Curious if anyone has tested http://www.kdedirect.com/collections/xf-multi-rotor-brushless-motors/products/kde5215xf-435. I plan on running 18's top and bottom (possibly 16 top 18 bottom, will need to test). MK Bl 3.5 is rated to 60a per BL or 240a total, these peak at 61 under full load with 18's. AWU is 16kg, total thrust is 24.8kg at 50%. KDE's numbers on amps are on the money (bench showed that), at 50% the rig will produce 120 A or so which is half of what the BL can handle. I plan on sending one to holger to test, as well as the 330kv version. The one issue is the rig has to have dual FC for my 333, so that cuts using a Herk out of the equation. My concern is voltage spikes and the event that I will have to ditch one day. My bl3.0 test bench has not kicked any errors, but that's a bench, Not real flying.
