RE: feigao XL motors
The amp draw depends on the hull type, the size of the hull, the size of the prop, and how many Volts one is running
Like my ERevo with a 6XL is rated at 110amps max but in reality it has pulled 180amps that I've seen on my amp meter, but I think it has gone higher still
also the UL-1 motor is only rated to 65amps max I think, and those who have data loggers have seen 110amp spikes and this is on a 65 amp esc [:-]
