I don't know what lipos you are using, but with TP5300s, the AXI F3A turns the 22x12 at about 5700 rpm static (on the ground) at about 76 amps. 21x13 at 6040 rpm static at 72 amps. 20x15 at 6100 rpm static at 76 amps. In the air, you can add about 400 rpm to these figures.
If you are using newer 20C type lipos, you will get slightly better figures on rpm due to the 20C cells holding voltage better than the older type cells. Performance is noticeably better according to my friends who are using the newer cells. I have not flown them.
