The next generation of ESCs from iFlight has arrived. These new 55Amp BLHeli32 BLITZ 4in1 ESCs can handle even the most amp-hungry motors. Lager Mosfets and bigger PCB for maximum heat dissipation. Powerful 55A for 2-6S batteries and 20x20 mounting pattern. The perfect match for the BLITZ Flight Controller series.

July 31, 2024: Version updated. Since BLheli32 Configuration is closed due to regulatory issues, if you need to adjust the parameters of this ESC, please download "BLHeliSuite32Test".
