the same thing that happens if you overload ANY electronics without a fuse. They blow up and dont work anymore. That's why you always make sure you are over rated on your equipment.

notice the total rated amps,,,,,, 20. that means it's got overhead with a 30 amp esc. Does that mean you can't make it go over, absolutley not, the prop/voltage dictates that, but what it means is that motor doesn't want to be propped so it draws more than 20 amps and the esc is meant to handle 30 in the same manner

i actually using 6 of Torxpower Pro motors http://www.quadcopters.co.uk/?PageID=ShowItem&Item=3536PRO&Desc=Torxpower
but i think it must be the same. if i using 13x6 zoll props then
@cloner what you meant with doesn't want to be propped? do you mean a crash?
i just want to find out if this combination of esc and motor / prop is safe.
another scary issue is the heatshrink covering the esc. i think its not really friendly to heat absorbing and does this mean that in operation the esc can handle even lower ampere rates than described. and burning down even faster?
i know that i will find it out sooner or later but maybe there are some experienced members who could warn me before

the only way i know of checking for amp draw is with a data logger that has current sensing. it kicks out graphs that come from your setup and flying style. in this case, it is logging all four motors in one number, so if weight isn't exact, the weight bearing side can draw more than the non bearing side
the 38.8 amps is spread across 4 times 30 amp esc's, 120 amps and i'd start to worry
