I built this using an F7 Omnibus FC and the recommended Airbot 4 in 1 ESC and all I can say is that it's a fantastic setup. Assembly was easy. I have used Emax 2205 2300kv motors in addition to 1300mah Ovonic 100c Lipo. Then hooked it up to an AKK VTX in addition to a Foxeer camera. Finally, I used an ultra-small FrSky receiver to pair with my QX7 controller. The basic PIDs are great and I had to do a little manual tweaking other than moving the motor in the right order and changing the direction of the motor. Note that F7 FC will get hot so be prepared or just use F4. But this shot is great.
