That's 1/8 scale ESC territory.
ESC's aren't like the old microswitch stuff where you could just have it switch on for a blast, even if your run is 2 seconds your ESC still has to receive six inputs from the hall effect sensors to calculate and enact three energized windings per rotation of the rotor. At 50,000 RPM this is 5000 inputs and 2500 outputs per second. Not to mention that your ESC's internal power supply for its processor is meant to run within a certain voltage range and 6s can and will overdrive the circuit into burning the board up. I would just get an 1/8 unit and remove the cooling fan and most of the heat sink to save weight.

Highest voltage equals more weight , and the voltage doesn't mean anything if the esc can't deliver it properly, the hit off the line is where most fall short, it's all about power delivery
