Most recent build. still rocking the old reverb frame on 2 of my quads. moved to hdzero on almost all of my 5inch quads. For freestyle the latency is just much better feels like super analog. The motors are a but old i took out of an old race quad thay were fairly new. they are goodventuredrones when i used to fly for them but are basically brotherhobby speedshield 2207.5 1860kv motors. Flys great, still not in love with betaflight feeling and may be switching this over to kiss ultra.
