Sorry, I have many producers here few kilometers far, so I use local products, but I can tell that for example MVVS 8 works also well, and also Scorpion 3026/710 ... but they are too large for 6sA123 .. you must remember, that you have limited capacity in that battery, and prop 12x6 at ~9000 rpm does not load it too much, so bigger motor is also a kind of dead weight. larger motor is not always more effective since you have iron loses and it depends on mass of the motror.
I would try to select from motors with weigth from 150g to 200g, kv somewhere up to 700, Ri max. 45mohm, I0 max 1.5A
I would say that scorpion 3020 is smalles acceptable, scrorpion 3026 largest .. AXI is somewhere in between golden middle way :- )))))))))
I have very bad experience with chip copies of those motors while flying indoors, so I never tried such motor on large model, so I cannot tell.
Regarding those smaller A123 cells with capacity 1.1Ah, I think it is not anything for us, they are heavy and expensive (for the capacity).
