This is my armattan build, these are the components:
450/650 mah tattu, 4s
Flywoo goku f405 aio, 20 amps
Tbs pro v3, 800mw vtx
Iflight xing 2 1404 4600kv motors
Vifly mini Finder buzzer
Foxeer elrs lite receiver
Runcam racer v3 mck.
Foxeer lollipop 4+ because it looks good.
Xt30, 16awg battery cable.
And I want to add my runcam thumb camera on top later!
I use a radiomaster zorro and fatshark dominator v2 goggles.
It flies great! I like its small and still powerfull. Flight time is about 5 mins probably. Flew only 2 times so i have no idea about the freestyle specs.
