Fixed wing flight controller advice

#1

I am currently building a 1.2 meter electric pusher flying wing which I would like to setup for auto flight and am looking for advice on what to use as a flight controller.
My radio is Frsky X9D and whatever receiver is required. Probably a X8R.
I am somewhat Raspberry Pi experienced and have a range available for use, ranging from a Raspberry Zero to a Raspberry 3B+. I have less arduino experience but do have a UNO available.
Can I use the hardware I have available or do I need to acquire an actual flight controller?

Hi,
Yes you will need to get an autopilot board
