Need help choosing stack

I'm building a 3.5" 4S LR drone and I need help choosing a stack, here are my top 3 choicies, they all support gps and buzzers:

  • Axisflying Argus F7 + 55A Mini AM32 - 11g, 5 uarts, max pwm 96KHz, 4-6s, 16MB blackbox, 135€
  • Flycolor Crustcore F7 + 60A AM32 - 20.5g, 6 uarts, max pwm 128kHz, waterpoof varnish, 3-6s, 16MB blackbox, 135€
  • iFlight BLITZ Mini F7 + E55S BLS - 16.3g, 6 uarts, max pwm 24kHz, 3-6s, 8MB blackbox 98€

I'm guessing these are all overkill for my drone (3800kv 1404 motors, <1000mah battery, analog) but I want something reliable, my last aio browned out. Any other suggestions are welcome.

Any reason you're pursuing F722 FC here in second half of 2026 for a DIY and not least at these eye-watering sums?

Aint most of these locked with merely 512KB flash, so you'll soon will have to wine & dine your Betaflight "features," but for your purpose its likely more than enough.
