I agree. My first thought was the same. We are looking for numbers around 230 for the outrunners. I haven't looked close but maybe this is designed for 12S packs? That would also account for the lower max current. The combination of Kv=170 and 60 Amps won't work in a 10S, 5 kg pattern plane. Is the max power specified? We need about 3KW and that would be 50V at 60A. 14 cells?

Steve, I can't make Lancaster on Saturday, but I'll probably come out on Sunday if the weather is good, so I can bring you some grease if you still need it.
