Help with replacement F.C.

Hi All,
Looking for some guidance around selecting a replacement F.C.
Got a Lumenier QAV250, not flown it for a couple of years, been mainly flying TBS Discovery Pro, DJI Mavic and the ImmersionRC 285.
Would like to get the QAV up and running again, but the Naze32 Rev5 is too old for the latest F.C. software (Cleanflight or Betaflight).

The current build is;
1. Naze32 Rev5
2. T-motors 1806 2300
3. Afro 12a ESCs
4. Lumenier is fitted with their Fury PDB, which includes the TBS Core to give OSD.

I’m looking to replace at a minimum the F.C. and if possible keep the rest of the electronics, but open to suggestions (ESCs etc)

Many Thanks,
Scottie
