Tempest Speed Controllers are designed to work in perfect harmony with Tempest Brushless motors, providing reliable operation with a smooth linear throttle response. These speed controllers will also work extremely well with virtually every other brand of brushless motor. These new ESC’s feature an STM 32-Bit Micro-Controller Unit (MCU), an integrated 3-phase gate driver and high-quality MOSFET Power Transistors.
Note from the Team-Legit Tech Bench: These ESCs will do an excellent job of driving the new generation of high-kv brushless outrunner motors. However, in order to do so smoothly, the Motor Type setting must be set to EDF (default is NORMAL). Failure to do this can lead to desyncing of the ESC and motor at high-throttle. Once this adjustment is made, the 32-bit Tempest ESCs provide awesome performance at very reasonable cost. Combined with juicy integrated switching BECs, the Tempest line is Team-Legit's new go-to line of ESCs. Lower-kv motors do not need this adjustment.
All Tempest Speed Controllers come with built-in BEC circuits to provide power to the radio receiver and servos in your model. The smallest 6-Amp model has a Linear BEC providing 5.0 volts at up to 1.5 amps. The rest of the Tempest Speed Controllers, from the 15-Amp 4-Cell up through the 120-Amp 8-Cell model, all have Switching BEC Circuits providing 5.5 volts, with outputs ranging from 2 amps to 8 amps, depending on the model.
