it's nothing new. i put it up so i don't have to remember it and can show it to others.
also, i leave PID setting for someone new to fpv.

it flies faster with 3" props, but as you can see in the video, more speed is not what i want.
so, use 2.5" props if you have appropriate space for it, like the space i'm flying in.

i don't intend to fly far with it and i ran out of crazybee f4 10a board with built-in RX. otherwise i would use it with this setup
56g dry
Alexandre Arvinte's 65mm frame
12a Geprc board
diatone mamba 1105 5500kv
xm+ receiver
aio camera
Avan 2.5" props
3s 450mah batteries

PId is ok. ( in the picture )
