Someone once told me of the N5800, there were three motors they put in that category of testosterone and force. I imagine the other two were also Cesaroni 98mm6XL, as Aerotech stops at 98/15360 for now. Does this sound familiar to anyone? Maybe the imax and the blue or red? Not that I am flying any of these any time soon, but I like to know what is out there. I keep hoping for a higher N5800 altitude record, too.
