Hmm , I built an Happymodel Mobula8, and used a 1S Walksnail VTX, it's a good combination, maybe your BetaFPV Pavo20 would be better suited for a smaller lighter 2S battery as that would better suit the 11000Kv motors, it would certainly be easier to tune and fly better.
Nice; I think 4S might be too powerful with that little weight (depends on your motor KV too). 3S is already pushing it for the KV of my motor. Also make sure that the AIO board that you're using can support 4S. I blew a cap on mine cause I put in 4S lol
