Flying at reduced throttle still sends the max current through the system during those bursts. In many ESC's they will get hotter at a reduced throttle setting than at full throttle. You really need to have a watt meter so you can see what your plane does and don't rely on motor calculators. If in doubt, prop down or use a bigger ESC.
My esc is plenty, doesn't even get warm. Full throttle exceeds motor max amps supposedly by five so I plan on propping down when I get one in. Until then I'll reduce max throttle setting and try to get a hold of a watt meter.
