Regarding battery I am on 95% ... but it is A123, so does not matter.
Regarding motors, I thought it is not so bad, but the guy from AXI wanted to see what we do with them, because when I told him we have 6 cells with 12x6 on AXI 2826/12 he told me it MUST burn. He did not know that 6sA123 on governor is something else, but anyway, he tried temperature and he told me we have to go with the temperature down. The only reason for that is bearing which is not preprared to work full time at so relatively high rpm without oiling (so not problem with magnets, winding, efficiency).
But my Axi after whole seasone (~300 flights on that one model) looks like new. So I do not know, it looks good, and you are probably right, but if I should go to higher power (if), I thing it will really need bigger motor. Just to be sure that it is safe and that I can without any questions fly it whole season in seriouse uninterrupted practice and competing.
