0 performance edition for f3 (but without rpm filtering)

-f3 with onboard spi, blackbox storage, without osd
-4in1 esc 5a 1-2s
-rubycon 25v 220uf
-eachine 800tvl 25mw aio
-monopole antenna 12,99mm active element for r3
-hq65mm
-brotherhobby r3 1103 8000kv
-sticky x frame

used with some 300mah2s turnigy nanotech
