Hi everyone, so i recently bought a used P2 that came with some fpv stuff, now i want to know what i'm missing, as it's my first drone and first fpv setup i'm prettymuch clueless.
It came with a AVL 55 5.8g videolink trasnmitter, a iosd mini, and two boards where stuff is connected, please see pictures.

I have bought a used gimbal and gopro which is not included in the pictures.
What do i need to purchase?
